PP Plastic Material=”https://2lians.com/products/pp-white-sheet-regrind”> are usually featured in transparent white color, not as turbid as PE plastic. In addition, it is also a colorless, odorless or toxic substance to human and animal health. Therefore, in production, it is often mixed with colorful beads to create eye-catching and attractive
Physical properties PP White Sheet Regrind:
PP resins have the highest heat resistance of most plastics, specifically from 130 °C to 170 °C. Meanwhile, HDPE resins can only withstand temperatures of 120 °C for a short time. And LDPE resins can only safely meet up to 95 ° C in a short time. However, in terms of flexibility, PP is somewhat inferior to PE. It is quite stiff and cannot be stretched and another drawback is its tendency to tear, not able to withstand heavy volumes. It can be said that, with only a small cut or a slight tear, the packaging from PP White Sheet Regrind will quickly deteriorate.
Chemical properties PP White Sheet Regrind:
When burned, polypropylene plastic smells like rubber and often produces a blue flame. Like PE,PP Plastic Product are not water-repellent, as well as gas and grease when exposed. This is a chemically inert plastic and has a melting point of up to 165 ° C, which is an ideal standard compared to PE.
Chemical stability Due to the flexible H atom at C level 3, it is easy to oxidize and age. PP has no stabilizers
Under diffuse light, the properties remain stable for 2 years. -With direct light, after only a few months will be brittle and destroy immediately. PP has a stabilizer (or use 2% soot) under direct light (ultraviolet light) – after 2 years, the properties are unchanged and stable for 20 years. Resistant to sunlight.
Application of PP White Sheet Regrindin life
In life, PP Plastic is used to make food packaging. And especially, these single-layer boxes can be put into the microwave in a short time about 2-3 minutes. With high mechanical and chemical inertness makes PP a safe material, but the color is quite transparent so aesthetics are not high.
