产品描述
Santoprene™ 591-65W175 is a soft, black thermoplastic vulcanizate (TPV) in the thermoplastic elastomer (TPE) family. This material is designed for thin wall, architectural glazing and sealing applications in industry and consumer segments. This grade of Santoprene™ TPV is shear-dependent and can be processed on conventional thermoplastics equipment for extrusion, thermoforming. It is polyolefin based and completely recyclable.
Key Features
• Recommended for glazing and sealing applications in industry and consumer segments.
• Excellent resistance to compression set.
• Designed for extruding thin sections with excellent definition (down to 0.33 mm [0.013"] radius). Long runs with minimal build-up of material on screen packs or narrow sections die sections.
