    摘要: A device for measuring the elastic-viscous properties of objects, in particular objects made of an elastomer material such as rubber, has a measurement body movable in relation to a holder and having a measurement head that can be set on a test object, means for moving the measurement body back and forth and means for measuring the path of displacement of the measurement head and/or the force that acts on the measurement head during the reciprocating movement of the measurement body. In order to diversify the possible uses of the device and to simplify the measurement process, the measurement body is mounted in a freely movable housing with a passage for the measurement head and a bearing surface that can be set on the test object.

    摘要: A rubber mixture vulcanizable with sulphur, a tire tread manufactured from it and also tires with a vulcanized tread are proposed. The rubber mixture contains in each case 100 parts by weight of elastomers, 20 to 80 parts by weight of a copolymer of conjugated diene and vinyl aromatic compound with very low long chain branching manufactured by solution polymerization in a hydrocarbon solvent, 10 to 50 parts by weight of polybutadiene with very low long chain branching, 10 to 30 parts by weight of polyisoprene with a 3,4 bond content of 50 to 70% by weight and 30 to 100 parts by weight of silica as filler material. Through the special combination of the three elastomers with silica as a filler material one obtains an easily processable mixture which leads to vulcanized tire treads with improved grip on wet and dry surfaces.

    摘要: A caoutchouc mixture vulcanisable with sulphur, tire treads manufactured therefrom and also tires with these vulcanised tire treads are proposed. The caoutchouc mixture contains 30 to 100 parts by weight of isoprene-butadiene copolymer, 0 to 70 parts by weight of one or more further elastomers, 20 to 90 parts by weight of silica as a filler material, customary additives and also a vulcanisation system, with all parts by weight being related to 100 parts by weight of total elastomers. This caoutchouc mixture delivers tire treads with good resistance to abrasion and a low loss factor which is correlated with a low rolling resistance.
