NYLON 6 - 6/6
Nylon will absorb 2.5% of its own body weight to achive its equilibrium point. The difference between a "wet" and "dry" Nylon is subtantial for property testing specification that are made in a "wet" equilibrium condition.
- High mechanical strength
- Great rigidity
- Great stability to heat
- Excellent toughness even at subzero temperatures
- Good fire behaviour
- Good resistance to oils, grease and solvents
- Dyes very easily
ACETAL
- High rigidity
- High mechanical strenght
- Good elasticity
- Excellent abrasion resistance
- Good resistance to oils, grease and solvents
- Low water absorption
POLYPROPYLENE
- Excellent chemical resistant including acids
- Ideal combination of medium strength and creep strength
- Low water absorption
POLYESTER
- High rigidity and hardness
- Low tendecy to creep
- Short term heat distortion temperature
- Good abrasion resistance
- Good insulation properties
- Minimal water absorption
- Good chemical resistance
- Good impact strength at low temperatures
