The M-2 Plastic THINSULATOR® pipe insulator is a high-density, polyethylene product, injection molded to provide low cost insulators of highest quality. This high-density polyethylene gives the M-2 such strength that it is made more compact than other insulators.
The flexible M-2 Plastic THINSULATOR conforms to the pipe for uniform coating loading. Its low friction coefficient enables it to slide easily inside the casing. Electrical properties include its dielectric strength: short time, 1/8? thickness, 500 volts/.001 inches (D149-64). The casing insulator has robust mechanical properties. The tensile strength is rated at 4,000 psi at 20 inches/minute. Elongation is
25% at 20 inches/minute.
It is resistant to impact fracture, with a notched toughness rating of 9 ft. lbs./in. (5 Joules/cm). For best results, do not use above 120°F (50°C).
