At Trident we offer both homopolymer and copolymer grades of Acetal rod, sheet and tube. Ertacetal®C (Acetron® GP) is porosity-free and offered as our standard general purpose grade. For slightly higher mechanical properties, we offer as a non-standard, homopolymer Ertacetal® H (Acetal) (Delrin®) products.
Ertacetal® H (Delrin®), homopolymer acetal rod, sheet and tube offer slightly higher mechanical properties than Ertacetal® C Acetal, but may contain a low-density centre, especially in larger cross-sections. Ertacetal® C (Copolymer) also offers better chemical resistance than homopolymer acetal. Ertacetal® H is suitable for small diameter, thin-walled bushings that benefit from the additional strength and rigidity of homopolymer acetal.
It is the preferred acetal for food contact and medical applications. Acetal is a semi-crystalline material with high strength, a low coefficient of friction and good wear properties especially in wet environments (resistance to hydrolysis).
Advantages of Acetal Rod, Acetal Sheet and Acetal Tube:
Acetal’s great machinability together with its dimensional stability, mechanical strength, zero moisture absorption and good load-bearing properties make it ideal for close-tolerance parts.
Key Features of Acetal Rod, Acetal Sheet and Acetal Tube:
- High hardness and stiffness
- Very high mechanical properties
- Excellent creep resistance and dimensional stability
- Excellent dielectrical properties
- Low co-efficient of friction
Applications of Acetal Machined Parts:
- Precision gears
- Bearings with close tolerances
- Electrical engineering insulators
- Compact bearing assembly
- Snap fit assemblies
- Parts which operate in water between 60 to 90;C
