1. POLYVINYL CHLORIDE

2. WHAT IS POLYVINYL CHLORIDE
Abbreviated as PVC
The third-most widely produced plastic
Thermoplastic
Pure polyvinyl chloride is white, brittle solid

3. HISTORY
First discovered in 1835 by French chemist, Henri Victor Regnault
Then in 1872 by German chemist, Eugen Baumann

4. CHEMICAL THINGS
PVC is a polymer which is made from monomers called vinyl chloride.
It is formed by the kind of polymerisation called “Addition”
Its IUPAC name is called poly(1-chloroethene)

PROPERTIES
Properties
Melting Point
100 – 260 °C
Resistivity / Insulation
Good

8. MANUFACTURING PROCESS
Extrusion
The shaft (which is called "Screw") in the cylinder is rotated to push resin forward
Resin is melt by heat and kneaded
While it is pushed forward, and then extruded from the outlet dies.

9. MANUFACTURING PROCESS
Thermal
Sheet or film manufactured by the calendaring technology or the extrusion technology is heated to soften.
Air in the metal mold is sucked out to press the melt material at an ambient pressure
This is called "Vacuum Molding", which is used for the production of thin packaging material such as the egg package

10. MANUFACTURING PROCESS
Injection
This is a technology to inject melt resin into the metal mold by pressure
best suitable for production of PVC goods with three-dimensional structure such as sealed containers
