To make it clear pp edge banding, let's start with his raw material pp.
What material is pp
Simply put, 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 isotactic polymer with very regular molecular chain links. It is also divided into isotactic PP (polypropylene) and random PP. As the name suggests, isotactic pp is a thermoplastic resin with a polypropylene crystallinity of more than 95% and a molecular weight between 80,000 and 150,000, and random PP is Polypropylene is a non-crystalline, slightly viscous white wax at room temperature with a low molecular weight.
pp material physical properties
PP material is a kind of lightweight plastic, which is non-toxic and tasteless. It is easy to understand what pp is from the physical properties. Its shrinkage rate is relatively large, so the precision of the size of the molded product is lacking. However, the pp material product has a beautiful surface and is good for coloring the product.
pp material mechanical properties
Do you have a rough outline of what pp material is? Let's take a look at the mechanical properties of pp material. The pp material is a high polymer, and the internal structure is stable, so the pp material has stable mechanical properties. Under normal circumstances, it can maintain a strength of 30MPa, which is much higher than that of polyethylene polymer.
Weather resistance of pp material
What is weatherability? It refers to the durability of our pp material to the outdoor environment. It means the ability to withstand sunlight, climate, wind and rain. Now that we know what pp is, we must understand its weatherability. The pp material is very sensitive to ultraviolet rays, so its anti-aging performance is not very good, but it can be solved by certain methods.
Thermal performance of pp material
Thermal performance, as the name implies, is the heat resistance of pp material. We say that pp material can be melted at high temperature and has fluidity, but this high temperature cannot be reached under normal circumstances. Because pp material has good heat resistance, products made of pp material will not be deformed even after boiling.
After understanding the material of pp edge banding, it is easier for us to understand why pp edge banding will gradually reach people`s recognition, because it has good chemical resistance, excellent heat resistance, and is the only thing that can be boiled in water. And can withstand the disinfection environment of more than 100 ℃ plastic varieties. The coloring performance of PP is better than that of ABS, and it is a safe and environmentally friendly material.
