Desiccant Masterbatch
Absorbs moisture inside the melt for smooth, bubble-free output.
Desiccant Masterbatch is a moisture absorber in pellet form. Plastic, fillers and recycled material carry moisture into the line, and when that moisture turns to steam during processing it leaves pinholes, bubbles and streaks in the finished part. Desiccant Masterbatch puts a calcium oxide based absorber inside a polyethylene pellet, so it can be added at the hopper along with your resin.
Because the absorber sits inside an off-white pellet, it runs through normal feeders with no dust or special dosing equipment. The pellet melts along with your resin, and the calcium oxide locks up moisture as it processes, often removing the need for a separate pre-drying step on polyolefin lines.
Three grades cover the performance range. Dry-Addi is the advanced grade for high-clarity, thin-gauge, lamination and multilayer films and premium recycled blends. Sanjivini delivers high absorption for general processing and recycled blends. Shine-Addi is the cost-optimised grade for routine production where standard moisture control is sufficient.
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
Advanced, next-generation desiccant masterbatch with highly reactive absorbers and controlled dispersion, capturing moisture faster at lower dosages without clogging screens, filters or dies. Engineered for the work conventional desiccants struggle with: high-clarity and thin-gauge films, lamination and multilayer structures, and premium recycled blends. Cleaner dispersion and lower screw and barrel abrasion mean a better surface finish and longer equipment life.

Sanjivini
High-performance desiccant masterbatch with high moisture absorption for polymer and recycled plastic processing. Reduces moisture-related 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.
Request a sampleShine-Addi
Cost-effective, moisture-absorbing masterbatch with moderate absorption capacity, designed for general-purpose polymer processing. Reduces moisture-related defects in reprocessed and moderately moist raw materials, suited to routine production where standard performance and cost optimisation are critical. Not recommended for high-clarity, thin-gauge or lamination films.

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
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.
