Customized Plastic And Copper Co-Extrusion Profile PVC Conductive Strip Color Optional

Description

In standard extrusion, solid plastic pellets are gravity fed into a forming mechanism, where jacketed compression screws melt and feed the materials into a die. By contrast, coextrusion involves multiple extruders forming layered or encapsulated parts. Sometimes five or more materials are used in a single cycle, with each extruder delivering the precise amount of molten plastic needed for the operation.

Unlike ordinary plastic mixing, each individual plastic retains its original properties, but is combined into a compound-material part. If mixed prior to extrusion, the characteristics of the individual materials may be altered, but the end result is a homogeneous product.

Not all plastics are suitable for coextrusion because some polymers will not adhere to others, although introducing a conductive middle layer can often solve this problem. Plastics with drastically different melting temperatures are also unsuitable for the process, as degradation will occur in the lower melting material. Finally, PVC and acetals should never be coextruded together because of the potentially violent reactions that can occur when they are joined.

Here we recommend PVC co-extruded with copper, normally use on LED light strip.

Advantages of PVC co-extruded with copper 

1. High quality and low price

2. Mechanical properties: high mechanical strength, flame retardant, heat insulation and self-reflection, strong acid and alkali resistance, good weather resistance (long-term use temperature should not exceed 60 ℃ ). It has good chemical and geometric stability, and is mostly used in architectural decoration and profiled products.

3. Excellent electrical insulation, comparable to hard rubber (suitable for making wire and cable insulation layers, seals, etc.)
Copper bar: dense and uniform structure, no pores, blisters, high purity, less inclusions, and good electrical and thermal conductivity. The oxygen content is stable, the oxidation is slow, and the performance is superior. It is suitable for electrical discharge machining materials of various high-precision molds or electrical accessories such as high-voltage electrical switches.
Scope of application: home appliance shells, toys, living rooms, restaurants, exhibition halls, art halls, offices, shops, shopping malls, hotels and other various LED spotlights, LED background wall lights and other surface mounted snap-on lighting fixtures.
