Shell material
Nylon (English name: Polyamide (PA for short): At present, there are two kinds of "nylon 6 and nylon 66", which are thermoplastic resins with repeated amide group - [NHCO] - on the main chain of the molecule.
Advantages: heat resistance, low friction coefficient, wear resistance, self-lubricating, shock absorption and sound attenuation, oil resistance, weak acid resistance, alkali resistance and general solvents, good electrical insulation, self extinguishing, non-toxic, odorless, and good weather resistance.
PVC: chemical name PVC
Advantages: folding resistance, light resistance, water resistance and oxidation resistance
Hardware material
Copper gilding
Advantages: ensure that the copper surface does not fall off
O-ring
Rubber: a double insulated wire
Advantages: good elasticity, cold resistance, high temperature resistance, oil resistance, ultraviolet resistance, good flexibility and high strength
Sealing washer
Silica gel: can be divided into organic silica gel and inorganic silica gel
Advantages: heat resistance, cold resistance, dielectric property, ozone resistance and atmospheric aging resistance
The four materials mentioned above are the most formal and qualified materials used to make waterproof connectors. As we all know, the quality, service life, safety performance and environmental protection performance of products are directly determined by the quality of materials. Therefore, it is recommended that when choosing waterproof connectors, you must study the materials used, so that you can better find safe and reliable connector products.
