Ordinary fibers are often helpless in the face of fire, but HS flame-retardant fiber, like the “always calm hero,” remains resilient in the face of intense heat. If you’re struggling to improve the safety of your products, look no further; this high-performance flame-retardant polyester fiber is exactly what you’re looking for!

What is HS flame-retardant fiber? Not all fibers qualify as flame-retardant.

HS Flame Retardant Fiber is a polyester-based flame-retardant staple fiber developed by Weihigh based on market demand and international safety standards. Its core advantages lie in its self-extinguishing properties, zero droplets, and low smoke output even in the presence of open flames, reducing fire risks at the source.

More importantly, it’s not a “pseudo-flame retardant” achieved through surface treatment. Instead, flame retardants are incorporated into the raw materials from the beginning, resulting in more durable and stable fire resistance, even after numerous washes!

Selected raw materials create high-quality safety fibers.

We understand that recycled resources don’t necessarily equate to low quality. Weihigh uses high-quality, environmentally friendly recycled PET bottle flakes as its base raw material, supplemented with imported flame retardant additives. This ensures that each HS flame-retardant fiber balances environmental friendliness, strength, and flame-retardant properties.

Environmental Standards: Passed multiple international certifications, including OEKO-TEX and GRS.

Flame Ratings: Meets UL94-V0, B1/M1, and other levels.

Stable Performance: High-temperature resistance, low shrinkage, and compatibility with various textile processes.

We also offer customized services with varying denier, length, and fiber crimp to meet diverse customer needs for nonwoven fabrics, automotive interiors, building insulation, and other applications.

Why Choose HS Flame-Retardant Fiber? In a nutshell: Safety Starts with the Fiber!
