Our FILLTECK™ fibers enhance the dimensional stability of the rubber by forming a three-dimensional matrix inside the product, while also providing
strength and structure throughout the processing phase of the rubber. FILLTECK™ filled rubbers can show improved elastic behavior and strength and
stiffness. Milled FILLTECK™ fibers can reinforce both uncured (green) and cured rubber very effectively. In "green" rubber, properties such as
yield strength, modulus and Mooney viscosity are all improved by the addition of FILLTECK™ fibers. In cured rubbers, initial modulus, compressive
strength, bending stiffness and tear resistance are all enhanced. FILLTECK™ fibers are naturally hygroscopic; absorbing free moisture thereby improving
the vulcanization process. FILLTECK™ manufactured fibers are high-surface-area cotton and flock fiber reinforcements for rubber and plastic compounding.
The FILLTECK™ brand of fiber is known for its high strength to weight ratio, high modulus, and thermal stability. Rubber chemists who evaluated
high-surface-area cotton flock fiber reinforcements found them highly effective in rubber reinforcement, creating an effective mechanical coupling between
the rubber and fiber.
FILLTECK™ fibers provide improved quality and consistency in finished product while reducing shrinkage. Milled FILLTECK™ fibers including cotton,
nylon and polyester are found in applications such as: power transmission belts, 'V' belts, timing belts, conveyor belts, hoses, friction parts, rubber
roll covers, seals and numerous other automotive uses. Precision Cut fibers of 1 mm - 6 mm in length have been used in these applications.
