STYLE 24B
Expanded PTFE Joint Sealant

 
CONSTRUCTION
Style 24B joint sealant is produced by expanding 100% virgin PTFE into a highly fibrillated structure which exhibits characteristics significantly different than conventional PTFE. The expanded PTFE is much more flexible than regular PTFE and thus conforms easily to irregular and rough surfaces. In addition, the expanded material is easier to compress and exhibits excellent resistance to creep and cold flow. This style of joint sealant is supplied as a continuous tape with a self-adhesive backing strip to facilitate easy installation.

APPLICATION / SERVICE
Style 24B joint sealant is soft and marshmallow-like, allowing it to readily conform to and seal flanges with irregular and damaged surfaces. Because it is composed of 100% PTFE, it can handle virtually all chemicals in the 0 - 14 pH range and will not contaminate flow media. It has no smell or taste. It is neither contaminating nor toxic and it fulfills the FDA 21 CFR 177.1550 Perfluorocarbon Regulations.

The versatility of this style is finding new applications everyday in the process industries and the OEM market.

This style is recommended for the following sealing applications:


 
  • Steel pipe flanges
  • Heat exchanges
  • Manhole and handhole covers
  • Glass-lined pipe flanges
  • Fiber glass reinforced vessels
  • Ceramic joints
  • Fiber glass pipe flanges
  • Pump housing flanges
  • Ventilation ducts
  • Plastic pipe flanges
  • Compressor housing flanges
  • Hydraulic and pneumatic systems
  • Fume ducts
  • Turbine cases
  • Water supply systems
  • Concrete lids
  •
