Modifier Polybooster W
Helps woven sack and FIBC compounds carry more filler without losing strength.
Modifier Polybooster W is a modifier for heavily filled PE and PP compounds. It makes them easier to process, lets them stretch further, lifts gloss and surface finish, helps the filler bond and seal better, and lets you add more filler (and use less white masterbatch) without losing strength.
The result is a tougher, more even compound that stretches consistently and runs more smoothly on the line, with less powder and build-up. It is most often used in woven sacks, jumbo bags (FIBC), blown film and tarpaulin compounds with moderate to high filler levels, where it helps processors push filler loading higher while keeping the strength and finish the product needs. It is supplied as ready-to-use pellets that run on your existing line with no equipment change.

Key benefits
Add more filler, cut cost
Lets you raise mineral-filler loading and reduce white masterbatch use without losing strength.
More stretch, same strength
It lets the compound stretch further without losing strength, even when heavily filled.
Better gloss, bonding & sealing
Improves surface gloss and helps the filler bond better, with stronger sealing.
Cleaner, higher-output line
Steadier flow with less dust, build-up and waste on the line.
Applications
Frequently asked questions
What is Modifier Polybooster W used for?
It is a modifier for filled polyethylene and polypropylene that improves processing, strength and finish, so you can add more filler to cut cost. Typical uses include woven sacks, FIBC bags and film.
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 your compound and filler level, and we will ship a matched grade for line evaluation along with a Certificate of Analysis.
What does it improve?
It improves processability, stretch and surface finish, and helps the filler bond better, so you can load more filler without losing strength.
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.
