What is the role of silicone rubber

Author:admin Time:2017-08-05 15:52:00
In a large number of synthetic rubber, silicone rubber is the best in the world. It is odorless and non-toxic, and high temperature and resist cold characteristics, at three hundred degrees Celsius and ninety degrees Celsius when "it" and "natural", still without losing the original strength and flexibility. Silicone rubber also has excellent electrical insulation, oxygen resistance, aging resistance, anti - aging, anti - mildew resistance, chemical stability, etc. Because of these excellent functions, silicone rubber has played an important role in modern medicine. In recent years, the cooperation of hospitals, scientific research units and factories, silicone rubber products trial production of a variety of silicone rubber medical supplies.
Noise prevention earplugs: comfortable wearing, excellent isolation of noise, and maintenance of the eardrum.
Rubber tyre head: simple operation, to the use of safety, according to the size of the fetal head deformation, to fetal scalp will not be sucked, defects can prevent scalp hematoma and intracranial lesions, can greatly reduce the labor pain childbirth pregnant mother.
Silicone rubber artificial blood vessel has special physiological function, it can be intimacy with human body, and human body does not exclude it. After a certain time, it will be perfectly integrated with human body arrangement, and the stability is excellent.
Silicone rubber tympanic membrane patch: it's thin and soft, excellent in smoothness and patience. Is to repair the eardrum and ambition data, simple operation, good effect.
In addition, there are silicone rubber artificial trachea, artificial lung, artificial bone, silicone rubber duodenal tube, and so on, the efficacy is very ambitious.
Silicone rubber has excellent heat resistance, cold resistance, dielectric resistance, ozone resistance and weathering resistance. The outstanding function of silicone rubber is to use the temperature widely, and it can be used for a long time at -60 C (or lower temperature) to +250 C (or higher temperature). But the tensile strength and tear strength of silicone rubber mechanical function is poor, at room temperature, its physical mechanical function than most synthetic rubber, and in addition to silicone, fluorosilicone rubber, silicone rubber, oil resistance, solvent resistance usually function unsatisfactory, so the silicon rubber is not suitable for the general conditions of the occasion, but very suitable for many special occasions.
It is worth mentioning that in biomedical engineering, polymer materials have a very important effect, and the silicone rubber is a kind of important medical polymer materials. It has excellent physiological lazy, tasteless, no corrosion, anti coagulation, and the good compatibility, can have strict disinfection. Pipes, sheets, thin films, and special-shaped components can be processed according to the needs, which can be used as medical instruments, artificial organs and so on. Nowadays, there are specialized medical grade silicone rubber at home and abroad.
