Description
Vartube Extruded Tubings are made from polyvinyl chloride (PVC) and its copolymers which, because of the ease with which they combine with a large number of compounding elements, make it possible to produce tubings with a variety of performance characteristics.

There are three types of Vartube, all of which are resistant to oils, alcohol, aliphatic solvents, acids and alkalies as well as to fungus growth and corrosion.

Type SHH: A high heat-resistant, Class 105 tubing recognized by UL for continuous use in 105°C applications and VW-1 Flame lest compliance under File #E69513. Also meets the requirements of, and is on the QPL for, MIL-I-631, Grade c, Classes I and II, Category 1.

Type 120/210: A high-quality, general purpose Class 90 tubing which exhibits an exceptionally wide temperature range from -55°C to 90°C maintaining a high dielectric strength and excellent flexibility over its full thermal span. Meets the requirements of, and is on the QPL for, MIL-I-631, Grades a and b, Classes l and II, Category 1.

Type 302/203: A Class 85 tubing able to withstand temperatures as low as -70°C.Its low- temperature characteristics exhibit unusual flexibility and high cut-through resistance with maintenance of dielectric strength. The upper thermal limit of 85°C is outstanding for this type of tubing. Meets the requirements of MIL-l -7444, Class 1, Types I and Ill.

Applications
Type SHH: Widely used on transformer, motor and coil lead wires. Also finds applications in electronic apparatus and in consumer goods such as toys, blenders, food machines, outboard motors, lawn care equipment, lighting equipment, motorcycles, etc. May also be used for vacuum or pressure hoses and transfer of compatible liquids.

Type 120/210: Used in appliances, electric motors, commercial and military aircraft, automotive components and a host of other installations. Its low temperature characteristics make it particularly useful in airborne equipment, electrical harnesses and snow machines.

Type 302/203: Recommended for cable and conduit installations and harnessing, especially where very low temperatures are to be encountered such as airborne devices, aircraft, missiles and snow machine wiring harness jackets.
