Product Specifications
| Material | Features |
| RENY - Glassfiber Reinforced Polyamide MXD6 (Glassfiber Reinforced Polyamide MXD) | RENY is based on polyamide MXD6 and is also a crystalline engineered plastic reinforced with 50% glass fiber. It has the highest strength and elasticity among engineered plastics, and excels in both oil and heat resistance. Thus, it is used as an alternative to metal. |
| PPS - Polyphenylenesulfide (Polyphenylenesulfide) | PPS is a crystalline super engineered plastic. It has excellent heat resistance, and does not deteriorate in physical properties even when it is used for long durations in high temperature atmosphere. It excels in chemical resistance, mechanical characteristics, electrical properties and dimensional stability. |
| PEEK - Polyetheretherketone (Polyetheretherketone) | PEEK is semicrystalline super engineered plastic with the highest performance. It has the highest chemical resistance among all engineered plastics. The only generally used chemical that can dissolve PEEK is concentrated sulfuric acid. PEEK also excels in heat resistance, abrasion resistance, flame resistance and hydrolysis resistance. |
