SI69-50

Description

This Rubber Coupling Agent SI69-50 has the role of activator, coupling agent, softener , reinforcing agent and vulcanizing agent in rubber industry. It can reduce the Mooney viscosity of the rubber compound and improve the extrusion and rolling properties, and increase the tensile strength, dynamic properties , tear strength and wear resistance of vulcanizates.

Function

The silane coupling agent JXBHgran SI69-50 not only has the function of an activator and a coupling agent, but also has the function of cross-linking reinforcing serving as a reinforcing agent and a vulcanizing agent in the rubber industry. It can be used in natural rubber, isoprene rubber, styrene butadiene rubber, butadiene rubber, neoprene rubber and other synthetic rubber. It can increase the tensile strength, tear strength and wear resistance of vulcanizates, and at the same time improve the dynamic properties of vulcanizates.

Dosage

In accordance with the formula used twice the amount of silane coupling agent Si-69.

Application

It can be used for tires, hoses, conveyor belts, rubber shoes and so on. It is widely used in the production of radial tires.
