Polymer, loaded with reinforced filler, is introduced into the mold assembly via the input gate (116).

The invention concerns a novel method for preparing precipitated silica used as reinforcing filler for elastomers.

The invention concerns a tyre tread including for the major part black carbon as reinforcing filler.

The thus prepared silica precipitates are particularly well adapted for use as reinforcing elastomer filler.

The biopolymeric materials most preferably include reinforcing media, such as biocompatible fibrous or particulate materials.

Thermoplastic compositions comprising polyamide, polyimide, an organo phosphorus compound and an optional reinforcing filler are described.

It may further comprise (E) a reinforcing filler, (F) a crystallization accelerator, and (G) a polyfunctional compound.

This solid foam, inherently, i.e. without any reinforcing agent or filler, has a good dimensional stability.

The rubber composition may have activated carbon as the primary reinforcing filler at a loading of from 25 to 250 phr.

Said compounds are useful as white filler-elastomer coupling agents in diene rubber compositions comprising, as reinforcing filler, a white filler such as a siliceous material.

Said compounds can be used as white filler/elastomer coupling agents in diene rubber compositions comprising, by way of reinforcing filler, a white filler such as a siliceous material.

Said compounds can be used as white charge-elastomer coupling agents in dienic rubber compositions comprising a white charge such as a siliceous material as a reinforcing charge.

Compositions comprising graphene sheets. at least one reinforcing agent, and at least one rubber.

Typically, the content of coupling agent represents from 0.5% to 15% by weight relative to the amount of inorganic filler.

Polymer is positioned in the mold assembly with the reinforcing filler being substantially parallel and aligned with the flow path.
