Product Description
Revonox°U-5068L(U-5068L) Antioxidants
Description
Initial Color Stability: U-5068L significantly inhibits yellowing (Yellow Index) during TPU synthesis, even in high-temperature environments of 200°C to 250°C required for twin-screw polyurethane synthesis, greatly reducing yellowing caused by reactions with moisture and oxygen.
Revonox® U-5068 (U-5068) is a functional compound heat stabilizer developed by QiTi for polyurethane elastomer (TPU). Its main function is to effectively improve the initial color of the rubber particles in the thermal process of TPU, especially for heat-resistant (such as polyether), high processing temperature (harder specifications) and high viscosity specifications, it has quite good performance. In addition, for applications with oven aging or heat aging requirements, U-5068 can help improve heat yellowing resistance and have a certain effect on maintaining physical properties.
Recommended Applications
U-5068 is commonly used in polyether, polyester or other modified TPU systems. The recommended addition amount is 0.2-0.5% at the synthesis end; for applications with oven aging or heat aging requirements after rubber particle synthesis, the recommended addition amount is 0.5-1.0%.
