New Standard Helps Classify Rubberlike Materials
A new standard from ASTM International’s plastics committee (D20) includes a classification system for a type of rubberlike material used in everything from clothing to car parts.
According to Huub Omloo, a senior standardization manager at Netherlands-based DSM Engineering Plastics, these materials – known as thermoplastic copolyester molding and extrusion materials or TPC – are rubber-like materials combining flexibility, high-temperature resistance and strength in a unique way.
Soft forms of TPC are used in products like fitness clothing while firmer forms can be used for things like air ducts.
The standard (D8156) also allows for the use of recycled copolyester elastomers if classification requirements are met.
Raw plastic material manufacturers, buyers, and testers will find this standard most useful.
