EP-S 31 HP
EP-S 31 HP is a heterophasic polypropylene copolymer with an exceptional mechanical properties balance. The product has been speciﬁcally designed for the extrusion of conduit pipe, corrugated pipe and other extrusion applications.
In comparison with standard polypropylene copolymers with the same ﬂuidity. EP-S 31 HP offers some distinct advantages:
- higher stiffness.
- superior impact resistance both at room temperature and at low temperatures.
- excellent creep and deformation resistance
- very high dimensional stability.
Because of these outstanding mechanical properties.
EP-S 31 HP can be used in demanding applications such as conduit pipes and ﬁttings for electrical distribution and cable protection.
Corrugated pipes for automobile and machine construction, plane- and shipbuilding and for domestic appliances are another major application.
EP-S 31 HP can also be used for the extrusion blow moulding of bottles and containers and for the extrusion of corrugated board.
