Other Names

TESPT

Properties

CAS No.

40372-72-3

EINECS No.

254-896-5

Structure

40372-72-3 结构式

Appearance:

Yellowish clear liquid

Boiling Point (°C)

250

Flash Point (°C)

91

Applications:

Wide range of elastomers and applications such as cables, roller coverings, seals, conveyer/V-belts, shoe soles, hoses and tubes, molded articles.

Bis[3-(triethoxysilyl)propyl]tetrasulfide TESPT improves the tensile strength, modulus, compression set, and abrasion resistance for all commonly used elastomers. Best results are obtained at elevated mixing temperatures at about 120 – 140°C. Typical dosage is 10% of the silica-filler load. It is mainly recommended for sulfur crosslinked compounds. The EVA wax carrier protects the silane from
hydrolysis.

Packing:

Packed with 5L, 20L or 210L plastic/steel drum, 1000L IBC container, or according to customer’s requirement.
