Rubber products with excellent properties, such as strength, air tightness, water resistance, already in the pipeline resistance, lining, dynamic, static sealing and damping, shock absorption, etc, has been widely applied. But rubber products in use will be affected by heat, oxygen, water vapor, ultraviolet light erosion occurs in aging, and aging performance is good or bad directly affects its service life, especially the higher requirements for reliability and service life of rubber products, in order to guarantee the reliability of the product, can be used in production, before the reliability test, such as ultraviolet aging test, xenon lamp aging test, ozone aging test, thermal aging test, high temperature aging test, sulfur dioxide experiment, cold and hot test, tide tide, etc. After test and other related physical properties of product testing, testing, through the test to determine whether the performance of the product can meet the requirements, so that its formula optimization, physical blending modification, use, such as packing enhancement prolongs its service life, so that the rubber products apply to the higher products.
