The sealing ring, in our daily life, is mainly used in the preservation and shatterproof sealing of heat preservation boxes, water cups, rice cookers and other daily articles.It greatly facilitates our life, and e-cigarette silicone sleeve also needs to use the sealing ring, do you know?
The performance of e-cigarette silicone seal ring mainly includes:
1. Excellent sealing performance, waterproof and leakproof.
2, fresh effect is good, completely non-toxic and tasteless.
3, can be placed under high temperature heating, no deformation, no production of harmful substances.
4. Good tensile resistance, specially tested.
5, long-term use of the same yellow color does not fade.
6, corona resistance, arc resistance, high and low temperature resistance, aging resistance, high temperature resistance, in line with FDA and SGS standards.
Advantages and disadvantages of e-cigarette silicone sealing ring:
Heat resistance: silicone rubber has much better heat resistance than ordinary rubber, can be used almost forever at 150° without performance change, can be used continuously for 10000 hours at 200°, can be used for a period of time at 350°.It is widely used in heat resisting situations, hot water bottle sealing ring, heat resisting handle of pressure cooker ring.
Cold resistance: ordinary rubber delay is -- 20° -- 30°, that is, silicone rubber is still good elasticity at -- 60° -- 70°, some special formulation of silicone rubber can also withstand very low temperature, such as: low temperature sealing ring.
Disadvantages: not recommended for most thickened solvents, oils, thickened acids and diluted sodium hydroxide.
