Tecaform™ Acetal Copolymer
TECAFORM™ is commonly used as bushings, rollers, wear strips and other applications requiring a combination of strength, low moisture absorption, chemical resistance and dimensional stability.
TECAFORM™ is a semi-crystalline thermoplastic offering high strength, stiffness and toughness. TECAFORM™ is resistant to hot water, hydrocarbons and solvents, and it possesses good bearing and wear properties. It is available in natural and black grades. TECAFORM™ is commonly used as bushings, rollers, wear strips and other applications requiring a combination of strength, low moisture absorption, chemical resistance and dimensional stability.
- No centerline porosity
- Low moisture absorption
- Excellent machinability
- Good combination of mechanical properties
- Chemical resistance to fuels and solvents
- TECAFORM™ is resistant to aqueous solutions with pH values ranging from 4 to 14.
- Good wear and abrasion properties
- Natural grade is manufactured from resins that are FDA, USDA, NSF and 3A Sanitary compliant
- Good dimensional stability
- Good property retention at elevated temperatures
- Black Grades are also manufactured from resin that is FDA compliant
TECAFORM™ is used in a wide variety of industrial applications requiring good strength and toughness, dimensional stability, wear resistance and the ability to operate in a wet environment with little absorption. Material handling, machinery and fluid handling are some of the common industries utilizing TECAFORM™ ’s combination of properties. Typical applications are gears, wear strips, bushings, pump parts, fittings and rollers.
