Chlorine-sulfonated polyethylene containing 1.5% sulfur and 27% chlorine. Its properties are comparable to those of chlorine-butadiene-rubber CR. Because of the chlorine atoms contained within the chlorine-sulfonyl-group and the lacking of double bonds, dCSMdd is resistant to ozone and features good electrical insulating properties. However it is more expensive than CR.

Usage:

CSM is mostly applied when blended with NR, BR or SBR in order to increase the processing qualities of these materials.

TFB is a thermoplastic fluoroterpolymer, which consists of tetrafluoroethylene (TFE), hexafluoropropylene (HFP) and vinylidenefluoride (VDF). TFB is also known as THV® from Dyneon. The mnemonic makes up by the initial letters of the used monomers. (T for tetrafluoroethylene, H for hexafluoropropylene and V for vinylidenefluoride). TFA is characterised by transparency, flexibility and the ability to form connections with other polymers. It is resistant to multiplicity of chemicals and it is almost impermeable for carbon based motor fuels and aggressive chemicals.

Usage:

• for security glasses
• for flexible panels
• in solar cells
• in fuel systems of automotives
• as lining material for tanks
• as envelope material for special cables
• corrosion protection in the chemical, pharmaceutical and microelectronic industry
• as non-combustible, corrosion protective envelope material in clean rooms
• envelope material in pure water systems

Time needed by a chemical for permeating through a material. An important characteristic, e.g. for gloves, which can be determined. Relevant question for this instance:
How long is a glove usable, before the chemical permeates through the material?

Raw monomeric chloroprene is a colourless fluid. It is insoluble in water but soluble in most organic solvents and has got a tendency towards crystallisation. The polymer is industrially produced by adding HCl to vinylacetylene or directly from butadiene and chlorine whereas nowadays, the latter method is the dominating. (see also: Chloroprene-Rubber, CR)

Usage:

Adhesive agents (cold-processed polymer resins), cables, protective enclosures, conveyor belts (hot-polimerised polychloroprenes)
