Ethylene/α-olefin Copolymers for Automotive Interiors 2000-01-0747
Ethylene/alpha-olefin copolymer elastomers based on constrained geometry catalysts exhibit a number of physical properties that make them extremely useful for automotive interior applications. Ethylene/1-octene (EO) copolymer polyolefin elastomers exhibit an optimum combination of properties.
Due to the low level of unsaturation in these polymers, they exhibit outstanding heat and UV aging resistance. Their molecular structures enables these polymers to exhibit low glass transition temperatures (Tg). Thus, compositions containing these polymers exhibit very good low temperature impact properties. Furthermore, these products impart inherent flexibility and soft touch to compositions and eliminate the need for plasticizers. These elastomers can be compounded to produce flexible TPO compositions suitable for automotive interior applications
