Adhesive Manufacture for Ebonite Bonding

As the choice of raw materials is steadily becoming a complex task with new polymers and compounding ingredients fighting for a place among the already established ones, critical evaluation is essential before their worth is assessed. 

It should be recognized that appreciable shifts in bonding strength are sometimes made possible by special compounding variations for instance, the heat resistance of NR vulcanizates may be improved considerably by variation of the vulcanizing system. The normal sulphur vulcanization system is capable of many variants, which will govern the chemical nature of the sulphur cross link, i.e., whether it is essentially a more, di, or poly-sulphide type. The nature of sulphur cross link can have considerable influence on the bond strength and the heat-resistance of vulcanizate
