The materials and advantages of Fluorescent brightener

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

Factors Analysis on Price Rise This Year of Rubber Additives

According to the China Rubber Additives Trading Network (www.rubberchem.cn) statistics, this year the price of Rubber Additives overall rise. In particular, antioxidant RD, 6PPD, IPPD rose the most (up 34-40%), accelerator DPG or higher (up 30%), accelerator large varieties rose second (up 12% -20%), Small varieties rose at least (not many products prices). According to Zhuo record information statistics, monitoring

Description of the application of the active agent

1.In the sulfur vulcanization accelerator system, the widespread use of zinc oxide and stearic acid as activator 2.When the manufacture of transparent products, because the basic zinc carbonate soluble in rubber, which instead of active zinc oxide, available transparency 3.Non-carbon black reinforcement in the compound can be added polyols, amino alcohols active agent to reduce the silica, clay and other

Environmentally friendly product

With the enhancement of environmental awareness and health concerns, it has been found that the vulcanizing agent DTDM and thiuram products will crack at the sulfidation temperature to release secondary amine-based molecular fragments that can be combined with the nitroso donor to produce carcinogenic Nitrosamine substances, so the curing agent DTDM and Qiu LAM products production and application by the

Countervailing duties

November 3, 2016, the US Customs issued a notice under the WTO rules and the 1930 Tariff Act requirements, the US Department of Commerce in the anti-subsidy preliminary ruling 120 days after the suspension of the imposition of countervailing duties. The US Customs will no longer impose countervailing duties on passenger-car tires imported from China since November 2, 2016. The

Resin vulcanizing agent

Mainly used for butyl rubber vulcanization, so that it has excellent heat resistance and high temperature performance. At present the industry has been widely used, to speed up the curing rate, the general need to add stannous chloride as the active agent. Resin curing agent in the processing of rubber plastic can increase, but vulcanized rubber hardness is higher. The

Multifunctional Amine Compounds

Mainly used for special synthetic rubber, such as acrylic rubber and fluorine rubber cross-linking. Polyamine vulcanized fluorine rubber is characterized by the mechanical strength of vulcanized rubber, compressed water for a long time deformation of small, high-temperature long-term aging can still maintain good physical and mechanical properties, but easy to scorch, the processing safety adverse, and gradually developed a “closed

Peroxide curing agent

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

Sulfur compounds

Sulfur donors are those that release sulfur upon vulcanization and therefore may be sulfur-free or sulfur-less. Products are curing agent DTDM (disulfide dimorphorpholine), disulfide – N, N ‘- lactam, trisulfide bis (diethyl thiophosphoryl), four sulfide diporphorpholine, diethyl disulfide Thiocarbamate, thiocarbamate, thiocarbamate, rubber vulcanization accelerators TMTD, TMTM, TETD, TBTD, DDTS, PTD, DPTT, TBzTD, sulfur monochloride, carbon monoxide, alkylphenol monosulfide, alkylphenol disulfide,

Elemental vulcanizing agent

Typical representative is sulfur, the rubber industry is the most basic and most important curing agent. The vulcanizing agent has the advantages of good comprehensive performance and low cost by using common sulfur-accelerator-activator system. Therefore, in the rubber industry, especially in the tire industry is still dominated. Insoluble sulfur to avoid sulfur, also not easy to burn, can be used
