Materials: Unique PC/ABS and Polyester TPE Compounds Bridge Gaps
Nova Polymers’ Nova TPEE polyester elastomer offers 15-20% cost saving over comparable materials.
Two reportedly unique compounds have been developed by Nova Polymers Inc., Evansville, Indiana. NC8020TC is a PC/ABS said to be an improved version to the company’s existing PC/ABS product line specifically with regard to chemical resistance. The company is testing the material which is positioned to bridge the gap between PC/PBT and standard PC/ABS. It is available in custom colors.
Nova TPEE polyester elastomer, is a new TPE compound that is a blend of co-polyester resins with an acrylic modifier and a proprietary blend of additives, which is said to all the company to use lower-cost feedstocks, offering a 15-20% cost savings over comparable materials. This TPE compound boasts UV resistance and flame retardance for applications such as air dams, front-end fascias and other automotive applications that require maximum ductility coupled with excellent mechanical properties. In many cases, the properties can be adjusted to meet specific customer requirements.
Conventional molding techniques are not effective with high-temperature materials. Molders need to be aware of certain conditions and parameters to handle problems sometimes posed by high-heat injection molding.
Advances in materials, feedblock/die technologies, and winding can help processors develop more sophisticated cast-stretch products.
One of the first applications for blow molded HDPE bottles was the replacement of glass for bleach packaging.
