| | | | | | | | | | | | | | | | | | | | | | | | | PEEK 9cdl drill Jcdl Components PEEK is a tough high temperature engineered thermoplastic offering broad chemical resistance, excellent recovery from deformation, a high degree of dimensional stability, and exceptional resistance to hydrolysis. PEEK has outstanding abrasion resistance and is not sensitive to dynamic fatigue. | | | | | | | | | | G2000 PEEK Chemical Since G2000 PEEK is a virgin crystalline polymer, its resistance to chemical attack is excellent. G2000 PEEK is recommended for most environments other than strong oxidizers. It is compatible with numerous acids, bases, and aliphatic and aromatic hydrocarbons. | | G3000 PEEK G3000 PEEK combines the basic properties of the G2000 PEEK with that of carbon graphite and PTFE fillers, yielding a seating material with greater stability at higher temperatures and significantly reduced seating torque. Due to its filled content, G3000 PEEK is an excellent choice for high temperature applications, having a maximum temperature capability of 550°F (288°C).

This resistance is maintained in both acid and alkali media. | | | | | | | | | | | | | | » Rockwell "D"Scale | | | | | | | | | | 7 | | | | | | | | | | | | | | | | | | | | | | | | |
