YH-75(Si75) its application can perfect the physical and mechanical performance of rubber. Improve the tensile strength,tear resistance strength, wear-resisting performance etc. All can be enhanced obviously, permanent deformation reduced, at the same time can also reduce the viscosity of rubber, improve the processing performance. Especially suitable for vulcanized rubber system taking white carbon or silicate as reinforcing agent and because of this products has low activity of disulfide functional groups, therefore can provide reliable sorch safety.
YH-75(Si75) is especially suitable to improve the reinforcing properties of fillers that contain hydroxyl groups in all unsaturated polymers having double bonds or theirblends. Silica, talc powder, mica powder and clay can be used in combination with HR-75(Si75) in polymers such as NR, IR, SBR, BR, NBR and EPDM.
