Our neoprene sponge originates as large sponge blocks, which we precision-cut into sheets ranging from 0.8mm to 10mm thickness – these are what we commonly refer to as “Neoprene Sheets”.
The surface of “Sponge Block” is called “Smooth Skin”, and the middle of “Sponge Block” is called “Cell”. The “Skin” is stronger than the “Cell”, but the elasticity is slightly worse.
Neoprene Smooth Skin
Neoprene Skin refers to the outer layer of a neoprene sponge block, with one side being the smooth/hard surface and the other side bonded to the cellular core (“cell”).
It offers superior strength and surface smoothness, though with slightly reduced elasticity compared to the pure cell material.
Key Applications:
Smooth Skin (CR Neoprene): Ideal for wetsuits (triathlon, spearfishing), swim caps, and other products requiring flexibility + durability.
Hard Skin (SCR/SBR Neoprene): Used in high-strength applications where rigidity and abrasion resistance are critical.
Neoprene Cell
Neoprene Cell refers to the core material of neoprene sponge, with cellular structure on both sides.
It offers superior elasticity and softness compared to skin-layer materials, making it ideal for applications requiring maximum flexibility.
Key Features: Uniform cellular structure throughout Excellent compression recovery Lightweight and flexible
Common Applications: Protective padding & cushioning Seals and gaskets Sports equipment lining Industrial vibration damping
