Santoprene® TPV 691-65W175
Santoprene TPV 691-65W175 is a soft, colorable thermoplastic vulcanizate (TPV) in the thermoplastic elastomer (TPE) family. This material is designed for thin-wall, architectural glazing and sealing applications, offering excellent definition and dimensional stability. Santoprene TPV 691-65W175 is shear-dependent and can be processed on conventional thermoplastics equipment for extrusion or thermoforming. It is polyolefin based and recyclable within the manufacturing stream.
Key Features:
- Recommended for glazing and sealing applications
- Optimized for thin-wall extrusion with excellent definition (down to 0.33 mm radius)
- Minimal material build-up for long continuous run lengths
- Excellent ozone resistance
- Excellent flex fatigue resistance
- Recyclable within the manufacturing stream
Processing Form:
- Extrusion
- Sheet Extrusion
- Thermoforming
- Coextrusion
Processing Notes:
Desiccant 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) and is incompatible with acetal and PVC. Do not exceed 15% drawdown. High screw RPM (100–200) is recommended, and back pressure of 0.3–0.7 MPa may be used to ensure homogeneous melt and consistent shot size.
Applications:
Building & Construction, Consumer Goods
Hardness:
70A
Delivery Form:
Pellets
