Pre-dispersed rubber masterbatch series

Pre-dispersed accelerator MBTS(DM)-75

Pre-dispersed accelerator MBTS(DM)-75 is a general-purpose quasi-speed accelerator with good processing safety, which can be used alone or in combination with other accelerators. In combination with activated dithiocarbamate accelerators, scorching can be prevented. Thuram, dithiocarbamate and aldehyde amine accelerators have activation effects on MBTS(DM)-75; it has a delaying effect in the processing and vulcanization of CR compound. When combined with overspeed accelerator, MBTS(DM)-75 can improve the processing safety.

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.

Pre-Dispersed Brightener TiO2-80

Pre-dispersed whitening agent is TiO2-80 suitable for printing plates, printing rollers, copier tapes and other light-colored rubber products with strict surface requirements and no defects. At the same time, it also has the function of protecting the surface of white or light-colored rubber products from sunlight and ultraviolet light.

Pre-dispersed crosslinker TCY-70

Under normal circumstances, the pre-dispersed crosslinking agent TCY-70 can be used as an effective vulcanizing agent for halogen-containing rubber, such as CO, ECO, CIIR and BIIR, as well as a vulcanizing agent for ACM rubber and a co-vulcanizing agent for NBR/PVC blended elastomer. Mixing compound containing TCY-70 is easy to scorch, so the mixing temperature should not be too high or the mixing time should be as short as possible, and the mixing time should not be too long, the compound is stored at a lower temperature; however, in order to improve the storage stability of the compound containing TCY-70, a pre-dispersed scorch retarder CTP-80 can be added to the formulation; in addition, TCY-70 has a tendency to increase the bond strength of rubber to metal.

Pre-dispersed foaming agent OBSH-75

The pre-dispersion of organic foaming agent for rubber can start foaming OBSH-75 at 150 ℃ and release N2. Adding appropriate foaming active agent can further reduce the initial foaming temperature, and reasonable design and reasonable matching of foaming speed and vulcanization speed can improve the foaming quality. Thermoplastic EPDM/EVA as an effective pre-dispersion carrier can promote OBSH rapid mixing and uniform dispersion.

Details

Pre-dispersed accelerator DOTG-70

The DOTG-70 of the pre-dispersed accelerator will lead to a very slow vulcanization start and a relatively slow vulcanization rate; the use of the pre-dispersed accelerator alone will DOTG-70 cause serious reversion, so it is necessary to use an effective antioxidant; when the pre-dispersed accelerator DOTG-70 is used in combination with thiols, sulfenamides, thiurams and dithiocarbamates, synergistic effect and secondary promotion effect can be obtained, and the crosslinking density and vulcanization rate are improved, the mechanical properties and anti-aging properties of the vulcanizate are good; the pre-dispersed accelerator DOTG-70 has no blooming phenomenon in the vulcanizate.

Pre-dispersed accelerator ZMBT(MZ)-80

The pre-dispersed accelerator ZMBT(MZ)-80 is a quasi-overspeed and multifunctional accelerator for natural rubber and synthetic rubber, which endows vulcanized rubber with good physical and mechanical properties. Its vulcanization behavior is the same as that of the pre-dispersed accelerator MBT(M-80), the critical vulcanization temperature is 138 ℃, the vulcanized rubber has good aging resistance, it will neither change color nor pollute color, and can be used in light-colored rubber products.

Details

Pre-dispersed accelerator MBT(M)-80

Pre-dispersed accelerator MBT(M)-80 is a kind of quasi-speed and multi-functional accelerator with long vulcanization flat period, which endows vulcanizates with good physical and mechanical properties. In sulfur-free vulcanization compound, pre-dispersed accelerator MBT(M)-80 is used as anti-scorching agent; In CR compound, it is used as vulcanization retarder; alkaline accelerators such as aldehyde amines, guanidines, etc., as well as thiuram and dithiocarbamate accelerators are used to activate MBT(M)-80.
