Purpose-engineered desiccant formulations that eliminate moisture defects in plastic manufacturing — at every production stage.
Our anti moisture powder actively scavenges and permanently locks moisture before it reaches the extruder, preventing silver streaks, bubbles, blistering, and surface voids.
Highly efficient formulation works at 1–3% loading rates, making it one of the most economical processing aids available for plastic manufacturers.
Unlike generic desiccants, our powder will not decompose or re-release moisture at processing temperatures exceeding 250°C — safe for all extrusion and molding operations.
Compatible with PP, HDPE, LDPE, LLDPE, PVC, and engineering polymers. Specially formulated variants available for recycled/reprocessed plastic feedstocks.
Every batch is quality tested for purity (99%), moisture absorption rate, and thermal stability before dispatch.
Supplied in sealed HDPE bags in 25–50 kg packs with 6–12 month shelf life. Custom packaging available for large-volume orders.
Specialized desiccant grades for every plastic processing application — from virgin resin to recycled granules.

About anti moisture powder for plastic manufacturing
Anti moisture powder is a desiccant additive used in plastic extrusion, injection molding, and blow moulding to eliminate moisture-related defects such as silver streaks, bubbles, blistering, and surface voids. It is especially important when processing recycled or reprocessed plastic granules, which tend to have higher moisture content.
Raviraj Minerals, based in Udaipur, Rajasthan, is one of India's leading anti moisture powder manufacturers. We supply ISO 9001:2015 certified desiccant powder to 5,000+ plastic processors across India and 25+ countries, with multiple grades for virgin, recycled, and specialty polymer applications.
Typical dosage rates range from 1% to 3% depending on the moisture content of the feedstock and the type of processing. Our Industrial Anti Moisture Powder is effective at 2–3% for recycled/reprocessed granules, while the Plastic Industry grade works at 1–2% for virgin polymer extrusion.
Our standard grades are white and colour-neutral for most applications. For transparent, translucent, or pure-white plastic products, we recommend our White Anti Moisture Powder, which is specifically formulated to have zero colour interference in the polymer matrix.
Yes, in many applications our Anti Moisture Powder For Plastic Industry can replace or supplement hopper drying, allowing continuous production without pre-drying downtime and reducing electrical energy costs significantly.
