Import Aluminum Silicate Board And Felt / Ceramic Fiber — Buy in wholesale FOB from Supplier in China

The aluminum silicate board and felt from Bestar (Tianjin) Trading Co., Ltd. is a ceramic-fiber insulation system produced from blown or spun alumina-silica fibers, rated for continuous service up to 1260 degrees Celsius according to the source description. The material is supplied in rigid board form and flexible felt or blanket form, giving engineers the option to line flat furnace walls, wrap curved vessels, or seal expansion joints within the same thermal envelope. Bulk density, fibre index, and shrinkage characteristics should be confirmed with the supplier for each grade, as these determine compressive strength and insulation efficiency under cyclic heating.

Standard composition for this product category falls within the aluminosilicate family, typically 45-55 percent alumina and 45-55 percent silica with trace iron, titania, and alkali oxides. Fibre diameter ranges from 2.5 to 5.0 microns for blown product and 3.0 to 4.5 microns for spun product, affecting both handleability and respiratory hazard classification. Permanent linear shrinkage after 24 hours at maximum rated temperature is typically 3-4 percent for standard-grade blanket and 2-3 percent for high-purity board. Thermal conductivity at 800 degrees Celsius is generally 0.20-0.25 W/mK for medium-density blanket and 0.18-0.22 W/mK for rigid board, though Bestar's exact values must be requested.

Buyers are typically operators of heat-treatment furnaces, petrochemical reformers, power-generation boilers, and aerospace test cells who need to reduce shell temperatures and fuel consumption. The flexible felt suits irregular surfaces and temporary repairs, while rigid board provides dimensional stability for doors, roofs, and burner walls. The source mentions FOB and CIF shipping options from Tianjin, but does not state MOQ, price, or lead time. Bestar (Tianjin) Trading Co., Ltd. should be asked for their specific density grades, standard panel dimensions, and whether they supply complementary anchoring systems or ceramic-fiber module sets for complete furnace lining.

Bestar (Tianjin) Trading Co., Ltd. is registered at 801-A North of Financial and Trade Center, No. 6865 Asia Road, within the Dongjiang Bonded Port area of Tianjin Free Trade Zone, Tianjin, China. The location inside a bonded port offers potential advantages for export customs clearance and VAT rebate efficiency, though buyers should verify whether the company handles logistics directly or through a freight forwarder. The trust tier is listed as harbor, and the response metrics show zero recorded response rate and zero average response hours, indicating that email enquiry alone may not yield rapid feedback.

The company is positioned as a trading entity rather than a manufacturer, which means product consistency depends on their quality-control relationship with the producing mill. No factory name, production capacity, workforce size, or history is provided in the source. Buyers should request the actual manufacturer's details, a copy of ISO 9001 or ISO 14001 certificates if claimed, and material safety data sheets for the ceramic-fiber product. Because ceramic fiber is classified as a possible carcinogen by IARC when respirable fibres are in place, confirm with Bestar whether their product is refractory ceramic fibre or a low-biopersistence alkaline earth silicate wool, as regulatory acceptance differs by jurisdiction.
