HEAT-RESISTANT ELASTOMERS AUTOMOTIVE MATERIALS

The synthetic rubber industry is furnishing new or modified polymers to the automotive industry that meet or exceed required performance properties. Since stricter emission standards requiring additions and modifications to the internal combustion engine have resulted in higher underhood and underbody temperatures, heat resistance and oil and solvent resistance under the hood (engine compartment, drivetrain, and fuel and emission systems) have become increasingly important. Most of the new elastomers and improved polymers are directed toward improvements in these two critical areas while still maintaining tensile strength, abrasion resistance, low-temperature flexibility, and elongation. Among specialty elastomers finding increased automotive applications are fluoroelastomers (3M's Fluorel 2460), thermoplastics (DuPont's Hytrel, Shell's Kraton G-7900, Prolastic 221), and silicone rubber. New polymers developed for the auto industry include ethylene/acrylic elastomers (DuPont's Vamac).
