Nylon (PA)
Material Characteristics
  • Long Service Life: Maintains structural integrity under frequent sweeping, outperforming most synthetic filaments.
  • High-Temperature Resistance: Melting point 215-260°C, stable at 80-120°C without deformation.
  • Physical Stability: Water absorption 3%-9% (only temporary stiffness reduction), rapid elastic recovery.
  • Chemical Resistance: Resists common solvents and weak acids (pH 4-8).
Technical Application Scope
  • Disc Brushes: Gentle carpet cleaning, no fiber damage.
  • Roller Brushes: High-temperature industrial scenarios (e.g., steel mills).
  • Sweeper Main Brooms: Rough ground (e.g., construction sites) with wear resistance.
Polypropylene (PP)
Material Characteristics
  • Efficient Cleaning: Decontamination rate >90% for light-moderate dirt (dust, oil).
  • Economic Advantage: 25%-35% cheaper than nylon, cost-effective for large-scale use.
  • Environmental Compliance: Recyclable, RoHS-certified.
  • Limitations: Melting point 160-170°C (no >60°C use), lower elastic recovery (15% less than nylon).
Technical Application Scope
  • Rental Disc Brushes: Low-frequency use for equipment rental companies.
  • Sweeper Side Brushes: Daily cleaning (residential areas, municipal roads).
  • Washing Machine Brushes: Non-toxic, suitable for household use.
Proex (Modified Polypropylene)
Material Characteristics
  • X-shaped cross-section: 20%-30% larger contact area; 18% higher unit-time decontamination.
  • Moisture-resistant: Mold-inhibited, no mildew in 80% humidity (3 months).
  • Anti-winding: X-structure cuts hair/fiber tangles; 50% less maintenance.
  • Limitation: Same heat resistance as regular PP (not for high temps).
Technical Application Scope
  • Wet-environment roller brushes (underground garages, pools: cleans water + dust).
  • Municipal sanitation side brushes (rainy-area roads: lower maintenance cost).
Steel Wire
Material Characteristics
  • Wear-resistant: High-carbon/304 stainless steel (HRC 45-50); removes oxide scales/welding slag.
  • Strong: 1200-1500MPa breaking strength (no breakage in heavy loads).
  • Limitations: Scratches smooth surfaces; carbon steel rusts in wet conditions (needs rust prevention).
Technical Application Scope
  • Grit rotary brushes (factory cement floors: removes 5mm-thick oil).
  • Steel mill brushes (steel billet oxide scale pre-treatment: replaces sandblasting).
  • Rust-removal brushes (ships/bridges: 304 stainless avoids re-rusting).

Union Fibre (Mixed Natural Fibers)

Material Characteristics
  • Eco-friendly: 60% Tampico + 40% Palmyra; biodegradable.
  • Dust-control: Absorbs 0.1-10μm dust; 80% less emission (good for clean rooms).
  • Soft: Shore D20-25; safe for precision instruments/cultural relics.
  • Limitations: 2-3 month lifespan; 15% water expansion (not for wet environments)
Technical Application Scope
  • Electronic factory brushes (semiconductor workshops: meets Class 1000 clean room standard).
  • Hotel marble brushes (avoids scratches).
  • Cultural relic restoration brushes (protects surfaces).
GRIT ROTARY
Material Characteristics
  • Nylon + silicon carbide: Flexible + abrasive; 5 customizable specs (large diameter = heavy dirt; fine particles = fine cleaning).
  • Cost-saving: Replaces stripping pads; 60% cheaper per clean; 200x longer lifespan.
  • Requirement: Must use wet (cools particles; dry use causes overheating).
Technical Application Scope
  • Mall terrazzo brushes (removes old wax; 20% gloss boost).
  • Factory epoxy floor brushes (cleans oil without coating damage).
  • Airport runway brushes (removes rubber residue; preserves flatness).
