Import Flame Retardant Heat Shrinkable Tube — Buy in Bulk from Supplier in United States

Huawoer Heat-Shrinkable Material Co., Ltd supplies flame retardant heat shrinkable tubing designed for electrical insulation and mechanical protection in demanding environments. The product shrinks at 120°C with a 3:1 shrink ratio and is available in diameters ranging from 3.2mm to 25.4mm before shrinking. Wall thickness varies from 0.5mm to 1.2mm depending on the nominal size, and the tubing meets UL 224 standards for flame resistance and electrical insulation. The material is formulated to resist cracking under thermal cycling and maintains flexibility after shrinking.

The tubing is made from modified polyolefin compounds with added flame retardant agents such as antimony trioxide and halogen-free additives, aligning with RoHS directives. It exhibits resistance to solvents, oils, and chemicals commonly found in industrial and automotive settings. Typical color options include black, red, blue, and yellow, with custom colors available on request. The base material is not PVC, avoiding chlorine-based emissions during thermal stress, which distinguishes it from older-generation tubing.

This tubing is widely used for solder joint insulation, wire bundling, corrosion protection of metal conduits, and antenna shielding in aerospace, automotive, and telecommunications sectors. Buyers include OEMs, industrial maintenance contractors, and wire harness manufacturers sourcing for compliance with military and industrial safety standards. Packaging is typically on spools or in bulk boxes, with minimum order quantities negotiable for standard sizes. Sample orders are accepted, and delivery is available globally with secure payment terms.

Huawoer Heat-Shrinkable Material Co., Ltd operates from Huizhou City, with manufacturing based in Building A of the TCL Yunshan Industry Zone. The company identifies as a professional manufacturer with over ten years of experience in heat shrink tubing, serving global clients in automotive, electronics, and industrial sectors. The supplier has no publicly listed certifications, certifications, or audited quality systems beyond its claim of compliance with RoHS and UL standards, which are referenced from product performance, not documentation.

There is no verified data on company size, revenue, or export volume. The supplier accepts sample orders and offers customization in size, color, and packaging, indicating responsiveness to niche buyer needs. Response rate and average response time are not tracked in the listing, suggesting limited real-time engagement capability. Buyers should verify all technical claims directly with the supplier before placing bulk orders.
