Tape, plastic insulating

Complete the assembly of the electroplating cell by attaching the platinum anode with plastic insulation tape. Position the platinum wire anode about 0.5 cm from the stainless steel disc (cathode). 

In the past, there were fewer accidents because buried cables were better protected. Most of the supply authorities used paper-insulated, lead-sheathed, single-wire or steel-tape armoured and served cables and very often protected them with cable tiles. For economic reasons cable tiles are seldom used now and many of the mains laid in recent years are unarmoured CNE cables with plastic insulation and sheathing, such as PVC and cross-linked polyethylene (XLPE). The outer concentric conductor, which is the earthed neutral, is copper or aluminium tape and consequently more vulnerable to damage than a steel-wire-armoured cable. Every year more new mains cables of this type are laid so the resultant hazard to excavators is growing and more accidents can be expected to occur unless the construction industry becomes more effective at taking precautions against striking buried cables. 

PSAs are often supplied to the final consumer coated onto a substrate such as cellophane tape or insulating tapes based on plasticized PVC film. These consist of the backing film, a primer or key coat, and the adhesive. If the product is to be rolled up in tape form, a release coat may be applied to the back of the film to reduce unwind tension when the tape is applied otherwise it is omitted. The adhesive, generally of the types discussed here, is usually applied from an organic solvent. Aqueous... 

Tapes are flexible substrates (paper, plastic films) coated with PSAs (20-100 g dry m ) and wound up to a roll. Examples are packaging tapes, double-sided adhesive tapes, masking tapes, medical tapes, electrical insulation tapes, office and household tapes. 

Fig. 1.29.2. Measurement of the electrical resistance as in Fig. 1.29.1. However the wall of the vial is insulated by a plastic tape up to the filling height of the product. Therefore the heat is mostly removed through the bottom of the vial (from [1.102]).

Uses of EtCell include films, adhesive, flexible lacquers, varnishes-, plastics, electrical insulators, moulding powders, jelled expls such as used in Bangalore Torpedo (See Vol 2, pp B16 ff), inhibitor tape for rockets and proximity fuzes (Refs 8 10)...

These form a small group which have limited uses for specialized purposes. Asbestos fibre can be spun and made into fireproof fabrics or protective clothing. Fibrous glass is made in substantial and increasing quantities and it is used for insulation tape, industrial filter cloths, and for many other purposes when bonded with polystyrene or other plastic substances.
