What is the difference between PVC and nylon?
Want to figure out, PP forum, a lot of PVC film information, there are a lot of PVC film and printing bag to do friends, many of which are in the first line operator, responsible for the technology. There are also PVC particles
First, PVC: chemical name PVC, sub-rigid polyvinyl chloride and soft polyvinyl chloride. High mechanical strength, chemical properties of vinyl chloride (code-named PVC) is a vinyl chloride monomer polymerization from the synthetic polymer. Polyvinyl chloride is a white or light yellow powder resin, the density of about 1.4, chlorine content of 56% to 58%. In the polyvinyl chloride resin by adding different plasticizers and stabilizers, can be made of different rigid polyvinyl chloride and soft polyvinyl chloride.
Polyvinyl chloride itself is a linear polymer, because the attraction between the molecules is very large, combined with each other close and solid, making the polymer chain is not free, so hard texture. When the resin is not added or less (10% or less) plasticizer, get the hard PVC. Hard PVC high density, with acid, alkali and corrosion resistance of the excellent performance, it is often used as chemical equipment, pipe and construction panels, such as flooring, ceiling and so on.
When adding more plasticizer in the resin, you can get soft polyvinyl chloride, plasticizer plus more, the more flexible the plastic. Soft PVC with flexibility, resistance to folding, light, water, oxidation resistance, it is often used to make thin film and wire foreskin and so on. Most of the PVC products in daily life are soft polyvinyl chloride, such as PVC made of leather widely used in clothing, footwear, suitcases, purses and so on.
If you add a blowing agent to the polyvinyl chloride plastic, you can make the foam. It has a light weight, thermal insulation, noise and other excellent performance, widely used in footwear, building materials, ship and aircraft manufacturing and other industries.
