Polyurethane (PU) elastomers have established themselves as high-performance solutions in strategic sectors such as automotive, mining, and industry in general, and Amino has taken part in this. Recognized for their versatility, mechanical resistance, and customization capability, they efficiently replace conventional materials, delivering greater durability, better performance, lower maintenance cost, and a reduced environmental impact.
At Amino Química, we believe that they are protagonists in the technological evolution of several segments and therefore we inaugurated our Elastomers Line with total focus on this market.
Where do elastomers make a difference?
Polyurethane elastomers present excellent performance in parts that require abrasion resistance, flexibility, and dimensional stability, even under severe conditions. Some practical applications include:
Industrial wheels and casters: longer service life compared with conventional rubbers;
Scrapers, vibrating screens, hydrocyclones, and pipe coatings: with high resistance to impact, abrasion, and chemical agents, extending equipment durability and the efficiency of mining processes.
Automotive components: bushings, mounts, and parts that combine flexibility with robustness.
PIGS: Used for inspection and removal of residues in oil and gas transport lines, ensuring operational efficiency and safety.
With a hardness range that varies from 50 Shore A (flexible) up to 83 Shore D (rigid), PU elastomers can meet from high-flexibility applications to extreme requirements of mechanical resistance.
Differentials of PU elastomers
What makes polyurethane elastomers so valued is the sum of benefits compared to plastics and rubbers:
Superior durability and extended service life;
Excellent abrasion resistance, an essential factor in mining and transport;
Adjustable flexibility, without loss of performance;
Proven cost-benefit, with reductions of up to 50% in maintenance costs;
Total customization in hardness, colors, chemical resistance, and shape.
These attributes make elastomers the right choice for those who seek performance combined with operational efficiency.
Trends and sustainable innovation
The elastomers segment has been going through a transformation marked by innovation and sustainability. The main trends include:
MOCA-free formulations, which reduce risks to occupational health;
Low Free systems, with lower content of free isocyanates, expanding safety;
New chemical combinations (TDI, MDI, PPG polyols, PTMEG and esters), adjusting properties such as chemical resistance, elasticity, and low abrasion loss;
Automation and process control, ensuring standardization and lower generation of residues;
Greater durability of parts, reducing the frequency of replacements and disposal into the environment.
Thus, besides delivering technical performance, polyurethane elastomers contribute to a smaller ecological footprint, aligning themselves with global demands and Amino’s values for more sustainable solutions.
