Wire and cable coverings

The polyetherimide—polysdoxane multiblock copolymers are relatively hard (about 70 on the Shore D scale). Their main appHcation is flame-resistant wire and cable covering (24), where they combine very low flammabiUty with a low level of toxic products in the smoke. This unusual and vital combination of properties justifies their relatively high price, about 37/kg, at a specific gravity of about 1.2. 

TPOs are insulating and are used for low-tension wire and cable covering. Special grades are antistatic or conductive. 

Cable tray fires have resulted from the accumulation of process leakage, residues or combustible dusts or debris on top of cable trays with densely packed wires and cables. Covering shields above cable trays have been used to minimize such accumulations however, such shields should be used with caution as they can limit air circulation and increase cable and wire temperatures in densely loaded trays particularly those carrying power cables. Covering shields may also block fixed fire protection water spray or manually applied firefighting water spray from reaching the cables.

This polymer has outstanding extrusion characteristics, low water absorption, low ash and good electrical properties. As a result, it is useful in such diverse applications as wire and cable coverings, show soles, floor tiles, etc. 

Worldwide consumption of plasticizers is estimated at 3.5 x 106 t (31), and is of the order of 1 million tons in Western Europe (Fig. 7 Table 4). The distribution of plasticizers into various applications is as follows 27%, wire and cable covering 23%, extrusion/proffle 17%, film and sheet 13%, coated fabrics 12%, wall covering and 8%, undersealing/coating. 

Wire and cable covers (in steel mills and nuclear power plants)... 

CSPE have excellent combinations of properties that include total resistance to ozone excellent resistance to abrasion, weather resistance even in light colors, heat, flame, oxidizing chemical, solvents, crack growth, and dielectric properties. Also provide low moisture absorption, resistance to oil similar to neoprene, low temperature flexibility is fair at -40C (-40F), low gas permeability for an elastomer and good adhesion to substrates. Can be made into a wide range of colors. Use includes hoses, roll covers, tank liners, wire and cable covers, footware, and building products (flash, sealing, etc.). 

Other than packaging, collectible items are automobile, light truck and large appliance shredded residue carpets wire and cable coverings and tailings— plastic containing streams recoverable from MSWs. 

USE Rubbar substitutes, electric wire and cable-coverings, pliable thin sheeting, film finishes for textiles, non-flammable upholstery, raincoats, tubing, belting, gaskets, shoe soles. 

Plastics have played critical roles in every aspect of the ongoing revolution in electronics [38-41]. They are now found in everything from computer housings and floppy discs to encapsulants and connectors. The wide range of electrical and electronic applications of polymers includes wire and cable coverings, housing adhesives, printed circuit boards and insulators (Table 7.1). 

Non-stick cookware, water- and bacteria- repellent textiles, wire and cable covers, corrosion-resistant linings for pipes and valves, seals and gaskets, skis. 

Profile extrusion consumes huge volumes of POs for water and gas pipe and wire and cable coverings and insulation. Again, this is another "hidden" use of POs. 

Markets for elertronic consumer products, motor vehides, and textiles remain the most prominent for processors of FR plastic compounds, according to year 2007 and 2008 market surveys. In terms of volume FR use in PP and PE surpasses the volumes used in all noncommodity polymers, and it also exceeds (and is growing faster than) FR use in PVC as weU. This stems from POs use for wire and cable coverings, electrical/elertronic devices, stadium seating, films and fibers, and various construction applications—particularly in market sectors that have seen increasingly more rigorous fire codes [5-1, 5-2, 5-3).
