High Strength Mechanical Gears

Gears are the obvious and well-known application area for Delrin® homopolymer acetal; the acetal brand has truly excelled in this area. Delrin® was the first acetal type to replace metal machined gears with its advanced mechanical properties. Engineers need a high tensile strength polymer because the fine detail of gear teeth with high loads requires the highest mechanical strength. Delrin® fulfills this requirement as well as having precise dimensional accuracy due to its uniform crystalline structure.

Delrin® acetal gears are now the first choice for many moving parts that you find in vacuum cleaners, coffee machines, office printers, electric toothbrushes, power tools and more.

Compared to acetal copolymer, Delrin® acetal homopolymer offers higher tensile strength, stiffness, creep and fatigue resistance, and significantly higher impact resistance. The extra mechanical properties of Delrin® allow for parts to be made thinner and smaller, whilst delivering the same performance of a thicker, less compact copolymer acetal moulding.
