Shrinkage Properties

Unisoft TPE™grades are anisotropic materials. Their shrinkage properties are higher in the flow direction, and the shrinkage in the cross-flow direction is less. Unisoft TPE™ ST-50A-CL-1-01 shows shrinkage values between 0.8 – 2.7 %.

Rheological Properties

Actual rheological data of Unisoft TPE™ materials are shear dependence. Viscosity will decrease at higher shear rates, and should be considered during injection molding design and setup of processing conditions.
