Cable coating

The paper discusses the application of dynamic indentation method and apparatus for the evaluation of viscoelastic properties of polymeric materials. The three-element model of viscoelastic material has been used to calculate the rigidity and the viscosity. Using a measurements of the indentation as a function of a current velocity change on impact with the material under test, the contact force and the displacement diagrams as a function of time are plotted. Experimental results of the testing of polyvinyl chloride cable coating by dynamic indentation method and data of the static tensile test are presented.

Flexible Applications. The mainstay of the lead stabilizers in the United States is in flexible wine and cable coating appHcations. The nonconductive nature of lead stabilizers is unsurpassed by other classes of stabilizers. Rather high levels of stabilizers are necessary for these uses because... 

The aryloxyphosphazene polymers, on the other hand, have been used primarily ia wire and cable coatings and jackets and as fire-resistant, low smoke, closed-ceU foams and sound-barrier sheets. 

Bonding Agents. These materials are generally only used in wire cable coat compounds. They are basically organic complexes of cobalt and cobalt—boron. In wire coat compounds they are used at very low levels of active cobalt to aid in the copper sulfide complex formation that is the primary adherance stmcture. The copper sulfide stmcture builds up at the brass mbber interface through copper in the brass and sulfur from the compound. The dendrites of copper sulfide formed entrap the polymer chains before the compound is vulcanized thus hoi ding the mbber firmly to the wire. 

Triorganotin compounds have also been used experimentally in controUed-release formulations to control the infective snail vector in the debiHtating tropical disease schistosomiasis (biHiarzia) and to control mosquitoes in stagnant ponds (103). As yet, the large-scale use of such methods has Htfle support in the host third world countries where these problems are most severe. Tributyltin chloride has been used to confer rodent-repeUent properties on wine and cable coatings (104). 

High elasticity is also not utilised in the main application of chlorosulphonated polyethylenes, in wire and cable coating, which consume about 40% of output. The combination of heat and oil resistance has led to widespread use as sheathing for nuclear power cables, offshore oil rig cables and in diesel electric locomotives. Other uses include chemical plant hose, spark plug boots and as a base for flexible magnetic strips. 

Neoprene rubber could be used for tire production, but it is expensive. Major uses include cable coatings, mechanical goods, gaskets, conveyor belts, and cables. 

The main use of ethylene-propylene rubber is to produce automotive parts such as gaskets, mechanical goods, wire, and cable coating. It may also be used to produce tires.

CPE has been used successfully in under-the-hood wire and cable-coating applications such as flex cord jackets, heater cords, jackets for industrial cables and radiation crosslink-able speciality cables. 

However, it is possible to crosslink exceptional compounds by high-energy radiation under particular conditions. This method is used, for example, for cable coating and foams. These results are examples only and they cannot be generalized. 

This technique is commonly used for wire and cable coating. 

Also used in wire or cable coatings impregnants in cotton and asbestos braided insulation coating on glass air filter pads, metal mesh to filter air and gas streams (Monsanto, 1960). 

The extrusion process takes unvulcanized rubber and forces it trough a die, which results in long lengths of rubber of a dehnite cross-section. There are two general subdivisions of this technique one extrudes simple products and the other builds products by extruding the mbber onto metal or fabric reinforcement. Products from these techniques include tire tread, cable coating, and rubber hose.
