CLOSED CELL, EXTRUDED POLYETHYLENE FOAM CORD USED AS A SUPPORT FOR ELASTOMER SEALANTS TO GAUGE THE CORRECT SIZE OF FLEXIBLE JOINTS

 

Description

---

Mapefoam is a closed-cell, extruded polyethylene foam cord used as a back-up material for elastomeric sealants. Its smooth, anti-adhesive surface prevents bonding with the sealant, allowing the sealant to move freely and uniformly within the joint. Mapefoam is available in various diameters to suit different joint sizes.

 

Uses

---

Mapefoam is used to regulate the depth of sealant in expansion and distribution joints and to:

• Prevent adhesion of the sealant to the bottom of the joint

• Control the correct sealant depth

• Reduce sealant consumption

• Maintain optimum elastic performance of the joint

 

Characteristics & Advantages

---

• Expanded polyethylene cord: non-stick for subsequent elastic sealants and rot-proof over time

• Closed cell outer surface: no water absorption

• Easily compressible to promote self-support within the joint

• The most common diameters also available in small packages (bags of 10 linear metres)
