TECHNICAL DATA SHEET
XTRACON WS
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.

The Series Consists of Five Grades with the Following Base Resins
Xtracon WS-100Polyester Urethane
Xtracon WS-200Polyether Urethane
Xtracon WS-300Ether/Ester Urethane
Xtracon WS-400Aliphatic Polyether Urethane
Xtracon WS-500Rigid Urethane
