Mixtures of bitumen and polymer compositions

Use of propylene copolymers with up to 50 wt % of units derived from at least one linear or branched alpha-olefin having from 2 to 10 carbon atoms other than propylene for producing injection-molded coating on a metallic pipe.

Propylene polymers for injection molding applications

A process for effecting a coupling between a plastic material and a metal surface comprising the steps of applying a powder of an adhesive polymer composition to the metal surface; then overmoulding the metal surface with a plastic material by injection moulding; and finally applying heat to the metal surface.

Coupling metal parts with a plastic material

Polypropylene composition comprising by weight (A) 60-90% of at least one heavy mineral filler having a specific weight greater than or equal to 3; (B) 0.1-4% of a filler compatibilizer; and (C) 10-40% of a heterophasic polyolefin composition containing rubber. Said composition has an MIL ranging from 0.5 to 10 g/10 min, elongation at break greater than 100 to 800%, and flexural modulus ranging from 100 to less than 3000 MPa.
