Product Highlights

• SperseStab systems represent a highly effective light and thermal stabilizer package for use in both thermoplastic polyurethanes (TPU) as well as rigid and plasticized PVC.
• For TPU it finds application for polymers produced from either aliphatic or aromatic isocyanates. The TPU Polymer may further be derived from polyether or polyester polyols.
• The SperseStab™ 4866 system incorporates a strong and permanent UV-B absorber for long term UV protection without the imparting color and ideally optimized for Urethanes.
• This system can also be incorporated into adhesive systems such as MS Polymers and SPURS.
• The SpeseStab system also includes a highly active and permanent antioxidant / radical trap which does not contribute to color and is ideally suited for PVC and TPU systems for both process stabilization as well as long term thermal stability.

Advantages

• Low color provides an advantage over conventional systems
• Non-interacting with catalysts and mixed metal stabilizers compared to conventional systems.
• Excellent solubility in both polyether and polyester polyols providing long term photo-permanence.
