PBT Compounds – Brief

PBT (Polybutylene Terephthalate) compounds are engineering plastics made by modifying base PBT with additives to enhance performance.

👉 Simple: PBT + additives (GF, FR, color, UV) = PBT Compound

🔹 Key Properties

High strength and rigidity
Excellent electrical insulation
Good heat resistance
Low moisture absorption
Good dimensional stability

🔹 Common Additives Used

Glass Fiber (GF) → increases strength and stiffness
Flame Retardant (FR) → improves fire safety
UV Stabilizers → protection from sunlight
Color masterbatch → for different colors

🔹 Applications

Electrical and electronic components (connectors, switches)
Automotive components
Appliance parts
Industrial components

PBT Plain (Black & Natural)

Black PBT: Colored with black masterbatch
Natural PBT: Off-white / natural without added color

🔹 Key Features

Good strength
Excellent electrical insulation
Suitable for general-purpose applications

🔹 Applications

Electrical components
Automotive parts

PBT Glass Filled (GF 15%, 20%)

PBT Glass Filled (GF):
PBT material reinforced with glass fibers (15% / 20%) to improve performance

🔹 Key Features

Higher strength & stiffness
Improved heat resistance
Excellent dimensional stability
Better mechanical performance compared to plain PBT

🔹 Applications

Electrical connectors
Housings
Structural parts

PBT Flame Retardant (FR V0, V1, V2)

PBT material modified with fire-resistant additives to enhance safety in demanding applications.

🔹 Flame Rating Levels

V0 → Highest flame resistance
V1 → Medium flame resistance
V2 → Basic flame resistance

🔹 Key Features

Improved fire safety
Self-extinguishing properties
Suitable for electrical and electronic applications

🔹 Applications

Electrical safety components
Electronic devices
Connectors and switches
