Pre-dispersed desiccant CaO-80

The pre-dispersed desiccant CaO-80 is a pre-dispersed granular desiccant combined with EPDM/EVA blending carrier. Its combined elastomer has processing thermoplasticity, which is compatible with general rubber and rubber. The combined elastomer and its surface active dispersing additive ensure that the product can be rapidly absorbed and dispersed in rubber. Calcium oxide absorbs water vapor to generate calcium hydroxide, which enables the product to be continuously extruded and vulcanized under pressureless conditions, to avoid spongy defects due to the presence of water vapor, the product is particularly suitable for extrusion compounds that need to be continuously vulcanized in hot air, vulcanizing bed, salt bath or microwave equipment; because the cell structure can be more uniform, The pre-dispersed desiccant CaO-80 can also be used for foamed products, especially microporous sponge rubber products.

MB-80 of pre-dispersed antioxidant

Pre-dispersed antioxidant MB-80 is mainly used as a synergistic agent of other antioxidants, and the combined effect of other antioxidants is usually better than the sum of their effects when used alone; it is a medium-strength non-polluting antioxidant, especially suitable for compounds containing overspeed accelerators and heat-resistant compounds containing no sulfur but containing thiuram TMTD-80; when MB-80 with sulfenamide CBS -80 or thiazole MBT-80 or thiuram and dithiocarbamate accelerators, the pre-dispersed antioxidant acts as an anti-scorching agent to improve the processing safety and storage stability of the rubber compound. However, the pre-dispersed antioxidant MB-80 slightly reduce the modulus of NR and synthetic rubber products. If the dosage is recommend, no blooming will occur.

Pre-dispersed vulcanizing agent DTDM-80

DTDM-80 pre-dispersed vulcanizing agent can release free sulfur under normal vulcanization conditions. Different from ordinary sulfur, it mainly forms mono-sulfur bond and di-sulfur bond, and vulcanizate has excellent heat aging resistance. As a crosslinking agent, this product will not appear similar to the blooming phenomenon when using thiuram dithio; The acidic component in the formula will cause the pre-dispersed vulcanizing agent DTDM-80 to decompose prematurely and reduce the scorch safety; usually this product is used for low compression deformation and heat aging properties of high rubber.

Pre-dispersed accelerator ETU(NA-22)-80

Pre-dispersed accelerator ETU(NA-22)-80 makes chloroprene rubber vulcanized quickly and scorch safely. For low-sulfur or sulfur-free vulcanization of other diene rubber, it can be used as activator and auxiliary accelerator. Pre-dispersed accelerator ETU(NA-22)-80 can improve the heat aging resistance and physical and mechanical properties of vulcanized rubber, and generally does not spray frost.
