Santoprene® TPV 271-87

Santoprene TPV 271-87 is a hard, colorable specialty thermoplastic vulcanizate (TPV) in the thermoplastic elastomer (TPE) family. It is designed for non-fatty food contact applications and offers high tensile strength and excellent elongation. This grade of Santoprene TPV is shear-dependent and can be processed on conventional thermoplastics equipment for injection molding, extrusion, blow molding, thermoforming or vacuum forming. It is polyolefin based and recyclable within the manufacturing stream.

Key Features:

• Suitable for non-fatty food contact applications (U.S. FDA restrictions may apply)
• NSF/ANSI 51 certified for food equipment materials
• UL listed for plastics components (U.S. and Canada)
• Excellent flex fatigue resistance
• Recyclable within the manufacturing stream

Processing Form:

• Injection Molding
• Multi Injection Molding
• Extrusion
• Sheet Extrusion
• Blow Molding
• Injection Blow Molding
• Extrusion Blow Molding
• Hose 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.

Santoprene TPV has a relatively high melt viscosity at low shear rates. Viscosity decreases as shear rate increases. Increasing temperature has little effect on viscosity. Smaller gates and higher shear rates keep melt viscosity low and improve flow. Please also refer to the injection molding guide.
