| use | antioxidant for rubber and polymer materials. It has protective effect on aging caused by oxygen or heat. It also has a protective effect on rubber ozone cracking under both static and dynamic conditions. Used in polyolefin nitrile butyl rubber and natural rubber. There is no pollution, and it will not change color when exposed to sunlight. When the amount of butyl glue is large, the color becomes slightly darker during the exposure process. Used to make tire white sidewalls, light color products and latex products. The heat-resistant aging ratio in dry glue is superior to 2246. |
