PTFE - Shrink tubing

PTFE shrink tube 

Shrink rates 4:1 or 2:1
AWG and inch sizes
Standard and special wall thicknesses

We are a manufacturer of PTFE shrink tubing and, in addition to the common standard sizes with shrink ratios of 2:1 or 4:1, we also produce shrink tubing products specially tailored to your application.

Our team has decades of experience in the design, manufacture and further processing/assembly of PTFE shrink tubing. We have been producing fluoroplastic heat-shrink tubing on our modern production facilities since 2022.

Fluoroplastics such as PTFE are characterized by their very high resistance to aggressive media. Due to their particularly smooth surface, they are anti-adhesive and can be used permanently under high thermal stress in both very cold and very hot environments. For further properties, please refer to our technical data sheet..

In addition to common standard sizes in the normal-walled (TW) range, we also design, sample and then mass-produce PTFE shrink tubing specially adapted to your application.

Shrink rates up to 6:1, inner diameter, wall thicknes or even a defined length shrinkage are configurable. We are your development partner and support you in getting your projects ready for series production.

Standard dimensions are available from stock in 1.22 m lengths or on spools at short notice. We also manufacture piece lengths according to your specifications.

In addition we manufacture shrink tubing for special components on modern production facilities at favorable conditions or take over the shrinkage of the provided components in our plant.

In our production we exclusively use REACH and RoHS compliant raw materials. If you have any further documentation requirements, please do not hesitate to contact us.

We are looking forward to your request!

  • The enivronmental influences must be checked with regard to possible damage to the bearings.
  • Elastomer bearings and bearing surfaces must be free of contamination. Loose particles are not permissible.
  • The bearing surfaces must be free of ice and snow, grease, solvents, oils or separating agents. This must be ensured by suitable measures.
  • The bearing surfaces must be carefully deburred to protect the bearing.
  • The joint between the building protection mat and the vertical formwork is to be sealed by means of suitable adhesive tape; alternatively the building protection mat can be pulled up and fastened to the vertical formwork.
  • Individual surface imperfections must not exceed 100 mm² and must not deviate in depth from the surrounding surface by more than 2.5 mm. The total area of the surface imperfection must not exceed 10%.
  • The bearing areas must be designed in accordance with the design-specific technical specifications and standards. In general, edge distances should be provided. The elastomeric bearing should be located within the reinforcement.
  • If the bearings are used with steel contact surfaces, the steel surfaces should be at least 25 mm larger circumferentially than the bearing.
  • If the elastomeric bearings are tamped underneath, special care must be taken to ensure good mortar quality. The elastomeric bearing must not be overloaded at specific points. The load of the structure to be supported by the bearings should not directly load the bearing exclusively via wedges, unless a sufficiently stiff steel plate is interposed for load distribution. The wedges must be removed again after the underpacking material has hardened.
  • The lateral surfaces of the bearings must not be impeded in their planned deformation.
  • Each component must be separated horizontally and vertically from the adjacent components by joints in such a way that the intended support (statics) can become effective. It should be noted that joint fillings, e.g. joint compounds, profiles made of foam or panels made of mineral wool or foam, can impair the deformability can be impaired. In the case of in-situ concrete execution, the proper production of the bearing joint must be ensured.
  • In the case of horizontally displaceable components, it must be checked whether fixed points or fixed zones must be arranged to determine the zero point of movement of the component to be supported to be stored. It should be noted that unintentional fixed points can have a detrimental effect on the storage of the component. The arrangement of several bearings on top of each other is not permitted.
