Areas of expertise:
We have excellent distillation capabilities. We have particular strength in organosulfur
products (including thiophenols, isothiocyanates, sulfides, disulfides, sulfoxides,
sulfones and thiophenes) due to our ability to handle products with odors associated
with their production. Our Silar Laboratories division produces organosilanes,
such as triethylchlorosilane, triethylsilane, triisopropylchlorosilane and triisopropylsilane,
and custom silicones. Both bulk formaldehyde and hexamine are available
on site for use in making formaldehyde and hexamine derivatives.
Our plant is ISO 9001:2000 certified. Our Pharmaceutical Products Plant
operates under GMPs for excipients and food grade guidelines.
