This grade offers improved heat aging performance and excellent processability for injection molding of complex geometries with excellent surface aesthetics. It has low friction retention after heat aging without surface bleeding. It has been designed for corner molding and end caps of automotive extruded weather seals in TPV or in EPDM rubber.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eKey Features:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eLow friction injection molding grade\u003c\/li\u003e\n\u003cli\u003eSpecially formulated to replace thermoset EPDM rubber in automotive glass run channel (GRC) corner molding applications\u003c\/li\u003e\n\u003cli\u003eDesigned for shorter processing cycle time compared to thermoset EPDM rubber\u003c\/li\u003e\n\u003cli\u003eAdheres to vulcanized EPDM rubber and TPV\u003c\/li\u003e\n\u003cli\u003eBuilt-in low coefficient of friction properties\u003c\/li\u003e\n\u003cli\u003eGood flowability with excellent surface aspect\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eProcessing Form:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eInjection Molding\u003c\/li\u003e\n\u003cli\u003eMulti Injection Molding\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eProcessing Notes:\u003c\/b\u003e\u003cbr\u003eDesiccant drying for 3 hours at 80°C (180°F) is recommended. Santoprene TPV has a wide temperature processing window from 175 to 230°C (350 to 450°F). In order to obtain good bonding on an EPDM sponge profile, the injection speed should be fast (60–100 mm\/sec) and at a very high temperature in a warm mold. The injection pressure should be moderate and the holding pressure kept low to prevent profile deformation. The profile should be perfectly positioned in the mold without deformation to ensure maximum surface interaction with the melt. Cooling time should be longer than a typical TPV to initiate recrystallization at the contact interface. Santoprene® TPV is incompatible with acetal and PVC.\u003cbr\u003e\u003cbr\u003eSantoprene TPV has a relatively high melt viscosity at low shear rates. Viscosity decreases as the shear rate increases. Increasing temperature has little effect on TPV melt viscosity. Smaller gates and higher shear rates keep melt viscosity low and improve melt flow.
