PBT GF20 is a composite material. It starts with a semi-crystalline thermoplastic polymer called PBT (Polybutylene Terephthalate), which is known for its robustness but can be somewhat brittle and lack stiffness for structural applications. To overcome these limitations, 20% Glass Fibers (GF) are compounded into the polymer resin.
The glass fibers act as a reinforcing skeleton, dramatically improving the material's:
1.Tensile and Flexural Strength
Stiffness (Modulus)
Dimensional Stability (resistance to warping and creep)
Heat Deflection Temperature
This creates a material that is significantly more capable than unfilled PBT, making it suitable for demanding engineering applications.
Key Properties and Characteristics
1.High Mechanical Strength & Stiffness: The 20% glass fiber reinforcement provides excellent load-bearing capacity and resistance to bending and deformation under stress. This is its primary reason for use.
2.Excellent Heat Resistance: PBT GF20 has a high Heat Deflection Temperature (HDT), typically in the range of 200-215°C (392-419°F) at 1.82 MPa. This allows it to perform reliably in high-temperature environments, such as under-the-hood automotive parts.
3.Good Chemical Resistance: It resists a wide range of chemicals, including oils, greases, fuels, and many solvents. This makes it ideal for automotive and industrial applications where contact with lubricants and fuels is common.
4.Low Moisture Absorption: PBT absorbs very little moisture (<0.3%) compared to other engineering plastics like Nylon (PA66). This means:
5.Excellent Dimensional Stability in humid environments.
6.It can often be processed without pre-drying (though drying is still recommended for optimal results).
7.Fast Crystallization & Cycle Time: PBT crystallizes very quickly, which allows for fast injection molding cycle times. This increases production efficiency and lowers part cost.
8.Good Electrical Properties: It is a good electrical insulator, even at high temperatures and in humid conditions, making it a staple in electrical components.
9.Excellent Flowability: It has a low melt viscosity, meaning it flows easily into complex and thin-walled molds.
