The rubber-producing tree, Ficus elastica (the Indian rubber tree), requires the same substrates for rubber production as other rubber-producing plants, such as Hevea brasiliensis (the Brazilian or Para rubber tree), the major source of commercial natural rubber in the world, and Parthenium argentatum (guayule), a widely studied alternative for natural rubber production currently under commerci...

Abstract Rubber seeds are a by-product of rubber production and rich in oil protein. Upgrading to produce proteins, oils feedstock can generate additional revenue for reduce waste. The present study investigates the effects different pre-treatments extraction methods determine optimal protein from seed kernels. Mechanical expulsion using screw press solvent n-hexane were employed separation. hi...

in some special cases, rubber compounds with high amounts of unsaturated elastomer are recommended with organic sulfur donors instead of mineral sulfurs. in this condition, activated sulfur is produced in situ and curingprocess is facilitated without accelerators. organic sulfur donor compounds have low thermal stability and in the vulcanization temperature produce free and activated sulfurs. t...
