Finite Fiber specializes in precision cut fiber polymer reinforcing materials.

Polyester Fibers


RFL treated precision cut polyester fibers deliver balanced properties
Polyester fibers characteristics are high density, tensile strength, modulus elongation at break, tear strength, abrasion resistance and moderate temperature sensitivity.

Description

High tensile, RFL treated engineered textile fiber. Constructed mult-filament plied and twisted fiber bundles designed and treated for enhanced matrix dispersion. Polyesters are semi-crystalline materials.

Characteristics

High tensile Polyester is characterized by its dimensional stability at high temperatures, high breaking strengths, excellent resistance to mildew and acids, with good aging, abrasion resistance, high tensile strength, resilience and resistance to stretching, as well as, superior compressibility.
