Precautions to use the brake system of a car
Silicone hose is a kind of special comprehensive performance of rubber, with excellent electrical insulation performance, aging resistance, chemical stability, anti-oxidation weather resistance, radiation resistance, physiological inertia, good air permeability, high and low temperature resistance, can be used at -60℃ ~ 250℃ for a long time. Therefore, it is widely used in aviation, electronics, petroleum, chemical industry, machinery, electrical appliances, medical, oven, food and other modern industry, national defense industry and daily necessities.
Silicone vaccum hose is widely used, so its classification is so much. Generally, there are medical grade silicone vacuum hose, food grade silicone vacuum hose, industrial silicone hose, silicone special-shaped hose, etc.. Today we’re going to talk about food grade silicone vacuum hose and medical grade silicone vacuum hose.
Q: As for food grade silicone hose and medical grade silicone hose, why do we need to provide relevant medical and food testing certificates?
A: Both of them are used for health, safety and human contact, so the production and use requirements are very strict! So what’s the difference between them?
Concepts:
Food grade silicone vacuum hose
Using imported silicone raw materials, scientific production process, the intermittent method to produce raw rubber. According to the characteristics of gas phase rubber high tear resistance and high transparency, mixing high and lower hardness, functional mixing rubber production silicone tube, this product has a wide range of adaptability.
Compared with the traditional silicone tube, it has the advantages of high transparency, odorless, unchanged yellow, no frost spraying, etc., especially to solve the problem of black rubber tube frost spraying and blue products fading.
Medical grade silicone vacuum hose
All imported silicone rubber raw materials, the minimum inner diameter can be up to 0.4 mm, through the biocompatibility test, the response to human tissues is very small, value into human tissues will not cause foreign body reaction, no inflammation to the surrounding tissues, the tube can be placed in the human body for 20 days without abnormal response. Peristaltic pump special silicone tube life can be used for more than 175 hours.
Features:
Food grade silicone vacuum hose
1) Food grade silica gel is a kind of environmentally friendly silica gel with non-toxic smell and high transparency;
2) Soft, elastic, kink resistant and not deformed;
3) No cracking, long service life, cold and high temperature resistance;
4) With higher tear resistance and superior electrical performance;
5) Keep yellow at room temperature, do not spray frost, do not spit white, do not fade, long standing water no scale, no peculiar smell.
Medical grade silicone vacuum hose
1) Medical silicone gel tube is cold and high temperature resistant, weak acid and alkali resistant, harmless, non-toxic and tasteless;
2) High transparency, high elasticity, strong uv resistance;
3) kink deformation resistance, softness, arc resistance, corona resistance, chemical stability, physical inertia, non-toxic no stimulation to the human body, hydrophobic, breathable, have good resilience, deformation time is long, etc, can be used in – 50 degrees to 250 degrees, the special requirements of degree, excellent insulation, usable ethylene oxide sterilization under high temperature condition;
4) In line with the food and drug testing standards, it should be kept at room temperature without yellowing, frost spraying, white spitting and fading, and it should be kept in water for a long time without scale.
In a word, most of the characteristics of food grade silicone vacuum hose and medical grade silicone vacuum hose are the same.
These are the similarities and differences between them, hope to help you.
