Characteristics of Linen Phenolic (L)

Linen Phenolic (L) is known for its fine weave fabric base, which gives it a smoother finish compared to canvas phenolic.

 

This results in superior machinability, making it ideal for applications requiring precision and detail. It also offers good mechanical strength, combined with moderate wear resistance, which allows it to perform reliably in components subjected to friction.

 

Linen phenolic is dimensionally stable and maintains tight tolerances, essential for applications demanding accuracy. It can also withstand temperatures up to 250°F (121°C), and its relatively low moisture absorption contributes to its durability in humid environments.

 

How Linen Phenolic is Used:

Explore how this composite material is used across industries:

 

Fine Machined Parts: Its smooth finish and high machinability make it excellent for crafting precision components like small gears and bushings.

 

Threaded Parts: Linen phenolic’s fine fabric structure allows for detailed threading, ideal for parts where precise threads are needed.

 

Bearings: Its moderate wear resistance and smooth surface are perfect

for creating bearings that operate under moderate loads and speeds.

 

Electrical Insulators: While not as insulating as electrical-grade

phenolic, it is still commonly used in non-critical electrical insulation applications.

 

Small Gears and Cams: The fine structure of linen phenolic allows for intricate machining, making it suitable for small mechanical components.
