Polyvinyl chloride resin plasticizer - ZhangJia Gang YaRui
Polyvinyl chloride resin plasticizer PVC plasticizer in PVC resin, with larger proportion, the more soft plastic products: when PVC plasticizer content is less than 5%, plastic products for hard PVC resin; when the plasticizer content in 15% ~ 25%, plastic products for the semi hard; when the amount is greater than 25% plastic products, soft PVC resin; plasticizer dosage is 5% to 15% will
PVC (polyvinyl chloride) plasticizer - ZhangJia Gang YaRui
The plasticizing mechanism of PVC (polyvinyl chloride) plasticizer. Plasticizer modified PVC has two main functions: one is to reduce the melting temperature and melt viscosity of PVC, thereby reducing its processing temperature; the other is to give PVC products softness, elasticity and low temperature resistance.

Plasticizer for PVC resin - ZhangJia Gang YaRui Chemical Co. Plasticizer for PVC resin Since China entered the twenty-first Century, the technology of making fine chemicals has changed rapidly. PVC plasticizer for the renewal is a thousand li a day.
Polyvinyl Chloride Resins (PVC) - The Chemical Company
Polyvinyl Chloride (PVC) is one of the most widely produced thermoplastic polymers in the world after polyethylene and polypropylene. Without the additions of plasticizers, PVC is a naturally white, brittle plastic. Its most common use is in the construction industry, but it is also used to manufacture signs, in healthcare applications, and as a fiber for clothing.
plasticizer good compatibility with pvc resin | Provide water
Plasticizer for PVC resin - ZhangJia Gang YaRui Chemical Co . Soluble in hydrocarbons, ketones, esters, alcohols, ethanol, ethyl ether, mineral oil and other organic solvents, the ester content of 99%, 195 - 200 flash point: the product is one of the most widely used polyvinyl chloride nontoxic plasticizer and stabilizer of good compatibility
- Why does polyvinyl chloride need a plasticizer?
- It is widely acknowledged that the presence of dipole–dipole interactions among polyvinyl chloride molecules contributes to the inherent rigidity and brittleness of unmodified PVC products. Consequently, the incorporation of a significant amount of plasticizer is often necessary to disrupt the intermolecular interactions between polymer chains .
- Are flexible poly (vinyl chloride) plasticizers flammable?
- Nevertheless, the combustibility of flexible poly (vinyl chloride) (PVC) products containing high content plasticizers is frequently disregarded. The development of PVC functional plasticizers requires careful consideration of a good balance between flame retardancy, migration resistance and plasticity through molecular structure design.
- Which PVC plasticizer is best?
- The plasticizer with good plasticity, flame retardancy and migration resistance. VA8-P plasticized PVC exhibits good plasticity at low temperature. VA8-P plasticized PVC obtains the UL-94 VTM-0 grade, superior to DOP. VA8-P plasticized PVC migrates very little in organic solvents.
- How does a plasticizer affect polar PVC?
- The plasticizer executes solvation effect on the amorphous region of polar PVC, thus reducing the glass transition temperature of the polymer . The tensile modulus of the blend is consequently reduced, thereby enhancing the flexibility of the PVC product.
- What is Plastisol PVC resin?
- Plastisol PVC resin is a type of wet-mixed PVC resin that is formed into a useful shape and gelled with heat and fused by further heating, then cooled. In the production process, it is mixed with plasticizers and other formulating ingredients into dispersions of resin/solids in the liquid components of the formulation, which is known as a plastisol.
- Is pvc-p3 a biobased plasticizer?
- In cone calorimeter tests, VA8-P plasticized PVC showed excellent heat barrier effect. Additionally, PVC-P3 reached the UL-94 VTM-0 level in the vertical burning test. Its flame-retardant mode of action was also verified by TGA–FTIR analysis. A functional biobased plasticizer with excellent comprehensive properties has been synthesized.
