POM Kepital F20-03 NAT

What is POM F20-03 NAT?

Kepital® F20-03 NAT is a high-performance POM copolymer engineering plastic produced by Korea Engineering Plastics (KPAC). It stands out for its excellent dimensional stability, low moisture absorption, and superior impact resistance even at low temperatures.

With its well-balanced mechanical properties – strength, toughness, and low friction – Kepital® F20-03 Natural is widely used in automotive parts, gears, sliding bearings, electrical/electronic components, and precision engineering products.

Thanks to compliance with numerous international standards (Ford, GM, Chrysler, Valeo, etc.), this POM grade has become an ideal choice for manufacturers seeking durable, easy-to-process, and globally approved engineering plastics.

Advantages of F20-03 Natural Compared to Other POM Grades

1. Physical & Processing Properties

• Medium–high viscosity → easy injection molding, stable flow, minimal deformation.

• Mold shrinkage ~2.0% → tighter dimensional control compared to some standard POMs (1.5–2.5%).

• Low moisture absorption (0.20%) → superior to Nylon (PA) and many other POMs, ensuring dimensional stability in humid environments.

• RoHS compliant → environmentally friendly, export-ready.

2. Mechanical Properties

• Tensile strength 65 MPa & elongation at break 35% → combines rigidity and toughness, reducing brittleness and extending service life of moving parts.

• Flexural modulus 2550 MPa & flexural stress 87 MPa → strong load resistance, minimal warpage.

• Impact strength:

  • 6.5 kJ/m² at 23°C

  • 5.5 kJ/m² at -30°C → maintains toughness even at low temperatures, outperforming some brittle POM homopolymers.

3. Thermal Properties

• Heat deflection temperature (HDT) 100°C @1.8 MPa → suitable for general engineering applications.

• Melting point 165°C → typical for POM copolymers, stable for injection molding.

• Low coefficient of thermal expansion (1.2×10⁻⁴ cm/cm/°C) → excellent shape retention under temperature changes.

4. Electrical Properties

• Surface resistivity 10¹⁶ Ω, volume resistivity 10¹⁴ Ω·cm → excellent electrical insulation.

• Dielectric strength 19 kV/mm → outstanding performance in insulation applications.

• Flammability UL94 HB → basic flame resistance suitable for consumer and industrial use.

5. Key Advantages of Kepital® F20-03 Natural

• Balanced mechanical & chemical properties: stronger, tougher, and more ductile than many POM homopolymers.

• Easy processing: medium viscosity copolymer with good flow in complex molds.

• Dimensional stability & moisture resistance: absorbs less water than many POM grades.

• Low-temperature toughness: remains impact-resistant at -30°C, ideal for automotive and outdoor equipment.

• Automotive certifications (Chrysler, Ford, GM, Valeo, Delphi, etc.) → globally recognized in the automotive supply chain.
