NP

General Product Data

NP is our most technically advanced additive, a fully formulated one-shot intumescent flame retardant. Set apart by its high thermal stability, NP is the flame-retardant additive of choice for PP, PE, HDPE, EVA, EBA, EEA, etc., whilst also very effective in paints, mastics, coatings, sealants and adhesives. We are working towards achieving REACH registration for NP in 2018.

Typical Applications

NP is the ideal halogen-free flame retardant for olefinic polymers such as PP, LDPE, HDPE and their various co- and terpolymers. It is also very effective in paints, mastics, coatings, sealants and adhesives employed in the building and construction industries.
