Plastic Wedges for Paint Brushes – Stable Bundle Positioning & Consistent Production
Plastic wedges are installed inside the ferrule to tighten, support and position the bristle/filament bundle. They help improve brush shape consistency and long-term stability. Compared with traditional wooden inserts, plastic wedges provide better moisture resistance and tighter dimensional control, especially for water-based paint brush applications.
Key Benefits:
High consistency: ideal for mass production and automated/semi-automated assembly
Moisture-resistant: non-absorbing material helps reduce loosening or deformation in water-based paint use
Stable retention: improves bundle positioning and pressure distribution inside the ferrule
Wide compatibility:
suitable for both water-based paints and solvent-based coatings (material grade can be selected accordingly) Standard Sizes (Reference):
Width (mm): 14 / 29 / 42 / 54 / 62 / 66 / 85
Thickness (mm): 3.5 or 4.5
Diameter (mm): 50
Note: The table shows standard references (including volume and weight). Other sizes are available upon request.
Applications:
Paint brushes: flat brushes, angled brushes, etc. (wedge design matched to ferrule structure)
Coating systems: water-based paints, solvent-based coatings, varnish/wood coatings
Bristle/filament types: natural bristle, PBT/PET/nylon filaments, or mixed bundles
Material & Chemical Resistance (Options):
We can supply different plastic material grades to match coating systems:
For water-based paints: moisture-resistant and dimension-stable options
For solvent systems: suitable material grades can be selected based on solvent strength
Share your coating type, cleaning solvent and working conditions, and we will recommend the right material and provide samples for testing.
