Antioxidant Solutions for Polyurethanes (PUR) & Polyols
SI Group's comprehensive portfolio of primary and secondary antioxidants for Polyurethanes (PUR) and Polyols provide excellent protection from oxidation, discoloration, degradation, and scorch.
THE POLYURETHANE MARKET
Polyurethanes (PUR) are one of the most adaptable polymers available today and can be utilized in various applications and end-markets. Polyurethanes (PUR) not only contribute towards consumer safety and comfort, but they can also potentially reduce energy output costs.
SI GROUP STABILIZERS
The SI Group's portfolio of antioxidants and stabilizer additives provide excellent performance protection against ongoing thermal exposure and ultraviolet light which can inevitably degrade the Polyurethane over its lifetime. This stabilizer portfolio for Polyurethanes (PUR) and Polyol industry includes:
- Antioxidants that are Phenolic and Amine-based
- Outstanding execution in reduced emission solutions
- Liquid phosphites with Zero-Phenol
- Stabilizers for UV Light exposure
- Completely BHT-Free
WHAT IS SCORCH? AND HOW DO YOU PREVENT SCORCH?
Through the polymerization process, scorch from exothermic reactions can potentially cause discoloration and physical damage to the center of the polyurethane foams.
- Temperatures of 160°C and more cause exothermic reactions in polyurethane foam systems
- Extreme instances may lead to self-ignition of the polyurethane foam
Polyurethane foam scorch can be controlled by the addition of SI Group's antioxidant additives.
