Description

Hytrel® by DuPont™ is a family of high performance thermoplastic elastomers that incorporates the most useful characteristics and material properties of elastomers and plastics, including excellent toughness, creep and impact resistance, resilience and fatigue strength. Hytrel® HTR8808 is a high-temperature thermoplastic polyester elastomer (TPEE) grade that shows outstanding balance of heat resistance and stiffness, high flexibility and pressure resistance. It is convenient for processing by blow moulding and is recommended for pressurized air ducts for turbo gasoline engines. HTR8808 is cyclically flexible in different directions and is highly durable, which makes an important ingredient in components in the automotive industry.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
