Cable wrap

This spirally cut cable wrap for use in enclosed environments is self-extinguishing and does not produce toxic or irritating byproducts when exposed to an open flame. It is available in three materials that will not support combustion: Teflon(R), which operates from -450 to 500F; Rulan, a polyethylene offered in white and black; and Nylon. The wrap is recommended for use where the possibility of fire exists, and is available in sizes from 1/8 to 1 inch OD.

Aluminum alloy

Alloy 7068 was formulated in response to industry requests for a higher strength aluminum alloy with comparable corrosion resistance to 7075 in the T6511 temper. Possible applications exist in aerospace and automotive (valve body and connecting rod applications), and recreational products. Melting range is 890 to 1,175F.

Thermally conductive epoxy

Epoxy 50-3170 is a two-component room temperature curing potting and encapsulating system. Formulated to provide efficient thermal transfer and low stress on electronic components, it cures to a rubber-like consistency and can be used as an adhesive or potting compound for power supplies, coils, glass diodes, and other delicate components. This is also a repairable system. Fresh resin will bond to itself.

Teflon-lined valve

The butterfly valve is used with liquid chloroprene at -18C. It is a 4-inch Gar-Seal(TM)unit, and has reportedly served eight times as long as similar valves lined with conventional PTFE in service with a monomer fluid. Some fluids can wash away lubricants used with metal valves, but due to the chemical and solvent resistance and inherent lubricity of Teflon NXT, no added lubrication is needed. Valves range in size from 2 to 42 inches.

Thermoplastic

PEEK(TM)polymer is formulated to allow the design of complex, injection molded components which can be consistently mass-produced without the need for assembly or post-treatment. Complying with 3-A Sanitary Standards, possible applications include replacing glass, stainless steel, and metal in food processing applications. It can sustain a continuous operating temperature of 500F and is available in powder, pellets, monofilaments for fiber or woven fabrics, and film.
