Packing & Storage
| Packaging | The polypropylene resin is packed in a polypropylene woven bag with an inner coating, and the weight is 25 kg/bag. | ||||
| Storage | Polypropylene resin should be stored in a ventilated, dry, clean and well-maintained warehouse with good fire-fighting facilities. When storing, keep away from heat sources and prevent direct sunlight. It is strictly forbidden to store in the open air. Polypropylene resin should have a storage period, generally no more than 12 months from the date of production. | ||||
| Transportation | It is strictly forbidden to use sharp tools such as iron hooks during transportation and loading and unloading, and should not be thrown. The means of transportation should be kept clean, dry and equipped with a shed or tarpaulin. Exposure to sunlight or rain is strictly prohibited. | ||||

Synthetic Route
| Propylene random copolymer is prepared by simultaneous polymerization of ethylene molecules and propylene molecules. The reactor used is the same as that used to produce PP homopolymers.The ethylene molecule is smaller than the propylene molecule, and the reaction is faster than (about ten times the reactivity) propylene.This weakens the stereotactic properties of the catalyst and increases its activity, resulting in an increase in the amount of random polyacrylonitrile.In order to reduce the formation of this random substance, the reaction temperature needs to be reduced, thereby reducing the activity of the catalyst, and reducing the content of random isomers in the final product to obtain a product with more balanced properties. |
