SO500 Series Low Density


Gaska Tape’s SO500 Series is a specifically formulated, super soft, semi open cell Polyvinyl Chloride foam that can be produced with or without adhesive on one side.

SO500 is formulated and manufactured for applications that require a very soft product with a very low force to compress.

This product has been specifically formulated to meet or exceed the Federal Motor Vehicle Safety Standard (FMVSS) 302A.


  • Seals out air, condensation, light and dust when compressed.
  • Provides cushioning, vibration dampening, and sound deadening.
  • Conforms to irregular surfaces and curves and can be used as a stuffer.
  • Alternative to low perm urethane and mechanically crushed rubber foams where longer product life is necessary.
  • High-tack acrylic adhesive has a wide temperature service range.
  • Used in conjunction with thin gauge plastics and sheet metal to prevent over-bowing or over-flexing.
  • Die or kiss cutting SO500 Series is available on 84# polycoated release paper or 12pt. release board.
  • Can be laminated to polyester film to provide dimensional stability.
  • Black color standard.
