Application
When precipitated silica is applied to shoemaking, rolls mixed time can be short with high DBP Absorption and good reinforcement.
its non-scuffing characteristics and to obtain compounds with light color or even transperant materials. Provides superior durability and resilience and improved modulus.
Acts as white reinforcer facilitating manufacturing of colored end
products.
We have recently introduced EVA grade for EVA footwear market. The
EVA grade can be incorporated as it imparts good abrasion and
modulus properties.
Because Precipitated Silica is white it allows the formulator to
produce either colored or translucent nonmarking soles.Precipitated
Silica provides superior durability and resilience while improving
compound stiffness for all types of rubber soled footwear.
