Products Description
TH-CPL is a high-molecular-weight, low-volatile polymer-based hindered phenol. It provides efficient thermal and oxidative stability protection while also having the characteristics of no color change, no pollution, and extreme resistance to extraction. Its low volatility enables it to maintain its activity throughout high-temperature processing and long-term use.
Its high molecular weight structure gives it excellent anti-migration ability, and it is not prone to leaching from the product even after multiple washes or boiling water cooking, making it particularly suitable for latex products (such as gloves, baby bottles) and rubber elastomers that need to be reused.

FAQ
Q: Why is TH-CPL suitable for latex systems?
A: It has good water dispersibility, excellent extraction resistance and low volatility. It will not interfere with latex vulcanization and hardly blooms, which makes it a preferred antioxidant for latex products.
Q: Could TH-CPL be used in white or light-colored rubber and plastics?
A: Yes. It is a non-discoloring and non-staining antioxidant, unlikely to cause yellowing or staining, ideal for light-colored formulations.
Q: What advantages does TH-CPL have over small-molecule antioxidant BHT?
A: It has a high-molecular structure with ultra-low volatility, good migration and extraction resistance, better long-term aging stability and low blooming risk.
Q: How to store Antioxidant TH-CPL?
A: Keep tightly sealed in a cool, dry and ventilated warehouse, protect from light and moisture. Keep away from heat sources and strong oxidants. Standard package: 20kg/bag. Prevent caking caused by moisture and avoid long-term exposure to air.
