1.    Primary Composition: Made primarily from polybutylene terephthalate, PBT bristle features a density of 1.3-1.4 g/cm³ and melts between 220-230°C.

    2.    Descriptive Features: PBT is celebrated for its superior strength, flexibility, fatigue resistance, and solvent resistance. It’s particularly unsuitable for alkaline environments, which makes it perfect for tapered filaments in specialized brushes.

    3.    Filament Crafting: PBT filaments are produced through melt spinning, where their tips are shaped to a unique sharp peak, making them suitable for high-precision brushes like those used in cosmetics and arts.

    4.    Material Composition: This durable polyester plastic contains benzene rings and ester groups, enhancing its hardness over materials such as nylon.

    5.    Fiber Properties: Known for high tensile strength, excellent heat stability, and low moisture uptake, PBT bristles are ideal for use in moist or humid conditions.

    6.    Broad Applications: PBT bristles, with their low water absorption, offer consistent stiffness in humid environments, providing a robust alternative to traditional materials.

    7.    Price Dynamics: Stability in PBT prices reflects its growing popularity and utility in the manufacturing sector.

    8.    Material Comparison: PBT outshines competitors like PP and PET in both durability and cost-effectiveness, as shown in recent material comparison studies.

    9.    Usage in the Paintbrush Industry: The flexibility, chemical resistance, and structural stability of PBT make it a preferred material for high-quality paint brushes, ensuring long-term performance and superior paint application.
