27# Rebonded Neoprene Foam
27# Rebonded Neoprene Foam is a controlled particle size composite of recycled cellular rubber and plastic foam with a density of 27.3 lb/ft³ and a compression deflection of 14 psi per ASTM D1056-07. It is the highest density rebonded neoprene in the series, engineered for maximum and very consistent compression deflection with low compression set. The material exhibits a split tear strength of 60 lb/in and elongation of 50%.

27# Rebonded Neoprene Foam is the highest density grade in the H-O Products rebonded neoprene foam series, built from controlled particle size composites of recycled neoprene, EPDM, and SBR cellular rubber and plastic foam. At 27.3 lb/ft³ and a compression deflection of 14 psi, this grade is specifically positioned for applications demanding maximum compression deflection and highly consistent load-bearing behavior.
It is suited for protective pads for separating, protecting, and stacking products, as well as glass separator pads, dust seals, sound isolation, and other cushioning and damping applications.
The very low water absorption without vacuum (1.8%) indicates excellent resistance to moisture ingress. Compression deflection change after oven aging is controlled to ±10% after 168 hours at 158°F over 7 days per ASTM D1056, confirming dimensional stability under thermal aging conditions. The combination of high density, very consistent compression, and low compression set makes this grade the preferred choice when maximum load resistance and long-term recovery are required.
No compliance standards are specified on the manufacturer’s TDS for this material.
What differentiates 27# Rebonded Neoprene Foam from the 25# Rebonded Neoprene Foam?
27# Rebonded Neoprene Foam is the highest density grade in the rebonded neoprene series at 27.3 lb/ft³, with a measured compression deflection of 14 psi — the maximum in the series. The TDS specifically highlights very consistent compression as a key feature, making this grade the preferred choice where repeatable, controlled load resistance is critical. The 25# grade offers lower density, RoHS compliance documentation, and is optimized for PSA compatibility and dynamic cushioning.
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 separator pads and dust seals held under long-term load, high compression set means the material permanently thins over time, reducing protective cushioning and seal integrity. The 27# Rebonded Neoprene Foam is described on the TDS as having low compression set, and its oven aging compression deflection change of ±10% confirms stable dimensional performance under thermal cycling.
What is the recommended service temperature range for 27# Rebonded Neoprene Foam?
No service temperature range is specified on the manufacturer's TDS for this material.
Is 27# Rebonded Neoprene Foam suitable for regulated environments?
No compliance standards are specified on the manufacturer's TDS for this material. Contact H-O Products for further regulatory information.
How should 27# Rebonded Neoprene Foam be specified?
Specify grade (27# Rebonded Neoprene Foam), thickness, color (Black), dimensional tolerances, and finished format.
