There is no fabric or texture in the neoprene rubber on the “plain” side—just raw rubber. White neoprene rubber may yellow over time even with fabric over it.
Perforated neoprene is ideal for medical braces and other body applications that call for breathable material. Only the rubber itself is perforated. The nylon or polyester fabric you choose is not perforated.
This neoprene has a surface texture much smoother than the plain. It’s commonly used in clothing and wetsuits. Smooth is only available in grade 2 (cr).
Textured neoprene has a rougher surface on the plain rubber side, allowing it to maintain better contact with the surface that it is placed upon.
Polyester covered neoprene will generally hold up better in direct sunlight than nylon will. Print on polyester if you wish to use an “ink jet” or dye-sublimation printing process that sprays ink into the fabric. A polyester fabric surface will hold the image much better and more clearly than nylon. Since the color of the fabric will influence the color of the ink used, we recommend using a White Polyester Fabric to make sure the final colors are true to what you need.
Nylon fabrics tend to fade in sunlight while polyester fabric doesn’t. Nylon is suitable for silk-screen printing. Since the designs will be on top of the fabric surface, any color of fabric will work well for this kind of printing. Nylon fabric has a stretch of longitude 95.56%, latitude 244.75%.
A fuzzy loop fabric applied to neoprene perfect for hook side of Velcro to bond with. U-loop should be used in Velcro applications that are not separated frequently, since u-loop will wear out. U-loop increases airflow for close-to-skin applications when facing skin.
A higher quality version of the U-loop. It stands for “UnBreakable Loop.” UBL should be used when Velcro will be frequently applied and removed. Textured on one side.
Peel/Stick Adhesive Backing:
This is an adhesive backing applied to the neoprene. Simply peel away the paper exposing the adhesive.
