Introduction

Polyvinyl chloride (PVC) is the world's second most common resin. As early as 1835, French chemist Renault discovered that vinyl chloride polymerizes into a white solid under sunlight. In 1914, German and American chemists discovered that organic peroxides could accelerate the polymerization reaction of vinyl chloride. In 1931, the German Farben Chemicalbook Company used emulsion polymerization to industrialize the production of polyvinyl chloride. Emulsion polymerization is to combine vinyl chloride monomer and water, using sodium alkyl sulfonate (surfactant) as an emulsifier to evenly disperse vinyl chloride in the water to form an emulsion, and then use potassium persulfate or ammonium persulfate as an initiator. agent to polymerize vinyl chloride into polyvinyl chloride.

●  Polyvinyl chloride, referred to as PVC, is one of the earliest industrialized plastic varieties. Its current output ranks second only to polyethylene. Polyvinyl chloride has been widely used in industry, agriculture and daily life. Polyvinyl chloride is a polymer compound polymerized from vinyl chloride. There is thermoplasticity. White or light yellow powder. Relative density 1.35~1.40. Chlorine content is 56% to 58%. The melting point is about 70~85℃. Soluble in or swollen by ketones, esters, tetrahydrofuran, and chlorinated hydrocarbons. Has excellent chemical resistance. Thermal stability and light resistance are poor. Hydrogen chloride begins to decompose when the temperature is above 1Chemicalbook or exposed to sunlight for a long time. Stabilizers are required when manufacturing plastics. Excellent electrical insulation and will not burn. Used in making plastics, coatings and synthetic fibers. Depending on the amount of plasticizer added, soft and hard plastics can be produced. The former can be used to make transparent films (such as raincoats, tablecloths, packaging materials, agricultural films, etc.), artificial leather, foam plastics and wire coverings, etc. The latter can be used to make plates, pipes, valves, doors and windows, etc. Use suspension polymerization to obtain powdery resin. Emulsion polymerization is used to obtain paste resin. Can be used to make soft or hard plastics.

●  Its products are used in various fields such as light industry, building materials, agriculture, daily life, packaging, and electricity.

●  Can be used to produce various high-grade insulation materials, agricultural films, artificial leather, plastic shoes, hard pipes, records, welding rods, etc.

●  Used as raw material for polyvinyl chloride plastic products

●  Used to produce U-PVC doors and windows, special profiles and pipes, etc.

●  Used to make perchlorethylene resin, etc.

●  Used in food packaging, water pipes and general PVC products

●  Used for furniture veneers, speaker veneers, blown films, etc.

●  Used for extrusion processing into blood transfusion catheters, drainage bags, drainage catheters, drip buckets, etc. as well as other medical accessories and catheters
