Crude rubber must be cured, or crosslinked, to make it a practical engineering material. The rubber industry has developed a powerful armoury of rubber curing agent, including sulphur sources, peroxides, metal oxides, amines & phenolic resins. Ethylene thiourea, one of the most popular curing agent for chloroprene rubber, is subject to increasing suspicion as a carcinogen and teratogen. A new generation of curing agent based on carbon rather than sulphur bonds is undergoing trials and investigations have recently been reported on the functionalisation of silica filler with curing agents. Attempts are also being made to develop controllably reversible curing systems, in order to aid rubber recycling. These chemical additive is suitable for creating network bonds with c-cl groups of the elastomer, without adding catalysts or stabilisers, either at the crosslinking temperature or at room temperature. The ionic bonds formed this way had an effect on the mechanical properties of the vulcanisates, in particular the chemical compound increased the ability to dissipate critical stresses and improved the adhesion of chlorosulphonated pe to steel.
