Deolink TESPT-100

Technical Data Sheet Sample Request MSDS Request
Technical Data Sheet  Request a Sample Technical Data Sheet 

 Deolink TESPT-100 is an activator for filler.



BEHAVIOUR AND EFFECTS:
Due to its bifunctionality TESPT links through the tetrasulfane group to the rubber molecule and through the ethoxy group to the silanol groups of the filler. The chemical bond between polymer and filler improves the physical properties of the vulcanizate.
 



TYPICAL PROPERTIES:
Appearance                                                                       Dark yellow liquid
Active Substance                                                               bis(3-triethoxysilylpropyl)tetrasulfane TESPT    
Total sulphur (%) ASTM D 1552 (LECO)                           21 - 23
Density at 20°C (g/cm3) DIN ISO 787 part 10A                1.1
Dosage                                                                              1 - 8 %
                                                                                           in relation to silica-filler
 



APPLICATIONS:
Deolink TESPT-100 is used to improve tensile strength, modulus and abrasion of the vulcanizates in all commonly used elastomers. Deolink TESPT-100 should be dosed into the internal mixer together with the filler. Best results are obtained at elevated temperatures of about 120 - 140 °C. Mainly for compounds crosslinked through sulphur.
 



 STORAGE AND HANDLING:
 Store in originally sealed packaging in cool, dry places.
Shelf Life is min. one year  under the recommended storage conditions.
