Use
Mode of action: Isogran® IS 90-65 contains approx. 58.5% by weight of a modified polymeric sulphur, which is insoluble in carbon disulphide and other solvents.
Isogran® IS 90-65 is a vulcanizing agent for all natural and synthetic rubber compounds in which sulphur bloom or infiltration of neighbouring layers of compound should be avoided. The use of insoluble sulphur Isogran® IS 90-65 is therefore recommended for all applications that require laying-up, welding, or where good ply-adhesion is essential.
Processing: The thermoplastic, fully compatible polymer binder which is combined with special dispersing agents allows quick absorption and excellent dispersion in the rubber. In this way, optimal activity of the effective substance assured. In order to avoid the insoluble sulphur converting into soluble sulphur Isogran® IS 90-65 should only be added towards the end of the mixing process.
Dosage: Isogran® IS 90-65: 1 – 6 phr
Application: All types of tyres, conveyor belts, re-treading material, assembled hoses, etc.
Packing: 25kg cartons
Storage stability: In original closed containers under cool and dry conditions max. 1 year. At storage contact with destabilizing substances should be avoided.
Handling: Consult Material Safety Data Sheet (MSDS) for additional handling information on Isogran® IS 90-65.
