Polyethylene (PE), the world's most widely used general-purpose plastic, is extensively applied in high-transparency films, pipes, and injection packaging. During high-temperature extrusion (like film blowing or casting) or post-consumer recycled (PCR) PE pelletizing, polymer chains inevitably undergo thermo-oxidative degradation, releasing pungent short-chain fatty acids and aldehydes/ketones. Meanwhile, PCR systems often contain complex sulfur and nitrogen odors from pesticides or detergent residues. High-end film products are extremely sensitive to optical clarity and heat-sealing performance, and traditional deodorizing methods often ruin the matrix properties of films.
To overcome these challenges fundamentally through polymer rheology and thermodynamics, this product is meticulously crafted as a high-performance reactive dry-blend deodorizer tailored for non-polar PE systems. It combines targeted chemical complexation with acid-absorbing catalytic mechanisms to accurately lock polar stench molecules and neutralize degradation acids from the source. Utilizing an original macromolecular anchoring and nanoscale isolation architecture, it grants the powder ultimate dispersibility and superior polymer compatibility. While powerfully eliminating odors, it does not interfere with PE's crystallization process, perfectly preserving the high light transmittance, heat sealability, and tensile strength of films. It is the premier odor solution for high-end blown films, food-grade packaging, and bulk PE recycling.
