25# Rebonded Neoprene Foam is a flexible, re-processed composite foam made from controlled particle size blends of neoprene, EPDM, and SBR recycled cellular rubber and plastic foam. Produced primarily from in-house raw materials, this grade delivers low compression set and excellent dynamic cushioning in a cost-effective format. It is designed for use as protective pads for separating, protecting, and stacking products, and is well suited for glass separator pads, dust seals, sound isolation, and general cushioning and damping applications.
The absence of processing additives that could interfere with adhesive bonding makes 25# Rebonded Neoprene Foam compatible with low-cost pressure-sensitive adhesive systems, simplifying converted part construction. The material demonstrates low compression deflection change after oven aging (7% after 168 hours at 158°F per ASTM D1056) and very low water absorption without vacuum (2.8%), reflecting stable performance under thermal and moisture exposure conditions.
Compliant with RoHS.
What differentiates 25# Rebonded Neoprene Foam from the 27# Rebonded Neoprene Foam?
25# Rebonded Neoprene Foam has a lower density (25.15 lb/ft³) than the 27# grade (27.3 lb/ft³) and is distinguished by its RoHS compliance, Black/Mixed color, and the absence of bonding-inhibiting additives that allow direct use with low-cost PSA systems. The 27# grade is positioned as the highest density rebonded neoprene for maximum compression deflection (14 psi), whereas the 25# grade provides excellent dynamic cushioning with greater flexibility in adhesive system selection.
Why is compression set critical for a rebonded foam used in cushioning and sealing applications?
Compression set measures the permanent deformation a foam retains after sustained compression. For cushioning pads and dust seals that are repeatedly compressed or held under load, a high compression set means the material will permanently thin over time, reducing its protective and sealing effectiveness. The 25# Rebonded Neoprene Foam is described on the TDS as having low compression set, supporting long-term performance in dynamic cushioning applications.
What is the recommended service temperature range for 25# Rebonded Neoprene Foam?
No service temperature range is specified on the manufacturer's TDS for this material.
Is 25# Rebonded Neoprene Foam suitable for regulated environments?
Yes. 25# Rebonded Neoprene Foam is fully RoHS compliant as stated on the TDS. No additional compliance standards are specified.
How should 25# Rebonded Neoprene Foam be specified?
Specify grade (25# Rebonded Neoprene Foam), thickness, color (Black/Mixed), compliance requirements (RoHS), dimensional tolerances, and finished format.
