Lubrizol ISOPLAST® Engineering Thermoplastic Polyurethane (ETPU)
ISOPLAST® is Lubrizol’s engineering-grade thermoplastic polyurethane (ETPU), combining the high strength and dimensional stability of amorphous resins with the chemical resistance and processability of semi-crystalline resins.
Product Types
-
Impact-resistant grades
-
High-transparency grades
-
Glass fiber reinforced grades
Glass fiber–filled grades are known for excellent transparency and high heat resistance, and are widely used in pneumatic tool components and truck oil filter bowls for globally recognized brands.
Key Advantages
-
Impact-resistant grades provide exceptionally high real-world hardness, ideal for parts exposed to frequent and severe impact.
-
Transparent grades support injection molding, extrusion, and blow molding, balancing aesthetics and mechanical performance.
-
Glass fiber reinforced grades maintain good flow and processing efficiency even at up to 60% fiber loading, offering a high-strength, cost-effective engineering plastic solution.
Processing Recommendations
-
Reduce shear and excessive heat
-
Use low back pressure
-
Use low injection speed
-
Shot size ≥ 25% of barrel capacity
-
Recommended compression ratio: 2.0:1–2.5:1
-
For long glass fiber grades, use a reverse barrel temperature profile
202LGF-40% / 202LGF-60%
-
Features: Heat-resistant base resin with long glass fiber (40% / 60%), delivering high temperature and high strength performance
-
Applications: Truck oil filter bowls, automotive parts, high-temperature load-bearing brackets, heavy equipment structural components
