Polyester Polyols for elastomers

In the production of elastomers, a carefully selected blend of polyester polyols is used to achieve the desired mechanical properties. Our developed formulations and expertise enable us to produce materials that fully meet customer expectations.

Key characteristics of elastomers include: strength, flexibility, elongation, recovery to original shape, and abrasion resistance. These properties are influenced by the acids and alcohols used in the polyester polyol production reactions.

Modern, durable, and safe elastic materials with a broad range of properties have found applications in many industrial fields.

High strength

Excellent flexibility

Short polymerization time

Wide range of applications

Low curing temperature

Polyester polyols for cast elastomers

Premium-grade polyester polyols are used in the production of cast elastomers. This group of products is specifically designed for this application. The selection of appropriate polyols and their ratios are crucial for achieving specialized properties in the final elastomer products.

Polyester Polyols for cast elastomers
Hydroxyl number 54-60 [mgKOH/g]
Acid number Max 0,6 [mgKOH/g]
Viscosity at 75°C Max 700[mPas]
Water content, no more than 0,03%

Cast elastomers achieve their final shape in molds where polymerization occurs. The components produced this way are used in various industries, so the formulation and production technology must ensure the consistency of properties offered by the final products.

Thanks to high-quality polyester polyols, these products exhibit the appropriate elasticity, mechanical strength, chemical resistance, and low wear. Cast elastomers can successfully replace rubber components, offering several times greater durability. They are used in applications where mechanical properties and strength are crucial, such as solid wheels, shock absorber components, screens for separators, and other operational elements.

Polyester Polyols for footwear outsolers

Footwear outsolers are now highly advanced products, so their production requires various carefully selected formulations. Due to the diverse properties of outsolers, different polymer blends are used for their molding.

Microporous elastomers—referred to in the chemical industry—are elastic materials with carefully selected elongation properties, capable of quickly returning to their original shape. Abrasion resistance, which ensures the durability of the finished footwear, is also crucial. Compared to cast elastomers, microporous materials contain less water in their composition.

Product Technologist

Our portfolio includes polyesters designed for both solid (cast) elastomers and micro-porous elastomers (for footwear soles). Some of the polyesters have deliberately modified reactivity, which shifts the processing window and facilitates production.
