ABS is a homogenous material with high impact resistance and elasticity given by the butadiene component.A major advantage of the material is the working temperature range -40 to +60C at pressures up to 15bar. Pressure ratings for the thermoplastic pipe and fittings are always quoted for water at 20C and it is a fundamental principle in thermoplastic pipework that if the temperature increases then the working pressure must be reduced. With high impact strength and good abrasive resistance.
