Santoprene® TPV 8211-85M350

Santoprene TPV 8211-85M350 is hard, colorable, thermoplastic vulcanizate (TPV) in the thermoplastic elastomer (TPE) family. This material is developed to be used as a skin for molding onto rigid polypropylene substrates in automotive interior applications such as door panels and center consoles. For these applications, this grade combines low gloss, high scratch and mar resistance, low emissions (fogging, odor) and comfort touch. This grade of Santoprene TPV is shear-dependent and can be processed on conventional mono- and multi-component injection molding machines. It is polyolefin based, adheres to and is compatible with polypropylene, and is recyclable within the manufacturing stream..

Key Features:

Non-hygroscopic product, requires little to no drying before processing.
Neutral, easy coloring formulation.
Designed for applications requiring high-flow materials.
Low emissions.
Cost effective alternative to soft touch paint over PP substrate.

Processing Form:

Injection Molding
Multi Injection Molding

Processing Notes:

If desired, desiccant drying for 3 hours at 80°C (180°F) can be performed. 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.

Applications:

Automotive, Consumer goods

Hardness:

Delivery Form:
