Hubersil 4155H, 1635 and 1745 are fine white, precipitated amorphous silicas in low-dusting granules.
They are highly reinforcing fillers for use in synthetic and natural rubber compounding.
The granulated form greatly reduces irritating dust for all applications where powdery material cannot by tolerated.
Precipitated amorphous silica increases hardness, tensile strength, abrasion and tear resistance.
For mechanical rubber goods, Hubersil can be used as the primary filler or in combination with carbon black.
White, colored and translucent articles are often based on Hubersil as the key reinforcing filler.
In tire applications, these silicas improve rolling resistance, flex fatigue and enhance traction.
In adhesives compounding, silica provides an additional method of promoting improved adhesion, as well as providing thixotrophy and reinforcement.
Hubersils are universally utilized to provide increased abrasion resistance, green strength and translucency in the formulating of shoe sole compounds.
Faster mix cycles can be an additional benefit of this physical form. |
