Silicone Rubber Additive

Silicone rubber is a unique, synthetic polymer that can be used to make a wide variety of useful products.silicone rubber additive While it is more expensive than many other types of rubber, it is highly durable and has a high resistance to UV degradation. Many different additives can be added to silicone rubber to alter its properties or give it special functions. Some of these additives can be added during mixing, while others are applied directly to the finished product.

One of the most important aspects of silicone rubber is its ability to withstand extremely high temperatures, which makes it a popular choice for applications in hot or cold environments.silicone rubber additive This property also allows silicone rubber to be molded into various shapes and sizes, which are then used in applications such as medical devices or automotive components.

Unlike most plastics, silicone does not melt at high temperatures.silicone rubber additive It will lose its mechanical properties, however, and become brittle at around 400oC. Silicone rubber can be modified with additives to increase or decrease its autoignition temperature, as well as to improve its tensile and tear strength.

Another important trait of silicone rubber is its ability to resist chemical attack and abrasion.silicone rubber additive It is resistant to chemicals such as acids and solvents, making it a common material for electrical insulation and medical device coatings. It can also be formulated to meet a variety of specific requirements such as steam resistance, metal detectability, extreme high or low temperature resistance and flame retardancy.

Most silicones are colorless, but they can be pigmented using a variety of materials and methods. Some pigments can add a slight sheen to the surface, while others can make the silicone appear more matte. Some can even change the way the silicone feels to create a softer or more “flesh-like” feel, which is particularly helpful in making silicone props that are designed to mimic human skin.

The properties of silicone rubber can be further improved with the addition of additives that are designed to enhance its optical qualities. For example, optical brighteners can be added to silicone rubber to make it look more white. These are small particles that scatter light and give the material a more appealing appearance.

Other additives can be used to modify the physical properties of silicone rubber, such as modifying its elasticity or hardness level. These additives are usually mixed with the base material in a proportion that is dependent on the desired result. The type of additive needed for a particular application can be determined by consulting the product data sheet or speaking with a WACKER CHEMIE customer service representative.

Additives that can be added to silicone rubber include silicone thinners, thickeners, cure accelerators and curing agents. They are added to the base material (part A) in varying proportions depending on the desired effect. Silicone thinners reduce the viscosity of the mixture so it can be brushed or spattered onto surfaces. Thickeners turn a pourable silicone into a thixotropic spatterable mass and cure accelerators speed up the vulcanization process.
