EPDM is a terpolymer of ethylene, propylene and non-conjugated diene. It has excellent properties such as low density, high filling, aging resistance, corrosion resistance, and low temperature elasticity. The products produced by it have the functions of shock absorption, waterproof, sound insulation, heat insulation, dustproof and fixing, and can be used in automobile containers, refrigerated compartments, building curtain walls, system doors and windows, photovoltaic panels and other fields. The high-quality sealant strip has a smooth and detailed surface, matte color, and a slight fragrance unique to rubber. Under natural light, the use of more than 20 years will not appear fracture, elasticity will not disappear, migration and other phenomena. It has excellent anti-aging, high and low temperature resistance and chemical resistance.

The sealing strip of building curtain wall and system door and window is used on door and window components: glass and bead, glass and frame fan, frame and fan, fan and fan, etc. It can prevent the leakage or intrusion of rainwater, air, sand and dust, prevent or reduce the damage caused by mechanical vibration and impact, so as to achieve the functions of sealing, sound insulation, heat insulation and shock absorption. Sealing strip is a key part of door and window fittings.

Automobile sealing strips are mainly used in the gaps of automobile doors, windows, hatch covers, carriages, etc., to play a sealing role and prevent external sand, rain, dust and other harmful substances from entering the car. Some are for shock absorption, sound insulation, The role of warmth and decoration to improve the working life of auto parts and ride comfort.

Anhui Gurite New Material Technology Co., Ltd. was founded in 2018 and now has a rubber mixing center, two EPDM microwave production lines and production equipment and testing equipment such as flat vulcanizer, rheometer, Mooney viscosity machine and electronic tension machine. It has a rubber and plastic material research center, a rubber and plastic physical and chemical testing center, and a "Green Nano Material Joint Research and Development Center" in cooperation with Beijing University of Chemical Technology ", it has been recognized as" Anhui Rubber and Plastic Additives Engineering Technology Research Center "and" Anhui Enterprise Technology Center ", and has been approved to be established as a post-doctoral workstation in Anhui Province. The company has passed the ISO9000 quality management system certification and ISO/TS16949:2002 quality management system certification and other authoritative certification.

Our company is not only a manufacturer of products, at the same time, the company connects upstream and downstream and makes full use of its own advantages to successfully develop EPDM rubber mixing dispersant Youjiao and C919 reinforcing agent.

Youguin has excellent physical lubrication, which can improve the fluidity of the rubber compound and increase the extrusion speed. Promote the rapid and uniform dispersion of various additives and fillers, extend the vulcanization flat period, shorten the mixing time, reduce energy consumption, and prevent tearing and edge breakage. It can increase the uniformity and stability of each batch of the rubber compound, effectively reduce the temperature rise of the rubber compound, and ensure that the rubber compound has good processing performance in the next process. It can significantly improve the tensile strength and physical and mechanical properties of the rubber compound, increase the surface smoothness of the product, and improve the appearance quality of the product. The influence of various processing aids at home and abroad on the reduction of the fixed elongation strength is overcome. The usual dosage is 1.5-3.0phr, which can be used together with small materials.

CR919 reinforcing agent is an inorganic-organic composite material, which is prepared by ultrafine grinding and surface modification. The product has the characteristics of low specific surface, amorphous, microporous, amorphous and so on. At the same time, it has the characteristics of high surface activity, good lubricity and compatibility, easy processing and fast dispersion. After being applied to EPDM rubber, it can improve the tensile strength of the rubber, enhance the wear resistance and flex resistance of the rubber, and increase the surface brightness of the rubber.
