Biocompatibility of Liquid Silicone Rubber (LSR): Part II

In the United States, the Food and Drug Administration (FDA) is the entity in charge of approving materials that come into contact with human body, based on the material’s biocompatibility and biostability properties. There are a variety of methods that can be used to verify a material’s properties. However not all materials will require testing, the FDA states “if there is sufficient knowledge about the biocompatibility and toxicity of the material, then it is not necessary for further biocompatibility testing”.

Misconceptions about Liquid Silicone Rubber (LSR)

The silicone family is made up of an enormous variety of compounds, and is perhaps the most widely used family of materials in the world. Liquid Silicone Rubber materials can be found in consumer products in applications such as appliances and electronics, in astronomy, biotechnology, and in the automotive, aviation, beverage, construction, paint, plumbing, textile, and toy industries.

How Is Silicone Produced?

Silicone is a versatile polymer used in elastomers, oils, greases and caulks, among other materials. Its primary ingredient is silica — one of the most commonly occurring forms of sand. Here’s what you need to know about silicone production.

Types of Liquid Silicone Rubber

Silicone rubbers are man-made polymer materials that have a wide range of industrial and manufacturing applications. The various types of silicone rubbers include room temperature vulcanize, liquid silicone, fluorosilicone and high-consistency rubber. In this post, we’ll provide information about liquid silicone rubber, including what it is and the types that are available for manufacturing purposes.

Liquid Silicone Rubber and Electricity

Colored telecommunications cables and wires

Ceramic and glass have long functioned as the material of choice for medium and high-voltage electrical applications, high-voltage insulators and lightning arresters. These materials have good resistance to electrical stress as well as outdoor exposure without suffering significantly from deterioration. The transmission/distribution industry and international standard bodies have thoroughly discussed the advantages and disadvantages of these materials. Their shortcomings include contamination and the inability to handle certain stresses. These concerns have led to significant innovations in material science, especially as it relates to insulative materials and silicone rubber’s electrical conductivity.
