E-cigarettes are electronic devices that mimic traditional cigarettes and are designed to provide a smoking-like experience. It heats a liquid containing nicotine, propylene glycol, glycerin and various flavors to produce vapor for users to inhale.<\/span><\/p>\n

 <\/p>\n

E-cigarettes usually consist of batteries, atomizers and e-liquid, which can avoid harmful substances produced when traditional cigarettes are burned. Due to their smoke-free, tar-free and low-odor characteristics, e-cigarettes are considered a harm-reduced alternative to traditional smoking.<\/span><\/p>\n<\/section>\n<\/section>\n<\/section>\n<\/section>\n

The plastic parts of electronic cigarettes usually include the shell, mouthpiece and other internal components. The following are some common plastic parts and their characteristics:<\/span><\/p>\n

 <\/p>\n

1. Shell: The shell of an e-cigarette is usually made of durable plastic materials to protect the internal electronic components. Common materials include ABS (acrylonitrile butadiene styrene) and PC (polycarbonate), which have good impact resistance, heat resistance, and chemical resistance.<\/span><\/p>\n

 <\/p>\n

2. Mouthpiece: The mouthpiece is the part of the e-cigarette that contacts the user, and is usually made of food-grade plastic materials, such as PCTG (copolyester) or PEEK (polyetheretherketone). These materials are resistant to high temperatures, corrosion, and are non-toxic, and can meet the safety requirements for oral contact.<\/span><\/p>\n

 <\/p>\n

3. Oil tanks and reservoirs: These parts are used to store e-liquid and are usually made of transparent and chemically resistant plastics such as PCTG or PEEK. This allows users to easily check the remaining amount of e-liquid.<\/span><\/p>\n

 <\/p>\n

4. Internal components: Some small components inside the electronic cigarette may also be made of plastic, such as the battery compartment, fixing bracket, etc. The materials used for internal plastic parts usually emphasize high temperature resistance and chemical corrosion resistance to ensure the safety and durability of the device.<\/span><\/p>\n

 <\/p>\n

The selection of these plastic parts mainly considers their chemical stability, high temperature resistance, non-toxicity and mechanical strength to ensure the overall performance and safety of electronic cigarettes. Among them, the types of plastics used arePCTG\u3001PPSU\u3001PP\u3001PC\u3001PEEK\u3001\u900f\u660e\u5c3c\u9f99\u7b49\u3002<\/span><\/span><\/p>\n<\/section>\n<\/section>\n<\/section>\n

\u4e00\u3001PCTG<\/span><\/strong><\/p>\n

 <\/p>\n

PCTG was previously used in cosmetic packaging and plastic water cups due to its glass-like transparency and density, no bisphenol A, excellent food hygiene and flame retardancy, etc. It is currently used in most e-cigarette oil tanks, cigarette holders, cigarette rod shells, etc., and the demand is huge.\u00a0<\/span><\/p>\n

PET resin is a linear homopolymer formed by polycondensation of diol (ethylene glycol, EG) and dibasic acid (terephthalic acid, PTA), while copolyester is a polyester modified by alcohol or acid, including PETG, PCTG and PCTA as well as degradable copolyester. PCTG is a non-crystalline copolyester. In its production process, a certain amount of ethylene glycol is replaced by 1,4-cyclohexane dimethanol (CHDM), which can prevent crystallization and improve processing and transparency.<\/span><\/p>\n

\u4e8c\u3001PPSU<\/span><\/strong><\/p>\n

 <\/p>\n

PPSU is a new type of non-crystalline thermoplastic engineering plastics, which is light, high-strength, good odor at high temperatures, does not contain bisphenol A, will not denature even after repeated heating, has good sterilizability, and can be in contact with water for a long time. And one of its typical applications is baby bottles, so it is also called \"baby bottle material\".<\/span><\/p>\n

\u00a0<\/span><\/p>\n

Polyphenylene sulfone PPSU is synthesized from 4,4'-biphenol and 4,4'-dichlorodiphenyl sulfone through salt formation, polycondensation and other steps. The molecular structure is as follows:<\/span><\/p>\n

 <\/p>\n

PEEK is a thermoplastic special engineering plastic. Due to its good mechanical properties, high melting point, biocompatibility and non-toxicity, it meets FDA certification. Polyetheretherketone (PEEK) refers to a linear aromatic semi-crystalline polymer whose main chain consists of aromatic, ketone and ether bonds. It belongs to the polymer family of \"aromatic polyketone\".<\/span><\/p>\n

PEEK is currently used in the field of heat-not-burn electronic cigarettes for the shell of heat-not-burn electronic cigarettes, the base of the heating plate, the atomization chamber and other parts. In addition to the shell and heating base of IQOS, the QOQ of Yanwa Technology and the CIGRIG smoking parts also use PEEK materials.<\/span><\/p>\n
