| name | unit/(kg/cm3) | material properties | usage | shrink/% |
| ABS | 1.02~1.16 | Impact resistance, high tensile strength, and rigidity, these properties will not change at low temperatures. In addition, it has considerable heat resistance, chemical resistance, stable size, easy processing, and cheap materials. | Electrical parts, radio casings, vacuum cleaner parts, etc. | 0.3~0.8 |
| PS | 1.04~1.06 | Colorless and transparent, hard and slightly brittle, good water resistance, excellent electrical insulation, not infringed by strong acids and alkalis, but lacks resistance to organic solvents and poor heat resistance. In addition, it is very formable and freely colorable, but slightly brittle. | Tableware, commodity containers, toys, fruit bowls, toothbrushes, soap boxes, etc. | 0.2~1.0 |
| PE | 0.91~0.93 | Milky white translucent or opaque, lighter than water, soft, water resistance, electrical insulation, and acid resistance are very good. It is stable in most medicines and easy to shape. However, its heat resistance is not good, and its chemical properties are inactive, resulting in poor printing and bonding. | Various bottles, fishing nets, thick ropes, telephone wires, cutting boards, trash cans, film, etc. | 0.5~2.5 |
| PC | 1.02 | Colorless to light yellow transparent, high tensile strength and impact resistance. These properties are comparable to metallic materials and do not change much with temperature. anti-UV. However, it needs 220~230°C to soften and melt, and the viscosity is also high, so it is difficult to form and requires high temperature and high pressure. | Safety helmets and various mechanical parts, gauge casings, electrical machinery parts | 0.4~0.7 |
| PA | 1.13~1.15 | Tough, oily surface and wear-resistant, strong shock absorption, heat-resistant, cold-resistant, can be used stably from high temperature to low temperature, resistant to chemicals, generally easy to absorb moisture, and the size and strength will change greatly due to this. | Often dedicated to radios, copiers, skate soles, brush bristles, combs, gun casings, etc. | 0.6~2.5 |
| PP | 0.9~0.91 | The heat resistance and strength are very high, and the density is only 0.9~0.92. It is the lightest plastic. Good transparency, high tensile strength, and surface hardness, but not impact resistant at low temperatures, not UV resistant. | Shells of electrochemical devices, fishing nets, thick ropes, buckets, food utensils, pipes, filter cloths, film, etc. | 1.0~2.5 |
| PMMA | 1.17~1.20 | Like PS material, it is a plastic material with the best transparency, and good weather resistance, and is difficult to cut. It can be plate-shaped plexiglass, or it can be heated and bent into a curved surface, and it can be colored into gorgeous colors. | Auto parts, lighting covers, optical lenses, dentures, contact lenses, etc. | 0.2~0.8 |
| PVC(soft) | 1.16~1.35 | Strength, electrical insulation, chemical resistance, adding plasticizer will soften, heat resistance is not very good. | Soft PVC can be used as tablecloths, packaging films, handbags, chemical shoes, etc. | 1.5~3.0 |
| PVC(hard) | 1.35~1.45 | Strength, electrical insulation, chemical resistance, adding plasticizer will soften, heat resistance is not very good. | Hard PVC can be used as signboards, electrical parts, chemical-resistant appliances, etc. | 0.6~1.5 |
