PEEK is a kind of thermoplastic special engineering plastic, which is non-toxic due to its good mechanical properties, high melting point and biocompatibility. PEEK is a unique semi crystalline and thermoplastic engineering plastic with excellent chemical properties. It is often used in hot water or steam environment. It can maintain a high level of bending strength and tensile strength, can withstand high temperature, the long-term service temperature can reach 260 ℃, and has no smell and good thermal conductivity at high temperature.
PEEK is currently applied in the field of heating non combustion electronic cigarette, such as the shell of heating non combustion electronic cigarette, the base of heating plate, atomization bin and so on. In addition to using peek materials for iqos's cigarette case and heating base, the components of smoke frog's QoQ and sigrig's cigrig cigarette set also use peek materials.
9.5 mm PEEK tube is widely used in the field of electronic cigarette.
