Welcome to inquire! Contact: Zhao Shuang. PVC can be divided into soft PVC and rigid PVC. Hard PVC market which accounts for about two-thirds of soft PVC 1/3. Soft PVC is generally used for surface floors, ceilings and leather, but because of soft PVC containing plasticizer (which is also soft PVC and rigid PVC difference), physical performance is poor (as water pipes need to withstand a certain pressure Shandong PVC profile , soft PVC is not suitable for use), so its use has been limited. Hard PVC plasticizer-free, and therefore easy to shape, good physical properties, and therefore has great development and application value. PVC material production process Qingdao PVC profiles, it is bound to add some additives, such as stabilizers for PVC profiles, plasticizers, etc., if used in all environmental additives, PVC pipe that is also non-toxic and environmentally friendly products and tasteless . PVC is very hard, very poor solubility, only a small number of solvent dissolved in cyclohexanone, dichloroethane and tetrahydrofuran and the like, organic and inorganic acids, alkalis, salts are stable PVC profile material with the use of chemical stability the temperature rises. PVC dissolved in acetone - carbon disulfide or acetone - benzene mixed solvent for dry spinning or wet spinning from fiber, called polyvinyl chloride, with flame retardant, acid, anti-microbial, wear, environmentally friendly features and has good thermal resistance and elasticity.
