Abstract
How to choose an easily-opened masterbatch? For masterbatch producers, the key is: how to choose a suitable masterbatch for themselves? In addition to its excellent opening and anti-blocking effect, there are the following points:
How to choose easy-opening and smooth masterbatch? For masterbatch producers, the key is: how to choose the right easy-opening masterbatch? In addition to its excellent easy-opening and anti-blocking effect, there are the following points:
1. Optical properties: In order to achieve better transparency and lower haze, the selection of easy-opening and smooth agent should be similar to the refractive index of the resin (1.49), with a narrow particle size distribution and appropriate particle size, so that a small amount can achieve the required easy-opening effect.
2. Dispersibility: The particle size of the anti-blocking agent is crucial. The smaller the particles, the more difficult it is to disperse. The larger the particle size, the more it will affect the surface and optical properties of the film. The particle size of the anti-blocking agent is usually 2-10 microns, which requires the masterbatch producer to have high-dispersion twin-screw extruder equipment and rich experience in masterbatch dispersion production.
