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 is an alternative to low perm urethane and mechanically crushed rubber foam where longer product life is necessary.


  • Low compression with limited sealing ability.
  • Provides cushioning, vibration dampening, and sound deadening.
  • Conforms to irregular surfaces and curves and can be used as a stuffer.
  • Used in conjunction with thin gauge plastics and sheet metal to prevent over-bowing or over-flexing.
  • High-tack acrylic adhesive has a wide temperature service range.
  • SO500 Series is a self -extinguishing formulation and meets FMVSS 302A
  • SO510 is available on 84# polycoated release paper, 12pt release board, or laminated to polyester film to provide dimensional stability.
  • Specifically formulated to meet automotive specifications-see Gaska Tape Automotive Products on our website.
  • Black color standard, other colors available upon request.
  • Sulfur-Free
