Rapid melting plasticizer
Fast melting plasticizers are a class of products that have better solubility than DEHP and thus dissolve or melt PVC resins at lower temperatures. Fast melt plasticizer is generally considered to be an advantage in plasticizing process, because fast melt plasticizer can improve the speed of processing or production line, reduce the cost of operation related to oven, or improve the quality of products.
The lower melting temperature helps to protect the temperature sensitive material. For example, in the PVC backing carpet, fast melt plasticizer can make the product produce at lower temperature, so that it can better protect carpet fibers or backing from thermal degradation.
For the bottom sealant, the lower melting temperature can greatly save the heating cost of the oven. One common drawback of these fast melting plasticizers is that they have higher volatility during processing.
In addition, several kinds of fast melt plasticizers have high density, which usually means that the formula cost will be increased, and they will have poor low temperature flexibility.

The rapid melting properties of MesamollII have also been recognized by alkyl alkyl sulfonate.

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.

It has good compatibility with most industrial resins.
With phthalic anhydride and heptanol as raw materials, sulfuric acid as catalyst, esterification under decompression, crude esterification by neutralization, dealcoholization and pressure filtration, and so on, that is, two phthalic acid two heptane. The proportioning ratio is usually phthalic anhydride: heptanol is 1: 2, sulfuric acid is 0.3% of the total material, and 0.1% to 0.3% of the active carbon is added to the total material.
Two phthalic acid two heptyl ester is the main plasticizer of PVC, compared with two octyl phenyl two carboxylate, its compatibility and plasticizing efficiency are slightly better, and its tensile strength, elongation and cold resistance are basically the same, but the volatility is large. The two heptane of phthalic acid two formic acid can also be used in the copolymers of vinyl chloride, nitrocellulose lacquer and a variety of rubber.
Two propanediol two benzoate is insoluble in water, and the solubility of water in two propanediol two benzoate is 0.45% (25 degrees C). Soluble in aliphatic hydrocarbon and aromatic hydrocarbon solvent, and polyvinyl chloride, ethylene vinyl acetate copolymer, polyvinyl butyral, nitrocellulose, ethyl cellulose, polystyrene, chlorinated rubber have good compatibility.
Two propylene glycol two benzoate viscosity (20 C) 215 centipoise, relative density (25 C) 1.129, freezing point -40 C. Toxicity: two propanediol two benzoate is a low toxic plasticizer.
Two propylene glycol two benzoic acid ester can be used as PVC, polyvinyl acetate and polyurethane resin, plasticizer, solvent effect, good compatibility, low volatility, durability, oil resistance and contamination resistance is also superior, commonly used in high filled PVC flooring materials and extrusion materials, can improve the processing and reduce the processing temperature, shorten the processing cycle. When used for non - filled films, sheets and pipes, the products have good transparency and glossy surface.
