Gasket Materials

Polymer Product Solutions

Polymer Technologies produces a number of unique and standard gasketing materials. We offer an extensive variety of options including Vinyl, Polyurethane, Neoprene, Blends, and Silicone Foam gaskets. When used in conjunction with our other energy control materials, our foam gaskets allow for increased efficiency by making sure unwanted energy does not escape from your product.

If you aren’t sure what kind of gasket fits your needs, our engineers can review your application options and then offer expert recommendations. If you bring us your complex issues, we will design a custom gasketing solution that meets your needs.

Our engineers will dissect your problems and develop an unparalleled solution.

Below is a sampling of our gasketing products for a variety of applications:

POLYTECH® Vinyl Nitrile Foam (PVN)

POLYTECH® Vinyl Nitrile (PVN) is a Vinyl/Nitrile/Neoprene closed cell foam designed for use as a gasket or seal in a variety of environments. It offers excellent resistance to gasoline and other aliphatic hydrocarbons.

  • 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.

POLYTECH® Cross Linked Polyethylene Foam (PCE)

POLYTECH® Cross Linked Polyethylene Foam (PCE) is a 2 lb/ft³ density cross-linked polyethylene closed cell foam.  It offers a smooth skin surface on both sides and a fine cell structure.

  • Typical Density: 2lb/ft³
  • Temperature Range: -110°F to +215°F
  • Flammability: FMVSS302; UL94 HF-1 version also available

Applications typically include gasketing and cushioning around equipment doors.

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.

  • Density: 2lb/ft³
  • Temperature Range: -40°F to +225°F
  • Meets impermeability tests – Ford B0112-03 and GM6068M

Applications typically include radiator seals and various gasketing applications within an engine environment.

POLYTECH® Silicone Foam grade 800 or 1000 (PSL)

POLYTECH® Silicone Foam grade 800 or 1000(PSL) is a soft cellular Silicone Foam that is extremely resilient to mechanical fatigue and has high compression set resistance.  It also has Excellent Flame Spread and Smoke Density values.

  • Density: 800 grade - 20lb/ft³; 1000 grade - 12lb/ft³
  • Temperature Range: -67°F to +392°F
  • Flammability: UL94 V0; UL94 HF-1

Applications typically include transportation, medical and other highly demanding applications.
