Joint bottom or closed cell extruded polyethylene foam cord, to support the elastomeric sealants and achieve the correct size of the joints. Specially designed for application as a depth limiter in all types of sealing and cold expansion joints (up to + 90ºC **).

Joint depth limiter that can be used indoors and outdoors, for both horizontal and vertical joints.

Polyethylene foam profiles for joint filling suitable for correctly dimensioning the joint section of industrial, ceramic and natural stone floorings before filling with elastomeric sealants.
It can also be used to size the joints between precast panels, between anchors and supporting structure, etc.

General Properties

  • It consists of closed-cell expended polyethylene. It does not absorb water and retains its properties unchanged over time.
  • It has elasticity that makes it an optimal support for sealants.
  • Its non-stick surface allows the natural movement of the sealant.
  • Being the PE base material, it is an inert product with high chemical resistance.
  • Compatible with all kinds of sealing putties.
  • Environmentally friendly product: free of CFCs, HCFCs and chemical foams.
  • 100% recyclable.
  • Flexible, lightweight material, easy to install.
  • Its fine cellular structure and closed cells gives it an excellent barrier effect, no water absorption.

Presentation

Compressible closed cell circular polyethylene foam cord Density: 0.025 kg / liter (apparent)

Durability

Excellent

Applications

The polyethylene foam cord is suitable as a sealing support in expansion joints.

Advantage

  • Easily compressible.
  • Low transfer of loads.
  • Excellent recovery after tablet.
  • Provides a convex surface, which produces the optimal form factor for elastomeric sealants.
  • Sealant support / bond breaker strip / seal form factor.

Application mode

  1. Before placing the cord, it must be verified that the inside of the joint, all its depth, is clean and free of dirt and other elements; use of a nozzle vacuum is recommended.
  2. The cord will be inserted by light pressure on the inside of the joint at the intended depth. It is recommended to always use a diameter greater than the width of the joint to be sealed. For example, for a 12mm wide joint, a 15mm bead should be used.
  3. Fill the joint with the appropriate sealant.

Important: The dimensioning of the joint, its width and depth must be defined according to the expected movements, the elastic modulus of the sealant and the use for which it will be used.
