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-45A-BK-1-01 shows shrinkage values between 1.0– 2.5 %.
- 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.
Storage & Handling
- Purging
Purge thoroughly before and after use of this product (e.g. Polypropylene with MFI between 0.5 – 2.5).
- Drying Time
Material is not hygroscopic and drying is only necessary if material was stored under moisture.
