TECHNICAL DATA SHEET|
Polyurethane Weathering Stabilizer Concentrates
Xtracon WS series are concentrates for use in thermoplastic polyurethane
or polyurethane alloy applications where resistance to oxidation
and UV degradation is required. Marked improvement in yellowing
and physical property retention under severe weathering conditions
can be achieved in conventional aromatic (MDI) based resins,
and outstanding retention of properties and color is obtained
in aliphatic based TPU. Use level will vary with the application but
1-5 pphr has been found to be useful for many resins.
