| Processing Information: Injection Molding (preferable standard 2-component injection molding machine to get adhesion to substrate)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 is stored under moisture.Shrinkage Properties: This material is anisotropic. The shrinkage properties are higher in the flow direction, and the shrinkage in the cross-flow direction is less. Typical shrinkage properties values are between 0.8 - 2.2%Rheoligical Properties: This material is shear dependent. Viscosity will decrease at higher shear rates, and should be considered during injection molding design and setup of processing conditions.FDA Compliance: Softflex 7088 is based on Styrenic-Ethylene/Bthylene block-copolymers as described by FDA, article 21. A valid Code of Federal Regulations (CFR) is described in paragraph 177.1810 and/or paragraph 176.170, categories I, II, IV-B, VI, VII-B, VIII in panel 1. |
