About extrusion machine： TPE thermoplastic elastomer industry applications, there are definitely areas you don’t know about!

About extrusion machine
Thermoplastic elastomers are currently used in a wide range of industries, including automotive, home electronics equipment, wire and cable, food packaging, medical devices and many others. The downstream application market is driven by continuous product innovation from manufacturers, who have a wide range of product designs for different applications.

Ⅰ.Medical industry requirements

1. chemical inertness: does not react with drugs or body fluids, or does not itself absorb drugs.
2. Rejection: does not lead to inflammation or foreign body reactions.
3. Hemocompatibility: no haemolysis, no clotting.
4. durability: no loss of elasticity and other properties for long-term implantation
5. non-deformation after necessary disinfection.
6.processability: easy to process into complex shapes.

Ⅱ.Footwear industry requirements
1. Processibility: easy to shape, conducive to the production of complex structures.
2. Comfort: high elasticity and breathability, good shock absorption, not stuffy.
3. Abrasion resistance: the material of the shoe outsole needs to be considered for abrasion resistance.
4. Low temperature resistance: shoes will not become hard and brittle in colder climates.
5. High coefficient of friction: anti-slip effect.
6. Tear strength: to enhance the durability and cut resistance of the shoe material.

Ⅲ.Modified asphalt industry requirements

1. Elongation: to enhance the ductility of the asphalt to avoid cracking of the asphalt.
2. elasticity: so that asphalt can rebound after pressure, to avoid permanent deformation resulting in pavement deformation.
3. low and high temperature resistance: so that the asphalt is less likely to become brittle and harden at low temperatures, and the material has a low needle penetration at high temperatures.

IV. Automotive industry requirements

1. High tear strength: to enhance the durability and cut resistance of the parts.
2. low compression deformation: to ensure the sealing effect of parts and shock absorption effect.
3. low odour VOC: protects passengers from the hazards of VOCs.
4. weather resistance: no cracking or loss of performance over long periods of time in the natural environment, delaying the life of the seal.
5. ageing resistance: no cracking and loss of performance when subjected to thermal oxygen ageing, delaying the life of the seal.
6. fatigue resistance: less loss of resilience of parts subject to repeated use.
7. Excellent comfort: some interior parts come into contact with people, taking into account human comfort.
8. oil resistance: automotive environment contact with petrol to avoid material absorption of petrol dissolution and swelling affecting performance.

V. Cable industry requirements

1. Oil resistance: to avoid the material absorbing petrol and swelling to affect the performance
2. tear and crack resistance: to enhance the durability and cut resistance of the cable.
3. flexing resistance: to ensure that the cable after repeated bending still maintain the physical properties of the material.
4. weather resistance: subject to thermal and oxygen aging will not occur cracking and loss of performance, thereby protecting the metal wire from damage.
5. water and acid resistance: to cope with the complex use of the environment, can not make the metal exposed or absorb water leakage.
6. Abrasion and crush resistance: to avoid the material being squeezed and dragged when the elastomer wears out resulting in the metal wire being exposed to the air.
7. hardness: hardness requirements less than 80A
8. environmental protection and flame retardant: the cable will be hot for a long time through the current, or arc, short circuit, etc. resulting in material combustion, in order to avoid these safety accidents, the material is required to have a certain degree of flame retardancy.
9. high and low temperature resistance: -40 ℃ to 100 ℃ to do repeated cycle test, the requirement is not cracked, voltage resistance 1KV (dipped in salt water for 10 minutes)

VI. Food packaging

1. FDA (US Food and Drug Administration) approved: consider personal safety.
2. Good sealing: to ensure that the food does not leak, or that the vacuum packaging does not enter the air.
3. Having a certain strength: it will not break easily.
