Rockforce® RF825-Roxul®1000

Technical DataSheet | Supplied by Lapinus Fibres

Aminosilane surface treated engineered mineral fiber. It exhibits excellent controlled dimensional stability, CLTE (coefficient of linear thermal expansion), high HDT (heat deflection temperature), improved scratch resistance, surface quality, low abrasion (less machine wear compared to glass fibers), reduced tendency for warpage and good weld line strength. Offers a set of mechanical properties at unique price/performance balance. Suitable for reinforcement in thermoplastics. In polar matrixes like PA, ABS, PC or PBT the interaction between aminosilane treated fibre and the matrix is normally sufficient enough to obtain the desired reinforcing properties.
