Plastic Temperature Resistance Performance Parameter Table
Plastics, as indispensable materials in modern industrial production and daily life, are applied in numerous fields such as electronics and electrical appliances, automobile manufacturing, food packaging, aerospace, and more. The thermal resistance property, as the core key indicator of plastic materials, directly determines the applicable environment, service life, and safety and reliability of the products - minor deviations may affect the stability of product functions, while severe deviations may lead to safety hazards. Therefore, accurately grasping the thermal resistance parameters of different plastics is an important prerequisite for material selection, product design, and production processing.

The following is a summary of the core parameters of plastic thermal resistance performance, covering three key indicators: continuous use temperature, heat distortion temperature, and Vicat softening temperature. Core application scenarios are also marked for intuitive comparison and reference:
| Plastic Name | Continuous Use Temperature (℃) | Heat Deflection Temperature (1.82MPa, ℃) | Vicat Softening Temperature (℃) | Core Application Scenarios |
|---|---|---|---|---|
| Polyethylene (PE) | 60-80 | 40-50 | 100-110 | Food packaging, low-pressure pipelines |
| Polypropylene (PP) | 80-100 | 55-65 | 140-150 | Home appliance shells, automotive parts |
| Acrylonitrile Butadiene Styrene (ABS) | 70-90 | 80-95 | 95-110 | Electronic and electrical enclosures, toys |
| Polycarbonate (PC) | 120-130 | 130-140 | 150-160 | Optical components, bulletproof glass |
| Nylon 6 (PA6) | 80-100 | 60-70 | 180-190 | Gears, bearings, automotive interiors |
| Nylon 66 (PA66) | 100-120 | 75-85 | 210-220 | High-strength mechanical parts, textile fibers |
| Polyoxymethylene (POM) | 80-100 | 120-130 | 150-160 | Precision gears, valve components |
| Polyethylene Terephthalate (PET) | 60-80 | 70-80 | 220-230 | Beverage bottles, electronic component skeletons |
| Polyphenylene Sulfide (PPS) | 200-240 | 260-280 | 280-290 | High-temperature electrical appliances, automotive engine parts |
| Polyether Ether Ketone (PEEK) | 240-260 | 310-320 | 340-350 | Aerospace components, medical equipment |
The thermal resistance performance parameters of plastics are the core basis for material selection. The requirements for thermal resistance indicators vary significantly in different scenarios - daily food packaging needs to focus on basic thermal stability, while components of automotive engines under high-temperature conditions and aerospace equipment require the use of special high-temperature-resistant plastics such as PPS and PEEK.
