Polymer grade organic montmorillonite CAS 1318-93-0

Introduction

The microscopic morphology of NANOLC-KT301 is an aggregate of nano-sheet units. Through surface modification and ion exchange, the surface free energy of NANOLC-KT301 is reduced, and the compatibility with the polymer matrix is ​​enhanced. After the fine nano-organic montmorillonite flakes are composited with polymers, the mechanical properties, heat resistance, gas barrier properties, chemical resistance, anti-virus, thermal stability, UV aging performance, environmental protection and flame retardant properties of the polymer are greatly improved.

Application 

White or colored cable materials; flame retardant materials for household appliances; degradable reinforcement materials; barrier and fresh-keeping films; 3D printing materials, etc.

Specification:

Usage:
Maleic anhydride or acrylate grafted PP, PE, EVA are usually used as compatibilizers and mixed with base resins, inorganic flame retardants and appropriate amounts of organic montmorillonite and other additives, and twin-screw melt extrusion granulation is used to make halogen-free flame-retardant cable materials or mechanical properties improvement materials.
It can also be made into 50%6 organic montmorillonite masterbatch, which contains 50% organic montmorillonite, about 30% base resin, 20%6 compatibilizer and additives, and then added to polyolefins, EVA, TPO and other materials for injection molding, extrusion, blown film and other molded products, which play a role in improving the mechanical properties, barrier, heat resistance, synergistic flame retardancy of materials. The general addition amount of masterbatch is 5-8%.
Try to use a screw structure with a large length/diameter ratio and high shear strength for the twin-screw extruder used. The melting temperature during the extrusion process should not be too high to maintain a high viscosity of the polymer melt and ensure that the polymer receives a strong shearing effect during the extrusion process to facilitate the exfoliation and dispersion of the montmorillonite flakes.
