PREPERM helps to design more sustainable products. This is a challenge for material performance. The advantages of PREPERM materials relate to more efficient data transfer (antennas, mobile base stations, satellite communication), better sensitivity (GPS, radars, radomes) and longer battery life (mobile and IoT devices).

Short glass fiber Injection molded part Long glass fiber CAPABILITIES TO BUILD BETTER Long fiber reinforced composite materials incorporate longer filaments of fiber reinforcement to increase mechanical properties and structural capabilities to higher levels than short fiber formulations. DESIGN & DEPLOY WITH CONFIDENCE Transitioning from traditional materials to long fiber composites requires an integrated approach that includes material formulation, component design, and forming process. Complēt™ LCF Long carbon fiber reinforced materials have higher rigidity/modulus, higher strength, lighter weight, and more marketability potential than glass fiber, making it the ideal fiber reinforcement for metal replacement.

Generally, SEBS materials have higher shrinkage and are more anisotropic than SBS materials. Softer SEBS materials (below 30 Shore A) will shrink more than harder 6 materials. The material residence time for SEBS formulations should be no more than 10 minutes.
