Ticona Engineering Polymers (Florence, Ky., USA; Kelsterbach, Germany) has announced the availability of new grades of Celstran+ PP long-fiber-reinforced thermoplastics (LFRT), designed to compete with SMA resins and PC/ABS blends that are commonly used by North American OEMs to mold automotive instrument panels, air duct panels and reinforcement components. Celstran+ PP GF20, GF30 and GF40 are customized engineering thermoplastics with long glass fibers chemically coupled to a base polypropylene (PP) resin. Ticona says comparison tests demonstrate that Celstran+ PP can outperform SMA and PC/ABS blends in heat aging, weight, part integration, foam adhesion, mechanical properties, injection molding processes and handling. Other features of the material are good creep resistance, good impact performance, strong notched impact strength — good tensile strength and elongation and high load bearing capacity. Ticona uses a pultrusion process to produce the material to achieve very even fiber coating with the base polymer and uniform fiber distributor in the matrix.
The plastic matrix in Celstran LFRT can be formulated with different polymer feedstocks, from polypropylene and nylon to polyurethane.
