Halogen-free flame-retardant portfolio expands

LUBRIZOL Engineered Polymers has developed several new halogen-free Estane ZHF thermoplastic polyurethane (TPU) grades that feature low toxicity, low smoke and low gas conductivity. The design versatility of Estane ZHF polymers expands the scope of applications in which the new grades can be applied, including thinner or coloured cables. The new ZHF resins also meet requirements for more sustainable alternatives because of their recyclability and improvement of processability in the extrusion of most cables. The new Estane ZHF TPU products include: • 90AT8 NAT 02 for robotic and communication cables • 58202 NAT 02, combining easy processability and low gas conductivity with flame-retardant performance • 58370 NAT 01, providing easy processability and low gas conductivity in compliance with IEC 62893 and EN 50620 standards for electric vehicle charging cables • 58211 NAT 0, with good thermal resistance and easy processability combined with flame-retardant performance • 85AT8 MATT, featuring a matt surface, good flame-retardant performance and easy processability Fabio Morelli, new business development senior manager for Lubrizol Engineered Polymers in EMEA, stated, “New emerging applications have demanding material requirements, and international cable-related regulations are also becoming more stringent. As an example, some Estane ZHF grades have been designed after a collaborative development process with key manufacturers of EV charging cables.”

have the standard features of a TPU (eg durability and good hydrolysis resistance), but also show very low conductivity levels. Lubrizol’s regulatory and legal expert team has ensured that the new Estane portfolio without halogenated flame retardants is compliant with the standards required by the cable industry.” With more than 60 years of experience and a worldwide network that includes formulation design, manufacturing and R&D, Lubrizol Engineered Polymers offers a broad portfolio of engineered polymers, including resins that are bio-based, recyclable, light stable, flame retardant, adhesive, chemically resistant, optically clear and fast cycling.
