ceiling mineral fiber
Wall angles, which are installed along the perimeter of the room, typically measure 1/2 inch to 1 inch in leg height and are designed to hold the edges of the ceiling tiles securely. This component ensures stability, providing a solid framework for the entire ceiling grid.
1. Moisture Resistance One of the standout features of PVC gypsum is its excellent moisture resistance. Traditional gypsum boards are susceptible to water damage, which can lead to mold and structural integrity compromises. PVC gypsum mitigates this risk, making it an ideal choice for high-moisture areas like kitchens and bathrooms.
One of the defining features of mineral wool insulation is its non-combustibility. The boards are classified as non-combustible materials, meaning they can withstand high temperatures without igniting. This property is particularly beneficial for fire safety in buildings, contributing to passive fire protection strategies by slowing down the spread of flames and smoke.

Leather is probably the oldest of the lip materials still in common use, but the move towards mass production methods has seen a massive increase in the development of synthetic rubbers which lend themselves to accurate and repeatable injection and compression moulding. Nitrile (NBR) is still by far the most common elastomer for “normal” use, whilst Viton® (FKM/FPM) is rapidly replacing Polyacrylate (ACM) and Silicone (VMQ) for high-temperature applications. Viton® also has high resistance to abrasion and chemical attack making it a preferred elastomer. Recent developments in the use of PTFE for Rotary shaft seals has caused widespread interest particularly for high-speed shaft rotation or poor lubrication applications.
Leather oil seals have great running properties and are mostly used for abrasive applications.
Oil seals come in various shapes to fit the machine or substance for sealing.
For this reason, when designing a machine, it is important to select the oil seal that is right for that machine.
Next time, we will explain the key points to consider when selecting your oil seal.
