Polyethylene foam, also known as PE foam, is one of the most popular polymers. Its many qualities make it perfect for a wide range of applications. Everyone knows that PE foam is used as packaging material. It protects fragile and expensive items from being damaged while in transit. It is also no secret that PE foam is used to manufacture pool noodles, the world's most popular pool toy. Did you know that PE foam is also used for manufacturing backer rods? These flexible and versatile rods are used to fill gaps and cracks in buildings. They are used by contractors and engineers for a wide range of sealing applications. This blog lists three reasons that make PE foam perfect for manufacturing backer rods.

 

3 Reasons PE Foam Is Perfect For Manufacturing Backer Rods

 

Lightweight

 
Backer rods need to be light and this is one of the reasons polyethylene foam is a perfect choice. Heavier materials are not ideal for sealing applications. What's more? PE Foam is also pliable, allowing it to be manufactured and cut in different sizes. The light weight of PE foam is in no way an indicator of its durability. PE foam is an extremely durable polymer, making it perfect for manufacturing soft rods.
 

Compression Ability

 
Backer rods are used as backing materials before applying sealants. They need to be able to fit in tight and confined spaces and fill them. The compressions and recovery ability of PE foam make it easy for backer rods to be squeezed into tight spaces. Once the soft rod is squeezed in, it recovers and fills the gap. This helps reduce the need for sealant, helping save money.
 

Water & Moisture Resistance

 
They play a huge role in maintaining the structural integrity of backer rods. Since PE foam is water and moisture-resistant, it is perfect for manufacturing soft rods. This resistance prolongs the lifespan of the backer rod by preventing degradation caused by environmental factors.
