یکی از ویژگی‌های بارز این مات‌ها، قابلیت تنفس آن‌هاست. به این معنی که آب و هوا به راحتی از آن‌ها عبور می‌کند و در نتیجه شما احساس گرما و ناراحتی نمی‌کنید. این ویژگی به ویژه در روزهای گرم تابستان بسیار حائز اهمیت است. همچنین، برخی از مات‌ها دارای خاصیت ضدآب هستند و به همین دلیل شما می‌توانید با خیال راحت در کنار آب استراحت کنید.

To ensure correct fit and proper protection against contaminants, the inside diameter of an oil seal must be slightly smaller than the shaft diameter.
Operating temperatures for engine oil seals (see Fig. 14.11 and cross-section of lip seal with garter spring in Fig. 14.22) vary widely, depending on engine design and location within the engine. Typically, the rear crankshaft seal is subjected to much higher temperatures than the front seal. Oil sump temperatures vary considerably, depending on provisions for oil cooling. This allows use of hydrogenated nitrile (HNBR), silicone, or acrylic elastomers for some seals in relatively low-temperature environments (120–140°C or 250–284°F). Standard fluoroelastomers (FKM), bisphenol-cured VDF/HFP/TFE terpolymers with 68–69% fluorine content, perform well in oil service up to about 160°C (320°F). More resistant fluoroelastomers are necessary for reliable long-term performance in more severe environments.
If you are looking for the highest temperature resistant oil seals, Perfluoelastomer can go up to 600°F. If you are more concerned for low temperature, Chloroprene can go all the way down to 40°F, which is why it is used most commonly for refrigeration. And if FDA applications or medical devices are your primary concern, Butyl , the all petroleum compound, will be your best choice. As you can see, when choosing the right material to work with, you must analyze several other key components to help choose the right one.
In conclusion, auto gaskets, auto head gaskets, and automotive gaskets are essential components in vehicle systems, contributing to the efficiency, performance, and reliability of automotive systems. Understanding the significance of these gaskets and their proper maintenance and replacement is crucial for optimizing the performance and longevity of the vehicle.
