Polyurethane rubber

   Valve rubber is also called "valve rubber", and the main material is polyurethane. Polyurethane products are an emerging organic polymer material, which is now used in many fields. Its main features are oil resistance, corrosion resistance, wear resistance and so on. Can withstand high pressure.

The most common one is used on oil field fracturing trucks. Because when the fracturing truck is operating in the underground oil field, cracks will be formed to achieve the purpose of increasing production. The second fracturing truck has three water inlets and three water outlets. If the water outlet is to be opened in the well, it must be sealed with high-pressure rubber rubber.

Different oilfields have different requirements for Vail rubber seals.
