Ertacetal® C is Quadrant’s copolymer acetal grade. Next to the standard natural and black grades, there is also a series of special colours available all showing an FDA food contact compliant composition. The acetal copolymer is more resistant against hydrolysis, strong alkalis and thermal oxidative degradation than the acetal homopolymer.
MAIN CHARACTERISTICS
- High mechanical strength, stiffness and hardness
- High modulus of elasticity
- Good resistance to creep
- High impact resistance even at low temperatures
- Excellent dimensional stability
- Good slip properties and wear resistance
- Easy machining (better than polyamide)
- Low moisture absorption
- High resistance to chemicals
- Physiologically inert
ApPLICATIONS
- Dimensionally stable precision parts
- Small module sprockets
- Couplings, gloves, valve elements
- Bushings
- All types of parts where better finishing and dimensional stability are required
- Heavy duty bearings and rollers
- Bearings and gears with small gaps
- Components for electrical insulation
