Key Properties of FR4 Epoxy Sheet for Industrial Use

FR4 epoxy sheet is a versatile material widely used in industrial applications due to its exceptional combination of properties. This composite material, consisting of woven fiberglass cloth impregnated with epoxy resin, offers outstanding electrical insulation, mechanical strength, and thermal stability. FR4 sheets are flame-retardant, possess low moisture absorption, and maintain dimensional stability under varying environmental conditions. These key attributes make FR4 epoxy sheets ideal for manufacturing printed circuit boards, electrical insulators, and structural components in diverse industries such as electronics, aerospace, and automotive. The material's reliability, durability, and cost-effectiveness have solidified its position as a crucial element in modern industrial manufacturing processes.

Is G10 UV Resistant for Outdoor Use?

G10, a fiberglass-epoxy composite material renowned for its exceptional strength and durability, is not inherently UV resistant for outdoor use without additional protection. While G10 sheet exhibits excellent mechanical properties and chemical resistance, prolonged exposure to ultraviolet (UV) radiation can gradually degrade its surface, affecting both its appearance and performance. The epoxy resin component of G10 is particularly susceptible to UV-induced degradation, which can lead to discoloration, chalking, and potential structural weakening over time. However, with proper protective measures such as UV-resistant coatings or treatments, G10 can be effectively used in outdoor applications where its unique combination of strength, lightweight nature, and electrical insulation properties are desirable.

Phenolic Resin vs Epoxy Board: Which Performs Better Under Heat?

When it comes to thermal performance, epoxy boards generally outperform phenolic resin sheets under high heat conditions. Epoxy boards exhibit superior heat resistance, maintaining their structural integrity and electrical insulation properties at higher temperatures. While phenolic resin sheets offer good heat resistance, they tend to degrade more quickly when exposed to extreme temperatures. Epoxy boards typically have a higher heat deflection temperature and can withstand continuous operating temperatures up to 150°C or higher, depending on the specific formulation. In contrast, phenolic resin sheets usually have a maximum continuous operating temperature around 120-130°C. This superior thermal stability makes epoxy boards the preferred choice for applications requiring excellent performance under intense heat conditions.
