Temperature-resistant, UV-resistant, durable - simply silicone.
Silicone - a wondrous material
Silicone is a material that is used everywhere today. It is often mistakenly referred to as “rubber”. Although some silicone products are similar in their properties to natural rubber, there are some significant differences. A special property of silicone is its resistance. This makes it so versatile and popular.

What is silicone?
Simply put, silicone is a special mixture of rubber and finely ground quartz sand. This is where its name comes from. Quartz sand is chemically “silicon” and has a wide field of application. Among other things, it is the main component of modern semiconductor technology. Silicone was first produced in the 1920s. Industrial production only began in the 1940s. Since then, it has gained increasing importance.
Silicone compounds and their properties
Most users understand silicone to be the practical pastes that harden into a rubber-like substance. In fact, there isn’t just one silicone product, but three.
- Liquid Silicone
- Silicone Rubber
- Silicone Resin
Liquid silicone has very good lubricating properties. It is also suitable as hydraulic fluid or even as massage oil.
Silicone rubber is a widespread basic material for many rubber-like products. These are not only seals or tensioning straps. Cake molds, ice cube trays, printer rollers, door rubbers, or negative molds for plaster and cement casting are also made from it. Even tin figures can be produced in divisible hollow molds made of silicone. This shows its essential difference from rubber: silicone is more temperature-resistant and more durable than rubber obtained from natural rubber.
Silicone resin is of great importance in the chemical industry. It helps to produce other complex products.
Special advantages of silicone
Silicone offers the following advantages:
- flexible
- tear-resistant
- infinitely moldable
- adaptable to many applications
- suitable for hygienic applications
- temperature and UV resistant
- electrically insulating
- water and gas tight
- unproblematic in disposal
- Temperature resistant
Silicone is very versatile. Any shapes can be produced, especially from silicone rubber. Silicone products are always soft and flexible. However, they remain tough, temperature-resistant, and resistant to UV rays or chemicals. Silicone compounds can be prepared in such a way that they are safe for food or for hygienic applications. The hoses and masks of CPAP devices (sleep apnea) are therefore made of this material as standard. Since silicone is not completely organic, it does not mold or rot. Despite its robustness and durability, silicone is considered sustainable. When disposed of, it decomposes very slowly. However, it remains completely non-toxic throughout the entire decomposition process. In the end, only water, carbon dioxide, and quartz flour remain.
Producing silicone
The production of silicone is a demanding task. Silicone manufacturers must use efficient and environmentally friendly processes to be marketable. In addition, this material can be precisely adjusted to customer requirements. This begins with coloring and ends with the implementation of certain technical properties. Even electrically conductive silicone can already be produced. The exact adjustment of every property of the silicone products according to customer requirements is therefore the biggest challenge for a manufacturer. This makes the production of silicone compounds a matter of trust. Therefore, come to us. In addition to a large selection of standard silicones, you will also find individual solutions for your specific challenges.
