DPM’s Desiccant Masterbatch is an advanced functional solution designed to eliminate moisture-related issues during the plastic processing stage. Moisture can be present in raw materials, especially recycled resins, fillers, and pigments, leading to defects such as bubbles, silver streaks, and surface imperfections. Our desiccant masterbatch chemically reacts with moisture to neutralize it, ensuring a smooth production flow and high-quality finished goods without the need for expensive pre-drying equipment.
Key Advantages
-
Moisture Elimination: Effectively absorbs moisture within the polymer melt, preventing gas marks, voids, and “fish eyes” on the product surface.
-
Cost & Energy Efficiency: Minimizes or eliminates the need for prolonged pre-drying of resins, significantly reducing energy consumption and production time.
-
Enhanced Surface Quality: Improves the smoothness, gloss, and structural integrity of the final product by ensuring a dense and uniform polymer matrix.
-
Optimized for Recycled Materials: Acts as an essential additive for manufacturers using recycled plastics, which are often prone to high moisture absorption.
-
Process Stability: Ensures consistent melt pressure and flow, reducing material waste and machine downtime caused by moisture-related defects.
Industrial Applications
-
Film Blowing: Essential for manufacturing shopping bags, garbage bags, and agricultural films, ensuring they remain strong and free of visual defects.
-
Injection & Blow Molding: Widely used for household appliances, containers, and automotive parts to ensure a flawless surface finish.
-
Sheet & Pipe Extrusion: Ideal for producing high-durability pipes and sheets where structural stability is mandatory.
-
Recycling Industry: A “must-have” additive for plastic recycling plants to improve the quality of re-granulated pellets.
Product Specifications
-
Recommended Dosage: 1% – 5% (depending on the moisture content of the raw materials).
-
Packaging: 25 kg per PP/PE bag or vacuum-sealed bags to maintain activity.
-
Storage: Store in a cool, dry place. Keep the packaging tightly sealed until use to prevent premature moisture absorption.
