Polycarbonate Glass-Filled Granules: Properties, Uses, and Applications

1
Polycarbonate Glass-filled Granules Properties,
Uses And 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.

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.

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.

• 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.

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.
