Pakistan Turkey q/320206gad03-2008 Rubber vulcanizing agent Insoluble sulfur can improve the resistance to both fatigue and ageing of all kinds of rubber products. It is used as the best vulcanizing agent for rubber. And it is widely used in the manufacture of the rubber chemistry such as tire, rubber pipe, shoes, cable and wire, insulating
Sulfur is removed from products in the form of acid gas, H2S, which is then sent to the Sulfur Recovery Unit (SRU) to produce elemental sulfur. Gases such as CO2, SO2, and SO3 are found with hydrogen sulfide in the acid gas. The feed to the
US3817952A Branched epdm copolymers and a process
A process for producing a vulcanizable branched elastomeric polymer by mixing an EPDM copolymer with sulfur, a sulfurreleasing compound, or a perioxide, and subsequently heating the resultant mixture. The copolymers of the process have less than about 30% gel, a Wallace plasticity of about 30 to 100, and an inherent viscosity of at least about 2.0 at less than 30% gel.
