FR-4 epoxy plate in electric water heater

Discussion on the advantages of FR-4 epoxy plate in electric water heater

The electric water heater, as the name suggests, is a water heater heated by electricity. Because of its shortcut, convenience and environmental protection, it is loved by consumers. I think most people, except some in the industry, don’t know that the electrical material used for insulation and heat insulation on it is FR-4 epoxy. For this reason, I summarized some information, hoping to help you.

FR-4 epoxy plate

First, I’ll show you what FR-4 epoxy board is. What are the characteristics?

It is made of special electronic cloth soaked in epoxy phenolic resin and other materials by high temperature, high pressure and hot pressing. It has the characteristics of easy processing, high temperature resistance, insulation, low thermal conductivity, low water absorption, moisture-proof and arc resistance.

Now I would like to talk with you about the advantages of FR-4 epoxy board for electric water heaters.

1. environmental protection. Nowadays, people pay more and more attention to environmental protection. And FR-4 epoxy board is halogen-free, non-radiation to the human body, non-toxic, even if burned will not have a lot of smoke and pungent odor.

2. Insulation. The electric water heater, as its name implies, is the use of electrical energy. The insulation is unavoidable. The resistance of FR-4 is very large (insulation resistance (D-24/23) after immersion is greater than 5 x 108 omega).

3. The coefficient of thermal conductivity is low. One of the most important features of a water heater is insulation. The FR-4 epoxy plate itself has a high temperature of about 150 degrees, and it will not pass the heat to other materials, not only to other materials, but also to help the inner gallbladder of the water heater for two times.

4. Easy to process. With the continuous development of water heater technology, today’s water heaters have diversified. It is suitable for the needs of all kinds of people. The FR-4 epoxy board has the characteristics of easy processing and good toughness. It can satisfy the processing of any kind of water heaters, and it is undoubtedly icing on the cake for the development of water heaters.

5. moisture-proof. Water heaters are usually installed in the bathroom. When people take a bath, they have a lot of heat. Naturally there will be fog water. There must be some moisture. The FR-4 epoxy board has the characteristics of low water absorption, which can fundamentally extend the life of the water heater. It can be described as saving, saving time and saving money.

The above five points are the advantages of FR-4 epoxy board on the electric water heater. Of course, only part of it. If you want to know more about this material, you can contact us.Email is
