Some info on Acetal Plastic
ACETAL is a thermoplastic material and is among the strongest and stiffest of all thermoplastics. It has excellent tensile strength, thermal properties, hardness and chemical resistance. The normal short-term temperature use range for Acetal is -40 to 270°F (-40 to 132°C ). Acetal's properties remain consistent across a wide range of temperature and humidity. It also has excellent structural memory after being subjected to repeated loading.
