PP plastic is resistant to high temperatures. Under normal circumstances, the maximum temperature it can withstand is around 120 degrees to 150 degrees. If used at this temperature for a long time, only slight deformation will occur, and its melting point is as high as 167 degrees. Lunch boxes and tableware made of pp material can be directly heated in a microwave oven, or can be sterilized by boiling in water. These are all manifestations of its high temperature resistance, and they can be reused after heating.

What should you pay attention to when purchasing pp material products

1. Raw materials

When purchasing pp material products, you must understand the raw materials of the product clearly. When many regular manufacturers produce pp material products, they generally use pure pp materials for production. However, some pp material products are not produced using pure pp materials, because some manufacturers will add additives during production in order to save production costs. Some other materials. Generally speaking, PP material products that are not harmful to human health and are food grade are the best.

2. Appearance

When purchasing pp material products, be sure to observe the appearance of the product in detail. Under normal circumstances, the appearance of high-quality pp material products is generally transparent or translucent, and generally more glossy, more beautiful, and free of burrs.

How to choose pp water pipes

1. Look at the shape. When purchasing water pipes, you can check whether the shape of the water pipe is correct and whether it is deformed or twisted. If the surface of the water pipe is flat and the color is uniform. Regular and qualified water pipes have clear trademarks, specifications, and production dates printed on the outer walls of the pipes. When purchasing a hookah, check to see if it has a health license. This type of water pipe cannot be used without a sanitary permit.

2. From the smell, most water pipes are made of plastic, and plastic water pipes are manufactured through a mechanical extrusion process. However, now some companies are using toxic plastics in their tube production to make huge profits or their production process is not good. When water pipes made of toxic plastic are used, toxic substances in the water pipes can easily enter the human body through the water, which can ensure people's water safety. Substandard and inferior water pipes generally produce pungent odors.

3. When people buy water pipes, they bend them by hand. If the water pipe can be bent easily without breaking, it means the water pipe is of high quality. For example, good quality PPR pipes can now be bent into a circle. It will not break. If the plastic water pipe breaks and becomes brittle when bent, it means that the quality of the water pipe is relatively low. You can also take a small piece of plastic water pipe and put it into high-temperature water to see the degree of hardening. If the water pipe becomes brittle at a temperature of 60 degrees, Soft indicates that the water pipe is of poor quality.
