There's no contradiction: white yet conductive plastic

The new Original Material "S" plus+® white ESD family member is therefore the ideal material for clean room technology and perfect for use in laboratory environments. For example, if it is used as a work surface, ESD-sensitive products (ESDs) can be processed without any problems. The modified UHMW-PE also reliably meets the electrical engineering requirements, which require a slow discharge speed for sensitive electronic components. It is approved for ESD protection zones in accordance with the Environmental Protection Agency (EPA) and complies with the standards 61340-5-1 and DIN EN 61340-5-1.
Medical engineering in turn benefits from the fact that no black abrasion occurs as with standard materials and static charging is avoided at the same time when using this plastic. This argument is also a big plus for the food industry, which is also subject to strict hygiene requirements. Original Material "S" plus+® white ESD can be used in the food processing industry as it is certified as food-compliant in accordance with the European Union (EU) and the Food and Drug Administration (FDA).

Equipped with a molecular weight of 5x 106 g/mol and a density of ≤ 0.94 kg/dm³, it is characterised by the technical properties of the tried-and-tested "S" plus+® family. The very good wear and abrasion resistance and excellent chemical resistance are obvious. In addition, Murtfeldt has succeeded in creating a new product with Original Material "S"plus+® white ESD: the white plastic is the first material produced by Murtfeldt to have a surface resistance that fluctuates between a lower limit of 106 Ω and an upper limit of 109 Ω. Following intensive research, Murtfeldt has found an answer to the frequent demands from customers and is pleased to be able to offer a further solution entirely for the benefit of the customer.
