ZLSIL-K39 Plastic Grade Silicon Dioxide Anti-blocking Agent Product Introduction

PRODUCT DETAILS

1. Product Description

ZLSIL-K39 is synthetic amorphous plastic-grade silicon dioxide anti-blocking agent in fine white powder form, produced 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 porous structure and high specific surface area, it boasts excellent compatibility with plastic resins. It can be used directly without grinding, with 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, effectively ensuring the quality of packaging products. It reduces exposed molecular chains during polymer processing and avoids macromolecular chain entanglement between contacted films, fundamentally solving film blocking issues. It also lowers adhesion force during friction, improves film slip property, enhances anti-blocking and anti-creep performance of films on high-speed packaging lines, and reinforces film toughness. It is widely applicable to the production of anti-blocking masterbatches for PP, PE, PET, PVC and other plastic films.

3. Core Application Advantages

1.Suitable for multi-substrate masterbatch production

Directly applicable to prepare anti-blocking masterbatches for PP, PE, PET and PVC plastic films. No extra grinding is required, simplifying production procedures and raising processing efficiency.

2. Low dosage with remarkable effect

Supported by high specific surface area and porous structure, excellent anti-blocking effect can be achieved with a small amount of addition. It disperses evenly in masterbatches without agglomeration, and causes no adverse impact on subsequent processing performance.

3.Stable finished product quality

It keeps original transparency and mechanical strength of plastic films unchanged. Free of precipitates, it will not contaminate packaged contents, fully meeting basic quality standards of various packaging products.

4. Meet special processing standards

To satisfy the ultra-low moisture requirement for PET film production, the product can be dried below 300℃ with no performance degradation after drying, perfectly conforming to PET film processing criteria.

5. Improve production line efficiency

It greatly strengthens anti-blocking capacity of films in high-speed packaging production, reducing film jamming and adhesion problems. Its outstanding anti-creep property ensures stable continuous high-speed production.

4. Storage & Operation Instructions

1.With high specific surface area, the product easily absorbs moisture and volatile substances in the air. Store it hermetically in dry, ventilated and cool places. The shelf life of unopened goods is 24 months. Performance test is required before application if expired.

2.Take proper protective measures to prevent dust scattering during loading, transportation and usage. Stack height shall not exceed 10 layers to avoid compression damage to its dispersibility.

3.Prolong dispersion time appropriately during extrusion processing for better dispersion effect. It is recommended to use up the product immediately after opening to prevent decreased anti-blocking performance caused by moisture absorption.
