Polyol benzoate plasticizer
A polyol polyol benzoate plasticizer was developed with polyol as the raw material. Natural polyol plasticizers are superior to traditional plasticizers in terms of their gloss and transparency as compared with traditional plasticizers.
Polyol benzoate plasticizer is a colorless or white oil like transparent liquid. Flash point: (open cup C) = 195, the proportion of 20/30: D 1.072-1.076, 125 / 2 C heating loss less than 0.3 hours. Insoluble in water, in PVC and ethylene vinyl acetate copolymer, polyvinyl acetate with good compatibility, and PVC, PMMA, polyvinyl butyral, nitrocellulose, butyl acetate and ethyl cellulose fibers such as miscibility. The phase solubility, mechanical, machinability, and pollution resistance are all superior to DOP, and are the 8611 upgrading and replacement products in China.
Acid polyol ester plasticizer is polyvinyl acetate and the main plasticizer, low processing temperature, plasticizing time is short, can be used for PVC and asbestos flooring material and extruding plastic, filled with non calendered film, calendered film, printing film, artificial leather, gas pipes, rubber strip, coated cloth, foam mat Su sheet, profiles, pipes, shoes and various foam materials, polyvinyl acetate emulsion adhesive and part of the cable granulator industry.
Plastics industry through years of practice proved that the acid polyol ester plasticizer plasticized with high efficiency, good solubility, high safety factor, the characteristics of a good flexible products, more important is if the goods and genuine DOP, DBP, and the plasticizing effect is better, greatly reduces the cost objective. In addition, printing ink can be used.
Polyol benzoate is one of the most important plasticizers, with different properties and wide use. It is precisely because of the importance of such plasticizers that some people have been particularly concerned. Some enterprises have different interpretations of the concept of polyol benzoate for various purposes. In fact, polyol benzoate is a category, not a specific plasticizer product. Therefore, it is unthinkable to sell polyol benzoate as a product (except for the mixture).
Polyol benzoate is an important category of polyol ester plasticizers. Here is a polyol, diols and more than two yuan of alcohol, such as ethylene glycol, diethylene glycol two, two propylene glycol, diethylene glycol, polyethylene glycol three, poly propylene glycol, butylene glycol, glycerol, pentaerythritol, neopentyl glycol, sorbitol, sucrose, three 2,2,4- methyl -1,3- diol, glycerol ester of lactic acid etc. here; benzoic acid can be single, it can be more than one.
Polyol benzoate is a monoester or polyester of polyol and benzoic acid. The most common polyol benzoic esters were two glycols, two benzoic esters (DEDB), two propanediol two benzoic esters (DPGDB), two triethylene glycol two benzoic esters (TEDB), 2,2,4- three methyl -1,3- butanediol isobutyrate benzoic acid ester and so on.
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.
Packing method:
200KG/ net galvanized steel drum (a small pallet loaded 16 tons), 1000KG/IB (a small barrel loaded 18 tons or 23 tons of ISOTANK).
Polyol benzoates are usually colorless, stable crystalline solids or liquids with high melting point, but branched chain alcohols often have much lower melting point than benzyl esters of corresponding straight chain alcohols. These compounds are too slow to be supercooled and recrystallized.
The compatibility of polyol benzoate is low. If the polymer is compatible with the polymer, it will be frosting or precipitating from the surface of the product as time goes on. But when other additives, polymers or plasticizers are added to the formula, the compatibility of polyol benzoate can be improved.
Polyol benzoate is insoluble in water (relatively large molecular weight polyethylene glycol ester can be dissolved or dispersed in water), soluble in aromatic hydrocarbons, alcohols, ketones, esters and ethers. UV resistant and thermal stability. It has good compatibility in solvent film. But it is incompatible in the thermal film without solvent.
Polyol two benzoate is an important plasticizer of polyvinyl chloride, polyvinyl acetate and a variety of resin and emulsion adhesives. Strong solubility, good compatibility, oil resistance, water resistance, light resistance, resistance to pollution, and mineral oil extraction. It can quickly dissolve the vinyl resin, shorten the melting time and reduce the melting temperature. When used as a vinyl resin plasticizer, the allowable amount of the filler can be increased, thus increasing its tensile strength.
Polyol three benzoic esters (such as glycerol, three benzoate, glycerol mono lactate, three benzoic ester, etc.) and polyols four benzoic esters (such as pentaerythritol, four benzoic ester, etc.) volatilized faster than the same molecular weight haplotype plasticizer. Glycerol three benzoate has a similar plasticizing property to vinyl resin and acrylic resin, and is similar to phthalic acid two bicyclic ester. It is UV resistant, stable in thermal degradation and slow in open cup evaporation. It is about 1/20 of DOP. It is the most important solid plasticizer.
Two propanediol two benzoate is a monosomatoplasticizer and a strong solvent for PVC resin. It is especially suitable for vinyl flooring, plastic extrusion, plastic, film, sheet, coated fabric, paper and electrical appliance sheath. It can also be used in latex paints, polyvinyl acetate, adhesives and cellulose plastics. Two propanediol two benzoate is a good plasticizer in the cast - plastic polyurethane elastomer. It is highly compatible with the pre polymer, and also gives the elastomer excellent durability, lower hardness, better tensile strength and softness.
