Product Description CaO can absorb moisture to form calcium hydroxide that avoids sponge defect caused by vapour in continuous extruded vulcanization without pressure. CaO-80 is especially used for rubber compounds vulcanized by hot air, fluidized bed, salt bath or microwave devices. CaO-80 is also used for foaming products, especially porous sponge products, because it makes foam structure homogeneous.

 

Processing Characteristics CaO-80 has good dosing and mixing property, and won’t cake at ordinary temperature and humidity. It has good fluidity, no irritating dust and no material loss. It keeps optimal activity of CaOand easily disperses in kinds of rubber compounds. Recommend that CaO-80 is added at last stage of mixing.

 

Dosage 2.0~10.0 phr.

 

Applications CaO-80 is used in extruded products, rubber belts, conveyer belts, rubber rolls cable sheath and rubber floors, etc..

 

Packaging Coextruded paper bags lined with plastic film, net weight 25Kg/bag.

 

Storage Store in a cool, dry, well-ventilated area away from sunlightfor up to 1 year.
