Rubber seals Study on formula and processing technology of Ding Jing, Ding Jing, hydrogenated fluorine rubber, acrylic rubber, PTFE and other special rubber materials commonly used materials, improve application performance and utilization rate is still the focus of the work. The application of nano materials will enhance the mechanical properties of rubber materials and special features. Four nano materials GB China's first in April 1st of this year the National Standardization Committee promulgated the implementation, one is for rubber "nano zinc oxide" standard. Special engineering elastic body instead of low performance of oil resistant rubber; rubber surface for surface treatment; and through the application of liquid rubber material of rubber materials nanotechnology in recent years have made some progress. Especially the recent application of new materials, the rubber sealing technology plays a very important role. In our country the seal application of relatively weak thermoplastic elastomer (TPE) process with the physical properties of vulcanized rubber properties and thermoplastic resin, molding process without vulcanization, which is regarded as the third generation of rubber. The main varieties of TPO, TPV and TPU have been widely used in the world: the average annual TPV growth of 15% in the automotive applications, are generally cross-linked compounds EPDN and PP, the combination of high tensile strength, oil resistance, heat resistance and other properties, long-term high temperature of 150 DEG C hot working conditions, can be used for replacing EPDM cars seals and other products; TPO currently used more is three yuan and polyethylene components, the production process with mechanical blending method and dynamic vulcanization method. Dynamic vulcanization method for the production of TPO. The rubber component is as high as 60 ~ 70%, abrasion resistance, ozone resistance, high tear strength, small deformation, three vulcanized EPDM rubber has better comprehensive performance than.

The United States, Western Europe and Asia were on an TPO production plant; TPU and physical properties and processing properties of rubber and plastics is excellent, its wear resistance, low temperature resistance, good radiation resistance, in the automotive, aerospace, medical and health, daily necessities, in the dream real edge to Di Yi tau magnesium purging their stems Qiu Wan PU can be widely used in automobile cushion, bushings, bearings, bushings, airbags and other parts.
