Polycarbonate Glass-Filled Granules Properties, Uses, and Applications

1. Polycarbonate Glass-filled Granules: Properties, UsesAnd Applications

2. What Are Glass-Filled Granules? Glass-filled granules are produced by adding glass fibers to a base polymer resin, typically engineering thermoplastics such as polycarbonate. The glass fibers are usually in the form of short fibers or glass beads that are evenly distributed throughout the polymer matrix. This combination of polymer and glass fibers creates a composite material with superior mechanical properties compared to the base polymer alone. Popular commercial options include PC FR V0, 943A, and 945, widely used in automotive and electrical applications for their flame-retardant and mechanical properties.

3. Types of Glass-Filled Granules Glass-filled granules can be categorized based on the type and volume of reinforcement added: Short Glass Fiber-Reinforced GranulesImprove rigidity and tensile strength while maintaining ease of processing. Grades like PC 10% GF FR, PC 20% GF FR, and PC 30% GF FR are excellent examples. Long Glass Fiber-Reinforced GranulesThese provide superior impact resistance and are often chosen for structural applications requiring high durability. Glass Bead-Reinforced GranulesPreferred for applications that demand better surface finish and reduced warpage. Glass-Filled Granules with Different Polymer ResinsPolycarbonate-based formulations such as 945U, 945AU, and PC FR GRANULE deliver excellent flame retardancy along with enhanced strength.

4. Key Properties of Glass-Filled Granules Adding glass fibers to polymers enhances several critical characteristics: Increased Strength and RigidityEspecially in grades like PC 30% GF FR and PC 20% GF FR, which are used in load-bearing components. Improved Dimensional StabilityEnsures minimal deformation under thermal or mechanical stress. Grades like 940A and 945AU are commonly used in precision parts. Enhanced Thermal StabilityFlame-retardant grades like PC FR V0 and 943A are ideal for high-heat environments, particularly in electrical housings and connectors. Better Wear and Abrasion ResistanceShort glass fiber grades such as PC 10% GF FR offer good performance in moving parts or friction-heavy applications.

5. Reduced Creep and FatigueAllows prolonged mechanical use without material degradation. Examples include 945 and 945U. Low Thermal ExpansionThis makes materials like PC 30% GF FR suitable for high-precision applications. Improved Electrical PropertiesGrades like PC FR GRANULE and 940A offer superior dielectric strength and flame resistance. Improved Surface FinishEspecially in applications requiring visible or aesthetic finishes, short-fiber filled grades maintain a cleaner surface appearance.

6. Manufacturing Process of Glass-Filled Granules The manufacturing process typically includes: • Preparation of Glass FibersEnsuring consistent sizing and surface treatment compatible with PC resins such as 945 and 945U. • Blending with Polymer ResinUsing compounding equipment to evenly disperse glass fibers in grades like PC 20% GF FR and PC FR GRANULE. • PelletizationThe filled resin is cooled and cut into granules for convenient processing and uniform feedstock. • Quality ControlTesting is conducted for tensile strength, flame retardancy, & flow rate. Grades like 943A and 940A are quality-verified for consistency in high-demand applications.

7. Advantages of Glass-Filled Granules Glass-filled polymers offer several performance and commercial benefits: • Cost-EffectivenessUsing high-performance grades like 945AU or PC FR GRANULE can reduce long-term costs by extending part life. • Improved PerformanceFor applications needing structural integrity and thermal endurance, grades like PC 30% GF FR or 943A are ideal. • Design FlexibilityAvailable in various fiber loadings and flame-retardant formulations, such as PC 10% GF FR, PC FR V0, and 940A. • DurabilityEspecially in mechanical assemblies or electronics, grades like 945 and 945U ensure long-term performance in demanding environments.
