Lubrizol: Expansion of HFFR TPU portfolio

Lubrizol has recently introduced halogen-free Estane ZHF TPU grades mainly for cable production that are said to feature low toxicity, low smoke and low gas conductivity. The company said that the design versatility of the new products polymers expands the scope of applications, including thinner or coloured cables.

    Estane ZHF 90AT8 NAT 02. Ideal for robotic and communication cables.

  • Estane ZHF 58202 NAT 02. Easy processability and low gas conductivity combined with very good flame-retardant performance.
  • Estane ZHF 58370 NAT 01. Easy processability and extremely low gas conductivity in compliance with IEC 62893 and EN 50620 Standards for electric vehicles’ (EV) charging cables.
  • Estane ZHF 58211 NAT 01. Very good thermal resistance and easy processability with very good flame-retardant performance.
  • Estane ZHF 85AT8 Matt surface jointly with good flame-retardant performance and easy processability.

Fabio Morelli, New Business Development Senior Manager for Lubrizol Engineered Polymers in EMEA, announced that: “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.”

He adds that the ZHF 58202 and 58370 grades have the standard features of a TPU (e.g. durability and good hydrolysis resistance), but also show very low conductivity levels. Lubrizol’s regulatory and legal expert team has ensured that the new TPU portfolio without halogenated flame retardants is compliant with the standards required by the cable industry.”
