High-Performance Milled Fiber

Product catalog summary

Overview: Thermafiber® FRF 114 & FRF 514 are high-performance milled fibers designed for economical reinforcement and filler applications. They offer excellent fire and heat resistance, abrasion, and friction properties, and are used in products like gaskets, paints, caulks, mastics, and adhesives.

Specifications:

FRF 114 has a non-fibrous content of less than 5% and a poured density of 7.5 - 9.5 pcf.
FRF 514 has a non-fibrous content of less than 20% and a poured density of 8.2 - 10.5 pcf.
Both products have a flame spread of 0 and smoke developed rating of 5.

Applications:

Brake shoes and clutches for wear resistance and abrasion.
Cement coatings for reinforcement and filler.
Plastics for shape retention.
Auto gaskets for heat resistance.
Roofing asphalt for wear resistance and resilience.
Paints for viscosity modification.
