Pre-dispersed halogen-free flame retardant masterbatch for PP, PE, EVA, POE, TPE, LSZH cable compounds and selected plastics. Carrier resin, active loading, let-down ratio, UL94 or LOI target, low-smoke requirement and processing window can be adjusted by project.

Halogen-free flame retardant masterbatch is a pellet concentrate made by dispersing non-halogenated flame retardant additives into a compatible carrier resin. It helps compounders, extruders and molders reduce dust, simplify dosing and improve dispersion compared with direct powder handling.
Non-halogenated flame retardant ingredients are compounded into PP, PE, EVA, POE or custom carrier resin to improve feeding, dispersion and repeatability on plastic processing lines.
Carrier direction is selected to match PP, PE, EVA, POE, TPE or cable compounds, with processing temperature, melt flow, color and final mechanical performance considered together.
Halogen-free masterbatch can be dosed at the hopper by gravimetric or volumetric feeding, making it practical for extrusion, injection molding, sheet, profile and cable compound trials.

The right direction depends on base polymer, processing temperature, target rating, smoke requirement, loading, color and mechanical property retention.
For PP, polyolefin and selected plastic applications where halogen-free chemistry, char formation and balanced mechanical properties are required.
For PP and polyolefin projects where expansion, char formation, drip behavior and UL94 target need to be managed together.
For LSZH, EVA, PE or cable-related compounds where low smoke, filler loading, flexibility and process stability need to be balanced.
For applications where PP, PE, EVA, POE or other carrier resin must be matched to the buyer's base polymer, processing line and let-down ratio.
Use this table as a first filter before sample testing. Halogen-free flame retardant masterbatch should be matched by polymer, carrier resin, process, loading, target flame or smoke standard and end-use requirements.

Halogen-free flame retardant masterbatch is usually selected when buyers want cleaner dosing, lower dust, easier feeding and more consistent dispersion on extrusion, injection molding or cable compound lines.
You need maximum formulation control, direct compounding, active ingredient adjustment or integration with an existing compound recipe.
You need cleaner dosing, easier handling, better pre-dispersion and direct let-down on plastics, polyolefin or cable compound production lines.
A useful halogen-free masterbatch recommendation requires more than the phrase non-halogenated. Base polymer, carrier resin, loading, let-down ratio, UL94 thickness, smoke target and processing conditions all affect final performance.
As a halogen-free flame retardant masterbatch manufacturer, we support carrier selection, compounding, pelletizing, sample trials, batch production, quality control and export packaging — with carrier compatibility and dispersion control confirmed before scale-up.

Halogen-free flame retardant masterbatch is a pre-dispersed pellet concentrate containing non-halogenated flame retardant additives in a compatible carrier resin. It is designed for easier dosing, cleaner handling and more consistent processing in plastics and cable compounds.
It is used in PP, PE, EVA, POE, LSZH cable compounds, TPE, sheet, profile, extrusion and injection molding applications where non-halogenated chemistry, cleaner handling and pre-dispersion are needed.
Carrier resin is selected by the target polymer and process. Common directions include PP carrier for polypropylene, PE carrier for polyethylene, EVA or POE carrier for cable compounds, and custom carriers for special applications.
