Rubber shock block generally use natural rubber and neoprene, requiring oil-resistant using nitrile rubber, requiring high and low temperature resistant using silicone rubber, requiring high damping using butyl rubber. Rubber shock pad products manufacturing process, in addition to rubber air spring similar to the tire, the majority are similar to model products. Usually made into support or connectors, widely used
First: raw rubber system 1) Rubber and plastic is a very common means, and with high styrene, PVC / NBR alloy effect can also be hardened. 2) Change the type of plastic grades, but also can improve the hardness. Second: vulcanization promotion system 1) By increasing the curing agent to increase the cross-chain density, increase the hardness, such as increased
January 1, China Export Tire Quality Technology Promotion Committee issued export tire enterprises” on the same line with the standard homogeneous “that the criteria. The establishment of tire product “the same line with the standard homogeneous” quality and safety supervision mode, to accelerate the tire products “with the same line with the standard homogeneous” that provide system protection, the initial
Integrated the news of Thai media 28th December, the Thai Ministry of Commerce statistics show that rubber exports amounted to 3.9 billion 41.1 million US dollars at 11st Jan, 2016, down 15.91 percent. The top three rubber export markets are mainland China was about 1.811 billion US dollars, slip 21.35%; Malaysia was $ 524 million, slip 11.06%; and Japan, about
Many provinces and municipalities in the northern region started heavy pollution in the red (I) early warning from 0:00 December 17th to December 22nd, and in accordance with the corresponding requirements to implement emergency response measures, which is not good news to the rubber chemicals industry, because manufacturers are mainly concentrated in the north. The impact on the industry as
The IRC 2016 held in Kitakyushu, Japan on October 24 (Mon.) – 28 (Fri.), 2016 under sponsorship of the Society of Rubber Science and Technology, Japan. The conference is to make an important contribution to the advancement of rubber science and engineering, including industrial technology. Rubber scientists and engineers throughout the world were all cordially invited to the Conference. Nanjing
Fluorescent brightener industry in China is still a fully competitive industry. In addition, the country’s policy background, environmental factors can not be ignored. With the strict implementation of environmental protection requirements of the state, some poor environmental awareness of fluorescent whitening agent production enterprises will be more difficult to survive, or even face the danger of being eliminated due to
The decomposition of organic peroxides and their crosslinking are free radical reactions. As the curing agent peroxide should meet the storage stability, safe processing operations, do not cause scorch, to decomposition temperature can quickly decompose, high cross-linking efficiency requirements. With peroxide curing rubber, in general, with a short curing time, good thermal stability of vulcanized rubber, heat aging, low compression
Polyether defoamer is a non-ionic surfactant with excellent defoaming, anti-foaming function, non-toxic, insoluble in water, soluble in organic solvents, can be used alone, can also be used as emulsion, which GPE type Particularly suitable for fermentation industry, PPE suitable for high temperature use. The product has the advantages of polyether and silicone antifoaming agent, can defoaming and defoaming of different media, and
Mineral oil defoamers applied for all types of synthetic latex, in particular applied to rubber and plastics industry polymerization, condensation,degassing step,can eliminate foam produced by different surfactants in this system. And it can also be used in resins, water-based paint, latex paint, water-based ink, emulsion polymerization, polymer gel, lotion benzene Bing black liquor, petrochemical and all NA silicone defoamers industry.
