EKX-700 HF

EKX-700 HF by Advanced Composites (Mitsui Chemicals) is thermoplastic olefin (TPO) elastomer grade. It is designed for injection molding method. During processing of EKX-700 HF, holding pressure should be lower than boost pressure with a minimum amount of time to prevent over-packing of the part and screw should stop 1 to 2 seconds before mold open. Lower RPM of screw is preferred for mixing and uniform melt temperature. Injection speed should be slow to medium to prevent excessive shear on the material.
