Polar synthetic rubber blends applications

The thermal properties of NR based polar synthetic rubber blends is expected to affect the application range of these vulcanizates. Degradation, glass transition and crystallization temperatures determine the service conditions of each blend. Additionally, the existence of single or multiple shifted or not glass transition temperatures of each blend supplies evidence for the miscibility of the components involved. " Nevertheless, in many cases further analysis might be required to determine miscibility. [Pg.249]

Latex blending of NR with polar synthetic rubbers presents several mixing advantages e.g. eco-friendly dispersion medium, fine particle dispersion, etc), but for other applications does not provide any cost advantage since coagulation, removal of water and drying are cost-intensive processes. ...

Natural rubber/chlorosulfonated polyethylene rubber blends also exhibited immiscibility. Chlorosulfonated polyethylene rubber is the synthetic rubber used for applications in electric cables, hoses for liquid chemicals, waterproof cloths, floor tiles, and oil-resistant seals. It is chosen to blend with natural rubber to improve the resistance of natural rubber to ozone, oil, heat, flame and non-polar chemicals. This is due to the effect of the polarity of the chlorine groups in the chlorosulfonated polyethylene rubber. The tensile strength, elongation at break, and tear strength of these blends decreased with the increasing chlorosulfonated polyethylene rubber contents. In addition, the compatible natural rubber/chlorosulfonated polyethylene rubber blends were improved by adding the epoxidized natural rubber (Epoxyprene 25) as a... [Pg.514]

Solvents have been classified on various arbitrary bases (1) boiling point, (2) evaporation rate, (3) polarity, (4) industrial applications, (5) chemical composition, (6) proton donor and proton acceptor relationships, and (7) behavior toward a dye, Magdala Red, Thus on the basis of industrial application one can classify solvents as those for (1) acctyl-ccliulosc, (2) pyroxylin, 13) resins and lubber, (4) cellulose ether, (5) chlorinated rubber, (6) synthetic resins, and (7) solvents and blending agents for cellulose ester lacquers. Solvents classified according to chemical composition are noted below. [Pg.1524]
