MAXCEL®
POLYETHYLENE FOAM JOINT BACKING

Description

MAXCEL is a closed cell, circular polyethylene foam profile obtained by continuous extrusion.

Uses

MAXCEL is used as backing and depth control filler for expansion or waterproof joints which will be later sealed, between the same or different construction materials.
Under the present state of construction techniques, DIN 18540 standard determines the requirements which joint sealing materials must fulfill. This standard specifies that joint backing materials must have a convex surface. The material must not be hygroscopic, which is why it is adviseable that they be closed cell materials. Also, backing materials should not interfere in any way with the changes in shape of the sealing materials.

Advantages

- Easy to work with because of their low weight.
- Adequate compression resistance allowing good application of the sealing material.
- No water absorption because of its closed cell structure.
- Its higher density superficial layer provides the profile with good mechanical resistances, not hindering its workability.
- Especially appropiate as backing for joints to be sealed with silicones, polysulphides, polyurethanes. polyacrylates, etc.
- In the joints constructed with MAXCEL, the lack of adhesion of the sealing material to the polyethylene makes the stress at the joint appear exclusively perpendicular to the joint, with no stress on the backing.

Application

The application of MAXCEL profiles is very simple. The diameter of the section will be chosen keeping in mind that they should be compresed around 25 %, so that once placed in the joint, they are fixed perfectly and do not move when the sealing material is applied.

Cautions

- Do not place MAXCEL using sharp tools which could damage the surface.
- Do not use on MAXCEL sealing materials at temperatures above 70° C, such as molten bituminous fillers.
