BYK-Chemie GmbH

BYK is making intensive preparations for the upcoming K 2019 trade show, which will take place from October 16 to-23 in Düsseldorf’s exhibition halls. At Booth E17 in Hall 5 the main focus will be on the new additive BYK-MAX CT 4260, which is an organophilic sheet silicate for use in thermoplastics such as polyamides.

BYK-MAX CT 4260 is the first innovative product from the new group of thermoplastic additives launched on the market under the trade name “BYK-MAX”.

It is especially suitable for use with halogen-free flame retardant thermoplastic compounds, since incorporating the additive improves not only the flame retardant properties but also the dropping behavior and crust formation. In return this new, highly specialized additive also enables the filler content, e.g. aluminum or magnesium hydroxide, to be reduced. This leads to a significant improvement in the process and physical properties and to a reduction in the overall weight.

As well as improving the flame retardant properties, the use of BYK-MAX CT 4260 can enhance barrier properties to oxygen, water vapor, and hydrocarbon.

In thermoplastics, such as polyamides (PAs), and bioplastics, such as polylactides (PLAs), the melt viscosity is also increased, enabling, for example, an improvement in dimensional stability during profile extrusion to be achieved.

In addition, other new, customized BYK additives – that fully utilize the potential of modern plastics and optimize their manufacture – for all kinds of different fields of application will be presented to the trade professionals at K 2019.

Natural leather and coated fabrics are used in many consumer products. These range from car seats to furniture and include shoes, bags, clothing, and accessories. Our additives support the production and finishing of natural leather and coated fabrics based on PVC or polyurethane (PU). Depending on the applications, our customers can choose between solvent- and water-based additives. Our surface additives help optimize the quality and feel of the materials. Our wax additives create shine, smoothness, grip, and comfort. Our wetting and dispersing additives serve to incorporate pigments and fillers into the finishing.
To optimize different processing parameters during the production of the finishing, our defoamers, rheology and processing additives are first choice. Defoamers destroy unwanted foam bubbles, generating flawless surfaces. Rheology products better the flow behavior, and processing additives improve the release properties as well as the cell structures of the PVC plastisols.

With our wetting and dispersing additives, viscosity reducers, and foam stabilizers, we meet a number of challenges arising during the production of roll materials as well as carpet and luxury vinyl tiles (LVT). The wetting and dispersing additive BYK-1165, for example, is designed to incorporate fillers into highly filled plastisols with low to medium shear rates. DISPERPLAST, on the other hand, facilitates the incorporation of fillers into thermoplastic PVC compounds. Both products also optimize the flow behavior of the materials. For anti-static applications, we recommend BYK-5128.

By reducing viscosity, our VISCOBYK additives support the plastisol’s processability. In particular, this applies to materials with few or no fillers. For indoor applications, VISCOBYK-5120 und VISCOBYK-5125 have proven extremely successful, as they show few emissions thanks to their low volatility.

BYK-8020 and BYK-8070 help to stabilize mechanical foams, one is based on silicone, the other on soap.

Engineering plastics based on polyamides need to show a number of properties, including heat resistance, when used as structural components in the electrical and the automotive industry. In polyamides and polypropylenes, the highest thermal demands can be achieved using our BYK-MAX HS additives. BYK-MAX HS 4312 provides exceptional resistance to automotive fluids.
