Polyester Polyols for Polyurethane Elastomers
Enviol Polytech Solutions provides high-performance polyester polyols and customized PU systems engineered for polyurethane elastomer applications. Our materials are designed to deliver superior tensile strength, abrasion resistance, load-bearing capacity and long-term durability across industrial environments.
Cast Polyurethane Elastomers (MDI Based)
Cast elastomers are typically formulated using polyester polyols reacted with MDI or prepolymer systems. Polyester chemistry enhances hardness, tear strength, and resistance to oils and solvents.
- Preferred Polyol: Polyester, medium to high molecular weight
- Key Properties: High tensile strength, abrasion resistance
- Applications: Rollers, wheels, industrial liners, seals
Thermoplastic Polyurethane (TPU)
TPU systems based on polyester polyols provide enhanced mechanical strength and wear resistance compared to polyether grades. They are widely used where high dynamic performance and surface durability are required.
- Polyol Type: Linear polyester
- Performance Focus: Abrasion resistance, load capacity
- Applications: Cables, footwear soles, films, hoses
Polyester vs Polyether in Elastomers
- Polyester Polyols: Higher mechanical strength, better oil and solvent resistance.
- Polyether Polyols: Improved hydrolysis resistance and low-temperature flexibility.
- Aromatic Systems (MDI): High strength and cost efficiency.
- Aliphatic Systems: UV-stable specialty elastomers.
