Deolink TESPT
Chemical Name:Bis(3-triethoxisilylpropyl)tetrasulfide = TESPT
Supplier:DOG Chemie
SILANES
Auf die Merkliste
CAS number:40372-72-3
Coupling agent
50% in EVA wax mixture offers excellent protection against moisture and other environmental influences
Bifunctionality: connects the tetrasulfane group with the rubber and the ethoxy group with the silanol groups of the filler
Chemical bonding between the polymer and filler improves physical and mechanical properties (tear strength, modulus, abrasion)
Addition of filler and higher mixing temperatures (120-140 °C) recommended
Mainly sulfur cross-linking compounds
Sulfur content: 10-13%
Drop point: 67-77 °C
Deolink TESPT can be dosed between 2 and 16 phr (depending on filler)
Sold as: Yellow pastilles
