Gear weels with small modulus, cams, heavily loaded bearings and rollers, bearings and gears with small clearances, valve seats, snapfit assemblies, all kinds of dimensionally stable precision parts for machine construction, insulating components for electrical engineering, parts which operate continuously in water of 60-800C (ERTACETALC).
is very well suited for machining on automatic lathes and is particularly recommended for mechanical precision parts.
ERTACETAL C & H
Natural (white) / black
These are Metalon Marketing Services copolymer and homopolymer acetal grades. The acetal copolymer is more resistant against hydrolysis, strong alkalis and thermal-oxidative degradation than the acetal homopolymer. The latter, however, has higher mechanical strength, stiffness, hardness and creep resistance as well as a lower thermal expansion rate and often it also presents a better wear resistance.
ERTACETAL H-TF is a DELRIN® AF Blend, a combination of TEFLON® fibres evenly dispersed in a DELRIN acetal resin. Much of the strength that is inherent in ERTACETAL H is retained. Some properties change due to the addition of TEFLON fibre which is softer, less stiff and slipperier than virgin acetal resin.
Compared with ERTACETAL C&H, this material offers superior sliding properties. Bearings made of ERTACETAL H-TF show low friction, long wear and are essentially free of stick-slip behaviour.
