- Anti-block / Slip Masterbatch — Film Blocking Together or Feeding PoorlyFreshly 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 FilmWater 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 PartsPlastic 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 ResinRegrind 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 RatingA 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 PlasticA 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.
- Optical Brightener Masterbatch — Recycled or Off-White Plastic Looks Yellow or DullRecycled resin or off-spec white looks yellow or gray on the finished part, and the customer wants a cleaner, whiter appearance without going to full white pigmentation.
- UV Masterbatch — Plastic Fading, Chalking, or Cracking OutdoorsPlastic parts and films exposed to sunlight lose color, become chalky, or crack after months outdoors.
- Mineral Extenders for Paints, Coatings and Paper — Buying Function, Not BulkIn a coating or a paper furnish the mineral is not a diluent. It sets opacity efficiency, sheen, rheology, scrub resistance, printability and how much titanium dioxide you can remove without losing hiding power. Choose the extender by the property you are…
- Migratory vs Permanent Anti-Static — Which One Your Part Actually NeedsA migratory antistat works by blooming to the surface and attracting a thin water layer that conducts charge away. It is inexpensive, it works within hours to days, and it stops working when the humidity drops or when the surface is wiped, washed or…
- Internal vs External Lubricants in PVC: Balance, Fusion Time and Plate-OutNot every PVC processing problem is a lubrication problem. This article helps a production engineer decide when lubrication is the first place to investigate, and when it probably is not. Lubricants do not make PVC stronger. They help PVC process…
- Desiccant Masterbatch Explained: Moisture, Bubbles, Recycled PE, Dosage and StorageA Desiccant Masterbatch is a concentrated dispersion of Calcium Oxide in a polyolefin carrier, added to a base resin to consume residual water inside the melt. Once mixed into the melt at extrusion or injection temperature, the CaO reacts with residual…
- Desiccant Masterbatch Dosing — When It Fixes Bubbles and When It Hides a Drying ProblemA desiccant masterbatch converts trace moisture in the melt into calcium hydroxide so the water never becomes vapour in the die. It is a genuine fix for the residual moisture carried by recycled polyolefins and mineral fillers. It is not a substitute for…
- Which Masterbatch Solves the Problem I Actually Have? White vs Desiccant — The Diagnostic HubWhite Masterbatch and Desiccant Masterbatch sit next to each other in most masterbatch catalogs, but they solve fundamentally different engineering problems. White Masterbatch — a Titanium Dioxide-based system carried in a compatible polyolefin — addresses…
- Apparent Die Shear Rate & Melt-Fracture PredictorCalculate apparent wall shear rate for slit and circular dies and see when the line enters the sharkskin and melt-fracture window.
- Extrusion Troubleshooting & Process Diagnostics MatrixFind the root cause of gels, black specks, sharkskin, die build-up, thickness variation and other extrusion defects, with the checks and remedies for each.
