Glossary » Materials » Polymers » Polyacetal » 1.5% PTFE Filled
1.5% PTFE Filled Acetal is a subcategory of Polyacetal. The additative is added by weight during the manufacturing process.
Polyacetal, also known as Acetal, is a thermoplastic. Common trade names are Delrin and Ultraform. homopolymer It is a lubricious, strong, and resistant to creep and fatigue. It has good dimensional stability and relatively high abrasion and chemical resistance. Acetal is commonly used in quality toy parts, handles, knobs, and bearing parts. Delrin is approved by FDA for use in the food industry. Acetal resins were commonly used in the plumbing industry. However, they are sensitive to chlorine which leads to cracks in acetal plumbing fittings. The widespread failure of acetal moldings in potable and hot water supplies resulted in one of the largest class actions in the USA when acetal plumbing fittings cracked and caused floods of many homes in many states.
