How Much Do You Know About Medical Silicone Rubber Products?

The main material of medical silicone is silicone rubber, which belongs to one of the synthetic rubbers. Its chemical name is poly methyl vinyl siloxane, which is polymerized by dimethyl silicone monomer and other organic silicone monomers under the action of acid or alkaline catalysts, with a relative molecular weight generally between 400,000 and 500,000. Silicone rubber products have excellent medical properties. They are colorless, non-toxic, high-temperature resistant, oxidation-resistant, soft, transparent, and other characteristics. They can solve medical problems and meet the medical needs of patients.


Medical silicone rubber products are widely used bio-materials in the medical device market


There are various forms, such as liquid silicone, foam silicone sponge, and elastic solid silicone rubber. At present, solid silicone rubber is widely used. Silicone rubber has good biological compatibility, no irritation, no toxicity, no allergic reactions, and minimal rejection reactions from the body. It has good physicochemical properties and can maintain its original elasticity and softness when in contact with body fluids and tissues, and is a relatively stable inert substance. It is heat-resistant and can be sterilized. It is easy to process and shape, and easy to use.

Applications of medical silicone rubber products


Solid medical silicone rubber products can replace bones or cartilage as tissue filling or support materials, and can be used to manufacture artificial joints and tendons to repair limb joint and tendon defects. They are widely used as restorative materials in facial, ear, nose and other deformity defects.


Foam medical silicone rubber can replace human adipose tissue to repair facial subcutaneous tissue defects and deformities, such as hemifacial atrophy.


Thin film medical silicone rubber products can be used as substitutes for tendon sheaths; external intestinal fistula occlusion chips are also made of this type of silicone rubber, which is used to block intestinal fistulas from leaking, maintain intestinal patency, and restore intestinal nutrition, reducing complications and simplifying the treatment of intestinal fistulas.


Liquid medical silicone rubber products, also known as silicone oil, are a low-viscosity, transparent liquid. They are injected into concave deformities in the craniofacial region using coarse injection needles. They are easy to use, can be shaped, do not require hospitalization, and can be treated on an outpatient basis. In addition, medical silicone rubber is used to make brain shunt devices for the treatment of hydrocephalus, as well as spherical artificial heart valve leaflets to replace damaged mitral valve leaflets. Silicone contraceptive rings have more advantages such as safety, convenience, reliability, and long-lasting effect. Silicone vascular catheters, gastric tubes, and urinary catheters have less trauma, less irritation, and can be left in the human body for a long time. They have been widely used in clinical practice.
