Development trend of rubber and plastic sealing materials
The formulation and processing technology of special rubber and plastic materials such as nitrile, hydrogenated nitrile, fluoro rubber, acrylate rubber, and polytetrafluoroethylene are commonly used in rubber and plastic seals, are still the focus of work to improve the applicable properties and utilization of materials. The application of nanomaterials will enhance the mechanical properties and special functions of rubber and plastic materials. One of the first four national standards for nanomaterials issued by the National Standardization Committee on April 1 this year was the “Nano-Zinc Oxide” standard for rubber.
Special engineering elastomers replace low-performance oil-resistant rubber; surface treatment of rubber bright surfaces; modification of rubber-plastic materials and application of liquid rubber materials through nanotechnology, and recent progress has been made. In particular, the application of some new materials soon has greatly promoted rubber and plastic sealing technology.
China's relatively weak thermoplastic elastomer (TPE) used in seals has the physical properties of vulcanized rubber and the processing properties of thermoplastic resins. The molding process does not require vulcanization and is therefore used as the third-generation rubber. TPO, TPV., and TPU in the main varieties have been widely used globally: TPV has an average annual growth of 15% in automotive applications, generally a full cross-linking compound of EPD and PP, which combines high tensile strength, oil resistance, and heat resistance. Performance, long-term resistance to 150 ° C hot oil working conditions, can replace EPDM production of automotive seals and other products; TPO is currently used more is composed of EPDM and polyethylene components, the production process has mechanical blending And dynamic vulcanization. Dynamically vulcanized by TPO. The rubber component is as high as 60-70%, wear resistance, ozone resistance, high tear strength, small compression deformation, and overall performance is superior to EPDM rubber.
The United States, Western Europe, and Asia continue to build TPO production facilities; TPU has excellent processing properties and physical properties of rubber. Its wear, low temperature, and radiation resistance are excellent in automotive, aerospace, and medical care. Daily necessities, military, and the like can be widely used in automotive cushions bushings, bushings, airbags, and other components.
