Borregaard is a leading supplier of sustainable biopolymers to the gypsum board industry. We strive to improve our customers’ production performance and support their strategies to contribute to a safer and more sustainable environment.
Gypsum Board Additives
We offer a standard range (BorreGYP, Borresperse®) and a superior range (Ultrazine®) of lignosulfonates for this application. Our products can be used as high-performance water reducers/fluidisers to produce formaldehyde-free plasterboards with both natural and synthetic gypsum. Additionally, they are preferred additives for ball mill accelerators (BMA) and heat-resistant accelerators (HRA) and help enhance production efficiency.
Our biopolymers are based on lignin, the natural binding agent in trees. They represent an excellent sustainable alternative to synthetic polymers.
