Because of its chemical inertness and temperature resistance, liquid silicone rubber has a long storage time and service life.Silicone suppliers suggest that the raw material should be processed within six months, but in practice casting parts containing liquid silicone rubber can be stored indefinitely, although the moulder recommends three years.The durability of this medical material extends the service life of the corresponding medical device, benefiting both the manufacturer and the end user.

  Similarly, the medical device industry has shown a preference for liquid silicone rubber as a medical material.Unlike rubber, which some users are allergic to, liquid silicone rubber has a low sensitivity.Liquid silicone rubber does not contain phthalates in PVC, plasticizers that have been found in experiments to disrupt the endocrine system and damage the reproductive and nervous systems.

  However, cost is a drawback of liquid silicone rubber.Compared to other raw materials, such as thermoplastic elastomers and thermoplastic polyurethanes, silicone costs 3-5 times more;It takes twice as long to produce.

  In some applications where cost is a consideration, cheaper thermoplastic elastomer TPE and thermoplastic polyurethane TPU can be used if some of the properties of liquid silicone rubber such as temperature resistance, compression deformation and chemical inertia are not required.

  With the deepening of the medical device industry's understanding of the medical materials used in products, the unique performance of liquid silicone rubber makes its application scope expanded.As these properties become more widely known, new applications and expanding markets are driving the wider use of liquid silicone rubber in medical devices.

  Silicon is a common and readily available element on Earth.Liquid silicone rubber, on the other hand, is easy to make into complex shapes and chemically inert, which makes it ideal for use in medical devices from the outset.

  For medical use, silicone must be tested for biocompatibility and comply with FDA regulations.The application of medical silica gel can be divided into two categories: time-limited and time-free.Usually restricted for short-term transplantation and unrestricted for long-term transplantation.The liquid silicone rubber in this paper belongs to medical grade.

The biocompatibility and low sensitivity of liquid silicone rubber reduce the risk of allergic reaction to Z low during use.And because of its hygiene, bacteria and fungi are almost impossible to grow and spread.These properties make it an ideal material for both short - and long-term transplantation devices.

  Liquid silicone rubber is flexible, durable, transparent, can accept ULTRAVIOLET light and resist tension.Unlike traditional rubber, liquid silicone rubber can withstand extreme temperatures from -55℃ to 200℃ without denaturing.Because of this property, instruments made of liquid silicone rubber can be autoclaved for disinfection.

  Liquid silicone rubber also has an unusual capacity for permanent compression and can be made into different wall thicknesses in the same component.Combined with the material's durability and plasticity, these characteristics make it a key component of medical devices.

  In many synthetic rubber, silicone rubber is one of the best.It has tasteless non-toxic, not afraid of high temperature and withstand the characteristics of cold, in 300 degrees Celsius and minus 90 degrees Celsius "calm", "do not change color", still do not lose the original strength and elasticity.Silicone rubber also has good electrical insulation, oxygen resistance, light resistance, anti-aging and mildew resistance, chemical stability, etc.Because of these excellent properties, silicone rubber has widely played an important role in modern medicine.By the cooperation of hospitals, research institutes and factories, a variety of silicone rubber medical supplies have been successfully trial-produced.

  Silicone rubber anti-noise earplug: comfortable to wear, can block noise and protect eardrum.

  Silicone rubber fetal head suction device: easy to operate, safe to use, can be deformed according to the size of the fetal head, the fetal scalp will not be sucked up when attracting, can avoid scalp hematoma and intracranial injury and other diseases, can greatly reduce the pain of childbirth during dystocia pregnant women.

  Silicone rubber artificial blood vessel: with special physiological function, it can be "intimate" with the human body, and the human body does not reject it. After a certain period of time, it will be fully combined with the human tissue with excellent stability.

  Silicone rubber tympanic membrane repair piece: the piece is thin and soft, good finish and toughness.It is an ideal material for repairing eardrum, easy to operate and effective.

In addition, there are silicone rubber artificial trachea, artificial lung, artificial bone, silicone rubber duodenal tube, etc., the effect is very ideal.
