Santoprene® TPV 101-45W255

Santoprene TPV 101-45W255 is a soft, black thermoplastic vulcanizate (TPV) in the thermoplastic elastomer (TPE) family. This material is designed for use in residential washing machine and dishwasher applications and contains a stabilization system for protection against copper and other metal-catalyzed degradation. This grade of Santoprene TPV is shear-dependent and can be processed on conventional thermoplastics equipment for injection molding or extrusion. It is polyolefin based and recyclable within the manufacturing stream.

Key Features:

• UL listed: file #QMFZ2.E80017 and #QMFZ8.E80017 for plastics components
• Stabilized against copper and metal-catalyzed degradation
• Property retention in presence of dishwasher and washing machine detergents
• Suitable for injection molding and extrusion
• Recyclable within the manufacturing stream

Processing Form:

• Injection Molding
• Multi Injection Molding
• Extrusion
• Sheet Extrusion
• 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 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. Please also refer to the injection molding guide.
