What brand of portable heating (heating paste) is good? Which is the earliest and most professional warm baby manufacturer in China?

The heating principle of human body heating is exothermic oxidation reaction. Iron powder reacts with oxygen in the air to release heat. The key technology of portable heating is the control of reaction time and temperature. How to keep close to constant temperature and continuous heating is difficult; Moreover, in the process of use, blanking cannot occur, because once blanking and raw materials accumulate, the reaction speed will be uneven and the temperature will be too high, which will easily cause burns. After years of production and R&D practice, Hengda Company has completely mastered this technology, which not only makes the products evenly heated during the heating process, but also makes the products look flat, and because it is independently developed, it can adjust the temperature and heating time of the products at will, thus being more suitable for the specific needs of various products.

China's largest and most professional manufacturer of warm babies should be Xinyang Nuclear Hengda Industrial Company. Hengda Company, founded in 1985, is one of the earliest companies in China nuclear industry to produce civilian products. In 2003, at the request of customers in Hong Kong, Hengda Company began to develop warm stickers. With the strong R&D team of Hengda Industrial and Military Enterprise, the enterprise finally developed and customized all the mechanical equipment and heating materials by itself, and finally produced the first warm baby sticker, which is the first warm baby sticker from China. Since then, China's warm paste industry has finally got rid of its dependence on Japanese equipment and materials and embarked on the road of complete localization.

This product was not sold in China at that time, but mainly exported to Hong Kong. Several major supermarket chains in Hong Kong, such as Watsons, Wanning and Japan City, are all supplied by Hengda. Due to the excellent quality of our products, this cooperative relationship has continued until now. In 2004, our warm bags began to be exported to America, Europe, Russia and other countries and regions.

In 2005, Hengda Company launched the first domestic independent brand "Nuclear Letter" and began to promote its products throughout the country. In 2007, the company launched the high-end brand "Shangle Portable Warm", and the main channels were domestic large-scale KA chain systems and international KA stores. In 2008, Hengda Company took the lead in launching the online sales monopoly brand "Babe Bear", which had a huge impact on Taobao that year. In 2009, "Babe Bear" quickly became the first brand product for Taobao online baby warmers.
