PC : material properties with high impact strength, good dimensional stability, colorless and transparent, good colorability, good electrical insulation, corrosion resistance, wear resistance, but poor self-lubrication, stress cracking tendency, high temperature It is easily hydrolyzed and has poor compatibility with other resins.
PVC：Chemical and Physical Properties Rigid PVC is one of the more widely used plastic materials. PVC material is an amorphous material. In practical use, PVC materials often add stabilizers, lubricants, auxiliary processing agents, pigments, impact resistance agents and other additives.
Plastic junction boxes play an important role in solar cell modules. With the application of the market and our customers, the company has developed a variety of junction boxes that can achieve high rated current, excellent heat dissipation, and high water resistance through design and technology. Customer choice.
The use of plastic junction boxes has been widely spread and sold in the market. It can be seen in many places such as construction sites, hotels, coastal factories, ship cabins, etc., indicating that plastic junction boxes are widely used.
The metal junction box is suitable for some easily disturbed lines, such as data signal lines or other weak current signal lines. It requires the use of metal wire pipes and iron junction boxes, and the pipes and boxes are required to be grounded. Buildings and sites with high fire protection requirements. Explosion-proof junction boxes are used in oil depots or other flammable and explosive sites, and are required to be sealed and grounded. Plastic junction boxes are subject to strict production specifications, and flame retardants are also added to the materials of plastic junction boxes, which are generally used in some places with low requirements, such as general lighting and power lines.
