What is Polyurethane?

Polyurethane is an important group of products in the polymer family. Polyurethane was first synthesized in 1937 by the scientist
German Otto Bayer and was obtained by reacting diisocyanate with diol. Subsequently, diols were replaced by higher molecular weight polyols.

The polyurethane thus formed creates a more resistant and flexible structure. Three main raw materials play an important role in the production of polyurethane foam. These are; polyol, isocyanate, and water.

While part of the diisocyanate polymerizes with the polyol, a small part reacts with water to form a porous polyurethane structure. Catalyst, stabilizer, and other auxiliary agents are used to support the chemical reaction. Additionally; If desired, additives such as paints and flame retardants can also be added to the formulation to achieve specific properties.

At the end of the polymerization time (24-72 hours), a flexible and solid polymeric structure is formed. Two important measurements on the sponge are density (density) and hardness.

Quality is directly related to density. High density means high quality. Hardness has no effect on quality. Higher quality sponges may feel soft while lower quality sponges may feel hard.

All sponges lose hardness with use. Higher quality sponges lose their hardness more slowly. Color has no effect on the sponge in terms of quality and performance.

The natural color of the sponge is white. Color is only used to more easily distinguish sponges of different qualities.


Polyurethane Properties - Attributes

Polyurethane Density: Density, i.e., density, is defined as weight per unit volume and measured in kg/m3 or gr/dm3.

Flexible sponge is one of the most important properties of polyurethane and affects the durability and strength of the support. High-density products retain their original properties longer.

Polyurethane Hardness: The hardness of the flexible sponge in polyurethane is a measure of the surface touch or feel of the sponge.
Support is the sponge's ability to resist weight. Stiffness and support both affect sponge comfort. Sponge hardness or softness is not directly related to density. Many times, mistakenly, high-density sponges are thought to be harder. However, hardness is completely independent of density.

Hardness is measured by the force applied to compress a sponge sample to 40% of its original height.

Scope of Application

The polyurethane (PU) sector, which is one of the secondary branches of the plastics industry, began to be mentioned as one of the sectors of the future with the introduction of polyurethane into every aspect of life.
