Reinforcing phenolic resins (RT 2***)
Reinforcing phenolic resins include straight phenolic resins and modified phenolic resins which show improved compatibility with rubber. The reinforcing resin can play the role of tackifying, plasticizing and softening of the rubber compounds before vulcanization to improve the processing performance. The performance of hardness, toughness, tear resistence, abrasion resistence will be improved.
This is achieved by the interpenetration of the three-dimensional mesh structure of hexamethylene tetramine and other methylene donors during their vulcanization with the three-dimensional mesh structure of the rubber.
RT60** is a kind of biomass modified reinforcing agent, which can be used to replace part of carbon black to improve the strength of tires and other rubber products. It can effectively reduce the heat built up and improve the thermal performance of the rubber material.
RT62** is a class of 100% bio-based reinforcing agent. It can partly replace the process oil during mixing to reduce the Mooney viscosity of the rubber material to reduce heat generation. Network interpenetration with rubber vulcanization network and reaction with the accelerator will occur to improve the modulus of the rubber materials during vulcanization.
Typical shelf life is 12 months.

Bonding resins (RT 31** Series)
The low content of free resorcinol in resorcinol formaldehyde resins can effectively solve the problems of high temperature sublimation of resorcinol in the mixing process. This affects the operating environment and the health of operators as well as the phenomenon of resorcinol on the surface of the compound, such as “spraying frost”. In combination with methylene donors bonding resins provide excellent adhesive properties leading to significantly improved bonding strength between rubber and fabrics made of various fibers and steel wire. Consequently the durability of the finished tire will be improved.
Typical shelf life is 12 months.
