Product Description

PE And Iron Sheets Co Extrusion Process Improve The Stability Of PE Plastics To Ultraviolet Rays And Oxidation

 

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.

Co extrusion profiles can use many different materials, according the product features to adopt appropriate materials. So it is widely used for automotive, appliances, furnishings, construction, toys.

Co-extruded PVC are used in a variety of applications, including adding flexible seals to rigid profile to avoid the requirement for a secondary extrusion. The co-extrusion process is regularly used to add coloured strips in profile for identification and visual requirements.

The co-extrusion process combines two or more different materials in a single extrusion process. Two or more extruders deliver the desired plastics to a single extrusion head, or die, to manufacture the part. The materials can be combined or layered, using different compounds for the layers. Preferred Plastics’ co-extrusion capabilities include:
Dual hardness profiles using multiple resins
Simple and complex shapes, manufactured to industry standard
Small and large shapes
Wide range of thermoplastic materials, including PVC, ABS, TPU, and TPE.

 

Characteristics and applications of PE

 

PE plastic is odorless and non-toxic, feels like wax, can withstand low temperature, good chemical stability, low water absorption, high rigidity, hardness and strength, and strong radiation resistance. But PE plastic is very sensitive to environmental stress (chemical and mechanical action) and has poor heat resistance.

PE plastics are widely used and can be processed by blow molding, extrusion, injection molding and other methods. They are widely used in film manufacturing, hollow products, fibers and daily sundries. It is further divided into high-density, low-density and linear PE. The most daily applications are processed into various plastic films and plastic sheets. High-density PE plastic is suitable for making shock-absorbing, wear-resistant and transmission parts. In actual production, in order to improve the stability of PE plastics to ultraviolet rays and oxidation, and to improve processing and performance, a small amount of plastic additives needs to be added.
