The characteristics and quality influencing factors of PE self-adhesive film

Introduction: PE self-adhesive films are made by high-pressure and low-pressure raw materials plus high-quality tackifier masterbatch through three-layer co-extrusion blow molding. One layer of the film is made of self-adhesive material, so that it can be self-adhesive without coating glue.

The characteristics and quality influencing factors of PE self-adhesive film

PE self-adhesive films are made by high-pressure and low-pressure raw materials combined with high-quality tackifier masterbatch through three-layer co-extrusion blow molding. One layer of the film is made of self-adhesive material, so that it can be self-adhesive without coating glue.

Characteristics of PE self-adhesive film PE self-adhesive film has the characteristics of stable viscosity, no pollution, no adhesive residue, moisture proof, anti-corrosion, strong anti-tension, and good extension effect. Can protect the surface of the goods smooth and smooth, reduce surface oxidation, avoid scratching hard objects, convenient transportation and storage, suitable for wire pipe dressing, high-tech plastic products.

Factors affecting the quality of PE self-adhesive film 1. Crystallinity of PE material: The lower the crystallinity, the better the adhesiveness. The higher the crystallinity, the worse the viscosity.

2. Flexural modulus of PE material: The lower the flexural modulus, the softer the PE protective film, the easier the low molecular weight of PE penetrates into the surface of the object, and the stronger the paste is.

Graphite electrodes are used mainly in ladle furnaces, electric-arc furnace steelmaking, Yellow phosphorus furnace, 
Industrial silicon furnace or melting copper. They are presently the only products available that have the high levels
 of electrical conductivity and the capability of sustaining the extremely high levels of heat generated in this 
demanding environment. High Quality Needle Coke in HP&Uhp Graphite Electrode, to ensure the application for the
 electrodes are more perfect. Graphite electrodes are also used to refine steel in ladle furnaces .
kneading, forming, baking and pressure impregnation, graphitization 
and then precision machined with professional CNC machining. Our
 electrodes have the characteristics of low resistivity, good electrical 
conductivity, low ash, compact structure, good anti oxidation and 
high mechanical strength, and then they are the best conductive 
material for electric arc furnace and smelting furnace.

Our company is specilized in the feild of Graphite Electrode for 27 years in
 China. We have full experiences in exporting RP Hp Uhp Graphite Electrode
 to Russia, Egypt, Pakistan, Bangladesh, Italy, Oman, Malaysia, etc..
