The difference between domestic silicone tube and imported silicone tube
Imported silicone tubes are made of imported raw materials, such as Dow Corning, Japan, and Shin-Etsu Japan. The products have passed ROHS and FDA international environmental protection grade professional tests. They have excellent high-temperature resistance to yellowing. After vulcanization, the transparency of the product is close to full transparency. It is tasteless after one-time extrusion and vulcanization. No need for secondary vulcanization, it can completely replace platinum vulcanizing agent, and there is no blooming. It is suitable for the extrusion of high-quality silicon products such as fully transparent or colored silicone tubes, sheets, and strips. The products are resistant to light in long-term use. Aging or yellowing due to ultraviolet light, heat, water, etc. Special note: It can be used for precipitation rubber and high-strength gas-phase silicon rubber to extrude hot air vulcanization without generating bubbles.
The performance of the domestic silicone tube is slightly worse than that of the imported one, the tensile strength is lower, and the color is not as bright as the domestic imported silicone strip.The same hardness, the imported silicone tube is more elastic.
　　 Appearance color-translucent (domestic silicone tube), high transparency (domestic imported silicone tube)
　　 taste-slightly odor (domestic silicone tube), odorless (domestic imported silicone tube)
　　 tear resistance-become milky white after being stressed (domestic silicone tube)
　　 does not change color after being stressed (domestic imported silicone tube)
Advantages of domestic silicone tube:
　　1. Resistance to weak acids and alkalis; resistance to ozone; resistance to high temperatures; widely used as accessories for medical supplies and food supplies;
　　2. Translucent, good elasticity, strong pull resistance; good extrusion resistance (but not for peristaltic pumps);
　　3. Wide temperature range: about -30～180℃; medium pressure capacity: 2-3 kg
Advantages of imported silicone tube:
　　1. Resistance to weak acids and alkalis; resistance to ozone; resistance to high temperatures; widely used as accessories for medical supplies and food supplies;
　　 2. Close to full transparency, easy to observe; better elasticity, stronger pull resistance; better resistance to extrusion (the peristaltic pump must use an imported tube);
3. Wider temperature resistance range: about -30～250℃; medium pressure resistance: 2-3 kg
Silicone tube has excellent electrical insulation performance, aging resistance, chemical stability, oxidation resistance, weather resistance, radiation resistance, physiological inertness, good air permeability, high and low temperature resistance, and can be used for a long time at -60℃～200℃. Toxic and tasteless, it is widely used in medicine and can be widely used in aviation, electronics, petroleum, chemical, machinery, electrical appliances, medical, oven, food, etc.
