PRODUCT FEATURES AND APPLICATIONS

● PEP-36 is a high-performance phosphite which provides marked process stability to polymers. It also has excellent resistance to hydrolysis and thermal stability. It is recommended for applications which require high-temperature processing and/or strongly avoid discoloring.

● PEP-36 protects polymers against thermal degradation, which drastically reduces discoloration and prevents the increase of melt flow rate of the polymer during high-temperature processing.
● PEP-36 shows a marked synergistic effect when used with phenolic antioxidants.
● PEP-36 approved as an indirect additive in food contact substances in US, EU and Japan. Potential application is food packaging. (For additional information such as kind of adaptable polymers, please ask our Sales Department.）

PEP-36 applications
• Polyolefins such as PP and HDPE
• Styrene resins such as PS and ABS
• Engineering plastics such as PA, PC, m-PPE, Polyesters
