Preferred Plastics for the Underwater Seismology Industry
The following plastics are frequently used in the Underwater Seismology Industry:
- Celazole®
- PEEK
- Rexolite®
- Ryton®
- Ultem®
Acetal
Semi-crystalline material with extremely low wear and good rigidity, toughness, and dimensional stability. It has low moisture absorption and is easy to machine.
Celazole®
Excellent dimensional stability and strength at the highest sustained temperatures.
PEEK
Semi-crystalline material that provides exceptionally high temperature performance with good wear and friction properties. Easily machined, formed, and welded, it is maintenance-free and wipes clean. Provides design versatility with excellent dimensional stability, has good chemical resistance, and won’t degrade with exposure to water or steam.
Rexolite®
Cross-linked polystyrene with unusually stable electrical properties at high frequencies.
Ryton® PPS
Exceptional chemical resistance, compressive strength, and heat dissipation.
Ultem
Good dielectric properties, dimensional stability, and low thermal expansion.
