Conveyor belts are ubiquitous in the industrial sector. Different types of conveyor belts are used depending on the type of machinery and working environment, including oil-resistant, non-slip, flame-retardant, and high temperature resistant conveyor belts.
Silicone conveyor belts are a highly active adsorption material. They are amorphous, insoluble in water and all solvents, non-toxic and odorless, chemically stable, and unreactive with all substances except strong bases. Silicone’s chemical composition and physical structure give it many characteristics that are difficult to replace with similar materials: high adsorption capacity, excellent thermal stability, chemical stability, and high mechanical strength.
As a result, silicone conveyor belts are widely used in the food industry and grain departments for transporting bulk, canned, and packaged grains, as well as biscuits, candy, fruit and vegetable processing, poultry, and meat processing.
Silicone conveyor belts are primarily composed of silicon dioxide, which is purified from natural minerals and processed into granular or beaded forms. Different manufacturing methods result in varying microporous structures, which have a strong affinity for water molecules. Silicone is best suited for hygroscopic environments such as warm temperatures (20-32%) and high humidity (60-90%), and can reduce relative humidity to around 40%.
Different types of silicone develop distinct microporous structures due to their varying manufacturing methods. Silicone’s chemical composition and physical structure give it properties that are difficult to replace with other similar materials.
Silicone conveyor belts offer heat resistance, corrosion resistance, dielectric properties, ozone resistance, atmospheric aging resistance, corrosion resistance, high lubricity, and electrical insulation.
Endless seamless silicone conveyor belts are vulcanized in a drum vulcanizer at high temperature in a single step. Post-treatment of the silicone surface ensures that the belts will not delaminate even under prolonged, high-temperature operation. They are highly resistant to high temperatures, have a narrow expansion range, and will not stick to the conveyed material even under prolonged, high-temperature operation.
Features of silicone conveyor belts include:
1. Food grade, widely used in the food industry.
2. High-temperature resistance, capable of operating in environments up to 150°C and capable of withstanding transient temperatures up to 200°C. Pure silicone conveyor belts offer greater high-temperature resistance.
3. They are non-stick, preventing them from sticking to sugary foods like candy and chocolate.
Silicone conveyor belts are widely used and highly favored in the food industry. We believe you now have an understanding of silicone conveyor belts and know how to choose one. If you require a conveyor belt, please contact our SCplus sales team or request a catalog and quote.
