Soft PVC plasticizer
When choosing suitable plasticizers for most soft PVC products, soft PVC plasticizers usually first consider DINP or DIDP general plasticizers, and then adjust the formula to achieve the required hardness or other performance characteristics, or to meet the processing needs. For the best price ratio, the best starting point is to use the universal soft PVC plasticizer DINP.
The soft PVC plasticizer, DINP, has been used safely for more than 40 years in the application and production of different products. When the formula designer considers the use of two substituted benzoic acid esters, this choice is usually limited to the special market application, because so far, a real non ortho benzene two formic acid has not been developed as a universal plasticizer substitute.
A mixture of a variety of substituted phthalate two formates may begin to approach performance targets, but they usually greatly increase the cost of the final product. Therefore, the real price of soft PVC products containing non o-phthalic acid ester plasticizers will be more expensive and some product properties will be reduced.
Although DINP is currently limited in some toys and child care products, DINP has been experimentation and research in various applications. The conclusion is that it can be used safely in all applications.
The European Union conducted a 10 year risk assessment of the DINP and concluded that the use of DINP in all current applications, including toys, was not risky.
The consumer product safety committee (CPSC) has made several reviews on the safety of DINP in vinyl toys. Their conclusion is that children's contact with DINP is not risky. In addition, DINP is not PBT (persistent, bioaccumulative and toxic) substances: it is not included in the list of known or suspected carcinogens by the US Environmental Protection Agency (EPA) or the European Union. It's not a EPA dangerous substance.
DINP is not included in reproductive toxicity or developmental toxicity, so it is not required to attach the corresponding label. In fact, it is reported that DINP has been studied more than 200 times and is one of the most fully tested substances in the world. In contrast, any other extended substituted phthalic acid esters have only been studied less than 40 times. In the development of most soft PVC products, DINP will continue to serve as a safe and economic starting point for formula designers.
An ideal plasticizer should have the following properties: (1) have good compatibility with the resin; (2) high plasticizing efficiency; (3) on thermal stability; (4) low volatility; (5) small mobility; (6) water, oil and organic solvent extraction (; 7) low temperature well; (8) flame retardant; (9) good insulation; (10) a colorless, tasteless, non-toxic; (11) fungal resistance; (12) contamination resistance; (13) plastisol viscosity and good stability; (14) price.
Two octyl terephthalate (plasticizer DOTP) raw materials are generally synthesized from the process route of terephthalic acid or two methyl terephthalate as raw material.

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.
When calcium carbonate and other fillers are added to the formula, the physical properties of the product, such as hardness, tensile strength and low temperature flexibility, will be changed. For example, in the range of about 0~80 fillers, the hardness of every 10 CaCO 3 increased by less than 1 shore A hardness units. Under the low filler level, the effect was very small, while the influence degree increased under the high filler level.
Therefore, in order to maintain a constant hardness, in this case, each adding calcium carbonate should be increased by about 10 copies of the 1 DINP. Keep in mind that the increase in the number of low fillers (< 20) is smaller, but a little increase in the number of high fillers (> 50 copies) is needed.
When developing a soft polyvinyl chloride (PVC) formulation, whether the developed product can meet customer's performance and cost depends largely on the choice of suitable plasticizer system.
In all raw material components, plasticizers will have the greatest impact on the final performance of the product. This study will discuss the procedures involved in selecting plasticizers, starting with general plasticizers, then considering alternatives to o-benzoic acid two and other plasticizers.
When developing a new soft polyvinyl chloride (PVC) product, once the target performance characteristics are determined, the two important decisions to be made may be "which plasticizer should be used" and "how many plasticizers should be used".
Generally speaking, these decisions are not complicated. When choosing plasticizers, the usual way is to consider the raw materials that the current production units are using. Then a relatively simple soft PVC formula is gradually formed through a series of experiments and formulation adjustment process.
As other additives and fillers are added to the formula, the number of applied plasticizers may need to be adjusted slightly. The formula is likely to be further adjusted after performance optimization, management level validation, trial production and final cost reduction.
