• Tensile Strength: Increases by up to 50–100% compared to unfilled ABS, allowing the material to withstand higher loads before failure.
• Stiffness (Flexural Modulus): Dramatically improved rigidity makes ABS 30 GF ideal for structural components that must resist deformation under stress.
• Impact Resistance: While pure glass fibers can reduce ductility, the optimized dispersion in ABS 30 GF maintains good impact toughness, especially at room temperature.
• Cree Resistance: Reduced long-term deformation under sustained load, making it suitable for load-bearing applications.

These enhancements make ABS 30 GF a preferred choice for engineering-grade parts in automotive, industrial equipment, and consumer electronics where durability and dimensional stability are critical.

One of the most significant advantages of ABS 30 GF over standard ABS is its enhanced thermal performance, primarily due to the glass fiber reinforcement:

• Heat Deflection Temperature (HDT): ABS 30 GF typically exhibits an HDT of around 100–110°C at 1.8 MPa, which is approximately 25–35°C higher than unfilled ABS. This allows it to retain structural integrity in hotter environments.
• Thermal Expansion: The glass fibers reduce the coefficient of thermal expansion, improving dimensional stability during temperature fluctuations.
• Long-Term Heat Resistance: Maintains mechanical properties better than standard ABS when exposed to continuous heat, such as under-hood automotive components or near heat-generating electronics.

Common high-temperature applications include engine covers, electrical connectors, HVAC housings, and power tool casings—environments where standard ABS would soften or warp.

ABS 30 GF is an excellent electrical insulator, despite the inclusion of glass fibers. Here’s why this matters:

• Volume Resistivity: Typically exceeds 10¹⁵ Ω·cm, indicating very low electrical conductivity.
• Dielectric Strength: High resistance to electrical breakdown, making it safe for use in live electrical environments.
• Dielectric Constant: Ranges between 3.0–4.0, which is favorable for signal integrity in electronic enclosures.

Because glass fibers themselves are non-conductive and evenly dispersed within the insulating ABS matrix, the composite does not form conductive pathways. This ensures that ABS 30 GF remains safe and effective for applications such as:

• Electrical junction boxes
• Switchgear housings
• Connectors and sockets
• Consumer electronic enclosures (e.g., printers, routers)

However, it should not be used in environments requiring EMI/RFI shielding unless coated or blended with conductive additives.
