Packing & Storage
| Packaging | Polypropylene resin is packaged in a polypropylene woven bag with an inner film, and the weight is 25 kg/bag | ||||||||
| Storage | Polypropylene resin should be stored in a ventilated, dry, clean warehouse with good fire-fighting facilities. When storing, it should be kept away from heat sources and direct sunlight, and it is strictly forbidden to stack in the open air. Polypropylene resin should have a storage period, generally no more than 12 months from the date of production. | ||||||||
| Transportation | Polypropylene resin is non-hazardous. It is strictly forbidden to use sharp tools such as iron hooks during transportation and loading and unloading, and do not throw them. The means of transport should be kept clean, dry and equipped with a shed or a tarpaulin. Do not expose to the sun or rain | ||||||||

Synthetic Route
| It is formed by the polymerization of vinyl acetate in the presence of acetic acid. The degree of polymerization is appropriate from 250 to 600. After the polymerization is completed, the remaining trace catalysts (usually peroxides), monomers and/or solvents in the resin are removed by vacuum drying, steam stripping, washing or combined treatment.In the presence of acetic acid, benzoyl peroxide is used as the initiator and vinyl acetate is used for bulk polymerization; or polyvinyl alcohol is used as the dispersant, and solution polymerization is carried out in a solvent at 70~90℃ for 2~6h (the degree of polymerization is controlled at 250~600 is appropriate) to obtain the product. |
