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 training designed to your specific needs, which enables you to make the utmost profit of my knowledge.

My area of expertise is:

  • Rubber formulation developemnt using Statistic Experimental Design [DoE] Technique
  • Process improvement in mixing, extrusion and injection molding

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

The software "GrafCompounder" was developed, to be able to utilize any compound database in search for a solution., It is based on algorithm used in Artificial Intelligence [AI] Software. Data containing compound recipes and their properties allow a formulation to be calculated according to targets. You will find more information under my separate website GrafCompounder together with literature and a price list.

Next Conferences / Webinars / Seminars:

Due to the necessary precautions to be followed because of the Covid-19 outbreak, we do not provide seminars, conferences or exhibtions this year.
Instead we offer webinars held by TechnoBiz consultants.

The GRTE Bangkok is postponed to March 2022.
It is our believe, that such an event will not be possible until most population is vaccinated to guarantee the safety of visitors, participants and staff We will make sure again, this event will be one of the most important event in South-East Asia
for the rubber business with seminars, company presentations, a research showcase and more.
