Processing & Custom Machining
The brochure presents PSU sheet, rod and machined components as available product forms. For custom PSU parts, technical evaluation should be based on the actual component drawing and service conditions rather than material name alone.
- 2D engineering drawing or 3D model
- Required dimensions and dimensional tolerances
- Material grade and required appearance
- Quantity or annual demand
- Operating temperature and thermal cycling conditions
- Contact chemicals, fluids or cleaning agents
- Steam sterilization or disinfection conditions where applicable
- Mechanical load, wear and dimensional-stability requirements
Anwendungen
| Application Field | Source-Based Application Focus |
| Electrical & electronics | Electrical insulation, structural components and parts requiring stable dielectric performance |
| Automobilindustrie | Components exposed to elevated temperatures and demanding engineering conditions |

Why PSU Is Selected
PSU is suited to applications where heat resistance must be combined with mechanical strength, dimensional stability, hydrolysis resistance and electrical performance. Its resistance to repeated steam exposure and high-energy radiation further broadens its potential use in industrial, electrical, mechanical and hot-water environments.
PSU Selection Guide
| Requirement | Selection Consideration |
| Repeated steam exposure | Consider PSU and confirm the actual steam cycle and grade suitability. |
| Electrical insulation | Evaluate dielectric and insulation requirements together with operating temperature. |
| Dimensional stability | PSU is highlighted for good dimensional stability and creep resistance. |
| Radiation exposure | The brochure highlights resistance to gamma and X-ray radiation; confirm the actual dose and service conditions. |
| Food-contact use | Confirm the exact grade, regulatory documentation and intended food-contact conditions. |
| Machined components | Select rod or sheet according to geometry, machining route and tolerance requirements. |
Temperature Specification Note
The supplied brochure contains more than one temperature-related statement for PSU: the material overview mentions a working range of approximately -100°C to 100°C, while the performance section states long-term use from 100°C to 160°C and identifies a highest continuous air temperature of 150°C. These statements are reproduced as source information and are not reconciled here. For engineering selection, the applicable temperature limit should be confirmed against the exact PSU grade and current technical documentation.
Specification & Certification Note
The technical values and descriptions in this document are based on the supplied Guangdong Zhenghao PEEK product brochure, specifically the PSU material and plate/rod specification pages. Where the brochure indicates food-contact-related inertness or other application suitability, the exact grade and applicable regulatory documentation should be confirmed before commercial or regulated use.
