RECYCLOBYK® 4371

RECYCLOBYK® 4371 by BYK is a free-flowing stabilizer system for the recycling of polyolefins. It is a blend of antioxidants & co-stabilizers specifically developed to re-stabilize products. It enhances the processing and long-term stability of the recyclate. It preserves the melt flow properties and the long-term thermal stability. It helps to neutralize acids which may be present in the polymer from the previous processing and use. It can be dispersed into the polymer by using conventional extrusion compounding techniques. RECYCLOBYK® 4371 is used in polyolefin blends with different compositions, e.g. bottle fractions and polypropylene contaminated with other polymeric materials. It is suitable for PP exposed to aggressive substances, e.g. battery housings and mixed plastic from household or industrial waste streams. The recommended dosage level is 0.1-1%. It has a shelf life of 24 months.
