- 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-35A-NT-1-01 shows shrinkage values between 1.0– 3.2 %.
- 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.
