Insulation material characteristics

Feature One
<1> Chemical Resistance
<2> glossy, partially transparent or translucent
<3> Mostly good insulators
<4> light and strong
<5> Easy to mass produce, cheap
<6> Wide range of uses, multiple functions, easy coloring, high temperature resistance
(7) The effect of storing goods can be damp-proof. Plastics are also divided into general-purpose plastics and engineering plastics, which are mainly defined by the wide range of uses. For example, PE and PP are inexpensive and can be used on various types of machines. . Engineering plastics are more expensive, but the stability of raw materials and physical properties are much better. In general, they have both rigid and tough properties. PVC transparent plastic plate: A high-strength, high-transparent plastic plate produced by the introduction of foreign advanced technology and high-grade imported raw and auxiliary materials.

Feature 2
1 Most plastics are light, chemically stable and will not rust;
2 good impact resistance;
3 has good transparency and wear resistance;
4 good insulation, low thermal conductivity;
5 General moldability, good coloring, low processing cost;
6 Most plastics have poor heat resistance, high thermal expansion rate, and are easy to burn;
7 poor dimensional stability, easy to deform;
8 Most plastics have poor low temperature resistance and become brittle at low temperatures.
9 easy to age;
10 Some plastics are easily dissolved in solvents.

Plastics can be divided into two categories, thermosetting and thermoplastic. The former cannot be reshaped and used, and the latter can be repeatedly produced. There are basically two types of plastic polymer structures: the first is a linear structure, the polymer compound having such a structure is called a linear polymer compound, and the second is a body structure, and the polymer structure having such a structure It is called a bulk polymer compound.

Some polymers have branches, called branched polymers, which are linear structures. Although some polymers have crosslinks between molecules, they are less crosslinked and are called network structures, which are body structures. Two different structures exhibit two opposite properties. The linear structure (including the branched chain structure) polymer has elasticity and plasticity due to the presence of independent molecules. It can be dissolved in a solvent and melted by heating. The hardness and brittleness are small. Due to the absence of independent macromolecules, the bulk-structured polymers have no elasticity and plasticity, do not dissolve and melt, and can only swell and have greater hardness and brittleness. Plastics have both structural macromolecules. Thermoplastics are made of linear macromolecules and thermosetting plastics are made of macromolecules.
