How to choose the materials of plastic products?
Feb 01, 2019

The choice of materials for plastic products is very important. It not only determines the quality of plastic products, but also determines the environmental performance. What choices do plastics have in the raw materials of plastic products? Commonly used sheets are: PVC, PET, PP, PS and flocked sheets, gold-plated sheets and anti-static sheets based on this.

PVC: The most commonly used plastic material, soft, strong toughness, good plasticity, can be made into transparent and various colors, commonly used in transparent PVC packaging electronics, cosmetics, toys and other products.

PET (A-PET): hard, tough, high strength, bright surface, environmentally friendly, non-toxic, transparent and multi-colored sheets. The disadvantage is that PET high frequency heat sealing is more difficult, and the price is much more expensive than PVC. This material is often required to replace PVC with high-grade and environmentally friendly users.

PS: low density (light weight), environmentally friendly and non-toxic, very good plasticity, poor toughness and brittleness, can not be made into transparent materials, so it can only be made into the bottom type of plastic, because it is easy to crack, such plastic is not suitable for recycling

PP: The material is particularly soft, with good toughness, environmentally friendly, non-toxic and high temperature resistant. It is often packaged as a catering appliance or other high temperature resistant product; however, it has poor plasticity, is difficult to process, has poor surface gloss, and the color changes during processing. shallow.

PET-G: Physical properties are similar to A-PET, but can be heat sealed at high frequency, which is 80% more expensive than A-PET.
