Flame Retardant Masterbatch Manufacturer — Compounded and Pelletized In-House
Rectivas Materials compounds and pelletizes flame retardant masterbatch at our own facility in Shijiazhuang, Hebei — carrier resin matched to your process, dispersion checked before we ship a sample. This page covers how we build a masterbatch grade and what to send us to get one started.

01 / 06Who Makes It
Compounded on our own line, not sourced and repackaged.
Masterbatch pellets are made the same way our powder additives are — formulated, compounded on our SHJ-75 twin-screw extruder, pelletized, then burn-verified before a sample goes out.
Compound & Pelletize
Twin-screw compounding followed by pelletizing on-site — the same equipment behind every carrier grade we quote.
Dispersion & Burn Verification
Let-down trials and UL94 burn testing done in-house before a masterbatch grade is recommended.
02 / 06What We Make
Carrier and system coverage.
| Carrier | System | Typical Use |
|---|---|---|
| PP carrier | Halogen-free / brominated | Injection molding, extrusion let-down into PP |
| PE carrier | Mineral / halogen-free | Film, pipe, cable, molding into PE/HDPE/LDPE |
| PVC carrier | Antimony / zinc borate systems | Cable, profile, sheet PVC compounds |
| EVA / custom carrier | Project-dependent | Cable jacket and specialty let-down applications |

06 / 06FAQ
Questions buyers ask before sourcing masterbatch.
Is Rectivas a flame retardant masterbatch manufacturer or a reseller?
Rectivas compounds and pelletizes masterbatch in-house on our own twin-screw line in Shijiazhuang, Hebei — we are not reselling a third party’s pellets under our own label.
Can Rectivas match my specific carrier resin for masterbatch?
Yes — carrier resin is matched to your process (PP, PE, EVA, PA or a project-specific carrier) so the masterbatch disperses cleanly at your let-down ratio.
What is the minimum order quantity for flame retardant masterbatch?
Order volumes are confirmed per project rather than fixed to one number — tell us your trial or repeat-order target and we will confirm what is workable for your carrier and system.
Can I get a sample of flame retardant masterbatch before a bulk order?
Yes — send your carrier resin, target let-down ratio and flame rating, and we will propose a masterbatch grade and arrange a sample for your own dosing trial.
Does Rectivas supply flame retardant masterbatch wholesale for distributors?
Yes — repeat-order volumes for resale are supported, with the same batch-to-batch consistency and document set as a direct end-user order.
