The characteristics of composition and performance of food grade silicone tube.
![]()
Food grade silicone tube is made of high temperature resistant and synthetic rubber resistant to steam the good performance of the inner rubber layer, multi-layer cloth / clip wire / steel wire winding layer and the outer layer composition. According to the working temperature, pressure, and the safety requirements of the degree, the selection of synthetic rubber formula, the skeleton layer of different material, and according to the work environment (high temperature and fire etc.) can be external armor (asbestos, stainless steel belt) protective layer.
The characteristics of food grade silicone tube:
Food grade silicone tube with small diameter tolerance, high temperature resistance, hot water resistance, water vapor resistance performance is excellent, the tube body light, soft and durable and so on; 4 - up to 10 times the working pressure of food grade silicone tube minimum burst pressure.
Food grade silicone tube application:
High temperature resistant food grade silicone tube is widely used in petroleum, metallurgy, cement workplace, pharmaceutical, chemical, machinery and other industries with high heat or fire, can also be used to transport 150. Saturated steam or hot water below C.
Parameters of food grade silicone tube
Pressure: 7 bar within the general working pressure, higher burst pressures can reach 70 bar
Temperature: common temperatures in the range of -30 DEG ~+130 DEG, some imported hoses can even up to +210 DEG C
Resistance: common resistance coefficient is less than 109 ohm
Diameter and wall thickness: caliber and hose diameter, wall thickness often refers to the glue in the thickness, diameter refers to the largest outer circle.
The following parameters for some imported food grade silicone tube high pressure value.
Diameter (mm) wall thickness (mm) diameter (mm)
