The rubber is suitable for isolation in vulcanization of radial tire capsules and bias tire capsules, has excellent isolation effect, and does not cause quality problems such as rubber shortage, joint cracking, delamination, spot formation and the like. Has good slippage and isolation between the bladder and the green tire. Generally, the product is divided into three types of 2 times of water adding, 1 time of water adding and no water adding.
At present, most separant manufacturers adopt an intermittent production mode for production, namely raw materials such as silicone oil and an active agent are added into a reaction kettle, reaction is carried out under certain conditions, when the reaction is finished, the raw materials are conveyed to a grinding machine for grinding, then stirred by a stirring tank to obtain a reaction stock solution, and the stock solution is directly conveyed into a finished product tank for storage, or diluted by adding water into the stock solution according to the concentration requirement of a product.
