Why Choose PA66 GF25 or PA66 GF30 Glass Fiber for Engine Cover？

What Are PA66 GF25 & PA66 GF30?

PA66 GF25 and PA66 GF30 are special plastics. They are made with nylon and glass. PA66 GF25 has 25% glass. PA66 GF30 has 30% glass.

The glass makes these plastics strong. It helps them not melt when hot. This is why car makers like them for engine covers.

Why Use These Materials for Engine Covers?

Engine covers need to be:

• Strong
• Heat-safe
• Light
• Long-lasting

PA66 with glass fiber meets all these needs! Let's see why they are so good.

Top 5 Reasons to Pick PA66 GF25/GF30

1. They Can Take the Heat!

Engines get very hot. PA66 GF25 can handle heat up to 200°C. PA66 GF30 is even better - it works up to 220°C!

This means your engine cover will not melt or warp.

2. They Are Light but Strong

These materials are 30% lighter than steel. But they are still very strong! This helps cars use less gas.

3. They Fight Off Chemicals

Engine parts touch oil and gas all the time. PA66 GF25 and GF30 do not break down when this happens. They stay strong!

4. They Cut Down Noise

The glass in these plastics helps stop vibrations. This makes your car more quiet.

5. They Keep Their Shape

When it's hot, then cold, then hot again, these materials don't change shape much. This is called dimensional stability.
