Alloy Mica SEM micrograph

Zero α® Alloy Mica

A5130



Introduction

Alloy-Mica Zero α® is a kind of inorganic material, which in appearance of flake under microscope, with the feature of high aspect ratio and low hardness. For different organic compatibility, the surface of flakes is treated with various silane as coupling agent; then special features of this product is able to be compatible to aromatic polymers, ex. Nylon6, Nylon 66, Nylon HTN, Nylon 46, PPO…etc.


★To improve the performance of dispersion in compound system.
★To enhance the properties such as: HDT, flame retardant, heat conductivity, anti-yellow aging weathering, and increase flexural strength…etc.

Reamrks

Compounding Application:

  1. 1.When using A5130 as filling powder, a twin-screw extruder, which equipped with a side-feeding system in front of extruder, should be applied.
  2. - A5130 powder feed in system via side-feeding system;
  3. - If there is no side-feeding system in the front of extruder, two separated feeders should be prepared that one for resin while A5130 filling powder, the other.

  4. 2. In order to avoid the return flow of fed resin, the upstream temperature of extruder should be 5~10℃ higher than downstream.
  5. 3. A5130 filling powder should be fed in system after the plastic feeding process is stable.
  6. 4. The recommend dosage of A5130 is 12 wt%~35 wt% of composite plastic.
