Pre-dispersed active agent ZnO-80

Pre-dispersed active agent ZnO-80 is a kind of pre-dispersed special zinc oxide suitable for rubber industry. Combined with elastomer, it can prevent moisture absorption in air during storage. Due to more uniform dispersion, compared with powdered zinc oxide extrusion compound, the surface of extrusion profile of rubber compound containing pre-dispersed active agent ZnO-80 is smoother. Generally, the definite elongation and tensile strength of vulcanized rubber containing this product are improved, and the elongation at break is also improved.

Pre-dispersed accelerator DPG-80

The scorch time of the pre-dispersed accelerator DPG-80 is long and the vulcanization speed is slow, which will cause slight discoloration and cannot be used in light-colored products unless used as an active agent. When the pre-dispersed accelerator DPG-80 is used alone, the vulcanizate has poor thermal oxidative aging resistance (effective antioxidant is required); The pre-dispersed accelerator DPG-80 can effectively activate thiol accelerator. The pre-dispersed accelerator DPG-80 has no vulcanization promotion effect on butyl rubber IPDM and ethylene propylene rubber EPDM.

Pre-dispersed accelerator NOBS(MBS)-80

The pre-dispersed accelerator NOBS(MBS)-80 makes the scorch time of the compound quite long, the processing safety is very high and the vulcanization is very complete. It can be used alone as the main accelerator in low-sulfur vulcanization, or it can be used in combination with dithiocarbamate or thiuram accelerator, and the resulting vulcanizate has good heat aging resistance and good compression deformation; pre-dispersed accelerator NOBS(MBS)-80 and dithiocarbamate accelerator and thiuram accelerator will significantly reduce the scorch time of the compound. The combination of thiuram TMTM-80 accelerator and pre-dispersed accelerator NOBS(MBS)-80 has a particularly obvious promotion effect of shortening vulcanization time, and has good anti-scorch effect and high crosslinking degree. In low sulfur compound, in the compound containing sulfur alcohol accelerator and thiuram accelerator, the pre-dispersed accelerator NOBS(MBS)-80 can delay scorch.

Pre-Dispersed Adhesive R-80

R-80 is one of the components of resorcinol/formaldehyde/silica adhesive system. The resorcinol-formaldehyde-resin system can be used during processing with a formaldehyde donor such as HEXA-80 or RA-65 to form a rubber-to-fabric or steel cord bond; this system is suitable for bonding various rubbers to reinforcing materials, for example, fibers, glass fibers and metals such as steel cords.
