AL2CHEM SPECIALTIES AL PS-40 Silica

AL PS-40, a precipitated, non-crystalline, amorphous silica, is an excellent silica for improving mechanical properties of rubber and elastomers. Due to its high level of absorption, it can be used as a carrier for liquid additives in applications such as animal feed. It is also an excellent thickener in liquid systems.
