摘要： Rubber compound for preparing pneumatic tyre parts comprising a cross-linkable unsaturated chain polymer base, a filler, a vulcanization system and one or more antioxidant agents. The antioxidant agents comprise functionalized lignin with –OR groups, where R is a terpene group with a total number of carbon atoms of between 6 and 16. The –OR groups deriving from the functionalization of 10 to 60% of the lignin phenolic hydroxyl groups.

摘要： Described herein are systems and methods for delivering catalyst to a reaction vessel. The methods include the use of a positive displacement reciprocating piston system having a catalyst delivery housing that contains a piston system. The piston system includes a top section, a bottom section, and a catalyst holding space between the top and bottom section such that the piston system is movable between a first and a second position to inject catalyst from the catalyst holding space into the reaction vessel when the piston system is in the second position and fill the catalyst holding space with catalyst from a catalyst feed supply when the piston system is in the first position.

摘要： The present invention relates to a tyre having a sealant layer in order to prevent the leakage of air (or gas) in case of a puncture, and a system for the detection of the puncture for subsequent warning of the driver. The puncture detection system in turn comprises a sensor layer constructed in such a way as to simplify the operation of removing the sealant layer during the disposal of the tyre.
