Explore our extensive portfolio of specialty antioxidants and additives from from SI Group that holds the solution for your TPO formulating challenges.
To meet today’s demanding applications, a broad class of roofing materials is now made from Thermoplastic Polyolefins (TPO). 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 is heat-weldable so seams are stronger and longer lasting. Unlike PVC roofing, TPO is eco-friendly, fully recyclable. TPO membranes are a cost effective choice while exhibiting a high resistance to puncture, impact, and tearing.
TPO membranes are not without their shortcomings. They have had significant challenges enduring the high heat and UV loads to which most roofs are exposed. This is why it's critical to incorporate a robust and proven stabilization package in your TPO formula.
Whether you are new to TPO or a seasoned veteran, the experts at ChemPoint and SI Group can help you with product suggestions to optimize your formula. Please see the table below to and give us a call to learn more.
| Product | Type | Description |
|---|---|---|
| ALKANOX™ Phosphite Antioxidants | Antioxidant | Organo-phosphite antioxidant that exhibits excellent hydrolytic stability. Effectively reduces peroxide induced oxidative degredation during processing including at high temperatures. |
| ANOX™ Binary Blend Antioxidants | Antioxidant | Solid binary synergistic blends used to protect polymers during high temperature processing and long term aging. Non-Dusting Blends are compact, often customized, cost-effective antioxidant blends. |
| ANOX™ Hindered Phenolic Antioxidants | Antioxidant | Provides very low volatility and excellent resistance to extraction from polymer compounds. Particularly effective against degredation during long-term aging, but can also be an effective process stabilizer and exhibits good resistance to discoloration. |
| LOWILITE™ Benzotriazole UV Absorbers | UV Stabilizer | Benzotriazole and Benzophenone UV Absorbers; ideal for UV resistance in a variety of polymer systems. |
| LOWILITE™ Hindered Amine Light Stabilizers | UV Stabilizer | Hindered Amine Light Stabilizers; Maximizes color yield in pigmented systems, improves resistance to acidic conditions, and does not migrate easily |
| LOWINOX™ Hindered Phenolic Specialty Antioxidants | Antioxidant | Antioxidants that provide low volatility and excellent resistance to extraction from polymer compounds, allowing exceptional processing and end-use stability. |
| LOWINOX™ S-Bridged Phenolic Specialty Antioxidants | Antioxidant | Sulfur containing secondary stabilizers that are non-discoloring and non-staining. |
| NAUGARD™ Metal Deactivators | Antioxidant | Unique antioxidant that includes metal deactivation. This product may be used where there is interference from metallic ions such as from residual polymer catalyst, inorganic pigments, or mineral filled polymers. |
| NAUGARD™ Thioester Specialty Antioxidants | Antioxidant | Auxiliary stabilizers used to promote long term ambient aging properties and allow for excellent color and processing. |
| ULTRANOX™ Solid Phosphite Antioxidants | Antioxidant | Features a higher phosphorus content than competitive phosphite antioxidants, offers high performance even at low loading levels for a more cost effective formula |
| WESTON™ Liquid Phosphite Ester Antioxidants | Antioxidant | Particularly useful as a secondary stabilizer in PVC |
| WESTON™ Solid Phosphite Antioxidants | Antioxidant | High-purity phosphite antioxidants that are effective heat, color, and viscosity stabilizers which provide additional synergies when paired with hindered phenols |
