Interpretation of Phenolic Laminated Cloth Rod Models and Standard Specifications

1. Definition and classification of phenolic laminated cloth rods

Phenolic laminated cloth rods refer to a composite material product made of fiber cloth or cardboard as the base material and phenolic resin as the adhesive, which is pressed and molded. It has excellent properties such as high temperature resistance, corrosion resistance, hydrolysis resistance, and good electrical insulation, and is widely used in electronics, machinery, chemical industry and other fields.Phenolic laminated cloth rods are divided into various models according to different base materials, different pressing processes and different conductive properties, including: XPC, FR-2, FR-4, G-10, G-11 and FR-5.

2. Application of phenolic laminated cloth rods

Phenolic laminated cloth rods are mainly used to make insulating structural parts in industries such as high-voltage electrical appliances, computer peripherals, automobiles, air conditioners, and electronic appliances, such as insulating boards, socket bases, motor brake brackets, high and low voltage electrical appliances, heat exchangers, and terminal blocks.

3. Characteristics and application scope of different types of phenolic laminated cloth rods

XPC  

XPC is a very practical phenolic laminated cloth rod. It has the characteristics of good thermal conductivity and high dimensional stability. It is suitable for making some insulation boards and socket bases that do not need to be too high.

FR-2

FR-2 is a commonly used phenolic laminated cloth rod. It has the characteristics of good heat resistance, good moisture resistance, and high mechanical strength. It is suitable for making single-layer and double-layer socket bases, insulation boards, and electronic appliances.

FR-4

FR-4 is a cost-effective phenolic laminated cloth rod. It has the characteristics of good flame retardancy, good insulation, and high mechanical strength. It is suitable for making multi-layer socket bases, electrical and chemical parts, electronic appliances, etc.

G-10  

G-10 is a high mechanical strength phenolic laminated cloth rod. Due to its high hardness, good friction resistance, and high pressure strength, it is suitable for making mechanical structural parts and brackets.

 G-11  

G-11 is a high-temperature and high-pressure phenolic laminated cloth rod, which has the characteristics of high temperature resistance and strong arc resistance, and is suitable for making high-temperature and high-pressure electrical appliances, heat exchangers, etc.

FR-5

FR-5 is a high-heat-resistant phenolic laminated cloth rod, which is suitable for making high-temperature and high-pressure electrical appliances, heat exchangers, etc.

4.Standard specifications for phenolic laminated cloth rods

The standard specifications for phenolic laminated cloth rods are generally formulated by the country or industry. The common standard specifications include the US IPC-4101, the European EN 60893 and the Chinese GB/T 1303. These standard specifications mainly stipulate the various indicators of the quality and performance of phenolic laminated cloth rods, such as curing time, heat deformation temperature, destruction voltage, surface resistance, etc. Users can choose products that meet their own requirements according to their needs.
