High temperature resistant plasticizer
High temperature plasticizer is used for injection molding at 300 degrees or so. It can not decompose and volatilize at this temperature. It means that when it is produced, smoke and taste are small. General use of heat-resistant plasticizers, such as TOTM, and polyester plasticizers, also called permanent plasticizers, are very low in volatilization.
TOTM heat-resistant plasticizer, suitable for polyvinyl chloride, vinyl chloride copolymer, nitrate cellulose, polymethyl methacrylate, and other resins.
Characteristics and uses of high temperature resistant plasticizers:
In 1, evaporation, water extraction, migration resistance and low temperature resistance and electrical properties such as good performance, durability and reoplex comparable, and plasticizing efficiency and processing properties and adjacent two formic acid ester plasticizer is similar, with haplotype and reoplex some characteristics. It is mainly used for heat-resistant cable materials (105 degrees centigrade), plate, sheet, sealing mat and so on, which require heat resistant and durable products.
2, with two characteristics, heat resistance and durability, mobility is smaller than polyester plasticizer, and soaping water extraction performance is also much better than polyester plasticizer, thermal stability and solubility, processability and low temperature are better than polyester plasticizer.
The thermal volatilization is less than 136 degrees, and the thermal volatilization is only 4.4%. This product has good electrical insulation performance and is applied to special requirements for heat-resistant durable plates, sheets, gaskets and other products, and 90~105 degrees of cable material. It is also suitable for vinyl chloride copolymers, nitrocellulose, ethyl cellulose, polymethyl methacrylate, and many other plastics.
TOTM plasticizer is mainly used for the production of 105 degrees Celsius heat resistant wire and cable materials and other requirements sheet, heat resistance and durability of the gasket sheet, and other products., for PVC, vinyl chloride copolymer, cellulose nitrate, ethyl butyrate cellulose, polymethyl methacrylate plastics etc.. It can be used for heat resistant and durable products such as heat resistant wire and cable material, plate, sheet metal sealing pad and so on.
Heat resistant and durable main plasticizer, both polyester plasticizer and monomer added advantages of plasticizer, plasticizing efficiency and processing properties and the adjacent benzene two formic acid ester plasticizer is similar; low temperature performance, compatibility, plasticizing performance than polyester plasticizer; excellent electrical performance, but slightly worse oil resistance.

Use of two octyl terephthalate (plasticizer DOTP)
1.DOTP has good electrical and thermal properties. It can be used to replace DOP in the sheath of PVC plastic wire and can also be used in the production of artificial leather membrane. In addition, with excellent compatibility, terephthalic acid ester is two PVC acrylonitrile derivatives plastic plasticizer, plasticizer, plasticizer, polyvinyl butyral nitrile rubber plasticizer, plasticizer for cellulose nitrate. The improvement of the product and plays the role of hardness and deformation, can be used as softener in NBR, chloroprene rubber, EPDM rubber and other products three. Especially for cable material, it has good plasticizing effect and low volatility. It is widely used in various products that require heat resistance and high insulation. It is an ideal plasticizer for producing 70 PVC cable material and other volatile resistant products.
2.DOTP is used for the PVC products in the car, which can solve the fog problem of the glass window. DOTP is also used for high quality lubricants or lubricant additives furniture and interior decoration paint, and precision instruments, nitro varnish additives, paper softener, biaxially oriented polyester amide membrane film, plastic bags and other crafts, plasma storage.
3. because the linear molecular structure of DOTP is similar to DOS and DOA, its cold resistance is also better.
The volume resistivity of 4.DOTP is 10-20 times higher than that of DOP, and its mobility is excellent.
5., because DOTP does not contain o-phthalate two formate, it is not an environmental friendly plasticizer in the range of 16 16 kinds of plasticizers containing o-phthalic acid in the European Union and other countries.
TOTM plasticizer is mainly used for the production of 105 degrees Celsius heat resistant wire and cable materials and other requirements sheet, heat resistance and durability of the gasket sheet, and other products., for PVC, vinyl chloride copolymer, cellulose nitrate, ethyl butyrate cellulose, polymethyl methacrylate plastics etc.. It can be used for heat resistant and durable products such as heat resistant wire and cable material, plate, sheet metal sealing pad and so on.
Polyester plasticizer, chemicals. Widely used in oil and gas pipes, cables, waterproofing materials, artificial leather, shoe material, high temperature resistant wire coating layer, water seal, all kinds of equipment (including refrigeration equipment, motor vehicles) of the gasket, molding; senior interior decoration; electrical tape; oil resistant special products such as gasoline.
Polyester plasticizers are excellent heat-resistant and durable plasticizers because of their large molecular weight, low volatility, small migration, oil resistance and soaping water extraction. The disadvantage is that their plasticizing efficiency is slightly poor, their viscosity is large, and their processability and low temperature are not good. Widely used in oil resistance, high temperature resistant special products, such as: oil resistance, high temperature, high humidity and non migrating cable materials, high temperature resistant wire cladding layer, insulating material, contact for coating, rubber, polystyrene, ABS and organic solvent close products, such as: electric wire, Refreigerator seal pipe and equipment. Oil resistant rubber boots and gloves for flooring, in anti pollution products. In contact with food, it can be used for packaging film, soft drink hose, bottle cap gasket and so on. As the impact modifier used in the hard PVC formula, it can improve the brittleness and toughening effect of PVC resin.
The PVC resin drying method is also designed to maintain a smaller particle size, and a number of spray desiccant are often used. Because it is impossible to completely remove the emulsifier, the resin produced by emulsion method can not be used to produce products that need high transparency, such as packaging film or products requiring low water absorbency, such as wire insulation layer.
Generally speaking, the price of emulsion polymerization of PVC resin is higher than that of suspension polymerization. However, users need to use liquid resin to fill the resin, such as paste resin. In the United States, most of the emulsion polymerized products are paste resin (also called disperse resin), and a small amount of emulsion is used in latex. In Europe, a variety of emulsion processes are also used to produce universal resins, especially for calendering and extrusion.
