Ultra-Low-Temperature Toughened Injection Molded Parts

Toughened materials and injection molding solutions for parts that become brittle, lose impact strength or crack at low temperature — keeping excellent performance even in severe environments.

Low temperature impact
High toughness
Crack resistant
Stable dimensions
01 Common Problems

In low temperature environments plastic parts easily become brittle and crack

In winter or in low temperature environments, ordinary nylon and engineering plastics can lose impact strength, become brittle and crack, which shortens the service life and reduces reliability of the product.

  • 1Do parts become brittle and crack at low temperature?
  • 2Is the low temperature impact strength below the requirement?
  • 3Do parts fail easily in outdoor use?
  • 4Is dimensional stability poor and assembly affected?
  • 5How can the low temperature toughness of the material be improved?
