Formulating Nitrite Butadiene Rubber High Density Polyethylene Blends by Using Industrial Blends and Compatibilized Chloroprene Rubber

Finally, once mixing was completed the compounds were kept at room temperature for a minimum of 24 hours and their cure properties were then measured. The respective optimum setting time (t 90) obtained by the rheometer was obtained by compression molding the test sample at 160 ° C. and a pressure of 20 MPa. After curing, the vulcanized sheet was removed from the mold and immediately cooled down under running water to stop further curing. All samples were cured at this temperature and stored in a cool and dark place for 24 hours.

Prachayawarakorn, etc. (2006) The effects of low density polyethylene (LDPE) content, compatibilizer type and rubber tree content on the properties of PVC / LDPE composite blends were investigated. The results of these experiments show that as the LDPE content increases the mechanical properties of the PVC - LDPE blend are gradually decreasing due to insufficient interfacial adhesion. Continuity and compatibility between PVC and LDPE phases including polychlorinated polyethylene (CPE) poly (methyl methacrylate-butyl acrylate) can be improved by three compatibilizers. (PA 20) and poly (ethylene-co-methacrylate). PA 20 was found to be the most suitable compatibilizer for the mixture. The decomposition temperature of PVC in the mixture decreases with PA20 and the amount of wood chips blended

Polybutadiene is synthetic rubber. Polybutadiene rubber is a polymer formed by polymerization of monomer 1,3-butadiene. Polybutadiene has high abrasion resistance and is particularly useful in the manufacture of tires which consume about 70% of the production. An additional 25% is used as an additive to improve the toughness (impact resistance) of plastics such as polystyrene and acrylonitrile butadiene styrene (ABS). In 2012, polybutadiene rubber accounted for about a quarter of synthetic rubber consumption worldwide. It is also used for the manufacture of golf balls, various elastic bodies and electronic parts coated or wrapped to give high resistivity.
