Based on material, thermal mugs can be broadly categorized into stainless steel, titanium, and ceramic-lined varieties. Stainless steel thermal mugs currently dominate the market. Common stainless steel types include food-grade 304 stainless steel (06Cr19Ni10) and the more corrosion-resistant 316 or 316L stainless steel. Industrial-grade 201 stainless steel exhibits poor corrosion resistance, and its prolonged use may pose a risk of heavy metal leaching. Titanium thermal mugs feature exceptional material stability and resistance to acid and alkali corrosion, in addition to being lightweight; however, they come at a higher cost. Ceramic-lined thermal mugs offer an interior with a smooth, pleasant texture and are free of metallic odors, though they are fragile and tend to be heavier overall.
Based on thermal insulation technology, they can be classified into standard thermal mugs and vacuum-insulated thermal mugs. Standard thermal mugs retain heat for a relatively short duration-typically less than three hours. Vacuum-insulated thermal mugs utilize a vacuum extraction process to enhance thermal performance, thereby extending heat retention periods to eight hours or more. The duration of heat retention is influenced by factors such as the mug's structural design, material thickness, capacity, mouth diameter, and the degree of vacuum achieved.
Based on functionality and design, thermal mugs can be categorized into basic functional models, smart temperature-control mugs, cultural and creative collaboration editions, and application-specific models. Smart temperature-control mugs are equipped with intelligent thermal management systems, enabling features such as real-time water temperature monitoring via a dedicated mobile app. Cultural and creative collaboration editions incorporate elements of culture, art, or intellectual property (IP). Application-specific models include wide-mouth mugs designed for use with coffee machines, large-capacity models intended for family use, and lightweight models optimized for daily commuting.
