What are the advantages of polyurethane (PU) conveyor belts?

Polyurethane (PU) conveyor belts have many advantages, such as good wear resistance, oil resistance, corrosion resistance, non-toxic and hygienic, light and soft, wide range of applications, environmental protection and energy saving, and easy maintenance. They are widely used in conveying systems in various industries.

Polyurethane (PU) conveyor belts have the following advantages:

Good wear resistance: Polyurethane materials have good wear resistance, can withstand high-intensity friction and wear, and effectively extend the service life of the conveyor belt.

Good oil resistance: Polyurethane materials are not easy to react chemically with oil substances, have good oil resistance, and can meet various oily environments in food processing.

Good corrosion resistance: Polyurethane materials have good resistance to corrosion by acids, alkalis, salts and other chemical substances, and can effectively resist the erosion of various chemical substances.
Non-toxic and hygienic: Polyurethane materials themselves are non-toxic and meet FDA food grade standards. They will not pollute food or cause harm to the human body.

Light and soft: Polyurethane materials have low density, light weight, good softness, easy installation and maintenance, and also easy cleaning and maintenance.
Wide range of applications: Polyurethane conveyor belts are suitable for the transportation needs of various industries, such as food, beverages, tobacco, medicine, electronics, etc., and can meet the special requirements of different industries.
Environmental protection and energy saving: Polyurethane materials can be recycled and reused, which meets environmental protection requirements and also has the effect of energy saving and consumption reduction.
Easy maintenance: Polyurethane conveyor belts are easy to maintain and have a long life. They can achieve efficient and stable transportation at a lower operating cost.

What chemicals are the corrosion resistance of polyurethane effective for?
It is effective for a variety of chemicals, as follows:

Acids: Most organic acids and inorganic acids, such as formic acid, acetic acid, hydrochloric acid, etc.
Alkali: Strong bases such as sodium hydroxide and potassium hydroxide, and some weak bases such as ammonia water.
Salts: Salt substances such as sodium chloride and potassium chloride are less corrosive to polyurethane.
Oils: Most oil substances such as lubricating oil and fuel oil are less corrosive to polyurethane.
Alcohols: Alcohol substances such as ethanol and methanol are less corrosive to polyurethane.
It should be noted that some strong oxidants, such as concentrated sulfuric acid and nitric acid, may corrode polyurethane, so it is necessary to avoid using polyurethane conveyor belts in some specific environments. At the same time, when selecting conveyor belt materials, it is necessary to comprehensively consider the actual application scenarios and requirements and select appropriate materials to ensure the stability and reliability of production.
