What is TPE Extrusion

Extruders are used for creating a good range of food products. Their design and specifications should be tailored for the intended application. The extruders feed material may include one solid or many solid and liquid ingredients. The solid ingredients are mostly grain, pulse, and root-based foods, sweeteners, minerals, and vitamins. they’re utilized during a sort of particle size distribution. The liquids include water, oil, liquid sweeteners, and hues. The ingredients are typically mixed, transformed into a melt/dough, and formed into the specified product shape. there’s an excellent deal of interaction between the feed ingredients, extruder design, and operating conditions.

What is TPE

Thermoplastic elastomers are copolymers that contain materials with thermoplastic and elastomeric properties. These materials exhibit properties of both rubbers and plastics and to qualify as thermoplastic elastomer, the fabric must have the subsequent characteristics:

  1. Return to its approximate original shape after the fabric is stressed
  2. Absence of serious creep.

TPEs are strong, abrasion-resistant, and oil and grease resistant. they’re highly resilient, impact and tear-resistant. TPEs are available as rigid and soft compounds and may be easily coloured. Since most TPEs require little or no compounding, the materials exhibit consistency between batches, allowing high repeatability within the finished product. TPEs are an economic material choice for several products. As a result, they’re widely used plastics for industrial applications.

TPEs are used widely in automotive, home appliance, medical device, and building and construction applications.

The Advantages of TEP Extrusion

Thermoplastic elastomers TPE are characterized by their elastic usage and thermoplastic processing properties. supported the chemical-morphological structure, they’re divided into TPE-S, TPE-O, TPE-E, TYPE-A and TPE-V. Different methods are applied for the compounding of thermoplastic elastomers like pelletizing or direct extrusion in film or sheet.

1、Visualize the wear of wearable parts

Since it is easy to open, the degree of wear of threaded components and barrel bushings can be found at any time, so that effective repair or replacement can be carried out.

2、Reduce production cost

When manufacturing masterbatches, it is often necessary to change the colour, and if it is necessary to change the product, the open processing area can be opened within a few minutes, and in addition, the mixing process can be analyzed by observing the melt profile on the entire screw. At present, the ordinary twin-screw extruder needs to be cleared with a large amount of clearing material when changing colours, which is time-consuming, power-consuming and wasteful of raw materials.

3、Improve labour efficiency

During equipment maintenance, the ordinary twin-screw extruder often has to remove the heating and cooling system first and then withdraw the screw as a whole.

4、High torque and high speed

At present, the world’s twin-screw extruder development trend is to high torque, high speed, low energy consumption direction, the effect of high speed is to bring high productivity. The split twin-screw extruder belongs to this category, and its speed can reach plus 500 rpm.

5、A wide range of applications

A wide range of applications can be applied to the processing of a variety of materials.

6、High output, high quality and high efficiency

With the other advantages of the common twin-screw extruder, it can achieve high output, high quality and high efficiency.
