What is the difference between G-10 and g11 material?


As a plastic supplier, it’s important to understand the differences between various materials to meet the specific needs of our customers. One common question that arises is about the dissimilarity between G-10 and G11 materials. Let’s delve into this topic to gain a better understanding.

G-10 and G11 are both types of epoxy-based laminate materials that are widely used in various industries. They are known for their exceptional mechanical properties, electrical insulation capabilities, and chemical resistance. Despite their similarities, there are some notable distinctions between G-10 and G11.

G-10 is composed of a glass fabric impregnated with epoxy resin. This combination creates a strong and rigid material suitable for a range of applications. G-11, on the other hand, is similar in composition to G-10, but it contains a higher percentage of epoxy resin, which enhances its electrical insulating properties.

Electrical Insulation:
Due to the increased epoxy content, G11 possesses superior electrical insulation characteristics compared to G-10. This makes G11 more suitable for applications that require higher dielectric strength and resistance to electrical arcing, such as electrical connectors, insulators, and high-voltage applications.

Mechanical Strength:
Both G-10 and G11 materials exhibit excellent mechanical strength and dimensional stability. However, G11 surpasses G-10 in terms of flexural strength and impact resistance. This makes G11 a preferred choice for applications where high mechanical loads or impacts are expected, such as structural components, gears, and bearings.

Temperature Resistance:
In terms of temperature resistance, G-10 can typically withstand higher operating temperatures compared to G11. G-10 can often handle temperatures up to 150°C (302°F) continuously, while G11 is generally limited to temperatures up to 130°C (266°F). However, it’s important to consider specific product data sheets and consult with the manufacturer to ensure suitability for the intended application.

Availability and Cost:
G-10 is more commonly available and widely used compared to G11. The higher epoxy content in G11 makes it more expensive to produce, resulting in a higher cost per unit. Therefore, G-10 is often chosen for applications where the higher electrical insulating properties of G11 are not essential.

In conclusion, the primary differences between G-10 and G11 lie in their electrical insulation properties, mechanical strength, temperature resistance, availability, and cost. By understanding these distinctions, we can better advise our customers on the appropriate material choice based on their specific requirements. As a plastic supplier, it is our commitment to provide accurate information and quality materials to meet the diverse needs of our valued customers.
