Rubber additives in the storage and use of the process often appear sticky, harden crisp or crack and other aging phenomenon, causing this problem, mainly in the following categories: 1. Oxygen: Oxygen will react with the rubber molecules in the rubber additives to cause the molecular chain to break or over-crosslink, so that its performance changes. 2. Thermal: The temperature
Although rubber additives have many types, but the added ways are mostly the same, and there are two main ways: One is the impact of dosing: the general is to reverse osmosis pressure to 0.3Mpa below, the use of drugs should be completed in 2-4 hours. The reason why this will be used, mainly due to the surface of the
1.Additives product structure and variety structure is irrational, uneven quality. For example, in order to meet the requirements of high temperature, fast and efficient rubber processing technology, a large amount of efficient sulfonamide accelerators have been used abroad (the amount of which has reached 55% of the total market of accelerators), easy to prepare, low-tech thiazole accelerators The proportion has
Recently, the Ministry announced the third batch of 2016 industry standard revision plan. Among them, rubber and rubber products – chemical additives in the field three criteria are recommended for the development of the project. It is understood that the announced three standard industry are: curing agent 1,1 two ‘- thiobis caprolactam (CLD) standard, accelerator 3- methyl thiazole -2- copper
Some important country activities influence rubber additives market: 1.2017 April will start 15 provincial environmental protection supervision. 2017 will complete environmental supervision and complete all provinces coverage: will inspect 15 provinces and cities in April including shandong, shanxi, tianjin, anhui, zhejiang, fujian, Shanghai, sichuan, hainan, hunan, guizhou, hainan, xinjiang, liaoning and jilin. 2.2017 April will start one year of continuous
Environmental protection, high efficiency, multi-functional, low cost is the current domestic and foreign rubber additives development direction, in which environmental issues in recent years, especially by the additives and rubber industry attention. Mainly reflected in three aspects: First, the elimination of toxic and harmful rubber additives products, the development of green environment-friendly additives products, such as Hebi Lianhao developed TIBTM,
January 9, 2017, according to the Chinese rubber chemicals trading network statistics, rubber additives products in 2017 continued the gains of last year, the gains is large and supply is tight. Antioxidant RD, 6PPD, IPPD rose 40% last year, this year has gone up 24%; accelerator large varieties rose 10% -17%; accelerator small varieties rose 10%. First, prices in January
1.The North continued haze weather and government environmental supervision, resulting in limited capacity. ◇ Rubber chemicals included in the chemical industry, and a lot of additives in the production process will produce waste water and waste gas, especially the acid-base method of M. Environmental inspection will inevitably affect the industry supply and demand imbalance, the company operating costs increase caused
This year, the price of rubber additives products increase overall. 6PPD, antioxidant RD, IPPD rose 35-40%, accelerator DPG rose as high 35%, and a large variety of vulcanizator DTDM promoter or 15%-25% promoter, recently a small variety of influencing factors also began to rise. The factors that affect the price of rubber additives industry are analyzed as follows, for your
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
