What is PP edge banding?

What kind of material is PP?
To put it simply, pp is engineering plastic, which is the abbreviation of Polypropylene. PP also has a Chinese name, which is called polypropylene. In terms of chemical composition, PP is a crystalline isometric polymer with neatly arranged molecular links. It is also divided into isometric PP (polypropylene) and random PP, as the name suggests, isometric PP is a polypropylene thermoplastic resin with a crystallinity of more than 95% and a molecular weight between 8-150,000, while random PP is polypropylene at room temperature is an amorphous, microviscous white wax with low molecular weight.

Physical properties of PP material
PP material is one of the lightest plastics, which is non-toxic and odorless. From the physical properties, it is easiest to understand what kind of material PP is. It has a relatively large shrinkage rate, so the molded product lacks dimensional accuracy. However, the surface gloss of PP material products is beautiful, which is conducive to coloring products.

Mechanical properties of PP materials
Do you already have a general outline of what material PP is, let's take a look at the mechanical properties of PP material. PP material is a polymer and has a stable internal structure, so PP material has stable mechanical properties. In general, it can maintain a strength of 30MPa, which is much higher than that of polyethylene polymer.

Weather resistance of PP material
What is weather resistance? It refers to the durability of our PP material for outdoor environments. That is, it refers to the ability to withstand sunlight, climate, wind and rain. Now that we know what material PP is, we need to understand its weather resistance. PP material is very sensitive to ultraviolet rays, so its anti-aging performance is not very good, but it can be solved by a certain method.

Thermal properties of PP materials
Thermal performance, as the name suggests, is the heat resistance of PP material. We say that PP material can be melted at high temperatures and has fluidity, but this high temperature is generally unattainable. Because the PP material has good heat resistance, the products made of PP material will not be deformed in the slightest after being scalded with boiling water.
