Selection of materials for ABS waterproof plastic junction box,
Selection of materials for ABS waterproof plastic junction box:
At present, the main application fields of ABS waterproof plastic junction box are relatively harsh environment on the site and outdoor scene
when considering the safety performance of the product,
the impact resistance, static load strength, insulation, non-toxicity, aging resistance, corrosion resistance and flame retardancy of the material should be considered.
(Non-toxic properties have attracted widespread attention, mainly because if ABS waterproof plastic junction box products is in the case of fire,
generally it will not release toxic and harmful gases when combustion,
the deaths accounted for the majority when there is fire and inhale a large number of toxic gases.
Sealant material selection:
For ABS waterproof plastic junction box products,
the commonly used sealant materials are: PUR, EPDM, Neoprene, Silicon.,
when choosing sealant ring the temperature range, tensile strength, elongation, hardness, density, compressibility and chemical resistance should be taken into account
