The difference of food grade silicone tube and silicone hose?
![]()
Food grade silicone hose and medical silica gel tube is on the safety and health of relatively strict, at the time of consultation some customers will ask what is the difference between a food grade silicone tube and silicone hose? Below small make up on the details of the differences and similarities between them.
First of all, to compare the difference between them between the concept of.
Food grade silicone tube is made of imported rubber raw materials, the use of scientific production technology, production of raw rubber by batch method, according to the gas phase adhesive with high tear resistance and high transparency, mix of super high and lower the hardness, functional mix the characteristics of production of the silicone tube, this product is more extensive adaptability. Compared with the traditional dual two four vulcanization process of silicone rubber hose and silica gel profile, which has high transparency, tasteless, the same yellow, do not spray cream etc., especially to solve the problem of black hose spraying cream products, blue fade.
Medical silica gel tube adopt raw materials imported silicone rubber, minimum diameter can reach 0.4 mm, the biological compatibility testing, to human tissue reaction is very small, not value into human tissue caused by foreign body reaction, on the surrounding tissue without inflammation, the tube can be placed in the body 20 days no abnormal reaction. The peristaltic pump special silicone tube lifetime can be over 175 hours of continuous use. So get more and more extensive application in the medical and health aspects.
Secondly, the difference between their characteristics comparison.
The characteristics of food grade silicone rubber hose:
1, food grade silicone belongs to an environment-friendly silicon silica a, non-toxic, no odor, high transparency;
2, soft, good elasticity, resistance to kinking deformation;
3, no cracking, long service life, cold resistance and high temperature;
4, has a higher tear strength and superior electrical performance;
5, ordinary temperature yellowing, non blooming, do not spit white, do not fade, long home water has no scale, no peculiar smell;
Characteristics of medical silicone rubber tube:
1 medical silica gel tube, cold resistance and high temperature resistance, weak acid, harmless non-toxic tasteless;
2 high transparency, high elasticity, high resistance to ultraviolet radiation;
3 characteristics of good elasticity, resistance to kink not deformation, soft, arc resistance, corona resistance, chemical stability, physiological inert, non-toxic to human body without stimulation, hydrophobic, breathable, excellent resilience, permanent deformation, can be in -50 degrees to 250 degrees, the special requirements of up to degree, excellent insulation in ethylene oxide sterilization, can be used under high temperature conditions.
4 comply with food and drug testing standards, ordinary temperature constant, do not spray cream yellow, do not spit white, do not fade, long set in the water without scale.
In short, most of the characteristics of food grade silicone rubber hose and medical silicon rubber hose are the same. The above is the similarities and differences between them, and they hope to help everyone.
