Storage Life of Fully Compounded Rubber Stocks. Part 2: 12 Months' Storage Testing. Part 3: Subsequent Ageing Behaviour

Abstract

Ten fully compounded rubber stocks representative of natural and synthetic rubber mixes have been stored for periods up to twelve months and their processing and cure characteristics determined. Results show that after storage at room temperature, satisfactory mouldings may be produced from most of the stored stocks, both by injection and compression moulding, having similar properties to those produced from unstored materials. Ten fully compounded stocks, five of natural and five of synthetic rubber, have been stored at room temperature and 40C for various times and vulcanisates prepared from them by compression and injection moulding have been subsequently aged at 80C for up to 16 weeks. The general ageing characteristics of the vulcanisates prepared from the stocks are not altered to any significant degree by storage, provided that each stock is given its optimum cure.
