Do you Know What a Silicone Conveyor Belt is?

34 Published by Pure Technology Co., Ltd 5 月 15,2025

Silicone conveyor belt introduction

Silicone conveyor belts are highly active adsorption materials. They are amorphous substances whose chemical formula is mSiO2·nH2O.

Silicone conveyor belt is a transmission device widely used in various mechanical equipment. Its unique material and characteristics make it important for many fields.

Silicone conveyor belt material

Silica gel is a highly active adsorption material. It is an amorphous material. It is insoluble in water and any solvent. It is non-toxic and tasteless. It has stable chemical properties and does not react with any substance except strong alkali and hydrofluoric acid.

The silica gel conveyor belt’s elastomer is made of high-quality silicone rubber raw materials, and the skeleton material is made of high-strength, low-elongation, specially treated polyester fabric, which is suitable for conveying between low and high temperatures.

It is a new type of high-performance, multifunctional composite material.

Characteristics of silicone conveyor belt

1: Food grade, because the silicone conveyor belt is environmentally friendly and harmless, it is a food-grade material, so it is widely used in the food processing industry

2: High temperature resistant, because of its stable chemical properties, it can be used in an environment of -10°-200°, using the overall silicone form or coating on the surface of the silicone coated conveyor belt, it can convey products in a high-temperature environment and is commonly used in food equipment, food factories, and drying machinery, etc.

3: Strong anti-stickiness, because the nature of silicone makes it particularly anti-sticky, especially suitable for use in scenes such as chocolate factories that are easy to stick to the bottom.

Silicone conveyor belts have strong insulation, ozone resistance, weather resistance, radiation resistance, and non-stick surface (anti-stick); can withstand general acids, alkalis, salts, inorganic substances, and animal and vegetable oils; have outstanding high and low-temperature resistance, excellent elasticity, and easy to clean.

The shape of the silicone conveyor belt

The appearance color of silicone coated belt is milky white, the common thickness is 2-5MM, and special quantities can be customized. It can be made into rolls or endless belts. Connection method: hot pressing joint, the joint is flat, and it can also be connected with metal buckles.

What are the advantages and disadvantages of silicone conveyor belts?

Advantages:

  1. Food grade, this feature is an important reason why it is used in the food industry;
  2. High-temperature resistance, silicone belts can withstand high temperatures of 100-500 degrees, and the chemical properties are stable.
  3. Anti-stick, silicone belts do not stick to sugar, chocolate, and other foods with high sugar content.

Disadvantages:

  1. Expensive, silicone conveyor belt is more expensive than ordinary conveyor belts;
  2. Low hardness, so most of the conveyor belts in the oven use Teflon mesh belts/cloths;
  3. Poor roller performance, silicone belts have no lateral stability, and the material is relatively soft.

Application of silicone conveyor belt

Food processing industry

Silicone conveyor belts are widely used in the food industry because they are resistant to high temperatures and can be used in an environment of 150°C.

They also have anti-stick properties. After using the conveyor belt, the time to clean up the residual dough is shortened from 15 minutes per hour to 3 minutes.

Electronic manufacturing industry

The circuit board production line uses customized high temperature silicone conveyor belt, and the component offset rate in the reflow soldering process is reduced from 0.7% to 0.05%, thanks to the material’s high-temperature resistance and no contamination of precision parts.

Semiconductor processing: Many chip packaging lines are equipped with anti-static silicone belts, because silicone conveyor belts can avoid damage to sensitive components caused by electrostatic breakdown accidents, and the yield rate is stable at more than 99.93%.

Battery manufacturing: Data from the lithium iron phosphate battery workshop of a company we cooperated with showed that the service life of silicone conveyor belts in a strong acid electrolyte environment is 18 months, which is 3 times that of ordinary materials.

Silicone belt application

Packaging and logistics

Automated packaging line: used for sorting, packing, and other links, the non-slip surface can stably transport lightweight or special-shaped items.

Heat sealing equipment: A high-temperature resistant conveyor belt works with a heat sealer to avoid adhesion of high-temperature molten materials.

Textile industry

Dyeing and drying: In the drying process after dyeing and printing of textiles, high-temperature resistant silicone conveyor belts can stably transport fabrics, avoid deformation or adhesion due to high temperature, and resist corrosion from dye vapor.

The smooth surface prevents wet fabrics from scratching due to friction during drying.

Heat setting and calendering: In the fabric heat setting machine or calendering machine, silicone conveyor belts can withstand high pressure and high temperature, maintain dimensional stability, and prevent fabric shrinkage or wrinkling.

Silicone conveyor belts have become the preferred solution for industries such as food processing, electronic manufacturing, and medical sterilization due to their core advantages such as food-grade safety, resistance to extreme temperatures,anti-sticking, and easy cleaning.

As a leading silicone conveyor belt manufacturer in China, our company has been deeply involved in the industry for more than ten years. Our products have passed global authoritative certifications and support customized services.
