Polyurethane Belt Scraper Blades

Custom Urethane Scraper Blades: The Ideal Choice for Mining Conveyor Belt Cleaning

- Urethane scraper blades have a longer lifespan than traditional options—meaning fewer replacements and less operational downtime.

- Resist damage from harsh substances like acids, caustics, and oils—ideal for chemical or industrial environments.

- Polyurethane scraper blades minimize material buildup on conveyor belts, which prevents belt slippage and keeps machinery running smoothly.

INDUSTRIES SERVED: Coal Mining, Aggregate Processing, Mineral Processing

Pepsen has been manufacturing customized and high performance polyurethane scraper blades and belt cleaners. They are used in a wide range of industrial applications such as mining, construction, material handling, and food processing. To meet different working enviroments, Pepsen offers different polyurethane formula for high-temperature environments, heavy abrasion resistance, chemical resistance, or FDA compliance,

Blades can be manufactured entirely from polyurethane or bond urethane to metal for enhanced structural stability. Urethane scrapers offer significantly longer service life and superior overall performance than rubber ones. Besides, polyurethane’s natural resilience lets the blades absorb impacts and conform tightly to surface contours while avoiding damage to belts or clipper splices. A broad range of durometers is also available, ensuring optimal results whether you’re removing large aggregate or draining water from conveyor surfaces. With over 20 years' experience of bonding expertise, you can trust these blades to maintain reliable performance without delamination under heavy use.

Advantages of Polyurethane Belt Scraper Blades

- Exceptional Abrasion Resistance: Polyurethane’s toughness resists harsh conveyor cleaning, removing buildup without belt damage.

- Flexibility: Polyurethane conforms to belt curvature, ensuring full cleaning and less material carryover.

- Low Friction: Low friction lowers energy use and minimizes wear on both blades and belts.

Customizable: Hardness, color, formulations and shapes can be adjusted to fit various conveyor belt , making them suitable for diverse industries

Before-and-After Customer Results

Polyurethane scraper blades deliver measurable improvements for clients across industries.

- Biscuit Production Line

Before: Used rubber scraper blades that left dough residue on 1.2m-wide conveyors, requiring 45 minutes of manual cleaning after each 8-hour shift (risking production delays).

After: Switched to our food-grade polyurethane scraper blades—residue adhesion dropped by 70%, cutting manual cleaning time to 18 minutes per shift (a 60% reduction) and avoiding 2+ hours of weekly downtime.

- Coal Mining Conveyor (Australian Client)

Before: Relied on mild steel blades that wore out every 3 weeks (due to gravel abrasion) and caused belt scratches.

After: Adopted our 85A mining-grade polyurethane scraper blades—wear rate slowed to just 0.3mm per week, extending replacement cycles to 12 weeks (a 4x increase). Additionally, belt scratch incidents fell from 5/month to 0, reducing belt replacement costs by $12,000 annually.

- Dairy Processing Plant

Before: Rubber blades failed to remove milk fat from stainless steel conveyors, leading to 2 FDA compliance warnings in 1 year.

After: Installed our FDA-approved polyurethane scraper blades—fat residue was eliminated, and the plant maintained 12 consecutive months of compliance, with blade replacement intervals doubling from 2 to 4 months.
