HaflonTM Halogen-free flame retardants

NP1020

Halogen-free flame retardants used in PBT

Product Features

NP1020 is a halogen-free flame retardant based on organic phosphinates. The polymer with NP1020 will expand and crosslink when burning and form a stable carbon layer at the surface. The protective layer provides a heat insulation effect, reduces oxygen access and prevents the further spread of flame, plays a role in fire retardant. The flame retardant is not hydrolyzed, not precipitated, has good self-extinguishing properties into carbon

Specification and Technical Data

Applications

NP1020 is white particles, developed especially for PBT. It is suitable for both glass fiber reinforced PBT and non-reinforced PBT. The flame retardant PBT exhibits excellent physical and electrical properties.

Formulation

In glass fiber reinforced PBT, recommended to add 13 to 16% (by weight). NP1020 is usually sufficient to achieve the UL94 V-0 flame retardant requirements (at 1.6 mm thickness).Due to different formulations and processing conditions, the dosage of flame retardant may be different

Package:

25 kg /bag, using paper bags with PE inner.
