Is PC material a new material? Is it poisonous?
PC material (polycarbonate) is a thermoplastic engineering plastic that is non-toxic when used in normal compliance. It may release toxic substances only at high temperatures, when exposed to organic solvents, or when using inferior raw materials.
PC (Polycarbonate) belongs to the engineering plastics category of plastics. It is basically non-toxic when used in normal compliance. However, there is a risk of releasing harmful substances when exposed to high temperatures, aging or when exposed to corrosive media. The basic attributes confirm that PC is polycarbonate. It is one of the more widely used engineering plastics at present. It has the characteristics of high impact resistance, low temperature resistance, and good light transmission. It is commonly used in water cups, home appliance casings, automobile interiors, electronic component casings and other scenarios.
PC plastic itself has basically no acute toxicity when used in normal compliance, but it is necessary to distinguish between residual monomers that are not fully polymerized, processing by-products and use scenarios to limit the core source of toxicity.(1) The chemical name of the bisphenol A monomer that is not fully polymerized is polycarbonate, and the synthetic raw materials are bisphenol A and diphenyl carbonate. If the polymerization is insufficient during the production process, free bisphenol A will remain.
PC (Polycarbonate) is a thermoplastic engineering plastic. It has no obvious toxicity to the human body when used in normal compliance, but may release harmful substances under high temperatures, improper use, or substandard materials. The material properties of PC PC, namely polycarbonate, are one of the five general engineering plastics. They are classified as thermoplastics in the general category of plastics. They have the advantages of impact resistance, good light transmission, and stable size. They are widely used in consumer electronics, food packaging, building materials, auto parts and other fields.
The category attribute of PC material PC is full of polycarbonate. It belongs to the general category of thermoplastic engineering plastics. It is one of the five major general engineering plastics and belongs to the category of plastic materials.
The main material used in Fuguang plastic cups is polycarbonate (PC), which is a non-toxic plastic. However, when PC plastic cups are exposed to high temperatures, they can decompose and release bisphenol A (BPA). If bisphenol A enters the human body, it may not be effectively excreted. As it accumulates to a certain extent, it may have a negative impact on human health.
What do pp, pe, and pc in plastic represent?
1. PP stands for polypropylene, PE stands for polyethylene, and PC stands for polycarbonate. Polypropylene: It is a member of the polyolefin plastic family and is known for its strength and transparency. It has good chemical resistance, luster and transparency, good insulation properties, is light and strong, is convenient to process, and is affordable. Therefore, PP is often used in fields such as food packaging and tableware.
2. Polyethylene (PE): This is a widely used plastic with good chemical stability and corrosion resistance. It is often used to make packaging bags, plastic films, etc. Polypropylene (PP): Polypropylene is a plastic with good heat resistance and is often used to produce microwave oven lunch boxes, plastic wrap, etc. Polystyrene (PS): Polystyrene has good thermal and chemical stability and is often used to make disposable tableware, containers, etc.
3. PP is polypropylene, PE is polyethylene, and PC is other plastic. Relatively speaking, PP is resistant to high temperatures and is safer. There are numerical signs under the plastic products, which are as follows: Number 1 PET (polyethylene terephthalate), a container made of this material is a common plastic bottle for holding soda, also commonly known as the "Baote bottle". Common mineral water bottles, carbonated beverage bottles, etc. Heat resistant to 70 ° C and are easily deformed, and substances harmful to the human body melt out.
4. Polyethylene (PE) is also a polyolefin plastic. It has luster and is partially transparent or translucent. Polyethylene is a good insulator, light and strong, simple processing and low cost. Polyethylene is resistant to chemical attack and easy to color. Some varieties are also resistant to low temperatures and are often used to make daily necessities such as plastic bags and bottles. Polycarbonate (PC), commonly known as bulletproof glue, is an engineering plastic.

What does pc stand for is written on the bottom of the cup?
This is the environmentally friendly recycling mark for plastic. PC is the abbreviation of polycarbonate Polycarbonate. 7 means that it is not a common plastic. Since polycarbonate does not belong to the material range of 16 above, the number marked in the middle of the triangle of the recycling mark is 7. At the same time, in order to facilitate sorting during recycling, mark the material name PC next to the recycling mark.
The water cup marked 58 on the bottom indicates that it is made of PC (polycarbonate) material. The 58 here means that the polycarbonate content in the cup raw material is 58%. This material is safe from light and at room temperature. The 58 mark indicates that the PC material used in the water cup contains 58% polycarbonate, meets health standards and is suitable for use as a teacup.
PC is a polycarbonate cup with a heat deformation temperature of 135°C, so PC cups can be used at temperatures below 135 ° C. However, it is better not to use a PC cup to hold hot water, because a cup made of PC material may precipitate bisphenol A at high temperatures, which is harmful to the body. If you want to hold high-temperature water, it is better to buy a cup with the pp symbol.
The bottom of the water cup says PC stands for the water cup. The material of the water cup is PC plastic. The following is a detailed explanation of the material of PC: Material definition: PC, or polycarbonate, is a colorless and transparent thermoplastic that is widely used in various products due to its excellent impact resistance and transparency.
