Diffutherm's corporate values ​​are central to our attitude and influence our business activities. Mutual trust, reliability, honesty and sincerity, both internally and externally, are the fundamental principles that are deeply rooted in the corporate culture of the Würth Group. Our commitment to these values ​​was first enshrined in the corporate philosophy written by Reinhold Würth in the 1970s.

These principles include not only compliance with all applicable rules and laws, but also the right attitude of employees, which is an integral part of the sustainable business 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 to complying with certain standards, guidelines and norms as part of our catalog of values.


Our Code of Conduct

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 upholding our corporate values. In order to make this transparent for our employees as well as for our customers, suppliers and other business partners, we have derived concrete rules of conduct based on our company values, which we have summarized again in the Code of Compliance of the Würth Group.

Open the Code of Compliance of the Würth Group below:

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. In addition, Würth Diffutherm guarantees that all information on particularly hazardous materials is provided in accordance with EU-REACH regulations.

The protection of our customers, partners, employees and our values are our top priority. That is why it is important to be aware of any compliance violations in good time.

Our Reporting Hotline SpeakUp

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

For example, the Reporting Hotline SpeakUp enables you to provide the Compliance Department with information about criminal activity 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 complete confidence.
