Polyurethane Cleaner Scraper
- Service life 3 to 4 times longer than conventional alloy rubber scrapers — and up to 5 times longer when ultra-wear-resistant polyurethane composite material is specified
- Precision-molded polyurethane compound delivers a smooth, bubble-free, burr-free blade surface for consistent full-width belt contact without localized pressure points
- Low friction coefficient combined with high elasticity allows the blade to maintain stable, controlled contact force against the belt surface — cleaning effectively without accelerating belt cover wear
- Modular split-blade design enables individual blade segments to be replaced independently, reducing maintenance time and eliminating the need to disassemble the full scraper assembly
- Strong chemical resistance and anti-fracture properties make polyurethane blades suitable for corrosive, wet, and chemically active material handling environments
Product Introduction
The polyurethane cleaner scraper blade is the primary functional component of any belt conveyor cleaning system. Its role is straightforward but operationally critical: to remove adhered material, coarse particles, and surface contamination from both the carrying face and return face of the conveyor belt before the belt re-enters the loading zone or wraps around return pulleys.
MinsenMine polyurethane cleaner scrapers are manufactured from high-molecular-weight polyurethane compound, selected for its combination of properties that no single alternative material delivers together: the hardness and abrasion resistance to remove tough adhered material, the elasticity to conform to belt surface variations without gouging, the low friction coefficient to minimize belt surface heat and wear, and the chemical resistance to perform in the full range of industrial material handling environments.
High-Molecular-Weight Polyurethane
Smooth, dense, bubble-free blade surface combining hardness, elasticity, and abrasion resistance — the material benchmark for industrial belt scraper applications.
3–5× Longer Service Life
Outlasts alloy rubber scrapers by 3 to 4 times as standard — and up to 5 times longer when ultra-wear-resistant polyurethane composite is specified.
Modular Split-Blade Design
Individual blade segments replace independently without disassembling the full assembly — cutting maintenance time and reducing replacement material cost.
Anti-Fracture & Chemical Resistance
Flexible molecular structure resists tip fractures at belt splices and fasteners, while strong chemical resistance ensures consistent performance in wet, corrosive, and chemically active environments.
Product Structure & Working Principle
Polyurethane chemistry, modular blade geometry, and dual-position design — how each element contributes to reliable belt cleaning.
High-Molecular-Weight Polyurethane Compound
The blade material is formulated from high-molecular-weight polyurethane, producing a smooth, dense surface free of bubbles and surface defects.
Modular Split-Blade Architecture
Each scraper assembly uses a segmented blade design in which individual blade sections are independently mounted on the carrier bar.
Inline Blade Geometry for Primary Position
The primary scraper blade uses a straight inline profile to distribute contact force evenly across the full belt width at the head pulley.
Anti-Fracture & Chemical Resistance
Polyurethane’s molecular flexibility prevents the blade tip fractures and edge chipping that brittle alloy or hard rubber scrapers commonly experience when contacting belt splices, fasteners, or surface irregularities.

Certified to the Highest Industry Standards
Wherever belt conveyors carry material, polyurethane scraper blades keep the system clean.
Polyurethane blade quality is determined at the compounding and molding stage — not at installation. Inconsistent molecular weight, air inclusions in the blade body, or dimensional variance in the blade profile all translate directly into uneven belt contact, premature wear, and cleaning failure. MinsenMine polyurethane cleaner scrapers are produced under a certified quality management framework with material and dimensional specifications controlled at every stage of production.
Our Certifications Include:
MA Certification (Mine Product Safety Mark)
Confirming compliance with national safety standards for underground and surface mine applications
ISO 9001 Quality Management System
Certified quality management system covering material specification, production, and inspection
SGS Factory Certification
