Hopper liner

UHMW PE hopper liner is a type of plastic liner that is used to protect the inner surface of hoppers from abrasion and corrosion caused by bulk materials. Hoppers are containers that store and discharge materials such as coal, sand, gravel, cement, etc. They are often used in industries such as mining, construction, agriculture, and chemical processing. UHMW PE stands for ultra-high molecular weight polyethylene, which is a thermoplastic polymer with high impact strength, low friction coefficient, and excellent wear resistance. UHMW PE hopper liner has many advantages over other types of liners such as steel or rubber. Some of these advantages are: - UHMW PE hopper liner reduces the friction between the material and the hopper wall, which improves the flowability and prevents clogging or bridging of the material. - UHMW PE hopper liner reduces the noise level and vibration caused by the material movement inside the hopper, which enhances the working environment and safety. - UHMW PE hopper liner resists corrosion from chemicals and moisture present in the material or environment, which extends the service life of the hopper and reduces maintenance costs. - UHMW PE hopper liner is easy to install and replace due to its light weight and flexibility. It can be cut to fit any shape or size of hopper with simple tools.

What is the UHMW PE Hopper Liner:

If you are looking for a durable and low-friction material to line your hoppers, chutes, silos, or other bulk material handling equipment, you may want to consider UHMW PE (ultra high molecular weight polyethylene). UHMW PE is a thermoplastic polymer that has exceptional abrasion and impact resistance, as well as a low coefficient of friction. It can withstand harsh environments and reduce wear and noise on your equipment.

UHMW PE stands for ultra high molecular weight polyethylene. It is a type of plastic that has very long molecular chains, which gives it unique properties. UHMW PE has a molecular weight of 3 to 6 million g/mol, compared to 300 to 500 thousand g/mol for standard polyethylene.

The high molecular weight of UHMW PE results in:

- High abrasion resistance: UHMW PE can withstand repeated sliding and rubbing against hard surfaces without wearing out or losing its shape.
- High impact resistance: UHMW PE can absorb shocks and impacts without cracking or breaking.
- Low coefficient of friction: UHMW PE has a smooth surface that reduces friction and sticking between materials.
- Chemical resistance: UHMW PE can resist most acids, bases, solvents, oils, and fuels.
- Temperature resistance: UHMW PE can operate in temperatures ranging from -40°C to 80°C (-40°F to 176°F).
- UV resistance: UHMW PE can resist degradation from sunlight and weathering.


UHMW PE is an ideal material for hopper liners because it combines high durability with low friction. It can protect your equipment from wear and tear while ensuring smooth material flow. It can also reduce noise levels by dampening vibrations.


- Long service life: UHMW PE hopper liners can last up to 10 times longer than steel liners due to their high abrasion resistance.
- Cost savings: UHMW PE hopper liners can reduce maintenance costs by minimizing downtime and repairs. They can also lower energy costs by reducing drag force on conveyors or motors.
- Easy installation: UHMW PE hopper liners are lightweight and flexible. They can be cut into any shape or size with standard tools. They can be attached to metal surfaces with bolts,
screws, adhesives, or welding.


UHMW PE hopper liner is available in different grades depending on the application requirements. Some common grades are:

- Virgin grade: This is the purest form of UHMW PE with no additives or fillers. It has the highest impact strength and wear resistance among all grades. It is suitable for applications where high performance and durability are required.
- Anti-static grade: This grade contains carbon black or other conductive additives that dissipate static electricity generated by friction between materials. It prevents sparks or explosions that may occur due to static buildup in some materials such as coal or grain. It is suitable for applications where fire safety is a concern.
- UV resistant grade: This grade contains UV stabilizers that protect UHMW PE from degradation caused by exposure to sunlight or ultraviolet radiation. It prevents cracking or fading of UHMW PE due to UV rays. It is suitable for applications where outdoor use is involved.

UHMW PE hopper liner is a cost-effective and reliable solution for protecting hoppers from wear and tear caused by bulk materials. It improves the efficiency and safety of material handling operations while reducing downtime and maintenance costs.
