Description

Co-extrusion is defined as the process in which two or more plastic materials are extruded through a single die. In this process, two or more orifices are arranged in such a manner that the conjoint merging and welding of the extrudates takes place and before chilling, a laminar structure forms. In co-extrusion, a separate extruder is used to fed every material to the die but the orifices can be arranged in such a manner that each extruder provides two or more plies of the same material.
Co-extrusion may be employed in the processes of Film Blowing, Extrusion Coating, and Free Film Extrusion. The general benefit of the co-extrusion process is that every laminate ply imparts a required characteristic property like heat-sealability, stiffness, & impermeability, all of which are impossible to attain by using any single material.
It is evident that co-extrusion is a better process than a single layer extrusion. For instance, in the vinyl fencing industry, co-extrusion process is used for tailoring the layers on the basis of whether these are exposed to weather or not. Generally, compound's thin layer is extruded that contains high-priced weather resistant additives. This extrusion is done on the outside, whereas inside there is an additive package which is more suitable for the structural performance and impact resistance.

And co-extruded conductive strip normally are LED track accessories, copper-plastic composite conductive track, its advantages are that the copper wire does not loosen and fall off, the electrical conductivity and thermal conductivity are good, the oxygen content is stable, the oxidation is slow, and the performance is superior. Electrical accessories such as electrical switches. PP/PVC/ABS and other materials, with copper strip co-extrusion, can be combined with your needs.

What is the difference between extrusion and co-extrusion?

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.

Features of co-extruded conductive strip

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.
