When it comes to painting and finishing, the right bristle makes all the difference. Traditional synthetic filaments often look flat and plasticky, and they can lay down paint unevenly. PolyFil F is changing that. With a unique manufacturing process and smarter material science, it’s become a standout choice across the industry.

What is PolyFil F?

PolyFil F is made from PBT and PET. During melt extrusion, a proprietary additive creates a uniform micro‑porous structure inside each filament. Those micro‑pores deliver a soft, matte appearance and improve feel, weight, and other physical properties—surpassing conventional filaments in both form and function.

Five Core Advantages

Compared with standard paint brush filaments, PolyFil F elevates looks, handfeel, and real‑world performance. These five advantages hit the needs pros and DIYers care about most:

1. Matte finish for a premium look

Most filaments are glossy, which can look harsh—especially on furniture and walls where uneven glare is noticeable. Thanks to its internal micro‑pores, PolyFil F diffuses light for a naturally matte look. The surface reads smoother and more refined, eliminating “cheap shine” and lifting the overall quality of your finish.

2. Boar‑bristle feel with soft, conforming contact

Standard nylon can feel stiff, while natural boar bristle is costly and prone to deformation. PolyFil F is engineered to match the softness and spring of boar bristle. In hand, it’s delicately “lofty,” and on the surface it conforms more closely to walls and wood for better layoff.

3. Uniform filaments for fewer brush marks

Tight process control ensures consistent filament diameter and even micro‑pore distribution. That uniformity stabilizes paint pickup—no more over‑ or under‑loading. Combined with precise filament alignment, paint releases evenly to minimize streaks and banding.

4. Lighter weight, easier to clean

Because of its micro‑porous structure, PolyFil F is 3–5% lighter than comparable filaments made from the same materials. Brushes feel lighter in the hand and reduce wrist fatigue. The pore pathways also let water penetrate more readily, so a quick rinse cleans the brush and helps extend its service life.

5. Soft‑flex tough for durability

By fine‑tuning the additive ratio, PolyFil F hits the “soft but not floppy” sweet spot—about 5% softer than comparable filaments. It withstands repeated bending without the breakage you get from overly stiff filaments, yet maintains enough snap for control. The result: long‑lasting performance.

Where does it shine?

• Home renovation: Walls and furniture refreshes—matte for an upscale look, lighter weight to reduce fatigue.
• Furniture manufacturing: Excellent for fine woodgrain finishes with fewer brush marks.
• Industrial coating: Consistent paint load and release for uniform results at scale.
• Art and decorative work: Soft filaments for controlled strokes and smooth color transitions.
