This concentrate is designed specifically for those outdoor film applications requiring protection from both ultra violet light and thermal/oxidative factors. UV protection is provided by a Hindered Amine Light Stabilizer (HALS) which also gives a significant degree of thermal protection. The thermal/oxidative protection comes from a hindered phenol/phosphite blend. The carrier resin for 1954 UV/AO PEC was selected for ease of let down and broad compatibility with other polyolefins. Description/Features: Market: Processing Method: Note: Let down ratios to be used will be determined by the specific application. Factors of film thickness, type of exposure, let down resin and product life expectancy must be considered. Typical ratios may vary from 10:1 to 40:1 depending on the specific end product requirements. 1954 is acceptable for FDA applications depending on end use.
