What is the difference between GPO-3 gpo 3 material vs. GPO-1, GPO-2

GPO-3, GPO-1 and GPO-2 are all polyester glass fiber reinforced insulation materials, but there are some differences between them, mainly related to heat resistance, mechanical properties and flame retardancy. Here are the main differences between them:

 

1. Differences in matrix:

GPO-1: GPO-1 is a pure polyester material without glass fiber reinforcement. It has relatively low mechanical properties and is mainly used for low-demand insulation applications.

GPO-2: GPO-2 is a polyester material containing moderate glass fiber reinforcement, which improves some mechanical strength and is suitable for some moderately demanding electrical and mechanical applications.

GPO-3:  GPO-3 is a polyester material reinforced with a high proportion of glass fiber. It has high mechanical strength and heat resistance and is suitable for electrical applications with high performance requirements.

2. Heat resistance:

GPO-1: Has lower heat resistance and is generally suitable for low temperature environments.

GPO-2: Has moderate heat resistance and can work stably in a moderate temperature range.

GPO-3: Has relatively good heat resistance and can maintain stability in moderate temperature ranges.

3. Mechanical properties:

GPO-1: Relatively low mechanical strength.

GPO-2: Mechanical strength is between GPO-1 and GPO-3.

GPO-3: Has high mechanical strength and rigidity.

4. Flame retardancy:

GPO-1: Generally has poor flame retardant properties.

GPO-2: There is a certain improvement in flame retardant performance.

GPO-3: Generally has better flame retardant properties, helping to improve the safety of materials in fire situations.

 

5. Color:

GPO-1: Usually black.

GPO-2: Usually gray.

GPO-3: Usually orange or red to aid in visual distinction and identification.

In fact, GPO-3 will be superior to GPO-1 and GPO-2 in all aspects of performance and features. Of course the price will be slightly higher. If you want to buy GPO-3 with good quality and affordable price, it is best to choose to buy directly from the insulation material manufacturing factory to reduce the price difference made by middlemen.
