Description

Thermoplastic block copolymer has high wear resistance, flexibility over a wide range of temperatures, and high elasticity over the entire hardness range. Resistance to weathering and high-energy radiation. The key features are:


  • Durable: High wear resistance and resistant to oils and some solvents.
  • Flexible: Functions over a high range of temperatures.
  • Versatile: Alter hardness, strength, rigidity, elasticity and cold-flexibility.
  • This material data has been provided by M-Base.

    "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.
