Category of PC(polycarbonate)

PC (polycarbonate) belongs to P7

1.PET (polyethylene terephthalate), a container made of this material, is a common plastic bottle for soda, also known as "Bottle bottle".

Common mineral water bottles, carbonated beverage bottles, etc. It is easy to deform when it is heat-resistant to 70 C, and has substances harmful to human body melting out. The carcinogen DEHP may be released from No. 1 plastics after 10 months. Don't put it in the sun in the car; don't fill it with alcohol, oil, etc.

2.HDPE (High Density Polyethylene), detergent, shampoo, bath milk, edible oil, pesticides and other containers are mostly made of HDPE. Containers are mostly opaque and feel like wax.

Common white medicine bottles, cleaning supplies, bath products. Don't use it as a water cup or as a storage container for other things. Don't recycle if it's not thoroughly cleaned.

3.PVC (polyvinyl chloride), mostly used in the manufacture of water pipes, raincoats, schoolbags, building materials, plastic film, plastic boxes and so on.

Common raincoats, building materials, plastic film, plastic boxes, etc. Because of its excellent plasticity and low price, it is widely used and can only resist heat at 81 C. It is easy to produce bad substances at high temperature, and seldom used in food packaging. Difficult to clean and easy to residue, do not recycle. Don't buy drinks if they are packed.

4.LDPE (Low Density Polyethylene), plastic bags everywhere are mostly made of LDPE.

Fresh-keeping film, plastic film, etc. When high temperature occurs, harmful substances are produced. When poisonous substances enter human body with food, they may cause breast cancer, congenital defects of newborns and other diseases. Don't put the film in the microwave oven.

5.PP (polypropylene) is used to make water cans, garbage cans, baskets, food containers for microwave ovens and so on.

Common soybean milk bottles, yogurt milk bottles, juice beverage bottles, microwave oven lunch boxes. The melting point is as high as 167 C. It is the only plastic box that can be put into the microwave oven. It can be reused after careful cleaning. It should be noted that some microwave oven lunch boxes are made of No. 5 PP, but the lid of the box is made of No. 4 PE. Because PE can not withstand high temperature, it can not be put into the microwave oven with the box body.)

6.PS (polystyrene), because of its low water absorption, is mostly used to make building materials, toys, stationery, rollers, as well as drink cupboxes or disposable tableware in fast food stores.

(Common bowl-packed noodle boxes, fast food boxes. It should not be put into the microwave oven to avoid releasing chemicals due to excessive temperature. After loading acid (such as orange juice) and alkaline substances, they will decompose into carcinogens. Avoid packing hot food in fast food boxes. Don't cook instant noodles in a microwave oven.)

7.Other. Common PC categories, such as kettles, space cups, milk bottles. Department stores often use water cups of this material, PA class, or nylon, mostly for the internal parts of fibre textiles and some household appliances and other products. PC is easy to release toxic substance bisphenol A at high temperature, which is harmful to human body. When using, do not heat, do not direct sunshine.)
