Welcome to my GrafCompounder Website

This website is all about a PC-program "GrafCompounder 4.0", which allows to calculate recipes of polymer compounds using a compound database. This can be done with Rubber, TPE, Thermoplastic, Polyurethane or any other compounds as long as the formulas are 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 be used neither in further compound development / optimization nor for a quick response to a customer request for price calculation for example.

To handle a compound database, a tool is needed other than a simple search tool. In the past several attempts were made to use an unorganized, historically grown compound database as an useful resource for compound development, but failed. GrafCompounder opens the possibility of a database query - specifically a multi target query - by calculation of a compound formulation according to all targets, which can either be ingredient or property values. The result of this calculation is a formulation that either fulfills all specifications or provides the best compromise. Unlike AI (Artificial Intelligence) programs, the data used for the calculation can be traced back, which allows to eliminate errors in the database. GrafCompounder shows an easy and fast way to analyze a formula database and finally to simulate a recipe from any compound database.

Please visit my personal website: Hans-Joachim-Graf, to learn about my activities like Consultancy, Training and Education in Rubber Compound Development, Processing and the usage of Statistic Experimental Design (DoE) in the rubber manufacturing environment.


SIMULATION OF RUBBER COMPOUND FORMULA? You think, that is impossible?


RELIABLE DATA, EXPERIENCE AND SOFTWARE is needed to successfully simulate a compound formula with its properties.
It is a common problem in all type of simulation: Without interpretation and analysis, only nice data and graphs are produced. With expert knowledge simulation becomes the developers "workbench".
The Grafcompounder 4.0 has been released June 2021.
