Homogeneous TPU Belt

​General Introduction to Homogeneous Conveyor Belt

Homogeneous Conveyor Belt is an advanced transmission solution, specially designed for industries that require high hygiene standards and operating performance, especially the food, seafood, confectionery and pharmaceutical industries. The biggest difference of this conveyor line is its layerless structure, monolithic molding, smooth and uniform surface from top to bottom, helping to completely eliminate the risk of contamination, fraying and microbial accumulation.

Structure without layers: Many benefits for use in water environments, food hygiene and safety

Structural characteristics

Homogeneous PU Conveyor Belts are manufactured entirely from thermoplastic polyurethane (TPU) material, without a reinforced burlap layer like traditional PU conveyor belts. Some high-end lines can reinforce the aramid or kevlar fiber core to increase bearing capacity and prevent elongation.

• No layer: Completely eliminates the risk of fraying, peeling, and contamination from the fabric layer.
• One-piece molding: No joints or gaps, making the surface absolutely smooth.
• Glossy/smooth surface: Easy to clean, does not stick to food, does not create conditions for microorganisms to grow.
• Waterproof, grease, and chemical resistant: Meets strict production environments.

Hygienic benefits

The structure without layers and gaps helps the PU conveyor belt to achieve uniformity and maximum hygiene, completely eliminating the risk of bacteria and mold entering the conveyor core. It is easy to clean with hot water and common cleaning chemicals without affecting the lifespan of the conveyor belt.

Advantages of monolithic casting technology

• High mechanical strength: No weak points due to joints or layers, can withstand large loads, and has good elasticity.
• Absolute uniformity: No layering, no peeling, waterproof, greaseproof.
• Easy to integrate accessories: Bezels, ruffles, ribs can be molded together, or additional accessories can be welded according to application requirements.

In particular, in food and seafood processing factories where absolute hygiene is required, uniform PU conveyor belts are the optimal choice to prevent the risk of cross-contamination, ensure food safety and extend product preservation time.

Transmission Mechanism: Smooth Pulley Running and Pulling Sprocket Running

Run the roller puly

Homogeneous PU Conveyor Belts can operate on the principle of friction transmission, similar to PU conveyor belts with ply layers. The lower surface of the conveyor belt is in direct contact with the pulley shaft, the pulling force is transmitted through friction between the belt and the shaft. The advantage of this method is smooth operation, suitable for applications with light loads, moderate speeds, and high hygiene requirements.

Run pulley wheels

In particular, the Homogeneous PU Conveyor Belts can also operate with a positive drive mechanism thanks to the Soliflex sprocket system. The underside of the conveyor belt is molded with lugs that run vertically or horizontally, meshing directly with the sprocket teeth, helping to transmit traction accurately, without slipping or deflecting the belt, suitable for large loads, high speeds or uphill and complex navigation applications.

• Advantages: No slipping like friction drives, self-aligning, reduces risk of belt misalignment, increases system life.
• Disadvantages: Requires synchronous sprocket design, precise hump arrangement, tooth pitch control and minimum diameter.

Compare two drive mechanisms

Criteria	Run the roller puly	Run pulley wheels
Transmission principle	Friction on the lower surface	Eating the hunchback - pronged tooth joint
Accuracy	Medium	Very high, no slipping
Load capacity	Reasonable	Big, stable
Anti-deflection ability	Alignment dependent	Self-aligning using central/marginal teeth

Soliflex Hump Sprocket: Center and Marginal Teeth Design

Soliflex hump sprocket design features

Soliflex sprockets are specialized sprockets for homogeneous PU conveyors, designed with two special types of teeth:

• Center bar: Ensures accurate transmission, increases self-alignment ability, and prevents belt misalignment when operating at high speeds or with heavy loads.
• Teeth close to the edge (full bar): Add the ability to hold the edge of the belt, prevent product overflow, and increase stability when the conveyor belt operates in changing positions, going uphill or loading loose materials.

Soliflex sprockets are usually manufactured from POM or UHMW-PE material, which has high hardness, abrasion resistance, chemical resistance and meets food safety standards.

Outstanding advantages

• Self-aligning: The design of middle teeth and edge teeth helps the conveyor belt always stay in the correct position, minimizing the phenomenon of belt misalignment and ice slipping.
• Increased longevity: Reduces wear, reduces load on transmission components, prolongs conveyor and sprocket life.
• Easy to maintain: Quick disassemble structure, easy to clean, suitable for strict hygiene requirements in the food industry.

Compatibility Between Homogeneous Conveyor Belt And Sprocket

Technical requirements when combined

To ensure optimal operation of the drive system, it is necessary to select the correct type of uniform PU belt and compatible sprocket sprocket.:

• Pitch: Must be synchronized between the hump on the belt and the teeth on the sprocket.
• Minimum sprocket diameter: Depends on belt thickness, hump height, ensuring bending radius does not exceed material limits.
• Number of sprockets: Evenly distributed according to belt width, minimum 2-3 sprockets for 150-300mm wide tape, gradually increasing with width to avoid belt sagging and misalignment.

Note when designing

• Arrangement of the hump: The hump must be cast accurately, evenly, without position deviation to ensure complete alignment with the sprocket teeth.
• Sprocket material: POM, UHMW-PE or stainless steel is preferred for corrosive and high temperature environments.
• Check synchronization: Before installation, it is necessary to carefully check the alignment between the hump and the sprocket teeth to avoid jamming, slipping or uneven wear.

Compare homogeneous PU conveyor belts, PU layered conveyor belts and Modular plastic conveyor belts

Criteria	Homogeneous PU	PU has three layers	Modular plastic conveyor belt

Homogeneous PU conveyor belts combine the hygienic advantages of PU conveyor belts, the durability and precise transmission capabilities of modular plastic conveyor belts, suitable for applications that require absolute hygiene, medium to large loads, and continuous operation..

Important Technical Specifications: Thickness, Tensile Force, Pulley Diameter

Conveyor belt thickness

• Popular: 1.5mm, 2.0mm, 2.5mm, 3.0mm, 4.0mm
• Choose according to load, bending radius, application requirements (light load choose thin, heavy load choose thicker).

Stretching force

• Typical parameters: 2–6 N/mm (depending on type, thickness, aramid core or not)
• The greater the tensile force, the higher the load-bearing capacity and better resistance to stretching.

Minimum pulley diameter

• Depends on ice thickness and hump/rib height.
• For example: 2mm PU requires a minimum pulley of 94.7mm, 3mm PU is 127.3mm, 4mm PU is 159.8mm.
• If there are tendons or burrs, it is necessary to increase the pulley diameter to avoid cracking at the tendon base/burrs when bending.
