Luna-sil SI69 is a silane coupling agent that is most commonly used in the rubber industry as a coupling agent. Use of Luna-sil SI69 will increase the modulus and tensile strength of the rubber, as well as reducing viscosity, which saves on energy consumption. Luna-sil SI69 can be used to incorporate fillers such as silicas, silicates and clays into polymers ranging from NR, EPDM, BSR and NBR.

CHEMIGUM® P7D is a specialized NBR powder designed for friction material modification, particularly in brake linings and clutch facings. It serves as a secondary binder, reducing noise and vibrations during use. With high gel strength in solvent-based processes, it ensures top performance and durability.

CHEMIGUM® P83 is a NBR powder grade used for PVC modification that requires chemical resistance while keeping good elongations. It is recommended for extrusion processed applications.
