Universal silicone profiles
These are the most common types.
Approved by the US Food and Drug Administration, they can be colored into various colors. They have good performance under typical conditions and are suitable for general sealing and insulation applications in fields such as household appliances and basic machinery. For example, they may be used as door seals for refrigerators to keep cold air in.

High temperature silicone profiles
These profiles are designed to withstand extreme high temperatures and can operate at temperatures up to 300 ° C. They are an ideal choice for applications that are often exposed to high temperatures in ovens, industrial furnaces, and automotive engines. In the oven, high-temperature silicone profiles can be used as door gaskets to prevent heat leakage. ​


Platinum cured silicone profile
Platinum cured silicone profiles have excellent biocompatibility and have been approved by the US Food and Drug Administration and the US Pharmacopeia Level VI. This makes them very suitable for medical and pharmaceutical applications. Due to their high tear strength and transparency, they are used in projects such as peristaltic pumps in medical equipment and food processing machinery.

Flame retardant silicone profile
These configuration files comply with standards such as EN 45545 and are crucial in applications where fire safety is of concern. They are used to construct public transportation vehicles such as trains and buses, as well as some electrical enclosures. In train carriages, flame-retardant silicone profiles can be used around doors and windows to prevent the spread of fire. ​


In short, the diversity of silicone rubber profiles makes them widely used in countless industries, with each type tailored to specific environmental and functional requirements.
