BYK-MAX HS 4334

BYK-MAX HS 4334 by BYK is a VOC- & dust-free, easy to handle, granulated long-term thermal stabilizer based on inorganic and organic stabilizers for use in PP-GF. It consists of a non-adhesive granulate and a combination of thermal stabilizers and carbon black. The stabilizers inhibit thermo-oxidative decomposition by intercepting radicals and decomposing reactive peroxides. It also has a very positive influence on long-term heat aging (LTHA), 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. It is suitable for processing at temperatures up to 300°C. BYK-MAX HS 4334 is added via volumetric or gravimetric dosing units during processing in all extruders and injection molding machines. It is suitable for long fiber-reinforced pellets for automotive parts, underbody paneling, screens and structural components. The recommended level is 2% additive (as supplied) based on the total formulation for 20-30% glass fiber content and 2.6% additive (as supplied) based on the total formulation for 40% glass fiber content. The shelf life of this product is 12 months.
