Plastics chlorine

Coal tar epoxy and plasticized chlorinated rubber laquer coated on mild steel were studied by Scantlebury et al (28). Impedance plots show a gradual decrease in the value of R t and the onset of Warburg-type behavior with increasing Immersion time in 3 weight percent sodium chloride solution. Appearance of an inductive loop when the coal-tar epoxy had a pin-hole was clearly demonstrated.

Chlorine is used to produce many commercially important products. Tremendous amounts of it are used in extractive metallurgy and in chlorinating hydrocarbons to produce a variety of compounds (such as polyvinyl chloride, a plastic). Chlorine is present as CI2, NaClO, Ca(C10)2, or Ca(C10)Cl in household bleaches as well as in bleaches for wood pulp and textiles. Under carefully controlled conditions, CI2 is used to kill bacteria in public water supplies. 

The substances detected included herbicides, such as Alachlor, butachlor, atrazine, cyanazine, propazine, and simazine insecticides, such as chlordane, heptachlor, dield-rin, eldrin, and DDE as a DDT metabolite and industrial organics, which included alkylbenzenes such as toluene, xylenes, ethylbenzene alkanes such as decane through pentadecane naphtalene and methylnaphtalenes alkyl phthalates, used as plasticizers chlorinated methanes and ethanes, especially CHCI3 chlorinated benzenes and chlorinates phenols benzaldehyde dicyclopentadiene, etc. Of these compounds, the hydrocarbons are typical of oil refinery operations, and the chlorinated benzenes and phenols are associated with herbicide and insecticide production.

Several claims have been made for the use of PCL as a plasticizer for other polymers which can then be used as plastic clays for modelHng purposes. Thus, 5-50 parts of PCL are said to plasticize chlorinated polyethylene (25-45 wt % Cl) to produce plastic clays with softening points of 40-60 °C [63, 64]. Similarly,...

Chlorinated rubber is used in topcoats for heavy duty maintenance paints because of its low water permeability. It is also used in tie coats on polyolefin plastics. Chlorinated rubber dehydrochlorinates and requires stabilizers similar to those used with PVC. Some metal salts, especially those of iron, tend to promote degradation of chlorinated rubber and so it degrades when applied over rusty steel. Chlorinated ethylene/vinyl acetate copolymers have been developed that can be used to replace chlorinated rubber in at least some applications (183).

Unvulcanized products based on Hypalon 48 have about a 10 point higher hardness, higher modulus, and lower resUience than one using Hypalon 40 series with the same aromatic oil levels. Aromatic oils are less compatible in Hypalon 48 than in the Hypalon 40 series hence the lowest aniline point grade should be selected to prevent bleeding, or blend with chlorinated paraffin or an ester plasticizer. Chlorinated paraffin or ester plasticizers do not exhibit any difference in properties in the Hypalon 48 compared with Hypalon 40 series compounds.
