Characteristics of plastics
Plastic is a kind of organic compound with high molecular weight, generally in the solid form of synthetic resin or modified natural resin, under the action of heat and pressure can flow, form a certain shape. Type of material. In general, it also includes a considerable amount of plasticizers, stabilizers, fillers, reinforcing materials and other adjuvants. www.handern.com
There are several hundred thousand known organic compounds, most of which have molecular weights below 500. In general, molecular weight above 10000 is called high molecular compounds, less than 1000 is called low molecular compounds. However, the molecular weight of phenolic resin, urea formaldehyde and other resins is only 160~300. Only in the presence of curing agent, the thermosetting plastics with very large molecular weight can be formed after crosslinking under the action of heating and pressure. Compared with low molecular compounds, the difference in chemical and physical properties is great.
The processing, physical and chemical properties of plastics are also important features of concern to plastic workers and users. www.handern.com
To sum up, plastics have the disadvantages:
(1) easy to shape, high degree of freedom design;
(2) Easy to color, can be made with a sense of metal, wood, marble and pearl color effect;
(3) after processing can get beautiful products;
(4) From transparent to opaque, from hard to soft, from solid solid to soft, foaming body and other properties of materials;
(5) Materials can be made to any shape (film, board, sheet, foaming body, products, extruded profile, fiber, etc.);
(6)Lighter than other industrial materials (PP relative density is 0.9; PTFE, the heaviest, is only 2.2);
(7)Excellent electrical performance (including high frequency, low frequency insulation and conductive or semiconductor);
(8) Low heat conductivity, no cold sense of metal;
(9) good water resistance, no rust, no corrosion: no matter in large or small quantities, the energy consumption is lower than that of other materials.
(1) Easy to compound and bond with other materials; (2) excellent chemical resistance. www.handern.com
