The glass is melted at high temperatures and formed into sheets or other shapes. After cooling, it is often treated to enhance its surface durability and resistance to scratching. Additional processes, such as lamination or coating, may also be employed to improve performance and strength, making ultra clear glass suitable for a variety of environments.
The difference between crystal and glass
Waterproof rubber gaskets are designed to provide a secure and watertight seal, making them ideal for applications where protection against moisture and environmental elements is essential. These gaskets are commonly used in outdoor equipment, marine applications, and electrical enclosures to prevent water ingress and ensure the integrity of the sealed components. The waterproof properties of rubber gaskets contribute to the reliability and longevity of the sealed systems.
Today, traditional oil seals have to compete with a new variant oil seal, which is used in most modern engines.
These are comparable to type R and RST, except the outer case does not have a metal reinforcement ring. To compensate, the outside is not made of normal rubber, but a hard, heavy-duty rubber fabric. The advantage is that these types can be made in a split version. They are almost always produced to order, and made of NBR or FKM.
