How many quality standards for PVC gas hose do you know
The difference between silicone hose and PVC hose
First of all, silicone is a rubber material and PVC is a plastic material. The main material of PVC pipe is polyvinyl chloride, and the main material of silicone pipe is silicon dioxide.
PVC hose is made of polyvinyl chloride resin with stabilizer, lubricant, etc. and extruded with a hot-press injection molding machine. Its main properties and electrical insulation properties are good; it has good chemical stability; it can be self-extinguished; low water absorption; easy to bond , The highest temperature resistance is about 40 °. The main appliances are industrial gas, liquid transportation, etc., domestic sewer pipes, water pipes and so on.
Silicone hose, silicone material has stable chemical properties. Except strong alkali and hydrofluoric acid, it does not chemically react with any chemical substances. It has good chemical properties, good electrical insulation properties, is not easy to age and weather resistance, and the material is up to 330 degrees to- Around 40 degrees, environmentally friendly non-toxic material, colorless and odorless, mainly use household products.
1. Different temperature:
PVC hoses are only suitable for water supply systems where the temperature does not exceed 45 ° C.
Silicone hose continuous use temperature range: -60 ℃ ～ 200 ℃;
2. Product uses are different:
PVC hoses are used in many industries such as building materials, packaging, and medicine. Among them, the building materials industry accounts for the largest proportion, 60%, followed by the packaging industry, and several other small-scale applications.
Silicone hoses are widely used in aviation, electronics, petroleum, chemical, machinery, electrical, medical, oven, food and other industrial sectors as good electrical insulation seals and liquid transport materials. Precision representatives, oil pipelines, household appliance seals, drinking water pipeline seals, medicine, etc.
3. Is there a smell?
Silicone hose is a material that is harmless, non-toxic and tasteless.
There are some odors in the PVC hose manufacturing process using some additives.
