The New BYK-MAX Series: High Performance Plastics Additives for Compounders and Converters

To the extent that our everyday life has become unimaginable without plastics, additives play an increasingly important role for materials. They ensure quality and functionality.

Our BYK-MAX additives improve processing of plastics by maximizing efficiency during production and improving throughput. This new product group includes processing aids for PE, PP, PET, and Polyamides, but also for thermoplastic compounds based on PE and PP, and for masterbatches. Our functional BYK-MAX additives optimize material properties and add value to thermoplastics. They range from anti-fog to anti-scratch and include flame retardancy, UV stability, nucleation and desiccation as well as solutions designed to improve the the heat stability of nylon-based polymers used in electric and electronic products.


The start is made by two additives based on clay technology:


Phyllosilicate for use as a flame retardant synergist for halogen-free flame retardant thermoplastics as well as to improve the physical and barrier properties in thermoplastic compounds.

BYK-MAX CT 4260 is particularly suitable for halogen-free flame retardant thermoplastic compounds, as its addition improves the flame retardant properties as well as the dropping behavior and crust formation. It can reduce the filler content of, for example, aluminum or magnesium hydroxide.
This improves process and physical properties, and reduces the overall weight. The barrier properties to oxygen, water vapor and hydrocarbons can be increased by using BYK-MAX CT 4260. In thermoplastics, such as polyamides (PA), and bioplastics such as polylactides (PLA), the melt viscosity is increased, enabling an improvement in the dimensional stability during profile extrusion.


Additive based on an organo-modified phyllosilicate to provide ultra-efficient reinforcement to thermoplastic compounds.

BYK-MAX CT 4270, when added to a TPO or polyolefin composite, allows for a lower total mineral content, lower final density, and an improvement of the surface appearance, the mold flow, the dimensional stability and the scratch resistance. The high reinforcement significantly increases physical properties such as tensile strength, for example in TPO-based automotive parts or traditional mineral- or glass-filled composites.
