What rubber kind of rubber does the brake seal of the car use?
Because he is the first production. He asked me. I told him that the first, customer is the name of 15 years ago called, because at that time the brake is so called castor oil, brake oil, castor oil, brake is sensitive enough, the driver should step down to stop with great force, so come now the
The synthesis of liquid to polyethylene glycol or glycol and boric acid ester, because this "oil" may mislead him.

People have encountered such a problem in production: a customer asked him to produce a number of cars on the brakes with seals, resistance brake oil, swelling can not exceed 2%, shore A60. hardness he used nitrile rubber production, detection of customers to pay customers after that swelling failed, he was replaced nitrile rubber grades with nitrile rubber and butadiene acrylonitrile production in 42% and merged with pVC, is still not qualified. This puzzled him.
