Technology:
Pre dispersed Cao-80 is a kind of pre dispersed drier agent carried by EPDM/EVA mixed. Its combined elastomer contains thermoplasticity which not only melt with Polarity general plastic, but also melt with non polarity rubber.The combined elastomer and its surfactants & dispersants guarantee it can be absorbed quickly and perfect dispersed.Calcium oxide absorbs moisture to produce calcium hydroxide to makes rubber products avoid sponginess disfigurement because of the exists of steam when it is extruded and vulcanized under non pressure condition.Therefore, this kind of product could be applied to the constant vulcanizing extrusion processes that need hot air, Laboratory Fluid Bed Dryers ,salt bath.
Pre dispersed Cao-80 can also be used to foaming products, especially in micro hole sponge rubber products.
Advantage:
1.Easy operated
2.No blocking in normal storing
3.Good flowing and non dusty
4.Dispersed evenly
5.Suitable to some rubber products in different formula.
It is suggested feeding at the end of mixing because of the pre dispersed
Dosage:
General 2-10 phr, it depends on feeding volume,species,and moisture
Application:
Extrusion products (such as seal belt,rubber pipes) adhesive tape,conveyor belt,rubber covered roller,cable coat,rubber floor.
