Advantages

  • Resistance to creep and fatigue
  • Rigidity and resilience
  • Resistance to solvents

Limitations

  • High specific gravity
  • Anisotropic shrinkage
  • Processing difficulties

Overview

Acetals are rigid, creep resistant and strong. They possess low coefficients of friction. They remain stable in high temperature service and offer exceptional resistance to hot water environments.

They are virtually unaffected by strong bases but are attacked by strong mineral acids.

A 40% glass reinforced acetal has a flexural modulus of 1.6 psi x 10E-6 (11024 MPa) and 330 degrees F (166 degrees C) heat deflection temperature.
