Flexible Tube, Hose and Profile applications

Electrically conductive PRE-ELEC® plastics for flex tubes, hoses and profiles

Are you in the business of making working environments safe for everyone? There are many mechanisms for increasing safety and these can be implemented in various forms. Here are some examples of where our thermoplastic elastomers can be used to eliminate static charging and reduce the following risks:

  • Hazardous atmospheres (ATEX) — sparks may trigger explosions
  • Hospitals — sparks may harm patients and damage expensive equipment
  • Clean rooms — sparks damage electronic components and may cause faulty devices

On top of controlling static electricity, there are also other use cases such as contact sensors and healthcare textiles.

Conductive thermoplastic elastomers — a sustainable alternative to rubber and metal

Conductive thermoplastic elastomers

  • Protect against static charging
  • Enable sensoring
  • Protect against electromagnetic interference (EMI)
  • Can be used to modify electric fields

Thermoplastic elastomers are a sustainable, recyclable, and economical option for metal and rubber composites. Also, they can be processed with typical plastics processing machinery.

Sawdust or flour in the air can create an explosive environment that can be alighted by an unintentional static discharge.

Conductive elastomers for extrusion applications

Our PRE-ELEC® compounds can be used in flex tubes, hoses, and profiles with unique special features.

Flex Tubes

Flex tubes made of PRE-ELEC® compounds are strong and flexible. They can be used in multi-component structures. Using our conductive compounds you guarantee conductivity, high abrasion resistance, high flex-life, durability, easy processability, and flexibility even at low temperatures.

More information on suitable grades can be found in our Data Center.

Hoses

Hoses made of PRE-ELEC® compounds can be used in multi-layer structures. This means the inner and outer tubing can have different chemical and/or physical resistances. Conductive hoses are typically used to convey hospital gases, possibly in a combination of multiple materials, such as PVC with TPU inner liner. Our compounds provide constant conductivity and are resistant to bending and flexing for the end-product.

More information on suitable grades can be found in our Data Center.

Profiles

Profiles made of our compounds provide various compression properties for sealings. They resist permanent deformation and, as a result, are suitable for, for example, pressure detection.

Our compounds make profiles soft and easy to deform, which provides a good contact or tightness when installed. The abrasion resistance for repetitive loading is good. Suitable for use in a wide range of temperatures, the materials can be used in different ambient conditions without cracking or creeping.

Example: safety edge profiles

A safety edge made of a PRE-ELEC® compound makes it safe to close a garage rood. When the door touches something solid, such as a car or a person, the profile bends temporarily. The bending acts as contact detection and sends a signal to the door mechanism to stop its movement. Unless such safety measures are included in systems operating with powerful motors, a serious level of danger is present.

In Figure 2, the safety edge operation principle is demonstrated. The pressure-activated contact sends an electric current between + and – terminals, which can be used as an input for electronics, i.e., current implies a contact, and lack of current implies the safety edge is not in contact with anything.
