What is the difference between medical grade silicone and medical silicone.baby pacifier clip wholesale

　　The medical-grade silicone that we usually say is a silicone that can be used medically, but it is limited to external use and cannot be used for the human body. However, it can be used in the medical industry, which can be in contact with the skin, but cannot reach the medical level and biocompatibility check. In other words, as long as it is not used in the body, this silicone is no problem.

　　Medical grade silicone parts show medical grade certification and biocompatibility report. It can be used for a range of medical purposes, including contact with human blood. The safety level is higher than the food level and medical level.

　　In addition to being elastic and flexible, the material is also almost entirely bioinert. That doesn't decay and break down in the human body. In addition, the cost of plastics and rubber elastomers has risen, and advances in chemical engineering have actually reduced the cost of silicone oil. In addition, many large medical silicone parts vendors provide a variety of special materials to meet the growing market demand, and these factors promote the development of medical silicone parts.

　　Medical grade silicone products are usually in the form of liquid silicone rubber (LSR) or high consistency rubber. Both can be used to form complex geometric shapes. The old HCR form is suitable for many conventional transfer and compression forming methods. LSR, on the other hand, is suitable for injection and processing similar to thermoplastics.

　　Liquid silicone rubber uses a two-part solution that requires heating in order to cure, but thermoplastics are a part of the resin that melts without heating and solidifies after cooling. The same basic process is very similar. Inject the raw fluid material into the mold under pressure, wait 1 minute, remove the finished part, and repeat.

　　In fact, the reason why medical grade silicone products are widely used in the medical field is mainly because of its own properties and structural characteristics, such as rubber plugs used for sealing packaging of medical agents require a certain degree of elasticity, and can still maintain the original tightness and air tightness after acupuncture, and the debris will not fall. However, the characteristics of silica gel itself are difficult to meet the current medical needs, and it is necessary to modify silica gel or add reagents to change its own shortcomings to meet its medical applications.

　　At present, the two materials widely used are silicone rubber and polyurethane, polyurethane has good biocompatibility, excellent mechanical properties, easy forming processing, controllable performance and other advantages, these two materials since ancient times in medicine has good biocompatibility and other advantages in any case, medical grade silicone can also be called medical silicone, but medical silicone can not be called medical silicone. If a very high level of safety is required, be sure to check whether a biocompatibility report or other medical grade report is available.
