Welcome to my Website


The intention of my website is to share my personal experience with everybody, who is involved in rubber, thermoplastic elastomers, polyurethan and their processing.

Continuing education is a key to success. With in-house seminars or workshops I offer you training designed to your specific needs, which enables you to make the utmost profit of my knowledge.

With my personal experience gained in my business life, I am interested in disseminate my knowledge through seminars or workshops in rubber technology and statisic experimental design (DOE). You will find detailed information under "training."

The software "GrafCompounder" was developed, to profit from your own compound database. You will find more information under my separate website GrafCompounder together with literature and a price list.
