Product Overview
Desiccant Masterbatch is a concentrated additive containing active moisture-scavenging agents — primarily activated Calcium Oxide (CaO) and molecular sieve — uniformly dispersed in a polyolefin carrier resin (PP or HDPE). When added to your hopper during plastic processing, the active desiccant chemically reacts with and permanently binds any residual moisture present in the melt before it can vaporise and cause defects.
Moisture in plastic processing is a persistent and costly problem — especially in India's humid climate. It enters through hygroscopic resins, high-loading filler masterbatch, calcium carbonate powder additions, and — most significantly — through recycled plastic. When moisture reaches the processing temperature of 180–240°C, it vaporises instantly, creating the bubbles, voids, streaks, pinholes, and poor surface finish that cost processors in wasted material, downtime, and rejected product.
CHEMICALLANE's Desiccant Masterbatch eliminates this problem at the source — inside the melt — without requiring dryers, pre-drying cycles, or changes to your existing processing equipment. It is added directly to the hopper at 1–5% dosage alongside your base resin, scavenging moisture in real time during compounding or extrusion.
CaO chemically reacts with water permanently (no reversible adsorption). Molecular sieve adsorbs residual traces. Together they handle both high and low moisture levels in the melt.
Eliminate 2–6 hour drying cycles and dehumidifier capital cost. Add desiccant masterbatch directly to the hopper — no process changes, no downtime, no extra energy consumption.
Recycled PP, HDPE, and LLDPE carry significantly higher and more variable moisture levels than virgin resin. Desiccant masterbatch makes recycled plastic processable without expensive drying infrastructure.
CoA, MSDS, and TDS with every sealed batch. Critical for moisture-sensitive quality systems — your QC team needs proof of desiccant activity, not just pellet appearance.

Dual-action desiccant — CaO for chemical moisture binding, molecular sieve for trace moisture adsorption at the melt stage.
Minimum 20% moisture uptake by weight of masterbatch — verified on every batch via in-house activity test before dispatch.
Low addition rate — does not significantly affect melt flow, mechanical properties, or product colour at recommended levels.
Only in original heat-sealed inner foil bag. Once opened, the remaining masterbatch must be used in the same production shift.
The CaO desiccant in this masterbatch reacts with atmospheric moisture. Exposure to open air will deplete desiccant activity before the product reaches your melt. Always store sealed and use opened bags within the same shift. CHEMICALLANE's double-layer packaging (inner foil + outer PP bag) ensures full activity on delivery.

Request DocumentsProblems Solved
Moisture in the melt is responsible for more plastic processing defects than most operators realise. Here is what CHEMICALLANE's Desiccant Masterbatch fixes — permanently and without equipment changes.
Steam trapped in the melt creates visible bubbles and internal voids in film, pipe walls, and moulded parts — causing immediate rejection and wasted production runs.
Moisture vapour escaping along flow paths leaves silver streaks and flow marks on film and moulded surfaces — a sign of insufficient drying or wet filler masterbatch.
Micro-bubbles too small to see individually scatter light across blown film, reducing optical clarity and haze value — a critical defect for transparent packaging film.
Steam pockets at weld lines reduce bond strength in moulded parts. In film, micro-voids create pinholes that fail leak tests — costing packaging producers in customer returns.

Industrial Use Cases
Desiccant masterbatch solves moisture problems across every major plastic processing technology — but is especially critical wherever recycled material, high-loading filler masterbatch, or India's humid monsoon climate is a factor.
Eliminates bubbles and haze in HDPE and LLDPE blown film for packaging bags — especially critical when using recycled resin blends or high-loading CaCO₃ filler masterbatch.
Prevents tape breakage, surface defects, and uneven drawing caused by steam pockets in PP raffia extrusion — particularly when using high-loading filler or recycled PP.
The most critical application — recycled PP, HDPE, and LLDPE contain high and variable moisture that causes severe defects. Desiccant masterbatch makes recycled material processable without drying infrastructure.
Eliminates silver streaks, weld line weakness, and surface splay in moulded household goods, containers, and industrial components — common when using recycled or hygroscopic resin grades.
Prevents internal voids and wall irregularities in HDPE pipe extrusion — important where recycled HDPE is used in the compound or where CaCO₃-loaded grades are extruded.
Eliminates bubble inclusions, surface pits, and uneven thickness in PP and HDPE sheet extrusion — common defects when using calcium carbonate-loaded compounds in humid conditions.
Added during filler masterbatch compounding itself — scavenges moisture introduced by high-loading CaCO₃ (which is inherently hygroscopic) before it can cause die buildup or pellet defects.
India's June–September monsoon season dramatically increases ambient humidity and resin moisture content. Desiccant masterbatch provides year-round defect protection even when atmospheric moisture spikes.
Usage Guide
Unlike filler masterbatch where dosage is driven by cost savings, desiccant masterbatch dosage is driven by the actual moisture content of your raw materials. Higher moisture = higher desiccant dosage required.
The quickest way to determine the right dosage: start at 1% and increase in 0.5% steps until bubbles and surface defects disappear. Our technical team can also estimate the required dose if you share your raw material moisture content (ppm).
Get Custom Dosage AdviceManufacturing Process
Desiccant masterbatch is uniquely sensitive — the active CaO must remain unreacted throughout manufacturing, packaging, storage, and transit. Every stage of our process is designed around protecting desiccant activity until it reaches your melt.
High-reactivity CaO (≥ 92% purity) and pharmaceutical-grade molecular sieve sourced and activity-tested before being approved for production use.
Active desiccants and carrier resin blended under controlled low-humidity conditions — preventing premature CaO reaction before compounding.
Low-temperature twin-screw extrusion disperses desiccants uniformly in the carrier resin — temperature controlled to prevent premature activation during compounding.
Every batch is tested for moisture absorption capacity (≥ 20%) and MFI. Certificate of Analysis including activity test result issued before packaging approval.
Pellets immediately heat-sealed in inner aluminium foil / PE laminate bags under dry conditions — preserving 100% of desiccant activity until the bag is opened at your hopper.
Outer PP woven bag applied, CoA and MSDS attached. Dispatched with handling instructions clearly labelled — "Keep Sealed Until Use".

Client Testimonials
"We were getting severe bubbling on our blown film line every monsoon season for years. After using CHEMICALLANE's desiccant masterbatch at 2% dosage, the problem disappeared completely. Even in peak August humidity, our film quality is now consistent year-round."
"We shifted 40% of our blown film line to recycled HDPE to cut costs. The moisture issues were killing us — bubbles, streaks, and constant rejects. CHEMICALLANE's desiccant masterbatch at 3.5% sorted it completely. Their tech team helped us get the dosage right in two days."
"We use it in our filler masterbatch compounding line itself — at 1% alongside our CaCO₃. It's eliminated the die buildup and surface pitting we were getting from CaCO₃ surface moisture. The foil-sealed bag is a genuine quality differentiator versus other suppliers."
