Performance management data is stored and retained through the HR systems. Also, our CESA™ Additive Masterbatches are utilized for solar back sheets to enhance the halogen-free mono material structure and protect against voltage breakdowns. Through this data, we create safety data sheets, customer certification statements for appropriate use and product safety improvements.
