Product Introduction
Donggang New Materials nail-polish-special brush filaments are standard core raw materials for bottled nail polish, UV gel, base coat, top coat and nail-art line-drawing paint brushes. Two mainstream materials with outstanding organic-solvent resistance: PBT and PA612, modified and enhanced for anti-swelling and anti-corrosion performance. Tapered-tip versions can draw French manicure edges, sketch lines and paint nail-art patterns, meeting both mass-production demands for commercial bottled nail polish and fine-detail requirements of professional nail-art brushes.

Exclusive Production Technology
Solvent-resistant substrate blending-modification process
Formulas optimized for nail-art solvent environments to improve fiber anti-corrosion and hydrolysis-resistance performance.
Precision extrusion & forming
High-precision dies strictly control single-filament diameter tolerance. Low-temperature whole-process processing preserves molecular-structure stability.
Multi-Dimensional Customization Services
Specification Customization: customizable filament diameter and cut-to-length.
Tip-Shape Customization: multiple finishing options: flat cut, single-end tapering, double-end tapering, rounded arc tips.
Material-Grade Customization: cost-effective general-purpose PBT or premium high-solvent-resistance PA612.
Color Customization: basic solid black & white; integral co-extruded dye-free colored bristles.
Main Application Scenarios
OEM bottle-cap brush heads for bottled nail polish / UV gel
Standard wide flat-tip brushes for large-area color application of solid-color nail polish, base coat, top coat and strengthening gel. Standard consumables for mainstream nail-polish bottles on the market.
Brush heads for professional nail-art paint brushes
Ultra-fine conical-tapered filaments for line-drawing brushes, outlining pens, rhinestone-picking brushes and French-manicure pens. Specially used for hand-painted patterns and fine-edge detailing in nail salons.
Mini travel-size nail-art brushes
Small brush heads for sample-size split-packed nail polish and disposable nail-art kits.
Core Factory Advantages
1. Dedicated fully-automatic integrated production lines for nail-art-brush-filament extrusion, wire-drawing and setting. Multiple utility-model patents for solvent-resistant ultra-fine-fiber wire-drawing technology with stable and sufficient monthly capacity.
2. Fast order arrangement for standard black PBT stock items. Reserved exclusive production lines shorten lead-time for premium PA612 and custom colored-tapered orders.

Frequently Asked Questions (FAQ)
Q1: What is the MOQ and how to apply for samples?
A1: Standard MOQ is 200 kg. Small trial orders are available for standard in-stock specifications. Samples are free of charge; the client only bears shipping fees. Samples will be dispatched within 7-10 working days.
Q2: How do I choose between PBT and PA612?
A2: Select PBT filaments for mass-produced ordinary nail polish for higher cost-efficiency. Choose PA612 filaments for premium UV gel and professional nail-art brushes exposed to long-term nail-polish-remover immersion for superior solvent resistance.
Q3: Will bristles bleed color and contaminate gel under immersion in nail polish?
A3: Colors are formed via integral masterbatch co-extrusion without surface-coating dyes. No color leaching or nail-product contamination occurs under long-term organic-solvent immersion. Stability greatly outperforms post-dyed bristles.
Q4: What processing-temperature should be observed during manufacturing?
A4: Drying and setting temperature after tufting shall be ≤100 ℃. Excessively high temperature will damage fiber molecular structure and degrade resilience and solvent-resistance performance.
Q5: Can ultra-fine tapered line-drawing styles be produced?
A5: Single-end progressive tapering for 0.05 mm ultra-fine filaments is fully supported. Finished brush heads are slim and sharp for precise fine lines and patterns in nail-art, making them the preferred raw-material for professional nail-art brushes.
