Is pp material resistant to high temperature? Confusion from the majority
It is very important for physical health, and it is also an indispensable thing. When we choose water glasses, there are generally materials such as glass, silicone, plastic and PP, but which of the many materials is more suitable Are people at ease? This is a puzzling problem in the hearts of thousands of people, so let's explain the PP material in detail. Is PP material resistant to high temperature? Let’s uncover it.
1. Is PP material resistant to high temperature?
In fact, the PP material itself is a natural, cylindrical particle. The particles are very smooth. The size of the particles can be 2mm to 5mm in any direction. The PP material is odorless, non-toxic, and free of any mechanical impurities. And because PP material is made of polypropylene, it has very good heat resistance. The finished product can be sterilized and sterilized at a temperature of up to 100 ℃ or more, and it can be affected by any external force. It will not be deformed when the temperature is as low as 150℃. However, its embrittlement temperature is generally -35℃, and embrittlement will occur below -35℃, so its cold resistance will not be as good as polyethylene. From this we can see that the pp material has good heat resistance, and the products made of the pp material will not be deformed even after being boiled in water.
2. What are the characteristics of PP material?
1. Physical properties
The PP material is a very light-weight plastic, which is non-toxic and odorless, and the shrinkage rate will be relatively large, but the surface gloss of the PP material is very beautiful and very conducive to the coloring of the product.
2. Mechanical properties
PP material is a kind of high polymer, its internal structure is very stable, generally can maintain the strength of 30MPa, will be much higher than polyethylene polymer, so PP material has very stable mechanical properties.
3. Weather resistance
The PP material's ability to withstand sunlight, climate, and air drying can produce certain durability and is very sensitive to ultraviolet light, so its anti-aging properties may be poor, but it is not impossible to solve.
4. Thermal performance
Refers to the heat resistance of the PP material. The products made of the PP material will not be deformed even if they are hot.
In summary, PP material is very resistant to high temperature, and it is non-toxic and tasteless, so you can use the products made with it with confidence
