In conveyor systems, effective belt cleaning is essential for stable operation, lower maintenance costs, and reduced material carryback. A well-designed scraper component helps keep the belt surface cleaner, protects downstream equipment, and supports overall production efficiency. That is why choosing the right scraper rubber is an important part of any reliable conveyor cleaning solution.
CAB Green Scraper Rubber is designed for this purpose. As a durable three-ply combi scraping rubber, it combines wear resistance, elasticity, and belt-friendly performance in one structure. It is suitable for secondary cleaning duties and can be used as a dependable secondary cleaner rubber blade in demanding bulk material handling environments.
CAB Green Scraper Rubber is a specially engineered scraper rubber used in conveyor belt cleaning systems. It is developed to remove residual material from the belt after primary cleaning, helping improve belt cleanliness and reduce buildup along the line. Its design makes it especially suitable for applications where both cleaning performance and belt protection are required.
Unlike standard single-layer rubber products, CAB Green Scraper Rubber features a three-ply combi scraping rubber structure. This layered design gives the product a more balanced performance profile, allowing it to handle wear, absorb pressure, and maintain stable contact with the belt surface. For operations that need a reliable conveyor belt scraper material, this structure offers a practical advantage.
One of the most important features of CAB Green Scraper Rubber is its three-layer construction. This is not only a design feature, but also the reason why the product performs well under varying conveyor conditions.
The outer layer is wear-resistant, which helps the blade withstand continuous contact with the moving belt and abrasive materials. This improves service life and keeps the cleaning edge effective over time. The middle layer is elastic, allowing the rubber to respond better to belt movement, surface variation, and working pressure. This flexibility supports more consistent cleaning without excessive belt damage. The third layer adds support and stability to the whole structure, helping the blade maintain its form during operation.
Because of this combination, CAB Green Scraper Rubber works as a three-ply combi scraping rubber rather than a simple replacement blade. It delivers a more balanced mix of durability and adaptability, which is valuable in secondary cleaning systems.
CAB Green Scraper Rubber offers excellent wear resistance, making it suitable for continuous use in abrasive working environments. This helps reduce replacement frequency and lowers long-term maintenance demands.
It is also very belt-friendly. In many conveyor applications, cleaning efficiency must be achieved without causing unnecessary belt wear. CAB Green Scraper Rubber is designed to maintain effective contact while remaining gentle on the belt surface, which helps extend belt service life.
Another key feature is its low friction performance on conveyor belts. Lower friction can help support smoother system operation and reduce unnecessary resistance during cleaning. This is especially useful where stable and efficient belt running is important.
The product is available in different thicknesses from 15 mm to 40 mm, with production widths up to 2,000 mm. This allows the scraper rubber to match different cleaner designs and conveyor requirements more easily.
It is also designed for a temperature range of -45°C to +70°C. This wide range supports reliable use in both cold and warm operating conditions, making it a flexible choice for many industries.
In addition, the combi scraper rubber may protrude from its support by up to 1.5 times its thickness. This feature contributes to practical installation and effective blade positioning in suitable cleaner assemblies.
The table below provides a clear overview of the main technical parameters of HP-CAB. These specifications reflect the product’s three-ply structure and help explain its balance of wear resistance, flexibility, and stable cleaning performance in conveyor belt applications.

These technical characteristics make HP-CAB a reliable scraper rubber choice for secondary cleaning systems, especially in applications involving granular, slightly sticky, and moist materials.
The greatest practical benefit of CAB Green Scraper Rubber is that it balances cleaning efficiency with service life. Some scraper materials clean aggressively but wear quickly. Others last longer but do not adapt well to belt conditions. CAB Green Scraper Rubber is designed to reduce this trade-off through its layered construction.
Its wear-resistant surface helps extend operating life, while the elastic inner layer supports better contact with the belt. This means more consistent cleaning performance and fewer interruptions for blade replacement. For operators, this can translate into lower maintenance costs and more stable day-to-day performance.
Another important advantage is belt protection. Because the product is belt-friendly and designed with controlled flexibility, it can support effective cleaning without creating unnecessary belt stress. In practice, this helps users maintain cleaner belts while protecting a more valuable system component.
CAB Green Scraper Rubber is universally applicable as a scraper for granular, slightly sticky, and moist materials. This makes it a practical solution across a wide range of bulk handling conditions.
For granular materials, the product provides reliable removal of residual particles from the belt surface. In these conditions, wear resistance is especially important because abrasive contact can shorten blade life. The durable outer layer helps address this need.
For slightly sticky materials, flexibility becomes more important. The elastic middle layer allows the blade to maintain better working contact, helping remove material more effectively and reducing carryback.
For moist materials, a stable and adaptable conveyor cleaning solution is essential. CAB Green Scraper Rubber offers a balanced design that supports dependable cleaning performance even when material behavior becomes less predictable.
Because of these characteristics, it can be used in industries such as mining, aggregates, cement, ports, and other bulk material handling operations where conveyor belt cleanliness directly affects productivity.
In a conveyor cleaning setup, the primary cleaner typically removes the majority of material from the belt. However, some fine residue or remaining carryback often stays on the belt surface. This is where a secondary cleaner becomes important.
CAB Green Scraper Rubber is well suited for this stage. As a secondary cleaner rubber blade, it helps remove the remaining material more precisely after primary cleaning has already taken place. Its layered structure allows it to perform this task with both strength and flexibility, which improves cleaning consistency.
When used in compatible systems such as HP-R1, CAB Green Scraper Rubber supports more effective secondary cleaning by combining durability, adaptability, and belt-friendly contact. This makes it a valuable component in maintaining cleaner belts and reducing material buildup along the return side of the system.
To keep any secondary cleaner rubber blade performing well, regular inspection is important. Users should check the wear condition of the cleaning edge and confirm that the blade maintains proper contact with the belt. A worn or uneven edge may reduce cleaning efficiency and should be addressed in time.
It is also useful to monitor the overall condition of the rubber layers. Because CAB Green Scraper Rubber is built as a three-ply combi scraping rubber, visible changes in the structure can help indicate service condition and replacement timing.
Keeping the cleaner assembly properly adjusted is another key point. Good blade material performs best when supported by correct installation and operating pressure. Combined with routine maintenance, this helps extend service life and maintain cleaning performance.
CAB Green Scraper Rubber is a well-rounded product designed for efficient and dependable conveyor belt cleaning. As a three-ply combi scraping rubber, it combines a wear-resistant outer layer, an elastic inner layer, and a supportive structure to deliver strong overall performance.
Its main strengths include excellent wear resistance, belt-friendly operation, low friction, dimensional flexibility, and suitability for a wide temperature range. These features make it an effective scraper rubber for applications involving granular, slightly sticky, and moist materials.
