Halogen-Free vs Halogenated Flame Retardants — Choosing on Evidence
Halogenated systems interrupt combustion chemically in the gas phase, which makes them extremely efficient: a brominated package with an antimony trioxide synergist reaches a UL 94 V-0 rating at loadings low enough to leave mechanical properties largely…
Impact Modifiers — Selection by Polymer
An impact modifier is a rubbery phase dispersed in a rigid polymer to stop brittle failure. There is no universal grade: polyolefins take POE or EPDM, rigid PVC takes acrylic core-shell, MBS or CPE, and PET takes polyester-specific systems.
UV Stabilizer Selection — HALS, Absorbers and the Difference That Matters
A UV absorber and a hindered amine light stabilizer do different jobs. The absorber intercepts UV photons before they reach the polymer backbone and works best in thicker sections where there is enough path length to absorb in. HALS does not absorb UV at…

Anti-block / Slip Masterbatch — Film Blocking Together or Feeding Poorly
Freshly wound film sticks to itself, or converted bags do not open or feed through packaging machines.
Anti-fog Masterbatch — Fog or Water Droplets Inside Greenhouse or Food Packaging Film
Water condenses as droplets inside greenhouse film (blocking light) or food packaging film (blurring product view and dripping onto food).
Anti-static Masterbatch — Static Electricity on Plastic Film or Parts
Plastic parts or film hold a static charge — attracting dust, sticking, or creating ESD risk in electronics packaging.
Desiccant Masterbatch — Bubbles, Streaks, or Splay When Processing Regrind or Wet Resin
Regrind or hygroscopic-contaminated resin produces bubbles, silver streaks, or splay marks in the finished part, and drying is not practical or sufficient.
Flame Retardant Masterbatch — Plastic Burns or Fails a Flame Rating
A plastic part must pass a flame-rating standard (e.g., UL 94 V-0, glow-wire, FMVSS 302) and the base resin fails.
Laser-Marking Masterbatch — Cannot Laser-Mark on Dark or Colored Plastic
A part needs a permanent, high-contrast laser mark (barcode, batch code, logo) and the base resin does not respond — the mark is faint, blurred, or invisible.
