Chlorinated methyl ester, the full name of the methyl ester of chlorinated methoxy fatty acid, as a new environmentally friendly plasticizer, it’s raw materials derived from natural oils and fats, in line with the current world environmental trends and international environmental requirements, and good compatibility with PVC, is a cheap DOP plasticizer substitutes.
Through many years of practice in the plastics industry has proved that this product has high plasticizing efficiency, good compatibility, safety factor, product flexibility and good characteristics. It is widely used in various types of plastic film, wire, cable granulation, such as gas pipe, rubber and plastic strips, heat shrinkable casing, foam sheet, pipe, special forest, non-filled calendering film, printing film, artificial leather industry.
Used in PVC cable material, PVC transparent material, PVC profile, polyurethane, windows and doors and windows sealing strip, a variety of films, soft and hard pipe, plastic sandals, foam sandals, soft board, paint, glue, adhesives, decorative materials, foam and so on all the use of plasticizer products, can reduce the production cost of more than 30% of enterprises.
Application principle: Increase the flexibility of PVC products, and enhance the cold resistance and heat-resisting effect of PVC products.
Application characteristics: 1, environmental protection, does not contain O-benzene harmful substances, the product is made of vegetable oil, can be used in the EU REACH regulation, widely used in high-end PVC products, such as foam PVC leather, garment leather, packaging materials, children's toys, home decoration materials, agricultural nozzles, fire hose, gloves, PVC soft Products as well as transparent bottles, transparent boxes and other fields. 2, contains halogen chlorine, good flame retardant effect, excellent anti-precipitation effect, in the formula to add a large amount. 3, the product volume resistivity is larger than the ordinary plasticizer an order of magnitude higher.
4, increase the tensile strength of the product. 5. excellent plasticizing effect, good compatibility with other raw materials, strong adhesion with PVC resin molecule, improve flexibility of products. 6, with certain stability, can reduce the use of stabilizers, reduce production costs. Chlorinated methyl ester plasticizer use: General hard products do not need to add PVC plasticizer or a little more can be. Some cases in order to improve processing liquidity will choose to add several PVC plasticizers. But if it's a soft product, you need to add a lot of PVC plasticizers because the greater the amount of soft products, the softer the product. So give us a summary of the total amount of PVC plasticizer, should be based on the softness of the product requirements and use, technology and use of the environment to add our daily situation. under calendering process production of PVC film, the total amount of plasticizer in about 50 parts. Blown film slightly lower, generally around 45 minutes is enough.
What problems should be noted for the use of methyl chloride plasticizers? 1, plasticizer and resin compatibility, in general, the additives only with the resin has good compatibility: In order to make the auxiliaries long-term, stable, evenly in the production of apricot in the product, effectively play its function, if the compatibility is not good, prone to "sweating" or "spray frost" phenomenon, but sometimes not good compatibility, product requirements are not too strict, can still have poor compatibility, such as the filler and tree wax compatibility between very poor, as long as the size of the filler is small, still can basically meet the product performance requirements, obviously with coupling agent or surfactant treatment, in order to fully exert its function. 2, plasticizer adaptability to processing conditions: some resin processing bar with more stringent, such as high processing temperature, should consider whether the selected additives will be decomposed, additives on the mold, equipment has corrosive effect. 3, the use of products for the restriction of additives: the use of different products for the additives odor, toxicity, electrical, thermal performance, etc. have certain requirements.
