Typical Density: 3-5 lb/ft³
Temperature Range: -40°F to +200°F
Flammability: UL94 V0 and UL94 HF-1

Applications typically include gaskets and seals in a variety of engine enclosures and equipment.

POLYTECH^® High-Density Polyurethane Foam Grade (PHU)

POLYTECH^® High-Density Polyurethane Foam Grade (PHU) is a low modulus open cell polyurethane foam. It behaves like a closed cell foam product when compressed and is an excellent gasket seal. This material has a significantly lower compression set than typical closed cell foam gaskets.

Typical Density: 15 lb/ft³
Temperature Range: -45°F to +212°F
Flammability: UL94 HBF; FMVSS302

Applications typically include gaskets and seals around equipment doors as well as mounting and protective pads.

POLYTECH^® Neoprene Blend Foam (PNB)

POLYTECH^® Neoprene Blend Foam (PNB) is a Neoprene/EPDM/SBR closed cell blend foam with good resistance to weather, oxidation, and ozone. This is an economical closed cell foam for a variety of uses.

Typical Density: 5-7 lb/ft³
Temperature Range: -70°F to +200°F
Flammability: UL94HF1

Applications typically include gaskets and seals in a variety of engine enclosures and equipment.

POLYDAMP^® Low Permeability Foam (LP-18)

POLYDAMP^® Low Permeability Foam (LP-18) is a soft, ether-based polyurethane foam with low permeability but quick recovery. It is an excellent low-cost alternative to traditional closed cell foams in applications where moisture and air need to be retained.
