Phenyl gum is a synthetic polymer material, also known as polystyrene gum or phenylpolystyrene. It has many important application areas, and the following are some of its main applications:

Plastic products: Phenyl rubber is widely used in the manufacturing of plastic products, such as plastic containers, bottles, toys, packaging materials, etc. Its advantages are high strength, durability, and good stability, which can be used in various plastic processing methods.
Electronic appliances: Phenyl rubber has a wide range of applications in the electronic appliance industry, such as in the manufacturing of TV casings, computer casings, household appliances, etc. Its insulation and mechanical properties make it an ideal material for electronic and electrical manufacturing.
Building materials: Phenyl rubber is used to manufacture building materials such as insulation, sound insulation, pipes, and fittings. In the field of construction, it is commonly used for insulation materials, such as insulation boards, insulation pipes, etc.
Packaging materials: Due to the excellent performance of phenyl rubber, it is widely used in the packaging industry. For example, used in the manufacturing of food packaging, pharmaceutical packaging, and other consumer product packaging.
Medical devices: Phenyl rubber can be used to manufacture medical devices and medical consumables. Its non-toxic and durable properties make it suitable for various applications in the medical field.
Automotive industry: Phenyl rubber also has important applications in the automotive manufacturing industry, such as in the manufacturing of automotive casings, components, interiors, etc.
Adhesive: Phenyl gum has a very strong adhesive ability, so it is widely used as an adhesive for bonding various materials.
Textiles: Phenyl rubber can be used for textile reinforcement, making textiles have better strength and durability.

It is worth noting that although phenyl rubber has a wide range of applications, it also has some potential environmental and health risks, especially in waste treatment and plastic recycling. Therefore, when using and handling phenyl rubber, attention should be paid to environmental protection and health and safety issues.
