Uses of Wear-Resistant Natural Rubber Sheets
We introduced DEF Rubber’s specialization in producing high-quality natural rubber sheets with over 95% natural rubber content. Their unique process and formula preserve the long-chain structure of natural rubber, resulting in excellent elasticity, wear resistance, and tear resistance, making it the best choice for wet grinding conditions. There are not many companies globally that can produce such wear-resistant natural rubber sheets. Notable ones include the linatex brand rubber products by Weir Rubber and natural wear-resistant rubber products by DEF Rubber. So, what are the main uses of these high-quality, wear-resistant rubber products? Here’s a simple introduction:
- Wear-resistant rubber lining for mining machinery and equipment:
This rubber’s primary application is to create wear-resistant rubber linings for various mining equipment, especially in coal mining machinery and equipment, such as ball mills, wear-resistant valves, slurry pumps (also known as sludge pumps), hydrocyclones, screening machines, spiral classifiers, mixers, flotation machines, gravity separators, magnetic separators, concentrators, dewatering machines, feeders, conveyors, iron removers, various wear-resistant pipe fittings and joints, and in gold mining equipment like air lifters, carbon screens, etc.
Wear-resistant Rubber Lining Processes:
There are two main processes for using wear-resistant natural rubber as lining in mining equipment:
- Cold Bonding Process: The wear-resistant natural rubber sheet is cut into the required size and shape according to the equipment and bonded at room temperature using special nitrile adhesive custom-formulated by DEF Rubber. This hand-operated process is widely applicable, especially for large-scale onsite rubber wear-resistant lining construction, although it requires experienced and skilled workers. DEF Rubber’s ultra-wear-resistant wet natural rubber sheet combined with custom adhesive offers strong adhesion and can be applied to almost any surface. Practice has proven that mining equipment with natural wear-resistant rubber lining significantly extends its service life, reduces noise, increases efficiency, and lowers maintenance costs.
- Molded Natural Rubber Lining: Different from the hand-cut and bonded process, this method uses custom molds to shape natural wear-resistant rubber into the required forms, directly installed inside the equipment. It is particularly suitable for small, complex-shaped, and batch-use equipment, such as wear-resistant rubber lining widely used in various slurry pumps by DEF Rubber.

Wear-resistant Rubber Lining Cases:
- Screening Machine Rubber Screen: In a certain mining washing and screening equipment, the original design used ordinary round steel welded screens for the upper layer and metal screens for the lower layer. After redesigning, the metal screens were replaced with high-elasticity wear-resistant natural rubber screens, featuring a multi-layer structure with nylon mesh in between. After the redesign, the onsite noise was significantly reduced, maintenance decreased, downtime was reduced, and equipment lifespan was greatly extended.
- Slurry Pump Rubber Sheath: A certain sand pump station primarily transported tailings slurry after ore beneficiation. The slurry, mainly composed of quartz particles, had a flow rate of 180m³ per hour, a pipeline length of about 500m, an output diameter of 150mm, multiple bends, and valves along the route, and a vertical height difference of about 10m. After replacing the pipe joints, valves, and slurry pumps with wear-resistant rubber lining, maintenance costs of wearable parts were reduced by more than half.
- Hydrocyclone Wear-resistant Rubber Lining: In a copper mine in China, the ore mainly contains magnetite, pyrrhotite, pyrite, etc., with a copper content of about 0.5% and slurry mud content of 10%. Using DEF Rubber’s wear-resistant rubber lining, the equipment lifespan significantly improved, with the rubber lining lasting more than twice as long as ordinary rubber.
- Water Absorption Rubber Strips for Cleaning Industry Floor Scrubbers:
As we know, the water absorption rubber strips for floor scrubbers have very high requirements for elasticity, wear resistance, and hardness. DEF Rubber’s unique formula and technology produce wear-resistant natural rubber sheets, making them the best material for manufacturing rubber strips for floor scrubbers under wet grinding conditions. They are moderately hard, highly elastic, and extremely wear-resistant. For oil-rich environments, there are specially developed polyurethane synthetic rubber sheets, with the oil-resistant rubber strips differing from the natural wear-resistant rubber strips in color, using a sky-blue translucent design for easy differentiation. The oil-resistant rubber strip products are also widely acclaimed among customers. - Other Fields:
Wear-resistant natural rubber, due to its wear-resistant and eco-friendly properties, is also used in other fields, such as rubber target backing for shooting ranges. Natural rubber’s high elasticity allows it to quickly recover after being penetrated by bullets. In animal rehabilitation centers, the walls of safety rooms are covered with wear-resistant natural rubber sheets. This material is not only safe and eco-friendly, but its good elasticity can prevent injuries when animals collide and resist damage from their teeth and claws. In other industrial fields, such as the manufacturing process of high-quality wear-resistant rubber timing belts, a layer of red wear-resistant rubber is often covered on the outer circle of the timing belt, significantly improving its elasticity and wear resistance. There are many other application scenarios for wear-resistant natural rubber sheets, and more are being discovered. DEF Rubber is eager to explore more possibilities with you.
Of course, each field may have different requirements for the performance and specifications of wear-resistant natural rubber sheets, including size, thickness, durability, and more. When selecting materials, you can discuss your usage requirements with the supplier to customize the most suitable wear-resistant natural rubber sheet products. Want to know more.
