Tongxiang Chemical Co., Ltd. was founded in 1960s and has engaged in researching and producing plastic additives. Our products coverage the whole country and dominate the East China. In 2003, by introducing foreign investment, we established Jintong Chemical Co., Ltd. to manufacture new types of plasticizer with high quality. Our company is located in Tongxiang Economic Development Zone. It is an excellent geographical location in Hangjiahu Plain, which is adjacent to Shanghai, Hangzhou and Suzhou. In addition, we have convenient transportation condition with G60, S12, S13 highway and Shanghai-Hangzhou high-speed railway has a station in Tongxiang. Meanwhile, our company has advanced production equipment and testing instrument. We strictly control the quality of raw material and final product. And we will make our efforts to complete quality guarantee system. Our "Wutong" and "Jintong" brand products won wide support by reliable and stable quality. We have passed ISO9001-2008 quality system authentication.

From December 28th to 29th, 2013, the company organized all middle-level managers to go to Hangzhou Xiaoshan for management improvement training and annual summary. The theme of the training is “Growth Breakthrough, Efficiency Management”. In order to ensure the learning effect, special training teachers are invited to give lectures. Through micro-movies, business cases, etc., we analyze the reasons that hinder the growth of enterprises, break through the barriers of thinking, turn problem thinking into growth thinking, and transmit the concept of efficiency first, so that employees can work with growth goals. Through training, the company's senior executives have expressed their benefits, not only have gained the renewal of ideas and ideas, but also unified their understanding of some issues. After the management training, the company held an annual mid-level summary meeting, and each department made a summary report.

At the end of the meeting, everyone visited the beautiful Xianghu Lake, visited the Cross Lake Bridge Site Museum and the Xia Sun Culture Village, and relaxed their mood after the intense work!  "The heart is in the distance, the road is at the foot." I am sure that as long as we work together, Tongxiang Chemical will definitely be better tomorrow!  

 

DOP ( CAS No. 117-81-7) is the abbreviation of Dioctyl phthalate, also known as Di(2-ethylhexyl) phthalate. The abbreviation code for plasticizers is clearly defined in the national standard GB/T 1844.3 "Plastic symbols and abbreviations part 3: plasticizers", in the "Synthetic Materials Additives Handbook", "Plastic Auxiliary Manual", The Handbook of Plastic and Rubber Processing Aids, the Encyclopedia of Chemical Industry, and the Encyclopedia of China Chemical Products are all described in the books. If it refers to a plasticizer, DEHA is DOA, DEHP or DOP. Why DEHA and DEHP can be well known to the public, the former began in October 2005 with the PVC cling film storm, the latter in the May 2011 Taiwan "plasticizer event." In 2005 and this year, the "PVC cling film suspected cloud" that has been raging twice has proved that "it is just an oolong" (see "China Chemical News" reported on August 2, 2013). In fact, enterprises in Taiwan (such as Changchun Enterprise Group http://www.ccp.com.tw/, Nanya Plastics Industry Co., Ltd. http://www.npc.com.tw/) call plasticizer (Plasticizer) It is a plasticizer and there is no plasticizer. DEHA and DEHP evolved from the English names Di(2-ethylhexyl) adipate and Di(2-ethylhexyl) phthalate. They first appeared in foreign-invested enterprises, and were not standardized in mainland China. The South Asian webpage also uses DOP. Non-DEHP. Abbreviations or codes consisting of several English letters have their specific scope in use, otherwise they cannot determine their true meaning, such as DOS, in the plasticizer industry, "dioctyl sebacate", and in the computer industry "Disk Operating System." Standard language is very important, especially in the field of science and technology.

Right now, a rumor about the dangers of plastic wrap on human health has been wavering. Recently, there are well-known domestic media reports: "The PVC cling film production industry is shrouded in multiple layers of fog. Behind the fog is a lie involving the cling film industry and its upstream chemical industry. Plasticizers used in cling film (also known as plasticizers) The raw material of DOA is n-octanol, and the raw material of plasticizer DEHA is isooctyl alcohol. The prices of these two raw materials are very different. In order to reduce the cost, enterprises use isooctyl alcohol as raw material to produce DOA.” “Many plasticizer production The plasticizer DEHA product that the company prohibits is affixed with the plasticizer DOA package that is allowed to be used, and the qualified raw materials are provided to the plastic wrap production enterprise.” “The main hazard of plasticizer is the hormone that affects the human body, leading to the endocrine system. Disorders, easy to induce female precocious puberty, male infertility, etc., especially have a great impact on the genital development of infants and young children."

Octanol is the most used alcohol in the plasticizer industry. Its chemical name is 2-ethylhexanol. The current market standard for commercial products is: GB/T 6618-93 "Industrial Octanol (2-Ethylhexanol)" 2-Ethyl hexanol for industrial use. CAS No.: 104-76-7 Molecular structure: Widely used in the production of dioctyl phthalate (DOP), dioctyl terephthalate (DOTP), trioctyl trimellitate (TOTM), dioctyl adipate (DOA), azelaic acid Dioctyl ester (DOS) and so on. Although 2-ethylhexanol is also a kind of isooctanol from the organic chemical nomenclature, it is customarily called octanol because it is the most commonly used 8-carbon alcohol. Isooctanol. Isooctyl alcohol refers specifically to a mixed alcohol of various dimethylhexanol and methylheptanol. Linear n-octanol can not be simply referred to as octanol, otherwise it is easy to misunderstand.
