why do woven bags use polypropylene as a raw material

In terms of physical properties, polypropylene is non-toxic, odorless and tasteless, and is one of the lightest varieties of all plastics. In terms of mechanical properties, it has high crystallinity and regular structure, so it has excellent mechanical properties. Polypropylene with a larger isotactic index has higher tensile strength, but with the increase of isotactic index, the impact strength of the material has It drops, but it does not change after falling to a certain value. The polypropylene also has good heat resistance, and the product can be sterilized and sterilized at a temperature of 100 ° C or higher, and is not deformed at 150 ° C under the condition of no external force.
In addition, its chemical stability is very good, in addition to being attacked by concentrated sulfuric acid and concentrated nitric acid, it is stable to various other chemical agents, and has good electrical properties and weather resistance.
