DURABILITY OF OLEFINIC THERMOPLASTIC ELASTOMERS 760728

Data is presented showing that thermoplastic elastomers have good weathering properties, are serviceable over a broad temperature range, and resist a wide selection of chemicals.A statistically designed experiment for a family of olefinic thermoelastics covering a wide range of processing, physical and mechanical properties is reported and results confirmed with compositions derived from the design predictor equations.All compositions within the design parameters pass selected critical automotive painting specifications suggesting that extensive and costly materials qualification procedures currently required for even minor changes can be streamlined considerably to facilitate their early commercial introduction to a particular application area.
