polysiloksany

Polysiloksany, often referred to as silicones, are polymers with a repeating silicon-oxygen backbone. This unique inorganic backbone is characterized by alternating silicon and oxygen atoms (Si-O-Si-O). Attached to each silicon atom are organic side groups, which can vary widely. The nature of these side groups significantly influences the physical and chemical properties of the resulting polysiloxane.

The Si-O bond is strong and flexible, contributing to the thermal stability and elasticity of polysiloxanes. This flexibility allows them to withstand wide temperature ranges, from very low to very high. They also exhibit excellent resistance to weathering, ozone, and UV radiation, making them suitable for outdoor applications. Polysiloksany are generally hydrophobic and have low surface tension, which contributes to their water-repellent properties and ease of spreading.

These versatile polymers find application in a multitude of industries. In construction, they are used as sealants and adhesives due to their durability and weather resistance. The medical field utilizes them for implants, tubing, and prosthetics because of their biocompatibility and inertness. In the personal care industry, polysiloksany are common ingredients in shampoos, conditioners, and cosmetics, providing a smooth feel and improving product texture. They are also employed in the automotive sector for lubricants and coatings, and in electronics as insulating materials. The broad range of possible side groups allows for tailored properties, making polysiloksany a highly adaptable class of materials.
