Silane Coupling Agent TESPT
Introduction:
1. JERINA® TESPT is mixture of bis-(γ-triethoxysilylpropyl)-tetrasulfide (50%) and carbon black (50%).
2. JERINA® TESPT has the same function of Si69, and it’s solid form that more convenient for processing.
Technical Specification:

Sulfur content, % | 11.0-13.0 | Combustion method |
Heating Loss,% | ≤2.0 | Roasting method |
Insoluble in Butanone, % | 49.0-55.0 | Roasting method |
Ash content, % | 11.0-12.0 | Roasting method |
Performance:
1. JERINA® TESPT has been successfully used as the organic silane coupling agent with multi-functional groups in the rubber industry. It mainly used to enhance the elastic modulus and tensile strength of rubber, remarkably improving wear resistance and compressive performance, at the same time it can reduce the rubber viscosity, save working energy consumption. It is best suitable for polymers containing double bonds and rubbers with hydroxylic fillers in its formula. The suitable fillers include silica, silicate, chalk etc., and the suitable rubbers include NR, SBR, IR, BR, NBR, EPDM and so on.
2. JERINA® TESPT can provide more scorching safety because of its disulfur functional groups which have lower reactivity.
Application:
JERINA® TESPT is suitable for polymers like natural r ubber ( NR), isoprene r ubber (IR), s tyrene-e- butadiene rubber (SBR), butadiene rubber (BR), nitrile rubber (NBR), ethylene-propylene-diene rubber (EPDM), etc.
Packing and Storage:
1. It is packed in Kraft paper bags lined with plastic film, net weight is 25kg/bag.
2. It should be stored in a cool, dry warehouse.
3. The shelf life is 12 months.
