BYK MAX HS 4334 is a long-term thermal stabilizer based on inorganic and organic stabilizers for use in reinforced polymers. BYK MAX HS 4334 consists of a combination of thermal stabilizers and carbon black. The stabilizers inhibit thermo-oxidative decomposition by intercepting radicals and decomposing reactive peroxides. BYK MAX HS 4334 also has a very positive influence on long-term heat aging, which makes it possible to comply with the automotive standard specifications more easily. Depending on the glass fiber content, adding approx. 2% of the additive can achieve a long-term heat aging duration of 1200 hours at 150 °C. BYK MAX HS 4334 provides benefits such as improved thermal stability and longevity for reinforced polymer composites used in the Advanced Materials industry.
