Non-halogen flame-retardant thermoplastic plastic flame retardant additive. Layered silicate (clay) filler that improves gas barrier properties.
BYK-MAX CT 4260 improves flame retardant properties by promoting dripping suppression and char formation, making it suitable for use in halogen-free flame-retardant thermoplastic compounds. BYK-MAX CT 4260 can reduce the amount of fillers such as aluminum hydroxide and magnesium hydroxide. This results in improved processing characteristics and physical properties, as well as a reduction in the weight of the compound. The barrier properties against oxygen, water vapor, and hydrocarbons can be enhanced by using BYK-MAX CT 4260. In bioplastics such as thermoplastic plastics and polylactic acid (PLA), the melt viscosity increases, allowing for improved dimensional stability during extrusion.

Applications/Examples of results
Recommended Uses - Aluminum hydroxide filled ethylene glycol-vinyl acetate (EVA) - Low-density polyethylene (LDPE/LLDPE) - Magnesium hydroxide filled polypropylene (PP) - Polypropylene (PP) film - Polylactic acid (PLA) film Recommended Addition Amount: 3-5% as an additive relative to the total formulation Addition Method To achieve optimal dispersion and separation of the additive, it is recommended to use a twin-screw extruder or BUSS kneader when compounding thermoplastic compounds. When compounding, it is beneficial to select a process unit with as long a length as possible (>40L/D) and a screw design with high dispersion performance. To avoid compression of the additive, please add it to the already melted polymer via a side feeder if possible.
