MEET OUR SUPPLIERS
ACCESS RUDOLF TECHNOLOGIES
Silicone emulsions, Silicone MQ resin technologies, specialty organofunctional Silanes, functionalized Silicone fluids, fluorine free stain repellant, Isocyanate, Block Copolymers and narrow molecular weight Polyethylene polymers.
BLACHFORD
Calcium Stearate and Zinc Stearate that act as process aids and anti-caking additive. These are suitable for 21CFR FDA indirect food contact and NSF applications.
BORICA
Tytan® Titanate coupling & dispersing agent that allows
higher filler loading without sacrificing mechanical strength.
BURGESS PIGMENT
Burgess Pigment is a manufacturer of hydrous and anhydrous kaolin for industry. Calcined kaolin options, as well as flash calcined kaolin grades are available. Kaolin products provide increased strength and endurance in
various polymers. Kaolin helps regulate curing rates, producing more consistency, increased strength, endurance in various polymers and increasing resistance to tears.
