A process for manufacturing a composite automobile part by overmoulding, over at least one surface of an insert (1) comprising a first plastic material, a layer of a second thermoplastic material, comprises the following successive steps: a) a step of positioning said insert (1) in a mould, and b) a step of moulding said second thermoplastic material over said insert. At least one of said first and second materials comprises an additive, said additive comprising a polymer to which carboxylic anhydride monomers are grafted. Said first and second materials are respectively based on polyamide and based on polypropylene, or vice versa and said second material comprises talc as mineral filler.

Process for overmoulding over a plastic insert and automobile part obtained by this process

A granulation method that can be used to obtain a polymer from 'post-consumer' materials, and a motor vehicle part made from polymers produced by recycling used polymers.

Method for granulating polymers and product produced by this method

The method for manufacturing a composition consists in bringing into contact a product containing mostly polypropylene having a controlled fluidity less than 10 g/10 min with highly fluid polypropylene and a polymer grafted with maleic anhydride.

Method for manufacturing a polypropylene composition with controlled fluidity

The invention relates to a recycling method for obtaining a polymer from 'post-consumer' materials, and to a material and a part consisting of polymers obtained from the recycling of used polymers.

Method for recycling polymers and product produced from said method

The invention relates to a plastics material part for a motor vehicle, the part comprising polypropylene filled with non-recycled glass fibers. The part further comprises 15% to 25% polypropylene filled with recycled glass fibers.
