Fire Retardant Resin — Halogenated & Halogen-Free
Fire retardancy in an unsaturated polyester comes from a deliberately added chemistry, not from the resin backbone. Two general routes exist: a halogenated backbone, where halogen species interfere with the combustion reaction in the flame itself, and mineral filling with aluminium trihydrate, which decomposes endothermically and releases water vapour that cools and dilutes the flammable gases. Samrat Poly Resins publishes one grade on each route.
Fire retardant is not the same as fireproof or non-combustible, and a resin does not carry a classification through into your part. Fire performance belongs to a finished system — resin, reinforcement, thickness, construction and the tested configuration together.

Choosing between them
Halogenated or halogen-free?
Halogenated route
Fire Retardant Resin
The separately published halogenated fire-retardant unsaturated polyester grade for industrial FRP work. Halogen chemistry acts in the gas phase, on the flame itself.
View Fire Retardant ResinHalogen-free, ATH-filled
ISO Fire Retardant Resin
An isophthalic-based, halogen-free grade filled with aluminium trihydrate. The halogen-free route matters where smoke toxicity and corrosive combustion products are a concern, such as tunnels, rail vehicles and enclosed public spaces. Here ISO means isophthalic chemistry, not certification.
View ISO Fire Retardant ResinHalogen-free, orthophthalic
Halogen-Free Fire-Retardant Resin
SPR 201 FR (HF): the halogen-free grade of the orthophthalic SPR 201 family, an opaque, higher-viscosity laminating resin for FRP laminates and marine components where the specification calls for halogen-free fire retardancy.
View Halogen-Free Fire-Retardant ResinNo grade here is stronger or safer than another in the abstract, and the isophthalic backbone on the ISO FR grade provides the corrosion and durability benefit rather than the fire behaviour. If your project names a class, a standard or a test method, send that wording exactly as written rather than summarised — it is what determines whether anything can be evidenced for your component.
