Wallace FR specialises in Zinc Borate.
Zinc Borate is an inorganic compound used as a flame retardant and a smoke suppressant.
Applications
Zinc Borate is used as a flame retardant and a smoke suppressant for wide range of plastics, rubbers, paper and textiles, it can also be used in paints, adhesives, pigments and ceramic industrial applications.
Zinc Borate meets the stringent fire legislation in terms of flame, smoke and processing. A non-toxic, low-water-soluble and has a high heat stability. Reduces smoke emissions depending on the formulation and promotes charring which can lead to lower overall filler loadings.
Zinc Borate is also known as ZB2335
