1. Material Choice The type of material used for the strip seals is a significant determinant of cost. Rubber seals tend to be more durable and effective at providing insulation compared to vinyl seals, which may be less expensive but also less effective over time.

3. V-Seals These seals are shaped like a 'V' and are often used to seal the gaps between two surfaces. They are great for vertically sliding windows and doors.

3. Market Access CE certification opens doors to markets across the European Economic Area. For manufacturers, this means enhanced competitiveness and the ability to reach a broader customer base. The CE mark acts as a signal to potential buyers that the product adheres to high standards, making it a preferred choice for contractors and builders.
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.
