Acetal Homopolymer is used in high load mechanical applications. This Acetal resin is also used in plumbing and irrigation applications due to its excellent thread strength & ability to resist scale build-up.
Because of its machinability, the Acetal Homopolymer resin is used in prototyping of in vivo medical devices. It is also used in automotive applications.
Specific applications for Acetal Homopolymer resin include:
|Advantages||Acetal Homopolymer is a tough, resilient material that exhibits:
Compared to Acetal Copolymer resin, the Homopolymer offers higher tensile strength and impact resistance, as well as good stiffness and creep resistance. These properties allow for thinner and lighter part design, shorter molding cycles and the potential for cost reductions.
The disadvantages of Acetal Homopolymer resin include:
