A few days ago, yang Zishi changes copolymer of ethylene of ethylene — acetic acid (product of epispastic colophony UE2860TF sells EVA) high end toward Turkey, realize second exit. Come nearly two years, domestic EVA is produced can grow rapid, market competition is intense. For this, yang Zishi is changed with change sell Hua Dong company to strengthen a butt joint, develop overseas market actively. In November 2021, change sell Hua Dong company to begin the exit matters concerned with EVA of foreign arrange with, recommend Yang Zishi actively to change EVA high end product of epispastic colophony UE2860TF, through indefatigable effort, in January 2022 the last ten-day of a month signed export order formally. In producing a course, because EVA high end is epispastic ethylene of acetic acid of colophony UE2860TF product (VA) content is higher, to device stable production brings greater difficulty. It is difficult that Yang Zishi changes EVA device to produce technical personnel to know and go up, straight face is challenged, implement each craft directive strictly, adjust crucial parameter meticulously, finished the manufacturing job that exports a product smoothly by the plan. Via examining, each index accords with the product foreign requirement.
