What Are the Engineering Applications of Plastic?
When people ask “What are the engineering applications of plastics and polymers?”, they often mean engineering-grade plastics used in demanding environments.
Plastics like ABS, POM, PC, PA, and PEEK are essential for manufacturing mechanical components that must endure stress, heat, and wear—such as gears, brackets, switch housings, and enclosures.
| Sector | Plastic Type | Typical Applications |
|---|---|---|
| Automotive | ABS, PA6 | Cable holders, dashboards, clips |
| Industrial | POM, PTFE | Gears, bushings, alignment tools |
| Aerospace | PEI, PAI | Panel structures, fluid seals |
| Electronics | PC, ABS | Enclosures, display bezels, mounts |
At Prime, we specialize in custom plastic components for engineering use, from tight-tolerance CNC bushings to shock-resistant cable guides—all produced under ISO-certified systems.
What Are the Engineering Applications of Polymers?
If you're exploring “What are the engineering applications of plastics and polymers?”, polymers represent the broader family, including both thermoplastics and thermosets.
Polymers are used in everything from composite aircraft skins to chemical seals and bio-safe implants. Their mechanical behavior under heat, pressure, and fatigue make them ideal for high-stress systems.
| Field | Application | Polymer Material |
|---|---|---|
| Structural Design | Sandwich cores, beams | CFRP, PU, epoxy |
| Biomedical Engineering | Tubes, implants, devices | PLA, Silicone |
| Electrical Systems | PCB substrates, cables | PVC, PI, PET |
| Thermal Control | Heat shields, spacers | PEEK, PPS |
Our engineers at Prime recently supported a solar firm by developing high-temp polymer panels that resist UV degradation and maintain rigidity in +60°C desert environments.
