1. Application in automobile tire and power vehicle tire:
Butyl rubber has excellent heat resistance and tear resistance. The inner tubes (including motorcycles and bicycles) made of butyl rubber can still maintain good tensile and tear strength after long-term exposure to the thermal environment, which reduces the risk of bursting during use. The butyl rubber inner tube can still ensure the maximum tire life and safety under high temperature conditions or under inflated conditions. The smaller tear can reduce the size of the hole and make the repair of the butyl rubber inner tube easier and convenient. The excellent oxidation resistance and ozone resistance of butyl rubber make butyl rubber inner tube have excellent degradation resistance, and its durability and service life are better than natural rubber inner tube. The extremely low air permeability of butyl rubber enables the inner tube made of it to be kept at the correct inflation pressure for a long time. This unique performance enables the tire outer tube to wear evenly and ensures the best crown life. Extend the service life of the outer tire, increase the stability and safety of driving, reduce the rolling resistance, and then reduce the fuel consumption to achieve the purpose of energy saving.
2. Application in medical bottle stopper:
Medical bottle stopper is a special rubber product for sealing and packaging that directly contacts with drugs. Its performance and quality directly affect the effectiveness, safety, quality stability and convenience of drugs. Medical corks are often sterilized under high temperature and high pressure conditions or in various disinfectants, and sometimes they need to be stored for a long time under low temperature conditions. Therefore, there are strict requirements on the chemical properties, physical mechanical properties and biological properties of the rubber. Since the bottle stopper is in direct contact with the drug, it may contaminate the drug due to the dispersion of the extractable substance in the bottle stopper into the drug, or reduce the activity of the drug due to the absorption of some components in the drug by the bottle stopper. Butyl rubber not only has low permeability, but also has excellent oxidation resistance, acid and alkali resistance, heat resistance and chemical damage resistance. After the butyl rubber bottle stopper is used, the pharmaceutical factory can simplify the sub packaging process, use the open aluminum cap, eliminate the sealing wax and reduce the cost, and can also facilitate the injection use.
3. Other applications:
In addition to the above uses, butyl rubber has the following uses: (1) lining of chemical equipment. Due to its excellent chemical corrosion resistance, butyl rubber has become the preferred material for corrosion resistant lining of chemical equipment. The volume swelling of butyl rubber in various solvents is very low, which is one of the important reasons why butyl rubber is used in this field. (2) Protective clothing and protective articles. Although many plastic materials have good isolation and protection performance, only elastic materials can give consideration to the flexibility necessary for low permeability and comfortable clothing. Because of its low permeability to liquids and gases, butyl rubber is widely used in protective clothing, ponchos, protective covers, gas masks, gloves, rubber overshoes and boots.
