Welcome to my GrafCompounder Website

The intention of this website is to offer a PC-program, which allows to calculate recipes for rubber compounds using your own compound database. This can be done with any recipes either Rubber, TPE, Thermoplastic, Polyurethane or any other compounds as long as they normalized on polymer.

Working successfully with statistic experimental design in rubber compounding and processing I found it difficult to accept, that compounds stored away in databases could not be used neither in compound development nor for quick response to a customer request.

The handle such compound database a tool is needed other than a simple search tool. Some attempts were made in the past, to make such an unorganized, historically grown compound database an useful resource for compound development. For example, entering compound properties allow a formulation to be calculated. That would be much more helpful. GrafCompounder shows an easy and fast way, to analyze and finally to simulate a recipe from any compound database.

It is a common problem in all type of simulation. Without interpretation and analysis it produces nice data and graphs. With expert knowldege simulation becomes a "workbench".
We have started to work on the next version, hence this offer.

Next Exhibitions / Webinars / Seminars / Conferences:

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.
For information and special offers please visit: KnowHow Webinars

The GRTE Bangkok Thailand at Bangkok International Trade & Exhibition Center (BITEC). was postponed to 17th - 19th March 2021.
Hopefully Corona crisis has endedand we are back to (new) normal. We will make sure, this event will be one of the most important event in South-East Asia
