CaO-Based Desiccant Masterbatch

Overview

Many plastic manufacturers especially those using recycled resins often struggle with moisture issues during processing.      Whether it's unwanted bubbles in film or streaks on injection parts, excess water can disrupt production and hurt product quality.

Our calcium oxide-based desiccant masterbatch tackles this problem at its root. Instead of relying on costly drying systems,      processors can simply blend this additive directly into the resin mix, letting the CaO component absorb moisture during melt processing.

Why Use It

• Permanently removes moisture through chemical reaction (CaO + H₂O → Ca(OH)₂)

• No drying equipment required, simplifying production

• Both recycled and virgin plastics can be used

• Processing issues such as bubbles, streaks, and warping are significantly reduced

• Reduces costs by reducing scrap

Processing Applications

• Injection Molding: Use in PA, ABS, or recycled PP to prevent streaks, poor flow, or short shots.

• Blown Film: In LDPE or LLDPE films, it improves transparency and avoids bubble instability.

• Extrusion: Keeps moisture-sensitive profiles, pipes, and sheets free from lines and roughness.

• Blow Molding: Achieves smoother wall thickness and better appearance in bottles and containers.

• Recycled Plastic Use: Helps manage moisture from post-consumer or industrial plastic scrap.
