NEMA G30
Product Definition:
G30 Glass Fabric Polyamide Laminate is a type of composite material that is made up of layers of glass fabric and polyamide resin. The glass fabric provides the material with high strength and stiffness, while the polyamide resin acts as a bonding agent between the layers of fabric and provides resistance to moisture and other environmental factors.
The term "G30" refers to the grade or quality of the glass fabric used in the laminate. This grade of glass fabric is known for its high tensile strength, dimensional stability, and resistance to abrasion and chemicals.
The G30 Glass Fabric Polyamide Laminate is a versatile material that is commonly used in a wide range of applications, including electrical insulation, printed circuit boards, and structural components. It can be machined, drilled, and formed to create complex shapes and structures, and it offers excellent thermal and electrical insulation properties.
Overall, G30 Glass Fabric Polyamide Laminate is a durable and reliable material that is well-suited for use in demanding environments where high strength, dimensional stability, and resistance to environmental factors are required.
