A composite structural part in at least three sections, two having a free end, strengthening and thermoplastic elements at the junction points, and with at least two sections having terminal bulges is new. A composite structural part (CSP) is in at least t...

The invention relates to rubber compounds containing at least one NSBR terpolymer and at least one polar synthetic plasticizer, a method for their production, and the use for the manufacture of rubber molded articles of all kinds.

A rubber mixture based on a double bond-containing rubber (A) (plus fillers and rubber additives as required), also contains 10-150 wt% (based on A) of particles of polybutadiene rubber (B) with a glass transition point (Tg) below -60 degrees C.

Rubber mixture comprises 10-800 pts. wt. filler, 100 pts. wt. of a rubber prepared from 0-50 wt.% vinyl aromatic monomers, 45-99.95 wt.% diolefins with 0-80 wt.% 1,2-bound diolefins and containing 0.05-5 wt.% hydroxyl and /or carboxyl groups or their salts...

Rubber mixture comprises 100 pts. wt. of a rubber containing 0.1-3 wt.% hydroxyl and /or carboxyl groups and 5-500 pts. wt. hydrophobicized, oxidic or silicate filler and optionally other rubbers, aids and crosslinkers.
