Antioxidant and UV Stabilizers for TPO Membranes

The SI Group is a global leader in manufacturing antioxidants, UV stabilizers, and compatibilizers that provide long-term protection for challenging applications. Thermoplastic Polyolefin (TPO) roof membranes are some of the fastest-growing commercial roofing applications. Furthermore, the SI Group's portfolio of solutions offers the building and construction industry innovation and protection for peak performance. 

A broad class of roofing materials is now made from Thermoplastic Polyolefins (TPO) to meet today's demanding building and construction applications. Unlike historically used EPDM membranes, TPO products are typically light in color and can reflect heat away from the building, decreasing cooling costs in the summer.

 

TPO roof membranes are heat-weldable, so seams are more potent and longer lasting. Unlike PVC roofing, TPO is eco-friendly and fully recyclable. TPO roof membranes are also cost-effective, exhibiting high resistance to puncture, impact, and tearing.


TPO membrane roofing applications are not without their shortcomings and significant challenges in enduring the high heat and UV loads to which most commercial roofs are exposed. Therefore, it is critical to incorporate a robust and proven stabilization package from the SI Group into your TPO formula.

The SI Group portfolio of antioxidant and UV stabilizer solutions below are used in various building and construction applications depending on your formulation needs and end-use.
