As the cost of natural boar bristles increases, there is a growing preference for synthetic alternatives. PBT (Polybutylene Terephthalate) and PET (Polyethylene Terephthalate) are two polymers extensively used in this domain.

    •    PBT: Offers excellent softness and elasticity, making it suitable for brushes that must be gentle yet effective. It also has superior heat resistance and mechanical properties. 

    •    PET: Provides the necessary stiffness for brushes used on more demanding surfaces, with reduced elasticity but increased durability.

In the industry, the synergy between PBT and PET enhances the functionality of paintbrushes, merging PBT’s flexibility with PET’s rigidity. This blend results in brushes that can handle both detailed artwork and larger surface coatings effectively.

Common uses include:

     •    Various Brushes: From artist to industrial brushes, PBT and PET are integral in diverse applications.

A common choice among manufacturers is a 30% PBT to 70% PET ratio, which offers optimal resilience and firmness. We also specialize in tailored blends to cater to specific market needs, empowering our clients to lead with innovative products in a competitive landscape.
