Difference between Pro-Pad recycled rubber foam underlay and Rebond PU foam underlay

Underlay made of recycled material is common on the market, and rebond PU foam underlay is the most common option. Rebond PU foam underlay is made of PU foam chips, compressed to adhere together, and is often used in residential environments. Pro-Pad Underlay is made of PIR (post-industrial recycled) rubber foam chips that undergo the patented manufacturing process and then reform into a 3D-expanded structure. Different from the rebond PU underlay, the Pro-Pad underlay provides excellent cushioning and durability, and its material is hydro-resistant and will not absorb water. It brings a comfort and luxury underfoot feeling, and can be widely used in various applications such as industrial, commercial, and residential. This blog is going to compare the Pro-Pad underlay and the rebond PU underlay from multiple aspects:

- Manufacturing Process & Structure:
