Molecular Formula:C18H42O6S4Si2
CAS NO.:40372-72-3
EINECS No.:254-896-5
Main application:Rubber,Spinning,Coating,Tyre
Application:Si-69 is a kind of silane coupling agent with multiple functional groups successfully used in rubber industry to improve modulus and tensile strength of rubber, to reduce the compound viscosity and save process energy consumption. It is especially applicable for polymers with double bond or rubber formulation with hydroxyl fillers. The suitable fillers include silica, silicate, clay, etc. The suitable rubber include natural rubber (NR), Butadiene styrene rubber (SBR), Isoprene rubber (IR), Butadiene rubber (BR), Acrylonitrile butadiene rubber (NBR), Ethylene propylene diene rubber (EPDM), etc.
Used as rubber’s annexing agent;additive of Rubber,Vulcanizer,Active Agent;used to produce Tyre,Rubber Hose,Cable Insulation and so on.
Package:25Kg,200kg,100kg per plastic drums or according to the customers’ requirement.
Storage:Stored in protected against light, moisture,water & heat.
Safety Protection:Using the organic aerosol type of respiratory protection equipment,safety glasses and chemical gloves.Should do some properly cleaning after operating.
