Physical Property

1. Exceptional Bending Strength

As one of the most durable monofilaments among thermoplastics, PolyFil™E offers outstanding cost-performance balance. It combines high creep resistance with strong chemical stability, making it a reliable animal-hair substitute—particularly ideal for paintbrush applications.

2. Superior Fatigue Resistance

Designed to endure repetitive use, PolyFil™E delivers excellent anti-fatigue and abrasion resistance. It maintains form and performance even after extended use, ensuring consistent efficiency for broom and brush products.

3. High Rigidity & Versatile Adaptability

Engineered for high stiffness, long-term durability, and stable heat performance, PolyFil™E exhibits a water absorption rate exceeding 10%, enhancing its hydrophilicity. This makes it a great fit for household cleaning, industrial scrubbing, and abrasive brush applications, even in high-temperature conditions.

Application

1. Paintbrushes

PolyFil™E offers superior liquid absorption and release, enhanced by our proprietary filament-tip forming technology. It reduces material loss and improves manufacturing efficiency while remaining eco-friendly. The bristles deliver a smooth, even coating and a refined finish — combining firmness and flexibility to ensure invisible brush marks and a flawless painting experience.

2. Brooms

With excellent toughness, abrasion resistance, and chemical stability, PolyFil™E bristles remain intact even in harsh acidic or alkaline conditions. Their superior fatigue endurance prevents deformation over time, ensuring reliable sweeping performance and long-term durability.

3. Household Cleaning Brushes

Highly resistant to common cleaning agents and disinfectants, PolyFil™E maintains structural integrity against chemical aging. This makes it an ideal choice for daily-use cleaning brushes, providing longer lifespan and exceptional reliability.

4. Industrial Cleaning & Polishing

Built for high rigidity and wear resistance, PolyFil™E is the perfect fit for industrial cleaning, polishing, and deburring brushes. It performs consistently under high-frequency, high-intensity operations, offering extended service life and stable performance in demanding industrial environments.
