| HUBERSIL 1613 |
 |
| Amorphous silica, precipitated |
 |
Hubersil 4151H, 162, 1613 and 1714 are fine white, spray-dried, precipitated amorphous silicas.
They are highly reinforcing fillers for use in synthetic and natural rubber compounding.
These spray-dried silicas have a larger particle size than the milled Hubersils.
Advantages are faster incorporation time and less viscosity buildup while maintaining excellent dispersion.
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 applied to provide increased abrasion resistance, green strength and translucence in the formulating of shoe sole compounds. |
