Flame Retardant Masterbatch
Makes plastic resist burning, for cables, housings and electrical parts.
Flame Retardant Masterbatch (FR) makes plastic resist catching fire and stop burning once the flame is removed. It comes in halogen-free and halogenated grades to meet UL 94 V-0, V-1 and V-2 fire ratings on PE, PP and EVA. Used in cable jackets, electrical housings and building parts.
The range covers halogen-free and halogenated grades on an LDPE or PP carrier. The standard grade is halogen-free and works by forming a protective layer that swells and shields the plastic when it heats up. Mineral-based grades are available for cable compounds, and a halogenated grade is supplied where thin, light-weight parts need it. Made for cable, electrical, construction and electronics work that has to meet UL 94 V-0 and the relevant cable fire standards.

Key benefits
Self-extinguishing performance
Stops flame propagation on ignition and meets stringent fire-safety standards for cables, electronics and construction parts.
UL 94 V-0 / V-1 / V-2 ratings achievable
Formulated grades hit industry-standard flammability ratings across PE, PP and EVA at recommended loading levels.
Low smoke emission options
LSZH grades minimise smoke density and toxic fume release in case of fire, critical for tunnel and transit cable installations.
Halogen-free variants available
Halogen-free grades give effective fire protection with a cleaner environmental profile.

Frequently asked questions
What is FR Masterbatch used for?
It makes plastic parts more resistant to catching fire and slows the spread of flame. Typical uses include electrical parts, building products, cable and appliance housings.
Which polymers does it work with?
Standard grades are compatible with polyethylene and polypropylene. We match the carrier resin to your base resin so the masterbatch melts and disperses cleanly during processing.
Can I get a trial sample?
Yes. Share your base resin, end application and the flame performance you need to meet, and we will ship a matched grade for line evaluation along with a Certificate of Analysis.
What flame performance can it reach?
Performance is matched to your application and the standard you are working to. Share the target at the enquiry stage and we will recommend a suitable grade.
What is the typical lead time?
Standard grades ship in 7 to 14 working days from order confirmation. Custom formulations matched to a specific application take 3 to 4 weeks. We confirm an exact timeline at the quote stage.
