Import 25mm Aluminum Coated Glass Fiber Needle Mat — Buy in Bulk from Supplier in China

The 25mm aluminum coated glass fiber needle mat from Jotex Composite Materials Co, .Ltd. is an industrial insulation material based on E-Glass fibers with a bulk density of 133 kg/m³. The 25 mm thickness provides thermal barrier performance and the aluminum coating adds radiant heat reflection. Stitch bonding holds the needle-punched structure together rather than chemical binders, which matters for high-temperature applications where outgassing must be minimised. This construction is typical of exhaust insulation, industrial furnace seals, and fire-protection systems where glass fiber mats serve as the core barrier.

E-Glass (electrical grade glass) offers a balance of thermal resistance, mechanical strength, and chemical stability that makes it the standard reinforcement in composite and insulation applications. The needle-punch process orients fibers in three dimensions, creating a compressible but resilient structure that recovers after compression. The aluminum coating, applied to one or both faces, raises the surface emissivity and reflects infrared radiation, improving the effective thermal resistance in radiant heat environments. Standard industry grades for similar mats range from 100 kg/m³ to 200 kg/m³ density, so the 133 kg/m³ figure sits in the medium-density range suitable for general industrial insulation rather than extreme compression resistance.

Buyers in automotive exhaust after-treatment, marine engine compartments, and industrial oven construction use this material format because it can be wrapped, cut, or formed to complex shapes without delamination. The stitch-bonded construction also allows the mat to be handled dry and holds together during installation. For import trade, confirm whether Jotex supplies this as roll stock or cut pads, what the standard roll dimensions are, and whether the aluminum coating is plain, embossed, or perforated. Packaging for ocean freight typically involves polyethylene-wrapped rolls on pallets, but moisture protection during transit from Zhejiang Province ports should be verified.

Jotex Composite Materials Co, .Ltd. is located at No.1 Fenghuang Road, Ding Bridge Economic Zone, Haining, Zhejiang Province, postal code 314400, China. The company is classified as an imported-tier supplier with harbor trust status, which indicates a baseline verification level rather than premium assurance. The response rate is recorded at 0.00 percent with zero average response hours, meaning buyers should not expect rapid email or platform message replies and should plan to follow up directly by phone or through an agent in the Haining area.

The supplier profile does not state founding year, employee count, factory size, revenue, specific certifications, or named customers. What is known is the geographic concentration of Zhejiang Province in glass fiber and composite manufacturing, with Haining sitting within the broader Yangtze Delta industrial corridor. Buyers sourcing from Jotex should treat the engagement as requiring direct factory audit or third-party inspection, particularly for consistency of aluminum coating adhesion and density uniformity across rolls. No MOQ, price, lead time, or specific packaging details are present in the source data, so these must be negotiated directly.
