In the field of electrical, electronic and insulation materials, 3240 epoxy sheet is a widely used product. Its excellent insulation performance, high temperature resistance, wear resistance and other characteristics make it the preferred material in many industries. However, for buyers, understanding the price of 3240 epoxy board and its influencing factors is the key to making wise purchasing decisions.
The price of 3240 epoxy fiberglass laminate sheet varies depending on many factors, usually ranging from a few yuan to hundreds of yuan per kilogram. This price difference mainly stems from raw material costs, specification residues, production processes, brand influence and market supply and demand.
The main raw materials of 3240 epoxy sheet include epoxy resin, glass fiber, etc. The price fluctuations of these raw materials directly affect the cost of 3240 epoxy fiberglass sheet. When the price of raw materials rises, manufacturers tend to increase the selling price of products in order to maintain profits.
The common thickness of 3240 fiberglass sheet is 0.5mm~50mm, and the thicker the thickness, the higher the price. Its standard size is 1020mm×2020mm, which is cost-effective, while customized sizes require additional charges. Its temperature resistance grade (B grade), flame retardancy (UL94-V0), mechanical strength, etc. also affect the price.
Well-known brands have higher guarantees in product quality and after-sales service, so their product prices are relatively high. However, for buyers, choosing well-known brand products can reduce procurement risks and improve procurement efficiency.
Different production processes have an important impact on the performance and quality of 3240 epoxy sheet. Manufacturers using advanced production processes can produce products with better performance and more stable quality, but the cost is also relatively high. In addition, if special-shaped cutting, CNC engraving and other processes are required, the product price will also be higher.
Market supply and demand relationship: Market supply and demand relationship is an important factor affecting the price of 3240 epoxy resin board. When market demand exceeds supply, product prices tend to rise; conversely, when supply exceeds demand, product prices tend to fall. Therefore, buyers need to pay close attention to market dynamics and grasp changes in market supply and demand so as to purchase at the right time.
1. High-frequency circuit scenarios
In high-frequency circuits, boards with low dielectric loss are preferred to reduce attenuation during signal transmission.
2. High-voltage electrical equipment
Pay attention to the breakdown voltage and temperature resistance of the material to ensure insulation reliability during long-term operation.
3. Mechanical structural components
The bending strength and interlaminar shear strength of the material should be considered to improve the impact load resistance.
1. Qualification compliance review
Check whether it has passed relevant national and international standards certification, such as GB/T 1303 series, IEC 893 series, etc., to ensure that the product meets regulatory requirements.
2. Test data traceability management
A third-party test report is required, focusing on core performance indicators such as electrical strength, dielectric loss, and volume resistivity.
3. Supply chain service capabilities
Delivery efficiency: Inspect the inventory and delivery speed of conventional specification plates.
Customization capabilities: Confirm whether it has the ability of secondary processing (such as cutting, forming, etc.).
After-sales response: Evaluate the feedback speed of technical consultation and exception handling.
1. Bulk purchase incentives
When the single purchase volume reaches a certain scale, you can strive for a tiered discount to reduce the unit purchase cost.
2. Material substitution plan
In non-critical parts, more cost-effective alternative materials can be used to balance performance and cost.
3. Residual material recycling
Negotiate with suppliers for residual material recycling or targeted processing services to reduce material loss rate.
3240 epoxy sheet occupies an important position in many fields due to its excellent performance, but the price fluctuates due to many factors. When purchasing, by clarifying the application scenarios, evaluating the supplier’s capabilities, and implementing cost optimization strategies, we can select truly cost-effective insulation materials while ensuring performance and maximize procurement benefits.
