PVDF materials (polyvinylidene fluoride) are in serious shortage due to the outbreak of new energy vehicles and photovoltaic industry, and the price is soaring! Its excellent performance shines brightly in lithium battery electrode and diaphragm adhesive, excellent performance in photovoltaic film and water treatment film, fluorocarbon coating, injection molding, lamination, etc., making it widely used in automobile manufacturing, construction, electrical and electronic, semiconductor, water treatment, food, pharmaceutical, bioengineering, chemical industry and other industries! The pain point of PVDF production industry - the treatment of a large amount of PVDF waste containing paraffin, the patented technology of Changxian New Material has been industrialized to achieve the complete separation of PVDF and paraffin and the purification treatment of PVDF, the chain expansion of low molecular weight to improve the melt index, the realization of waste recycling.
