Cold heading oil launched

Concerns about PAHs and BaP (polycyclic aromatic hydrocarbons and benzo[a]pyrene) have been present in the metalworking industry since 2015. Some petroleum-based products, such as process lubricants, can release PAHs and BaP under severe operating conditions. For greater vigilance, the French Health Insurance authority issued a recommendation, reference R.451, concerning the “Prevention of chemical risks caused by cutting fluids”. It uses the data provided by the INRS on the risks and thresholds related to BaP contained in new and in-service neat cutting oils. While this issue is regularly raised when using machining neat oils, there are no recommendations for cold heading operations. Guided by its HSE (health, safety and the environment) and CSR (corporate social responsibility) principles, Condat decided to go further by taking into account this question and by anticipating the regulation. The company’s in-depth knowledge of how to reduce PAHs/BaP in in-service machining oils led to the development of Neat Green oils, which do not show an increase in BaP content after 1,500 hours of machining. In early 2018, Condat requested its R&D laboratory to work on new formulas for cold heading oils with neutral impact in terms of BaP. Beyond its CSR commitment, the company also wants to address the concerns of automotive suppliers and provide customers with the safest possible products. The objective was to co-develop with major automotive groups a high-performance product for very difficult forming operations. After six months of research, Extrugliss HT 268 VP was created. In partnership with an automotive supplier, the product was tested for nearly 12 months on cold heading operations for the manufacture of seat pinions and hubs, and reportedly showed good results. Available for sale since June 2019, Extrugliss HT 268 VP is positioned as a premium product specially formulated for extreme operations that generate excessive heat (stainless steel, alloy steel with high elastic limit, etc).

Developed to solve BaP emissions problems, the neat cold heading oil is formulated from high-quality, highly refined base oils, and contains fewer residual compounds that may degrade to PAHs. It resists oxidation, increases the life of the baths and facilitates degreasing by preventing the formation of sticky residues on the parts. It is less volatile, and limits oil evaporation and mist generation, improving the atmosphere in workshops. The dual-purpose cold heading oil provides lubrication characteristics to the mechanical components of cold heading machinery as well as lubrication for the deformation operations, and has a viscosity of 68 cst.
