Isoprene rubber (IR), also known as synthetic natural rubber, has a series of unique characteristics and wide application fields.

Characteristics:

1. Similar to natural rubber: IR has physical and mechanical properties similar to natural rubber. It has excellent elasticity, tensile strength, and abrasion resistance. This makes it suitable for applications that require high flexibility and durability.

2. Good heat resistance: IR can maintain its properties at relatively high temperatures. It has better heat resistance than some other synthetic rubbers, enabling it to be used in environments with elevated temperatures.

3. Low-temperature flexibility: It also shows good flexibility at low temperatures, ensuring its performance in cold climates.

4. Chemical resistance: IR has certain resistance to chemicals such as oils, acids, and alkalis, which broadens its application range.

Application Fields:

1. Automotive industry: IR is widely used in the production of tires, rubber hoses, seals, and other automotive components. The excellent elasticity and abrasion resistance of IR make tires more durable and provide better grip on the road. Rubber hoses and seals ensure the tightness and reliability of various systems in vehicles.

2. Industrial products: In the industrial field, IR is used in the manufacture of conveyor belts, rubber rollers, and vibration isolators. Conveyor belts made of IR can withstand heavy loads and wear, while rubber rollers are used in printing, papermaking, and other industries. Vibration isolators help reduce vibrations and noise in machinery.

3. Medical applications: Due to its biocompatibility and flexibility, IR is also used in some medical products such as surgical gloves, catheters, and medical tubing. It provides a safe and reliable material for medical procedures.

4. Sports equipment: IR is found in sports equipment like tennis balls, golf balls, and athletic shoes. The elasticity of IR contributes to the performance and comfort of these products.

5. Electrical insulation: IR can be used as an electrical insulation material due to its good insulating properties. It is used in cables, wires, and electrical connectors to ensure the safety of electrical systems.
