The Diffutherm corporate values are the focus of our attitude and influence our business activities. Mutual trust, reliability, honesty and straightforwardness, both inwards and outwards, are the fundamental principles deeply ingrained in the Würth Group's corporate culture. Our commitment to these values was first laid down in the Corporate Philosophy which was written by Reinhold Würth in the 1970s.

These principles do not just include adhering to all applicable rules and laws, but also the proper mindset of the employees which constitutes an integral part of the sustained corporate success of the Würth Group.

We therefore expect our managers, employees and business partners to comply with national and international laws and regulations. In addition, we have committed ourselves to comply with certain standards, guidelines and norms as part of our catalog of values.

Our Conduct Guidelines

Code of Compliance of the Würth Group

We attach great importance to strict compliance with all applicable national and international rules and laws as well as to the preservation of our corporate values. In order to make this transparent to our employees as well as to our customers, suppliers and other business partners, we have derived concrete rules of conduct based on our corporate values, which we have summarized once again in the Code of Compliance of the Würth Group .

It is equally important to us to provide our customers with a value chain that is free from dubious backgrounds. For example, the use of conflict minerals is not an option for us. Furthermore Würth Diffutherm warrants providing any information about especially hazardous materials in accordance to EU-REACH regulations.

Our Reporting Hotline SpeakUp

Since we are looking for open communication with our customers, suppliers and employees, the so-called Reporting Hotline SpeakUp exists within the Würth Group. Investigations show that often information from third parties leads to the clarification of white-collar crime.

Thus, the Reporting Hotline SpeakUp enables you to give the Compliance Department information on criminal activities or serious violations of laws, our Code of Compliance or other guidelines. If you notice a violation, you can report it, even anonymously, and in any case in absolute confidence.
