Product Introduction
1. Overview
This PBT Glass Fiber Reinforced Compound is a high-performance engineering thermoplastic designed for applications requiring excellent mechanical strength, rigidity, and dimensional stability. With 20% to 30% glass fiber content, this grade offers superior heat resistance and creep resistance compared to unfilled PBT. It is a non-flame retardant (General Purpose) grade, ideal for applications where flame retardancy is not required.
2. Key Features
High Strength & Stiffness – Reinforced with 20%-30% glass fiber for enhanced mechanical properties.
Excellent Heat Resistance – High heat deflection temperature (HDT) suitable for under-hood and high-temperature environments.
Good Dimensional Stability – Low moisture absorption, minimal warpage, and excellent part-to-part consistency.
Chemical Resistance – Resists oils, greases, and many solvents.
Non-FR Grade – Cost-effective solution for general industrial applications without flame retardant additives.
Easy Processing – Suitable for injection molding with good flowability.
