Eva Foam Applications

Applications

Polymer has been one of the most important materials in human society, with its synthesis technology that had been developed since the early 19th Century. Polymers are used in many applications, which influence every aspect of our lives.

What are Backer Rods and How are they Used?

When there are joints between tiles or other components/units of construction material, backer rods are used to fill up the vacant space. Similar to cylinder shaped foam rods, they are also available as flexible cords, sheets and planks. The builders first place these rods in grooves or cracks that cause the empty space and then firm them up with mortar, adhesive sealants or chinking.

Backer rods provide many useful features:

  1. Firmness
  2. Resistance to wear and tear
  3. Sturdiness
  4. Decoration
  5. Insulation from air, water, heat, dust and chemicals
  6. Save time and money

What are Fillerboard and How are they Used?

Concrete expands and contracts according to temperature changes and therefore some type of filler is needed between slab work to keep the concrete from buckling when it expands and to fill the resultant gaps when the concrete contracts.

Expansion (movement) joints may be used between the slabs and also to separate the slabs from structures, thereby preventing damage that may occur during these expansion and contraction cycles.

Filler broad provide many useful features:

  1. Good thermal insulation properties
  2. Natural bond breaker
  3. Easy to install
  4. Light weight
  5. Non-absorbent and non-tainting
  6. Bitumen free and rot proof, ideal for water retaining structures

Backer rods come in two types – open-cell and closed-cell.

These two varieties can be used either separately or together depending on the need. Open-cell rods are relatively less thick allowing more air circulation while the closed-cell variety pack more density. Being more pliant due to their softness, open-cell rods are easy to install than closed-cell ones. Open-cell rods are preferred for indoor purposes with lesser dampness while the closed-cell type is favored for outdoor purposes like platforms, courtyards and passageways.

Backer rods vary from a quarter inch to four inches or more in diameter. They are either made to order or sold in pre-determined sizes. Different construction requirements warrant different types and dimensions of these rods. They come in polyethylene and polyurethane forms.

Here are the common uses of backer rods:

  • Laying floors/tiles
  • Ornamental wall paneling
  • Sealing  and glazing doors/windows
  • Stoneware

Advantages of using backer rods:

  • Cheaper and time-saving replacement for costlier caulking compounds
  • Enable hour-glass shaped filling enabling sealants to manage unavoidable joint movements better
  • Being a bond-breaker, backer rods are non-adhesive to cold-applied sealants thereby preventing three-sided adhesion of joints
  • Control and enhances sealant usage
  • Repels moisture and reduces air leakage

It may appear that the role backer rods play is trivial or insignificant, but they are indispensable to builders in ensuring that the seals in joints perform well.
