Plastic material and process

Introduction To Plastic Material And Process

Thermotting Plastics And Thermoplastics

keep bleedingPlastic is a monomer as raw material, by polyaddition or polycondensation polymerization of macromolecules, commonly known as plastic or resin, can be freely changed body composition and style, from a synthetic resin and a filler, plasticizers, stabilizers, lubricants, color materials and other additives.

Properties of the plastic

Most plastic is light, chemical stability, will not rust

Good impact resistance

Has good transparency and abrasion resistance

Insulation, low thermal conductivity

General formability, good color, low processing costs

Most plastics poor heat resistance, thermal expansion, and easy burning

Dimensional stability is poor, easily deformed

Most plastics poor low temperature resistance, low temperature brittle

Easy to aging

Some plastic soluble in solvents

Common plastic summary

Polyethylene terephthalate

Polyethylene terephthalate (sometimes written poly (ethylene terephthalate)), commonly abbreviated PET, PETE, or the obsolete PETE or PET-P, is the most common thermoplastic polymer resin of the polyester family and is ud in fibers for clothing, containers for liquids and foods, thermoforming for manufacturing, and in combination with glass fiber for engineering resins.
