Santoprene® TPV 241-80W236

Santoprene TPV 241-80W236 is a soft, colorable specialty thermoplastic vulcanizate (TPV) in the thermoplastic elastomer (TPE) family. It is designed for plumbing applications requiring contact with potable water. 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:

• NSF/ANSI 61 certified for drinking water system components
• Stabilized against copper and metal-catalyzed degradation
• Suitable for potable water plumbing applications
• High strength and flexibility with excellent elongation
• Recyclable within the manufacturing stream

Processing Form:

• Injection Molding
• Multi Injection Molding
• Extrusion
• Sheet Extrusion
• Blow Molding
• Injection Blow Molding
• Extrusion Blow Molding
• Small Tubing 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. As shear rate increases, viscosity decreases. Increasing temperature has little effect on melt viscosity. Smaller gates and higher shear rates keep melt viscosity low and improve melt flow. Please also refer to the injection molding guide.
