The twin housing tells you the composition of the plastic junction box

With the development of economy, the use of plastic junction box is becoming more and more widely, such as: the cabin, outdoor electrical, communications, fire equipment, petrochemical industry, household, electronics, mining, subway, quarry, hotel, coastal factories, ships, large factories, the unloading port, school will see anytime and anywhere, all this also illustrates the plastic box USES the general.

Now I would like to introduce to you the composition of the plastic junction box:

1. Polycarbonate, with strong material performance, high impact strength and stable size, is a colorless and transparent material with good coloring, excellent electrical insulation, good corrosion resistance and abrasion resistance;However, there is a tendency of stress cracking, high temperature hydrolysis, and other resin compatibility is poor.

2, PVC, is one of the most widely used plastic materials;The plastic junction box is an amorphous material;In actual use, stabilizer, lubricant, colorant, anti - impact agent and other additives with various functions are often added.
