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 consists of a UV additive change, there should not be a significant change in the properties. This data is based on 2 production lots. Feb/9/2023 - Lidina - Updating physical properties only, due to some differences noticed by customer. 12.01.24 Change of the Lifetime of Storage . Peter Biller
