PMQ/VMQ Silicone Rubber

Silicone rubber, PMQ / VMQ, is a synthetic polymer with many uses and beneficial properties. This material type is based on silicon (Si), oxygen (O), silicon (silica) and hydrocarbons, creating a unique composition that makes it useful across various industries and applications.

Silicone rubber is produced through the polymerization of silicone-based compounds. Its most notable properties include temperature resistance, chemical resistance and electrical insulation. Silicone rubber is also a common alternative in the food industry because it does not release any harmful substances when in contact with food.

Silicone materials are often divided into three different groups based on vulcanization. These are heat-cured solid rubber, heat-cured liquid rubber (LSR) and room-temperature vulcanized rubber (RTV).

Despite its many advantages, silicone rubber has some limitations. Silicone rubber has limited resistance to aromatic oils and polar organic solvents. It also has poor electrical properties and is not very flame-resistant.

Silicone rubber combines oil resistance and chemical resistance with an ability to handle high temperatures and ozone exposure. It is often used in applications where prolonged exposure to heat, chemicals and other extreme conditions is required.

Products in PMQ / VMQ - Silicone Rubber

Silicone rubber is partly inorganic and partly organic in nature, which gives it a unique place among synthetic rubber materials. It is used in a wide variety of industries due to its versatile properties and resistance to extreme conditions. Some of the most common industries include healthcare, the automotive industry, and the food industry.

Below are some of the products manufactured from silicone rubber:

Implant: Silicone rubber is used in medical implants, among other applications, due to its biocompatibility and ability to withstand sterilization and chemical disinfectants.

Seals: Silicone rubber is commonly found in automotive applications in the form of seals. It is a good alternative when high temperature resistance and resistance to oils and chemicals are needed.

Sports equipment: Silicone rubber is used in sports equipment such as swimming goggles and diving gear due to its waterproof and elastic properties.

Kitchen utensils: Silicone rubber is used in many of the utensils used in. Its high heat resistance and food safety make it a good choice for pot lids, baking pans and many other kitchen utensils.

Protection and insulation: Silicone rubber is used to protect and insulate electronic components and devices from moisture, dust and chemicals.

These are some examples of products and uses for silicone rubber.
