Plasticizers epichlorohydrin elastomers

AH of the polyether elastomers, like other vulcanizable elastomers, can be compounded with processing aids, fillers, plasticizers, stabilizers, and vulcanizing agents to make useful mbber products. A typical compounding recipe for epichlorohydrin elastomer is as follows ... 

Epichlorohydrin is usually prepared from propene and is mainly used in the manufacture of glycerol and epoxy resins. It is also used in the manufacture of elastomers, glycidyl ethers, cross-linked food starch, surfactants, plasticizers, dyestuffs, pharmaceutical products, oil emulsifiers, lubricants, and adhesives as a solvent for resins, gums, cellulose, esters, paints, and lacquers and as a stabilizer in chlorine-containing substances such as rubber, pesticide formulations, and solvents. 

Some materials that have achieved importance include EPDM/PP, NBR/PA, PU/PA, SEBS/PA, EPDM/PBT, and epichlorohydrin rubber/PA. Usually, these materials are made more processable through plasticizing oils. Holden (19%) provided trade names of selected compositions, emphasizing those based on hard polymer-elastomer combinations see Table 6.9.
