Title: Geza Avar: Innovator in Polyurethane Technology

Introduction

Geza Avar is a notable inventor based in Leverkusen, Germany. He has made significant contributions to the field of polyurethane technology, holding a total of 11 patents. His work focuses on innovative methods for producing various types of polyurethane foams.

Latest Patents

One of his latest patents is a method for producing soft to medium-hard structural polyurethane foams. This invention provides a process for preparing flexible to semi-rigid polyurethane molded items with compacted edge zones that have a specific hardness, along with a much more flexible cellular core, known as integral foams. The process utilizes physical blowing agents from a set comprising hydrocarbons. Another significant patent involves stable dispersions of polyhydrazodicarbonamides. This invention relates to a process for preparing stable dispersions of hydroxyl-containing polyhydrazodicarbonamides in a hydroxyl-containing compound. The dispersions are created through the reaction of organic isocyanates, isocyanate-reactive compounds with a molecular weight ranging from 400 to 10,000, relatively low molecular weight isocyanate-reactive compounds, and hydrazines or hydrazides. This invention also covers the dispersions prepared by this process and their use in creating polyurethane foams with exceptional hardness.
