Description

Prepreg PSB250 is designed for the production of composite parts or tools operated at temperatures up to 250°C. As a reinforcing material for a prepreg based on the bismaleimide resin PSB250, unidirectional belts and fabrics of various weave can be used. It shows the following features and properties:


  • Glass transition temperature 266°С
  • High strength and rigidity
  • Curing temperature 190°C, post-curing 230°C
  • Good stickiness
  • This material data has been provided by Matmatch.

    "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.
