New polyurethane materials meet REACH standards
06 October 2017
Trelleborg Sealing Solutions' new polyurethane materials, Zurcon Z53 and Zurcon Z54, conform to the latest EU REACH environmental standards coming into force from November 2017. In addition, they meet customers’ requirements for higher operating temperatures.
REACH is a European Union regulation concerning the Registration, Evaluation, Authorisation & restriction of Chemicals. Zurcon Z53 and Zurcon Z54 have been developed over a long research and development cycle to meet the demanding requirements of the European Commission regarding substances prohibited unless an exemption applies or an authorization is granted.
Thomas Larsen, material development engineer at Trelleborg Sealing Solutions, says: “Trelleborg prides itself on being at the forefront in meeting forthcoming standards and legislation, often being on many of the boards and committees of standard setting authorities. Meeting REACH regulations is extremely important for polymer and elastomer seals. We especially respect the objective of the regulations to protect human health and the environment from chemicals; a philosophy that fits perfectly with Trelleborg’s objectives for our products to seal, damp and protect.”
Zurcon Z53 and Zurcon Z54 will supersede Zurcon Z51 and Zurcon Z52 as materials for slipper seals and scrapers used in demanding fluid power linear and rotary applications, including the tough conditions faced in mobile, construction and mining applications.
The materials have all the usual characteristics of Trelleborg’s Zurcon range of polyurethane materials, such as toughness and rigidity, as well as wear and scratch resistance and demonstrate the same performance characteristics of the materials they replace. In addition, the maximum operating temperature of Zurcon Z53 and Z54 has been raised by 20°C in water and water-based fluids – from 40 to +60°C.
