SILASTIC™ LS-4960 Fluorosilicone Rubber
Developed to provide good handling in combination with high-temperature resistance and fluid resistance, this product is a 60 Durometer, Fluorosilicone Rubber Base specially designed for calendering and extrusion of turbocharger hoses. They also are suitable for molded parts requiring higher heat stability and/or improved fluid stability.
Fluorosilicone rubber bases with optimized performance for competing demands
Developed to provide good handling in combination with high-temperature resistance and fluid resistance, SILASTIC™ LS-49XX Series Fluorosilicone Rubber Bases are specially designed for calendering and extrusion of turbocharger hoses. They also are suitable for molded parts requiring higher heat stability and/or improved fluid stability.
SILASTIC™ LS-4940 Fluorosilicone Rubber Base and SILASTIC™ LS-4960 Fluorosilicone Rubber Base provide:
- Good balance of tensile, elongation and tear resistance
- Good heat stability with good tear retention
- Low compression set
- High fuel resistance
- Compound flexibility by application
- Reduced stickiness when unwrapping and mill-handling
