1) How to choose polyolefin Fluorescent Whitening Agent?
2) How to choose PVC fluorescent Whitening Agent?
It is worth noting that the same fluorescent whitening agent has different whitening effects on rigid polyvinyl chloride (R-PVC) and flexible polyvinyl chloride (FPVC). A bisbenzoxazole or phenylcoumarin group is commonly used for polyvinyl chloride. When the polyvinyl chloride powder, the heat stabilizer and the fluorescent whitening agent are mixed and dried, the fluorescent whitening agent is uniformly distributed. For flexible PVC, OBA dissolves or disperses in the plasticizer. It is best to add FWA in the form of a master batch. Fluorescent whitening agents and plasticizer masterbatches or OBA and PVC masterbatches are used when transporting PVC.
