1. Chemical Resistance

PVC, often known as polyvinyl chloride, is the third most frequently produced synthetic polymer. It is a chlorinated hydrocarbon produced commercially using the process of free radical polymerization of vinyl chloride monomer (CH2=CHCl).


PVC is the material of preference in the majority of applications because it is more cost-effective and easier to process than LDPE and HDPE. It also provides a number of additional advantages, including as strong insulating qualities, abrasion resistance, and superior product transparency.


K-value, a measure of molecular weight and degree of polymerization, is used to categorize resins. The most common resins have a medium K-value because they provide a compromise between processability and mechanical characteristics.


Although more difficult to produce, higher K-value resins have better mechanical qualities. They may also cost more, however they are frequently employed in specific applications. Battery separator resins and blending resins are a couple of these. Typically, the lower K-value resins have less plasticizer per unit volume than the grades with higher K values.

2. Water Resistance

Resin K65-67 PVC One of the most popular synthetic polymers for use in numerous industrial fields is China Manufacturer. Excellent fire resistance, abrasion resistance, chemical corrosion resistance, product clarity, electrical insulation, and comparatively simple production qualities are just a few of its outstanding list of attributes.


Suspension and Paste grade PVC resin are the two primary varieties that are offered. The former is created using water-suspended drops of vinyl chloride monomer, but the latter also contains emulsifying and polymerization catalysts.


Suspension grade is the most widely used variety; it is very porous and can absorb plasticizers more quickly than less porous forms. Additionally, they cost less than paste-grade PVC.


The second most widely used type of PVC resin is called pvc paste grade, and it is made of Plastisols with small particle sizes that have been blasted dry using a mixture of emulsifying agents and catalysts. In comparison to suspension or bulk polymerized grades of resin, this results in a more compact PVC compound that is significantly less expensive to create.

3. Light Resistance

PVC is a thermoplastic substance that can be blended with different amounts of plasticizers, fillers, stabilizers, lubricants, and colors. These substances can be utilized to create a variety of qualities, such as electrical insulation, chemical resistance, impact strength, and flame retardancy.


PVC's susceptibility to both light and heat degradation is a serious issue because the molecule is so fragile. Light exposure causes the polymer chains to disintegrate, releasing caustic and explosive hydrochloric acid gas.


Stabilizer chemicals, which help the pvc polymer withstand changes in temperature and sunshine, can reduce this process, though. These substances also provide extra defense against corrosive and abrasive particles. They could also aid in enhancing the finished item's tensile strength. These additives can be included during the blending process, and calcium carbonate is frequently mixed in as well to cut costs. For best outcomes, care should be taken to choose the grade and addition level most appropriately.

4. Heat Resistance
