ENRI in Action: Your Polyurethane Expert for Modern Industry
Introduction
At ENRI, we bring over 35 years of experience in the implementation of polyurethane materials. This essential component of modern industry allows us to develop with you the ideal elastomer for your most demanding industrial projects.
Polyurethane (PU) is now regarded as one of the most versatile and high-performance polymers on the market. In this article, we’ll give you a comprehensive overview of this exceptional material, illustrated by our recent projects and technical expertise.
What is Polyurethane?
Polyurethane is a polymer obtained through the reaction between a diisocyanate and a polyol compound. Depending on the formulation, it can take several forms: rigid foams, flexible foams, elastomers, coatings, adhesives, and more.
ℹ️ Info: The first polyurethane foams date back to the 1950s, but recent technological advances have taken it even further – notably with the development of “smart PU foams” designed for highly specific uses.
The Manufacturing Process
| Step | Description | Our Expertise |
|---|---|---|
| 1. Mixing | Combination of diisocyanates and polyols | Precise tuning of mechanical properties |
| 2. Pre-polymer | Beginning of exothermic reaction | Optimal control of material density |
| 3. Molding | Shaping (gravity casting, injection, bonding) | Custom fabrication of technical parts |
| 4. Finishing | Drying, cutting, or assembly | High-performance coatings |
Why Choose Polyurethane?
Polyurethane is at the core of our solutions due to its many technical benefits:
• Excellent resistance to wear, impact, and tearing
• Superior thermal and acoustic insulation
• Great vibration absorption and low deformation
• Excellent adhesion to metal surfaces
• Chemical resistance to harsh environments (oils, humidity, aggressive products)
• Wide range of hardness levels and finishes
• Flexible formulations (rigid, semi-rigid, elastomeric)
• Option for eco-friendly formulations (bio-based PU)
💡 Tip: If you’re looking for a material suitable for extreme conditions (humidity, heat, corrosion), polyurethane often stands out for its longevity and efficiency.
