Nano microporous insulation boards for high-temperature industrial applications

Our Products

Nano microporous insulation board product series

Nano microporous insulation board is a board-like inorganic insulation material with very low thermal conductivity and good processing characteristics, especially suitable for applications with high requirements for energy conservation and environmental protection, especially in high-temperature applications where the thickness or weight of the insulation material is limited. This material has advanced technology, high economic benefits, excellent flame retardancy, and meets the industry standard of “A level” fire resistance rating.
Available in various sizes and specifications: length and width can be freely selected within a certain range, with a thickness of 1 to 50 millimeters, and multiple models are available for selection
Rich external packaging forms: Customers can choose nano microporous insulation boards without packaging, or choose different packaging materials according to actual application needs. By selecting wrapping materials, the strength of the nanoboard can be enhanced, dust during installation can be reduced, and certain waterproof functions can be achieved. Optional wrapping methods: PE shrink film, aluminum foil wrapping, aluminum foil bonding, fiberglass cloth wrapping, composite with mica sheets, etc.
Mold customization: Customizing molds enables customers to accurately obtain the required product dimensions, thereby minimizing cutting waste. For large orders, customized molds have significant economic benefits for customers.
Typical application scenarios of nano microporous insulation boards include roller kilns, tunnel kilns, lithium electric kilns, aluminum electrolysis tanks, aluminum melting and insulation furnaces, glass kilns, incinerators, well furnaces, heat treatment furnaces, cracking furnaces, lifeboats, electric furnaces, etc.

Vacuum insulation panel with nano microporous core
Vacuum Insulation Panel (VIP)

Vacuum Insulation Panel (VIP)

Vacuum Insulation Panel (VIP) is a highly efficient insulation material that combines microporous technology and vacuum technology by vacuum encapsulating the microporous insulation core material mainly made of fumed silica into a high resistance diaphragm bag. The material has a very low thermal conductivity (typical value: 0.004 W/m K), good cold insulation effect, long service life, and usually can reach over 50 years. The board surface and board edge are flat, which can reduce the heat leakage at the edge as much as possible. It is easy to install and transport, and has excellent anti-aging function. Even when the vacuum is lost, this material still has excellent thermal insulation performance, and has a very low expansion rate. The gas-phase silica core board uses environmentally friendly materials, which can be recycled and reused, ensuring safety and environmental protection.

Why engineering buyers trust Products List

Anchor-tech track record

Each product family on this page exists because a specific industry or installation requirement generated enough demand to justify a dedicated production run. Rigid board was the original Anchor-tech product from 2014 and remains the highest-volume SKU. PE-faced board was added in 2016 for a clean-room food-processing customer that needed washable insulation behind process ovens. Aluminium-foil-faced board followed in 2017 for marine HVAC insulation. Glass-fibre fabric-faced board was added in 2018 for petrochemical customers whose vibrating equipment was destroying the aluminium skin. Pre-formed arcs entered production in 2019. Custom-formed 3D parts, powder grade, and VIP followed as customer requirements dictated. The matrix on this page is therefore not a generic product catalogue — it is the output of ten years of customer requirements aggregated into a manageable set of standard configurations.

Anchor-tech track record

All products on this page are pressed at our Guangzhou facility from the same fumed-silica master batch — the chemistry is consistent across standard board, laminated grades, pre-formed arcs, custom 3D parts, and powder grade. This is the operational advantage of working with the original equipment manufacturer: a steel mill that orders standard board for one project and formed ladle backup panels for another project receives material with the same lot-traceability chain and the same thermal-conductivity verification. Each product is shipped with a mill-test report keyed to the production batch; if a customer quality team requests verification against the lot, the archived sample is re-tested on the same heat-flow meter that measured the original lot.

Anchor-tech track record

The numbers on this page are realistic, not optimistic. Thermal-conductivity values are quoted as the lot-average from four-temperature-point heat-flow-meter verification (200 / 400 / 600 / 800 °C), not as a marketing single-point estimate. Maximum service temperatures are quoted as continuous-operation values, not as short-term peak values. Standard sizes and thicknesses are quoted as the stocked production matrix, not as theoretical capability — anything outside the matrix is custom and carries additional lead time and cost. Compressive strength is quoted as the value at 10% deformation per ASTM C165 — the same test method our quality-control lab uses for pre-shipment verification. We do not publish performance numbers we cannot verify against our own production lots. Where a customer specification falls outside our published envelope, we say so at the quotation stage rather than promising performance we cannot deliver.

Frequently Asked Questions

Quick technical and commercial answers about Products List for engineering buyers, procurement teams, and installers. For project-specific questions not covered here, contact our application engineering team.

Three questions narrow the field. First, what is the hot-face operating temperature on the cold side of the working lining — below 80 °C means VIP territory, 600–950 °C is the standard and laminated board sweet spot, and 950–1100 °C requires board with reduced opacifier loading. Second, what geometry does the host equipment have — flat surfaces take standard board, cylindrical surfaces take pre-formed arcs or flexible sheet, complex 3D parts take formed shapes, and gap-fill applications take powder grade. Third, is there a skin requirement — clean-room or food-grade service takes PE film, marine or HVAC service takes aluminium foil vapour barrier, and high-vibration or abrasive service takes glass-fibre fabric. The product matrix on this page covers the standard configurations; our application engineering team responds within 24 hours on sizing questions for installations outside the matrix.
The microporous core is the same — fumed silica with opacifier, pressed to 220–280 kg/m³ density. The difference is the skin. Standard board is bare, supplied without any surface treatment; it is the lowest-cost option and the right choice for concealed installations (inside furnace casings, behind refractory linings, inside vessel shells). PE film-faced board has a 50 µm polyethylene film laminated to both faces, making the surface washable and food-contact-safe — the right choice for clean-room process equipment, food and beverage service, and any installation where wash-down is part of the operating procedure. Aluminium-foil-faced board has a 0.05 mm aluminium foil skin encapsulating the board, providing a fully sealed vapour barrier — the right choice for marine service, HVAC, and any installation where moisture ingress or radiant back-loss is a concern. Glass-fibre fabric-faced board has an E-glass or S-glass woven fabric on both faces, providing mechanical robustness against vibration, abrasion, and incidental foot traffic — the right choice for petrochemical vessels, vibrating pipework, and mobile equipment.
Yes — sample shipments are part of our standard technical engagement. A typical sample package contains 4–6 pieces of 100 × 100 mm or 150 × 150 mm board at the requested thickness, plus a printed technical data sheet, MSDS, sample mill-test report, and quotation letter. Sample fees depend on configuration (typically USD 50–150 per sample kit including DHL / FedEx express freight). Sample fees are fully credited against the first commercial order above 1 m³. Sample shipments go by DHL / FedEx / UPS and reach European or North American destinations in 4–7 working days from our warehouse. For evaluation against high-temperature service, customers sometimes ask for accelerated thermal-cycling samples; we provide 200 × 200 mm or 300 × 300 mm pieces at a slightly higher sample fee for that case.
At 25 °C, our standard board measures 0.020 W/(m·K) against 0.040 W/(m·K) for typical 128 kg/m³ ceramic-fibre blanket — board is roughly twice as efficient. The gap widens with temperature: at 200 °C, 0.024 vs 0.070 W/(m·K) — three times as efficient; at 400 °C, 0.029 vs 0.130 — four times; at 600 °C, 0.038 vs 0.190 — five times; at 800 °C, 0.050 vs 0.270 — five times. The gap widens because microporous board has a steeper density-driven drop in gas-phase conduction, while ceramic-fibre blanket is dominated by solid-fibre conduction that rises sharply above 400 °C. The practical implication is that microporous board at 30 mm replaces roughly 150 mm of ceramic-fibre blanket at equivalent heat-stopping duty in a 600 °C furnace backup. Pricing reflects the engineering value — microporous board costs more per square metre at the same thickness but less per unit of heat-stopping duty.
Our standard size matrix covers 1000 × 1200 mm panels at thicknesses 10, 15, 20, 25, 30, 40, 50 mm. Specifications outside this matrix are handled in two ways: small quantity (under 5 m³) orders are cut from stock panels on our CNC cutting cell with a 5–10 working day lead time and a small-batch cutting surcharge; large quantity (above 5 m³) orders are typically scheduled as a custom pressing run with a 15–25 working day lead time. Custom panel sizes above 1200 × 1500 mm require tooling change and a 25–35 working day lead time. For formed 3D parts and pre-formed arcs, the geometry is typically the customer’s drawing, with lead times as quoted under Customized. Our standard production capability does not extend to continuous service temperatures above 1100 °C or to panel thicknesses below 6 mm — these are firm production boundaries, not flexible tolerances.
Each production lot ships with a mill-test report documenting density, thermal conductivity at 200 °C and 400 °C, dimensional tolerance, and compressive strength. Compliance documentation per shipment includes a REACH declaration (chemicals regulation), RoHS 2.0 third-party test certificate (hazardous substances restriction), asbestos-free declaration (per WHO and OSHA standards), CE marking for the relevant product families, and EN 13501-1 A1 fire classification documentation. We retain archived samples from every production batch for 24 months; if a destination customs authority or a customer quality team requests verification against a specific lot, we can pull the archived sample and re-test. For industries with stricter traceability (pharmaceutical, aerospace, nuclear), we run dedicated production batches with 100% inspection and per-piece serial-number traceability at an additional per-piece price uplift.
Standard warranty is 12 months from ex-works dispatch against manufacturing defects. If a customer reports a field issue, we ask for photographs, installation records, and the lot number; we pull the archived lot sample and re-test in our lab. If our product is at fault, we ship replacement material at our cost including freight and cover reasonable installation labour. If our product is clear, we share the test data with the customer and jointly investigate the installation condition. Beyond warranty, we offer application-engineering support throughout the life of the installation — questions about thermal-survey interpretation, retrofit sizing, or service-life extension are answered by the same application engineering team that ran the original design engagement. There is no fee for post-shipment technical support; customers typically engage with us over WhatsApp, email, or scheduled video calls.
