Unital® Acetal (polyoxy-methylene) offers design engineers a superior blend of strength, stiffness, lubricity, and dimensional stability. These properties, along with inherent machining ease, have made Unital® one of the most widely used engineering grade thermoplastics. Unital® LF-13 utilizes a powdered PTFE at a 13% loading and is compliant with both FDA and USDA regulations at a cost that is up to 33% less than other filled acetal products, making it the workhorse of the enhanced wear acetal product family.
