Precipitated Silica(silicon doxide) Una.180
For sole making this type, can be packed in 20kg bag, wooden pallet.
Precipitated Silica ( Silicon Doxide ) Una.180 Una.180 is strongest rubber reinforcing agent, has many distinct excellence that improves tyre avulsion intersion resistance, boosts up tyre wall flection fatigue resistance, increases ankylosis capability without sulfurated glue,increases adhesion power which glue gives steel wire or shade fabric, reduces heat capacity of tyre face glueand enhances brake system. Packing: PP/woven bag, EVA/woven bag, kraft paper bag
