SABIC VALOX™ DR48 GY3113: The Ideal Glass-Fiber Reinforced Flame-Retardant PBT for Multiple Industries

The SABIC VALOX™ series of PBT resins holds a significant position in the global engineering plastics market due to its outstanding comprehensive performance. As a professional service provider in the trade of imported engineering plastic raw materials, we present a detailed interpretation of the SABIC VALOX™ DR48 GY3113 grade to help you precisely match material solutions and enhance product competitiveness.

Material Definition & Key Properties

VALOX™ DR48 is a 17% glass-fiber reinforced flame-retardant PBT injection-molding grade, with GY3113 being one of its gray color codes. Its core performance characteristics are reflected in three key areas:

1. Excellent Flame Retardancy – Achieves UL94 flame class V-0 (at 0.9mm thickness) and 5VA (at 3.0mm thickness), while also meeting the stringent Glow Wire Test (GWT) requirement of 960°C, providing outstanding self-extinguishing capability in the event of accidental overload or short circuit.

2. High Strength & Reliability – The 17% glass-fiber reinforcement provides a tensile strength at break of approx. 93 MPa and a flexural strength of approx. 140 MPa, with a flexural modulus as high as 5030 MPa and a Rockwell hardness of 118. It can withstand mechanical stress while ensuring precision and shape stability in complex environments.

3. Electrical Insulation – Features a volume resistivity as high as 4.0×10^16 ohm-cm and a dielectric constant of only 3.4, with stable performance under high voltage and high humidity conditions, making it the preferred insulating material for demanding electronic and electrical components.

Additionally, DR48 has a density of approx. 1.53 g/cm³, a very low water absorption rate of 0.07%, a heat deflection temperature (HDT) of 210°C (at 0.45 MPa), and a long-term service temperature range of 120°C to 140°C.

Typical Applications & Industries

• Electronics & Electrical – With its V-0/5VA flame rating and excellent insulation properties, DR48 is an ideal material for lamp holders, relay bases, coil bobbins, switch components, micro-switch housings, micro-motor casings, and various precision connectors.

• Automotive Industry – DR48 meets the demanding requirements of automotive components to withstand thermal stress and chemical corrosion within confined spaces. It is suitable for ignition system components, under-hood electronic parts, automotive lighting housings, and interior/exterior plastic trim. As new energy vehicles gain popularity, PBT automotive-grade reinforced flame-retardant materials are seeing strong demand and significant growth potential.

• Household Appliances – DR48 is commonly used in hair dryer fan blades, power tool insulation sleeves, lawn equipment, and garden tool components, as well as high-strength heat-resistant covers, significantly improving product lifespan and safety.

Conclusion

With its 17% glass-fiber reinforcement, excellent flame retardancy, high rigidity, and low moisture absorption, SABIC VALOX™ DR48 GY3113 has become a classic material choice across multiple industries. We look forward to leveraging our professional expertise and extensive experience to help you select the right material and enhance your product competitiveness.
