3. Thermal Insulated Access Panels In environments where temperature control is vital, such as in vaulted ceilings or air-conditioned spaces, insulated panels help maintain energy efficiency. They prevent thermal loss, ensuring that the temperature remains stable within buildings.

Seals, including oil seals, have undergone a great development in recent years and are totally unlike the original product. PTFE has taken over the oil seals market for modern engines mainly because traditional oil seals started causing more and more problems. Such as evaporation of chemical plasticisers from the elastomeric material, which eventually caused engine oil leakage. Now, the focus is more on durability and frequency of servicing.



The metal used in the outer case of oil seals is usually made of carbon steel. Upon request, and depending on quantities, a different type of steel (such as stainless steel) can be used.
-50 °C to + 150 °C


Most oil seals consist of some basic elements that configure their structure, such as the sealing element, the metal case, and the spring:
Oil seals are made from multiple compounds and materials. Some of the oldest, still in use today, are leather and felt compounds. The trend in mass production, however, has seen a move towards synthetic rubber or elastomers. Nitrile is by far the most popular material but developments in PTFE have created a surge of interest in buyers needing seals for high-speed shaft rotation applications. Viton is taking over from the polyacrylic and silicone, as it works better in high-temperature applications and has a high-resistance to abrasion and harmful chemicals.
The quality of the rubber or rubber fabric used to make an outer case is the same as the quality of the rubber sealing lip. Fabric reinforced rubber is, as the name suggests, rubber reinforced with a fabric.
