Differences Between Rogers 4305 and 4350B

Hits : 6

The sheet materials of Rogers 4305 and 4350B contrast in the following ways:

Material type: Rogers 4305 is a polytetrafluoroethylene (PTFE for short) filled fiberglass material, while Rogers 4350B is a ceramic filled fiberglass material.

Dielectric Properties: Rogers 4305 has a relatively low dielectric constant, while 4350B has a high dielectric constant. The dielectric constant is an important parameter for measuring the electrical properties of a material, which determines its capacitance, inductance, and other characteristics at a specific frequency.

Mechanical Properties: Rogers 4305 has better mechanical properties, including strength and wear resistance. While 4350B may be slightly inferior to 4305 in terms of mechanical properties.

Temperature Resistance: Rogers 4305 has a wide range of temperature resistance and is suitable for a variety of ambient temperatures. The temperature range of 4350B may be relatively narrow, depending on the application.

Chemical Resistance: The ceramic filler material of Rogers 4350B has good chemical resistance and is able to resist the erosion of various chemical reagents, making it suitable for application scenarios that require exposure to chemical reagents. The PTFE filler material of Rogers 4305 may be slightly less resistant to chemicals than 4350B.

Cost: The cost of Rogers 4305 and 4350B may vary depending on production lot, brand, region, and other factors. In general, ceramic-filled sheet materials may cost relatively more but offer better performance. Therefore, the choice of plate material needs to be weighed against the specific application requirements and budget.

Processing Difficulty: The processing difficulty of Rogers 4305 and 4350B may vary between production lots and manufacturers. In general, ceramic-filled sheet materials may be difficult to process and require more specialized equipment and skills. Therefore, the selection of plate material needs to be considered in light of specific processing requirements and equipment conditions.

Rogers 4305 and 4350B sheet materials differ in dielectric properties, mechanical properties, chemical resistance, cost and processing difficulty. Which material to choose depends on the specific application needs and design requirements.

In addition, it should be noted that there may be some differences between different production batches or the same type of sheet material produced by different manufacturers. Therefore, in practical applications, it is recommended to select the appropriate sheet material based on the specific product specification or communication with the manufacturer.

The durability of Rogers 4305 and 4350B depends on the specific application scenario and environmental conditions.

In general, Rogers 4350B has a higher dielectric constant and lower loss characteristics for high frequency and high speed application scenarios. Its ceramic filler material has better heat and chemical resistance, resulting in better durability.

Rogers 4305 , on the other hand, is a polytetrafluoroethylene (PTFE for short) filled fiberglass material with better mechanical properties and temperature resistance, making it suitable for application scenarios that require greater stress and higher temperatures.

Rogers 4350B is more suitable for copper laminates for circuit boards. It is a ceramic-filled glass fiber material with excellent electrical and mechanical properties that meets the circuit board's requirements for dielectric constant, loss characteristics, mechanical strength and heat resistance.

In addition, Rogers 4350B has good processing performance and can be cut, drilled, soldered, and other processing operations, making it suitable for a variety of electronic applications that require processing into different shapes and sizes.
