Jan 6th, 2021 - Zarif edited the TDS to change from PE399-101 (Old UV Package) to PE399-102 DP (New UV Package) basic properties to reflect the new product. Because it only consist of a UV additive change, there should not be a significant change in the properties. This data is based on 2 production lots.
