Rhenogran SF DPTT-40 Dipentamethylene thiuram tetrasulphide Rhein Chemie Catalysts / Accelerators / Vulcanizing agents >> Thiuram sulfide Rubber - Elastomer (Chloroprene, Butyl …) SEALANT Rhenogran® SF DPTT-40 Ultra accelerator for the vulcanization of natural and synthetic rubber and vulcanizing agent for vulcanization without elemental sulphur and low-sulphur vulcanization. Particularly suitable for the manufacture of high-quality rubber articles. 40% dipentamethylene- thiuramtetrasulphide 60% polymeric cross-linked material Very rapid vulcanization of natural and synthetic rubber with good processing safety are obtained with Rhenogran SF-DPTT 40. In combination with mercapto and sulphenamide accelerators, Rhenogran acts as an activating secondary accelerator. Even in small quantities, Rhenogran SF DPTT-40 is used in combination with other thiuram accelerators. Vulcanizates with high resistance to ageing are obtained. 0.5 - 5 phr heat resistance rubber articles of all kinds, e.g. hoses, seals, gaiters, especially if based on EPDM and IIR particularly suitable for thin-section articles and very soft compounds compatible with all types of rubber Blend of dipentamethylene thiuram tetrasulphide and polymeric cross-linked material. Used as an ultra accelerator for vulcanization of natural and sythetic rubbers and as vulcanizing agent for vulcanization without elemental sulphur and low-sulphur vulcanization. Provides heat resistance in rubber seals, very rapid vulcanization, very high resistance to ageing and compatibility with all types of rubber. Can be used in combination with mercapto and sulphenamide accelerators, and other thiuram accelerators. Use level: 0.5-5 phr.
