This specification defines the requirements of continuous cast and slab (or bun) stock cellular polyurethane materials based on polyether or polyester chemistry to be used as air, dust, light, and water seals or gaskets. These materials may also be used as isolators, rattle protection, covers for gaps and other suitable applications. These materials are typically die cut or slit to width from sheet stock or skived from bun stock, and may have pressure sensitive adhesive applied to one or both sides.

For molded, cast, and slab polyurethane foam for sound absorbing applications refer to GMW14196: Polyurethane Foams for Acoustic Applications. For elastomer polyurethane foams for sealing and vibration handling applications having a minimum of 15% bio-renewable and a minimum of 25% post automotive shredder residue, refer to GMW16515: Flexible Expanded Material for Air, Dust, Water Sealing and Noise Vibration Handling Applications. For slab/sheet polyurethane foam for Engine Compartment Sound Absorber (ESCA), refer to GMW16869. 

Material Description.

All types of foams described in this specification are polyurethane open cell foam based on polyether or polyester chemistry. 

Symbols.

Not applicable.

Applicability.

The polyurethane material specified in this standard is recommended for use as follows. • Gasket for vibration damping and vibration and shock insulation. • Air, dust, water seal and/or light seals.

• Squeak and rattle applications.

• Seal and gasket applications.

• Energy absorber and interior trim applications. This specification segments these polyurethane materials into three types. The three (3) types are based on material performance and product application, and the types do not address the actual part design. These standards are to be considered minimum compliance.

Remarks.

Recycled or Alternate Materials. Recycled polyurethane materials or bio-based materials may be used for parts under this specification
