UV Masterbatch, 30% Active UV stabilizing ingredients, TPC based

Envalior offers a complete portfolio of thermoplastic polyester elastomers. These materials, sold under the trade name Arnitel®, combine excellent flexibility at low temperatures (down to -50oC) with good heat resistance. Arnitel® has an intrinsic stability against UV, however if high UV performance is required we advise to use the UV stabilization masterbatch Arnitel® E1-UV. The figure on the next page shows the reference UV stability and the effect of adding different amounts of Arnitel® E1-UV to different Arnitel® E types. In the graph the effect of UV ageing according to the UV test PSA D27 1389 at different masterbatch loadings (x-axis) on the half life time (HLT) of the elongation at break of ISO 527 1BA tensile bars is given. HLT is defined as the time point where the elongation is 50% of the original value. Arnitel® E1-UV can be used for injection molding and extrusion applications. It is based on an Arnitel® carrier and shows good dispersion in any Arnitel® type.
