III. Product overview: Plasticizers are essential auxiliary materials used in the production of plastic products. Phthalate plasticizers (such as DOP) are currently widely used. Due to their aromatic rings, they are not easily biodegradable; they are non-renewable petrochemical products, and they may also be carcinogenic. In particular, in the European Union, their use and application scope are heavily restricted, which has a significant impact on the export of products from our country. Under the general trend of low carbon and environmental protection, it has become inevitable to use natural renewable resources to produce environmentally friendly plastic plasticizers. As a new type of environmentally friendly plasticizer, chloro fatty acid methyl ester products are derived from natural oils; they contain no harmful metals or phthalate substances. They represent a cost-effective alternative to DOP-based plasticizers and meet the export requirements of the European Union. Methyl chlorofatty acid ester, as a plasticizer, is in line with the current global trend toward environmental protection and international environmental standards. A new generation of chlorinated fatty acid ester plasticizers, these products are formed through an esterification reaction between natural oils and alcohols, followed by a chlorination process, resulting in compounds with high molecular weights. They serve as alternatives to the mainstream environmentally friendly biological plasticizers currently available on the market. These plasticizers have good solubility in PVC and offer excellent plasticizing effects; they are flame-retardant, non-toxic, and environmentally friendly composite plasticizers. They are particularly suitable for use in export products, as well as in industries such as PVC flame-retardant conveyor belts, cable materials, PVC rain boots, PVC hoses, automotive interior leather, synthetic leather, and sealing strips. It can completely replace chlorinated paraffins 42# and 52#, as well as dioctyl phthalate and dibutyl phthalate. It is colorless and odorless, does not emit oil, and offers stable quality. It can replace 30–40% of DOP in PVC hoses, and up to 50% of DOP in products such as floor mats. At present, this product has been widely used in Weifang and Qingdao in Shandong Province, Wuxi in Jiangsu Province, and other places. Due to its ester structure and the absence of harmful metals and phthalates, this product can replace tributyl citrate (TBC) as an environmentally friendly plasticizer, as well as DOP and DBP. It also contains chlorine, **which improves the flame-retardant and electrical insulation properties of the product. It is an ideal new type of environmentally friendly composite plasticizer. IV. Advantages of the product: 1. Environmentally friendly – it does not contain any harmful phthalate substances. Made from plant oils, it complies with the EU REACH regulations. It can be widely used in mid-to-high-end PVC products, such as foamed PVC synthetic leather, clothing leather, packaging materials, children’s toys, home decoration materials, agricultural nozzles, fire hoses, gloves, PVC soft products, as well as transparent bottles and boxes. 2. It contains the halogen chlorine, offering good flame-retardant properties and excellent resistance to precipitation; a large amount of it can be added to the formulation. 3. The product has a high volume resistivity, which is one order of magnitude higher than that of ordinary plasticizers. 4. It can increase the tensile strength of the product. 5. It offers excellent plasticizing effects, good compatibility with other ingredients, and strong bonding to PVC resin molecules, thereby enhancing the flexibility of the products. 6. It possesses a certain degree of stability, which allows for reduced usage of stabilizers and thus lowers production costs. V. Applications: Years of experience in the plastics industry have shown that this product features high plasticizing efficiency, good compatibility, a high safety factor, and excellent flexibility in the resulting products. Widely used in various plastic films, wires, cable granulation, etc ； Gas pipes, rubber and plastic strips, heat-shrinkable sleeves, foam sheets, pipes, Teslin ； Unfilled calendered films, printed films, and the artificial leather industry. It is used in PVC cable materials, PVC transparent materials, PVC profiles, polyurethane, seals for doors, windows, and car windows, various types of films, flexible and rigid pipes, plastic sandals, foam sandals, soft boards, coatings, adhesives, bonding agents, decorative materials, foamed rigid boards, and all other products that require plasticizers; it can help companies reduce their production costs by more than 30%. VI. Production process: The new type of plastic plasticizer, chloromethyl ester, is a methyl ester of chlorinated fatty acids produced by reacting vegetable oil and chlorine as primary raw materials in the presence of a catalyst. The production technology utilizes the most advanced process equipment available in China, resulting in products with good color, low acidity, high production capacity, and low energy consumption ； The entire production process is carried out using DCS for continuous manufacturing; aside from the by-product salt acid, no other waste materials are generated, making it a clean production process. This environmentally friendly plasticizer is easy to produce on a large scale, and it is suitable for chlor-alkali companies or those that currently produce chlorinated paraffins to carry out upgrades. A few companies in China are already producing it; those interested can get in touch to discuss further.
