1、Special rubber compounding rubber industry overviewCompound rubber: is a kind of rubber material formed after mixing and processing of carbon black, vulcanizing agent and other cooperating agents dispersed in the raw rubber. Through the addition of a variety of matching agents can greatly enhance the physical and chemical properties of the raw rubber, rubber compounding is the key material for the production of rubber products, but also from the raw material to the transition state of rubber products.Special rubber compounding rubber: It refers to the compounding rubber material used for processing into special rubber (synthetic rubber with special performance and special purpose, which can be adapted to the use of harsh conditions), and it is the intermediate transition state from raw rubber to special rubber products, and the main categories are nitrile rubber compound, fluoroelastomer compound, hydrogenated nitrile rubber compound and so on.Special rubber compounding rubber gel dispersion quality is directly related to the quality of special rubber finished products, while the viscoelasticity and rheology of the rubber compounding rubber directly affects the operation and processing performance of the rubber material and the later production of molding, extruding, calendering, extrusion, and other processing techniques.2、Special rubber compounding rubber industry chain structureSpecial rubber compounding rubber industry chain upstream raw materials mainly include rubber rubber, carbon black, accelerator, filler, etc., through the mechanical force (including shear, stretching, tearing, meshing, etc.) effect of uniform mixing and processing to get special rubber compounding rubber. The above raw materials are conventional chemical processing raw materials, the market source is relatively rich, raw material costs and commodity price trends have a high correlation.In the middle of the industry chain, there are many enterprises involved in the special rubber compounding rubber processing market, and the product types are relatively rich, the main categories are nitrile rubber compounding rubber, fluorine rubber compounding rubber, hydrogenated nitrile rubber compounding rubber, etc. Due to the complexity and diversity of downstream customer demand, the production enterprises usually build a professional R&D team to carry out continuous practice and innovation, and research and develop and reserve material formulas with different properties, and carry out continuous improvement and upgrading.Downstream of the industrial chain, using molding, extrusion, calendering and other processes, special rubber compounding rubber at high temperatures into various types of special rubber products, widely used in automotive, electronics, electric power, equipment manufacturing, aerospace and other fields.3,The Global Special Rubber Compounding Rubber Market SizeAs early as the beginning of the 20th century, the global market began to special rubber compounding rubber R & D and processing, and then with the rapid increase in the level of R & D, the global special rubber compounding rubber processing market continues to emerge new process innovations, material innovations, such as resistance to high temperatures, resistance to strong corrosion, resistance to ozone, light, weathering, radiation, and oil and other performance indicators continue to improve, and its downstream applications continue to expand. 2021-2023 Global Specialty Rubber Compound Adhesive Market size were 5.69 billion yuan, 6.23 billion yuan, 6.85 billion yuan.
Rubber and plastic seals is an important basic component of mechanical products, its manufacturing precision requirements are high, with China's automobile manufacturing and automobile ownership of the rapid growth of sealing products, whether in the structure or materials need to be supported by high-precision technology and equipment. In recent years, China's seals in the professional production of some enterprises in line with the market positioning, timely adjustment of industrial structure and product structure, rapid development and growth. In the rapid increase in production value of production at the same time, in the production and testing of experimental equipment also made a greater investment.Rubber and plastic sealing materials development trendsRubber and plastic seals commonly used nitrile, hydrogenated nitrile, fluoroelastomer, acrylate rubber, PTFE and other special rubber and plastic material formulations and processing technology research to improve the performance of the material is still the focus of the work of performance and utilization. The application of nanomaterials will enhance the mechanical properties of rubber and plastic materials and special features. April 1 this year, the National Standardization Committee promulgated the implementation of China's first four nanomaterials in the national standard, there is a rubber "nano zinc oxide" standard.Special engineering elastomers instead of low performance oil-resistant rubber; rubber bright surface treatment; through nanotechnology modification of rubber and plastic materials and the application of liquid rubber materials, have made some progress in recent years. In particular, the recent application of some new materials, rubber and plastic sealing technology has played a great role in promoting.China's relatively weak application of thermoplastic elastomers in seals (TPE) with the physical properties of vulcanized rubber and thermoplastic resin process performance, the molding process does not require vulcanization, and thus was used as the third generation of rubber. The main varieties of TPO, TPV, TPU has been widely used in the world: TPV in the automotive application of an average annual growth of 15%, generally EPDN and PP full crosslinking compounds, which combines high tensile strength, oil and heat resistance, and other properties, can be a long time to resist the 150 ℃ hot oil conditions, can be used to replace the EPDM production of automotive seals and other products; TPO is currently used more than the ternary TPO is currently used more EPDM and polyethylene components, the production process has a mechanical blending method and dynamic vulcanization method. Dynamic vulcanization method for the production of TPO. Rubber components up to 60 ~ 70%, abrasion resistance, ozone resistance, high tear strength, compression deformation is small, the overall performance is better than EPDM vulcanized rubber.The United States, Western Europe and Asia are continuing to build additional TPO production units; TPU both plastic and excellent processing properties and physical properties of rubber, its wear resistance, low temperature resistance, excellent radiation resistance, in the automotive, aerospace, medical and health care, household goods, military supplies and other industrial applications have made great progress, TPU can be widely used in automotive shock absorbing pads, bushings, bushes, airbags and other parts.
