High Temperature resistant fire sleeve widely serves in petrochemical industry
Injection molding machine is one of the most used equipment. While the material handing hose on the machine is an important part. This hose is to deliver raw materials to the machine. Thus it should have high and stable performance. In fact, there are various materials for such hose. Let me introduce you some of the most popular ones next.
Rubber
Rubber hoses are widely used in injection molding machines. Because they have high tensile strength, wear and aging resistance. The inner layer is synthetic rubber with good wear resistance. While the outer layer is natural rubber that is resistant to aging and wear. However, during use, it is affected by factors such as temp, oxidation and UV ray. Besides, it is easy to age and harden, which can affect its service life.
Plastic
Plastic hoses have become the mainstream material. Because they have excellent chemical, wear and high temp resistance. While the main types include PVC, PU, PE and PTFE.
PVC hose has good wear and corrosion resistance. In addition, PVC pipe has a long service life. Besides, the price of PVC hose is lower than other materials. Thus PVC duct hose is the most popular one for injection machine. PU hose has high tensile strength and good wear resistance. Besides, it can work at high pressure and high temp conditions. PE hoses have excellent UV and aging resistance. Thus it is ideal for outdoor exposure situations.
Metal
Metal hoses have tensile strength and pressure resistance. Thus they are suitable for high pressure, high temp and high flow rate conditions. Metal hoses include stainless steel hose and carbon steel hose. Stainless steel hose is corrosion resistant and suitable for chemical, food and other industries. While carbon steel pipe has excellent tensile strength and wear resistance. Then it is suitable for construction, petroleum and other industries.
