ANTIOXIDANT 245 CAS NO.36443-68-2
ANTIOXIDANT 245 with CAS number 36443-68-2 is a partially hindered phenolic antioxidant supplied as a white powder by Guangzhou Chengshuai New Material Co., Ltd. Its molecular formula is C34H50O8 with a molecular weight of 586.8, and it exhibits a melting point range of 76 to 79 degrees Celsius. The product meets stringent purity standards with an assay of 98.0% minimum, ash content limited to 0.1% maximum, and volatility capped at 0.5% maximum. Transmittance values are 95% minimum at 425 nm and 97% minimum at 500 nm, ensuring optical clarity in applications.
This antioxidant is designed to provide excellent processing and long-term thermal stability, particularly in styrene polymers such as HIPS, MBS, and ABS, as well as engineering plastics like POM, PA, and polyurethane. It functions as an effective chain terminator in PVC polymerizations and can be introduced into monomers before polymerization for HIPS and PVC. The compound demonstrates synergistic effects when combined with benzotriazoles or HALS for enhanced thermal and light stabilization in outdoor applications.
Primary buyers include manufacturers in the plastics, rubber, and polymer industries seeking to extend the lifespan of their materials under thermal stress. The product is typically sourced in bulk for industrial applications, with logistics and trade terms negotiated directly with the supplier. Its versatility in stabilizing a range of polymers makes it a critical additive for producers aiming to improve the durability and performance of their end products.
