PP plastic materials 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 Jumbo Bag Reusable:
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 plastic 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 will quickly deteriorate.
At room temperature, the PP Film does not dissolve in organic solvents, even after prolonged exposure, but only in aromatic and chlorinated carbides. At temperatures above 80 ° C, PP begins to dissolve in the two solvents. A large crystalline polymer is more chemically stable than a small crystalline polymer. Practical PP is considered not absorbing water, dehumidification level.
High mechanical strength (tear strength and tensile strength), quite hard, strong, not as flexible as PE, not stretched so it is made into yarn. Especially likely to tear easily when there is a cut or a small puncture. Polypropylene is colorless, odorless, tasteless, non-toxic. Polypropylene burns brightly with a light blue flame, has a flexible flow, has a burning smell similar to that of rubber.
Chemical properties PP Jumbo Bag Reusable:
When burned, polypropylene plastic smells like rubber and often produces a blue flame. Like PE, PP plastic products 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 Jumbo Bag Reusablehas 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.
