Silicone rubber tubing and PVC tubing are two common types of tubing used in industry and in life, each with their own unique properties and applications. Understanding their differences can help in choosing the most suitable material for a particular need.

Material Characteristics

Silicone rubber tubing is made of silicone, which has excellent high temperature resistance and can work stably in a temperature range from -60°C to +200°C. It has a high temperature resistance of -20°C to +20°C. It has a high temperature resistance of -20°C to +20°C. It has excellent flexibility, ageing and UV resistance, making it ideal for applications that require long-term exposure to harsh environments. Silicone rubber is also biocompatible and non-toxic, making it the material of choice for the medical and food industries.

PVC tubing, on the other hand, is made from polyvinyl chloride, which offers good corrosion resistance and chemical stability. It can be used in temperatures ranging from 0°C to +60°C, making it suitable for fluid transfer and cable protection in ambient environments. pvc hose is a hard material with some mechanical strength, but is relatively inflexible.

Applications

Silicone rubber hose is widely used in aerospace, automotive industry, electronic appliances and medical devices. In the aerospace and automotive industries, silicone rubber tubing is used for the transmission of liquids and gases at high temperatures and pressures. In the electrical and electronic field, silicone rubber tubing is used as cable protection and seals to prevent high temperature damage to cables. In medical devices, silicone rubber tubing is used for infusion lines and seals due to its non-toxicity and biocompatibility.

PVC tubing is more commonly used in construction, agriculture and household appliances. In the construction industry, PVC pipes are commonly used for water supply and drainage systems and cable protection. In agriculture, PVC pipes are used to transport water and pesticides. In household appliances, PVC pipes are used as protective casings for wires and cables.

Safety Performance

Silicone rubber tubing has good flame retardant properties and low smoke and toxicity characteristics, which effectively protects personnel and equipment at high temperatures and under fire conditions. In contrast, PVC hose may release harmful gases at high temperatures, posing certain safety risks.

In summary, silicone rubber pipe and PVC pipe each have unique advantages and scope of application. When selecting pipes, the most suitable material should be chosen according to the specific application environment and requirements to ensure safety and functionality.
