What kind of heating film is suitable for <electric heating belt> and <electric heating shawl> heating and insulation?
As a manufacturer of physical electric heaters, how to help customers solve the heating problem of electric heating belts and electric shawls is the most important thing for each heater manufacturer's business, because this is directly related to future cooperation issues, which is also related to its own The growth of ability and performance, here is to provide valuable opinions for the majority of heating film users!
At present, the classification of domestic heating films is roughly as follows: non-woven heating films, carbon fiber heating films, PT heating films, metal heating films, silicone electric heating films, metal heating films, graphene heating films, so how to choose a suitable one among these products Users' own products, I believe that many manufacturers of electric heating belts and shawls pay attention to this problem, so let's analyze how to choose bit by bit!

PET heating film, a film-like transparent heating film, has the advantages of being thin and fast heating. The internal printing principle is mostly used. The inside of the product uses copper tape to conduct electricity and supply power to the heating zone to generate heat. Welding is the main process. The disadvantage is that the joint is not strong enough to fall off, and the bending ability is extremely poor. It is suitable for flat and fixed use. Obviously this product is not very suitable for electric heating belts and electric shawls...
The advantages of the metal heating film are the same as above, and the transparent film principle is also adopted. The internal alloy flat wire is used as the heating conductor. The joints are crimped or welded. They are suitable for flat and fixed scenes. They are also not suitable for bending actions, and the joints are easy to break... …
Silicone heaters will not be introduced too much. Obviously they are expensive and hard. Any piece of silicone heaters can cost more than 50 yuan. I believe that many users can only sell for a belt of only one hundred yuan. It is difficult to bear such a high price. Bottom line...
Graphite heater is indeed a product that heats up faster. The disadvantage is that the price is too expensive, which is more than 3 times that of ordinary heaters. It is suitable for use under 7.4V. The voltage is too high to be used. Everyone knows the main reason for fast heating of graphene. The reason is that the resistivity carried by itself is relatively small, even less than any metal, and the joints are mostly copper strip welding technology.
The non-woven heating sheet and the carbon fiber heating sheet are from the same category. The only difference is the internal heating conductor. The former uses a silicone heating wire as the heating source, and the latter uses a carbon fiber heating wire as the heating source. The packaging is mostly cotton. Good flexibility, suitable for voltages 7.4V-230V, and can be equipped with over-temperature protection and NTC temperature sensing function programs. At present, the market adoption rate has reached 99%, and it is indeed a good heater product.
