                                        It can be used in polyester, epoxy resin, intermediate of organic synthesis of pesticide, dye, medicine, plasticizer, fireproof paint, etc.

                                        4、 Packaging
                                        Manual packaging technology is adopted. Electronic scale is used for automatic measurement, and packaging specifications are specified according to the requirements of the other party.
                                        Class I: it is accurately measured by 25 + 0.2kg/bag. The packaging bag is polypropylene set packaging bag, which has good strength, is not easy to be damaged, can prevent moisture, corrosion and save cost.
                                        Class II: it is accurately measured by 400 + 0.5kg/bag. The packaging bag is polypropylene container bag, which has good strength, is not easy to be damaged, can prevent moisture, corrosion and save cost.
                                        Three categories: accurate measurement by 500 + 0.5kg/bag, the packaging bag is polypropylene container bag, which has good strength, is not easy to be damaged, can prevent moisture, corrosion and save cost.
                                        Type IV: accurately measured by 600 + 0.5kg/bag, polypropylene container bag is used for packaging bag, which has good strength, is not easy to be damaged, can prevent moisture, corrosion and save cost.
                                        Category 5: it is accurately measured by 900 + 0.5kg/bag. The packaging bag is polypropylene container bag, which has good strength, is not easy to be damaged, can prevent moisture, corrosion and save cost.
                                        Category 6: it is accurately measured by 1000 + 0.5kg/bag. The packaging bag is polypropylene container bag, which has good strength, is not easy to be damaged, can prevent moisture, corrosion and save cost.

                                        5、 Storage and transportation
