Plastic Applications in the Underwater Seismology Industry
PMI provides machined plastics for use in a variety of seismic applications. Combining high strength, exceptional corrosion resistance, and insulating properties, plastic materials are ideal for underwater components and protective equipment. Dimensionally stable with high acoustic efficiency, plastics will not interfere with electronic or mechanical signal transmissions.
Plastics maintain their dimensional and chemical stability under severe conditions. Resistance to heat, steam, saltwater, and chemicals makes many plastics ideal for underwater equipment seals, connectors, insulators, and electrical components.
Bearing and Wear Components
Plastics can provide low friction, dimensional stability with the wide temperature range and low thermal expansion required for bearings, wear pads, thrust and rotary slides, gears, container liners, and other impact-resistant components.
Many plastic materials provide exceptional dimensional stability and excellent sound transmission characteristics, making them well-suited for microwave, radar, and other high-frequency applications.
