JF Machinery specializes in designing and developing TPE extrusion lines for the production of TPE-based ribbons, such as TPE tourniquets and TPE exercise bands.
What is TPE (Thermoplastic Elastomer)?
TPE (thermoplastic elastomer), also known as artificial rubber or synthetic rubber. Its products not only have the high elasticity, aging resistance, and oil resistance of traditional cross-linked vulcanized rubber but also have the characteristics of convenient processing and comprehensive processing methods.
TPE raw materials have the following obvious advantages over natural or synthetic latex
- Firstly, Reusable
When TPE products are crushed, they are 100% reusable. It not only simplifies the processing process but also reduces the processing cost. As a result, thermoplastic elastomer TPE materials have become the latest material to replace conventional rubber.
- Secondary, Environmental friendly
It is environmentally friendly and non-toxic. It can be incinerated and does not contain toxic substances, which are not harmful to the environment. Therefore, it is also a more humane, high-grade new synthetic material and an environmentally friendly material by global standards.
We take a medical tourniquet extruder as an example to illustrate the extrusion of thermoplastic elastomers
What is TPE Tourniquet and TPE Extrusion Machine?
Why choose TPE instead of latex as the raw material for the tourniquet?
TPE-Thermoplastic elastomer, a thermoplastic material whose elasticity is close to rubber, is a rubber-plastic composite material. TPE tourniquet has many surface styles, both smooth and delicate, as well as skin texture. TPE tourniquet has good elasticity, small tensile deformation, and most importantly, it has high production efficiency (no vulcanization, production time is three times shorter than rubber) and is also easy to color.
The special blended TPE tourniquet material is a professional nano antibacterial formula that kills 99% of common bacteria in an instant, does not contain special proteins, and fully considers the safety of contact with human skin, not only does it not cause allergic reactions to special groups, And it has excellent elastic recovery or shrinkage.
People in the industry have recognized the excellent environmental protection and non-toxic characteristics of TPE tourniquet material. Meanwhile, TPE tourniquet material fully complies with food, medical, FDA, and other standards. Moreover, tested by the relevant means of the medical industry, it is odorless, almost pollution-free after high-temperature incineration of medical waste, and will not produce a large number of carcinogens like PVC materials. TPE tourniquet material can be in contact with human skin for a long time without any allergic reaction.
What is TPE Extrusion?
Extruded products using TPE as raw materials are quite extensive, such as fitness equipment tension tubes, tension bands, tension strips, sealing strips, rubber bands, earphone cords, adhesive carpets, tourniquets, etc.
Extrusion production using TPE as a raw material has quite a lot of requirements for extruders, We have overcome many technical difficulties, that our machine avoids the following problems that are easily generated when extruding TPE products:
- Extrusion output instability
- The rough surface of the finished product
- Finished product deformation
- The surface of the finished product has stripes
The TPE tourniquet extrusion line is our most mature TPE production line, equipped with a patent slitting and cutting machine. Fully automatic operation without manual intervention.
