Two-component Injection Moulding. New hard-soft combinations of POM and TPU (TPE) are being produced by injection moulding. For this application, POM (Hostaform) copolymer grades with different impact modification and TPU (Elastollan) grades with varying degrees of hardness are being combined. The bond strengths of the different hard-soft combinations, as determined in a standardised tensile test, are evaluated and discussed. The results are compared with those for a hard-soft combination with SEBS as the TPE.
