ZLSIL-K44 Plastic Grade Silica Anti-blocking Agent Product Specification
PRODUCT DETAILS
1. Product Description
ZLSIL-K44 is a synthetic amorphous plastic-grade silica anti-blocking agent presented in white powder form, manufactured via exclusive special processes. Its CAS No. is 112926-00-8 (former CAS No.: 7631-86-9) and EINECS No. is 231-545-4.
Featuring high purity, porous structure and high specific surface area, this product boasts excellent compatibility with plastic resins including PP, PE, PET and PVC. It requires no grinding, features low addition dosage and superior dispersibility, and will not impair the transparency and mechanical strength of plastic films.
Non-toxic and eco-friendly, it contains no volatile substances or precipitates to fully guarantee the quality of packaging products. By reducing exposed molecular chains during polymer processing, it effectively solves molecular chain entanglement between film surfaces to achieve outstanding anti-blocking effect. Meanwhile, it improves film slipperiness, anti-adhesion property and creep resistance, and reinforces film mechanical performance. It serves as an ideal raw material for producing anti-blocking masterbatch for various plastic films.

3. Core Application Advantages
1. High oil absorption for high filling demand
With high DBP oil absorption value, it supports high-proportion filling in anti-blocking masterbatch production. The finished masterbatch is free of agglomeration and precipitation with stable molding performance.
2. Simplify production proceduresIt
can be directly blended with carrier resins without pre-grinding. Its excellent dispersibility cuts down production costs and boosts processing efficiency.
3. Preserve original film core properties
Good compatibility with resin matrix ensures no reduction in film transparency and mechanical strength after addition, maintaining stable appearance and practical performance of finished films.
4. Wide adaptability to diverse processing scenarios
Widely applicable to anti-blocking masterbatch of PP, PE, PET, PVC and other plastic films, suitable for film blowing, cast film, extrusion and other processing technologies. It keeps stable performance after drying below 300℃, perfectly meeting the ultra-low moisture requirement of PET films.
5. Enhance overall film performance
Apart from efficient anti-blocking effect, it optimizes film slipperiness, anti-adhesion and creep resistance, effectively avoiding film sticking and jamming on high-speed packaging lines, and improving stability in film processing and end use.
4. Storage & Operation Guidelines
1. Thanks to high specific surface area, the product easily absorbs moisture and volatile substances in the air. Please store it hermetically in dry, ventilated and cool conditions. The shelf life of unopened goods is 24 months. Application performance test is required before using expired products, which can only be used after passing the test.
2. Take dust-proof measures during loading, unloading, transportation and usage to prevent dust dispersion. The stacking height shall not exceed 10 layers to avoid particle structure damage caused by extrusion and subsequent decline of dispersibility.
3. Properly extend dispersion time during extrusion processing, as equipment extrusion may weaken its dispersing effect. It is recommended to use up the whole batch once opened to prevent performance degradation of anti-blocking and dispersing properties caused by moisture absorption.
