Desiccant Masterbatch
Eliminates moisture defects for superior processing performance.
Desiccant Masterbatch is a calcium oxide moisture absorber in pellet form. It locks up the water in your resin before it turns to steam, so pinholes, bubbles and streaks stay out of the finished part.
Plastic, fillers and recycled material all carry moisture into the line. Because the absorber sits inside a polyethylene pellet, it feeds straight from the hopper with your resin, with no dust or special dosing equipment, and it melts along with the resin as it processes. On polyolefin lines it often removes the need for a separate pre-drying step.
3 grades
Three grades, tuned to absorption capacity and end-use.
All three grades share the same calcium oxide chemistry on a polyethylene carrier. They differ in moisture absorption capacity and the applications they are best suited for. Tell us the host resin and line, and we will recommend the right grade.
-
Dry-Addi
Desiccant masterbatch with highly reactive absorbers and controlled dispersion, capturing moisture at lower dosages without clogging screens, filters or dies. Suited to high-clarity films, lamination and multilayer structures, and recycled blends. The particle morphology is chosen to limit screw and barrel abrasion.

Sanjivini
High-performance desiccant masterbatch for effective moisture control in polymer and recycled plastic processing. Absorbs residual moisture during processing, reducing defects such as bubbles, voids, fish-eyes and silver streaks, and in many applications can reduce or eliminate the need for pre-drying. Balanced combination of performance and cost-efficiency.

Shine-Addi
Cost-effective, moisture-absorbing masterbatch for general-purpose polymer processing. Reduces moisture-related defects in reprocessed and moderately moist raw materials, so processing stays stable and the finished product holds its quality. Suited to routine production where performance needs are standard and cost matters most.

Key benefits
Rapid moisture absorption
The calcium oxide absorber captures moisture during processing, often cutting drying time and energy use.
Reduces moisture defects
Helps remove bubbles, pinholes, voids, haze and moisture streaks from the finished part.
Excellent dispersion
Disperses cleanly with minimal specks and streaking, supporting stable melt pressure and consistent output.
Works across resin streams
Consistent performance in virgin, reprocessed and mixed resins on standard equipment, no special screw design or modifications needed.
Applications
HDPE Pipes & Fittings
Blown Film
Tarpaulins

Plastic Automotive Moulded Parts
Frequently asked questions
What is Desiccant Masterbatch used for?
It absorbs moisture that gets into recycled or filled plastic, preventing bubbles, voids and surface defects during processing. Typical uses include recycled film, blown film and moulded parts.
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 the resin and moisture problem you are seeing, and we will ship a matched grade for line evaluation along with a Certificate of Analysis.
How much is added?
The right loading is matched to how much moisture your material carries. We advise a suitable level at the enquiry stage.
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.
