PP material characteristics

  1. Physical Properties of PP Material
    PP material is one of the lightest plastics, inherently non-toxic and odorless. Its physical properties provide the easiest way to understand what PP material is. It has a relatively large shrinkage rate, which results in a lack of precision in the dimensions of molded products. However, PP material products have a glossy and aesthetically pleasing surface, which is conducive to coloring the products.

  2. Mechanical Properties of PP Material
    Have you already formed a rough idea of what PP material is? Let's take a look at its mechanical properties. PP material is a high polymer with a stable internal structure, therefore, it possesses stable mechanical properties. It can generally maintain a strength of 30MPa, which is much higher than polyethylene polymers.

  3. Weather Resistance of PP Material
    What is weather resistance? It refers to the durability of our PP material against outdoor environments. That is, its ability to withstand sunlight, climate, and wind and rain. Since we know what PP material is, we should also understand its weather resistance. PP material is very sensitive to ultraviolet light, so its anti-aging performance is not very good. However, this can be addressed through certain methods.

  4. Thermal Properties of PP Material
    Thermal properties, as the name suggests, refer to the heat resistance of PP material. We say that PP material can melt and become fluid at high temperatures, but this high temperature is generally unattainable under normal circumstances. Because PP material has excellent heat resistance, products made from PP material will not deform even when scalded with boiling water.

Is PP material toxic

Recently, someone asked me if PP plastic is toxic. Today, I will tell you that PP plastic itself is non-toxic. It is commonly used in the production of plastic bottles, plastic bags, plastic films, and other processed items. However, during the processing of PP plastic, various chemical additives such as plastic pigments, plastic fillers, and plasticizers are added, and these chemical additives are toxic.

I would like to advise everyone here that if you intend to use plastics at high temperatures, it is best to avoid them. This is because high temperatures can cause the chemical additives in plastic products, such as plastic pigments, plastic fillers, and plasticizers, to volatilize, making them toxic. When choosing plastic cups or other plastic products, be sure to purchase from reputable merchants.

PP self-adhesive label paper

PP adhesive label paper has a matte white color, with a tough material, good resistance to compression, and good moisture and water resistance; Its cost is lower than PET, and it can be used in combination with mixed and resin based carbon ribbon printing. It has thermal transfer printing performance and is widely used in applications such as electronic components and daily chemical products.
