Harnessing Synthetic Fibers: The Shift to PBT and PET in Paintbrush Manufacturing

The rising costs of traditional materials like boar bristles are driving the paintbrush industry towards synthetic fibers. PBT and PET polymers are at the forefront of this shift.

    •    PBT (Polybutylene Terephthalate): This component is celebrated for its elasticity and softness, essential for brushes that require a delicate touch. It withstands temperatures up to 150°C and maintains excellent mechanical stability.
    •    PET (Polyethylene Terephthalate): PET excels in providing the stiffness needed for more robust painting applications, albeit with less flexibility than PBT.

Utilizing a mix of PBT and PET allows for paintbrushes that are both durable and flexible, catering to a wide array of painting needs. This blend is particularly effective when tapered chemically for superior paint distribution.

Typical applications include:

    •    Diverse Brush Types: These synthetic fibers are used in everything from household brooms to professional artist brushes.

The preferred ratio in the industry is often 30% PBT and 70% PET, striking a perfect balance between softness and rigidity. Additionally, our company offers customized ratios, providing unique solutions that help our clients stand out in a highly competitive market.
