RECYCLOBYK® 4373

RECYCLOBYK® 4373 by BYK is a free flowing, stabilizer system with repair properties for recycling plastics. It is a blend of antioxidants, co-stabilizers and reactive additives. It has been specifically developed to re-stabilize. The product enhances the processing of the recyclate. It is a ready-to-add additive package, which the compounder/recycler can use without further premixing. It improves mechanical and long-term thermal properties combined with preserved rheological properties add value and enhance the application possibilities of the recyclate. RECYCLOBYK® 4373 helps to stabilize plastic recylates, providing protection against the negative effects of impurities such as paint or ink residues during processing and heat aging. It is especially recommended for polyolefin blends, PP/EPDM contaminated with paint residues, e.g. TPO scrap, PC/polyester blends contaminated with paint residues, e.g. PC/PBT scrap, post-industrial and post-consumer polymers like PO-mixtures with polyamide or polyester impurities. It is recommended for engineering thermoplastics. The recommended level is 0.1%-2%, depending on the residual stabilizer content and the amount of other polymer impurities in the recyclate. The shelf life of this product is 24 months.
