Expanded PTFE Joint Sealant 24B

Construction

Style 24B joint sealant is produced by expanding 100% virgin PTF 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 materials 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

Style 24B joint sealant is is soft and marshmallow-like, allowing it to readily conform 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 fulfills FDA 21 CFR 177.1550 Perfluorocarbon Regulations.

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

This style is recommended for the following sealing applications:

• Stelle pipe flanges
• Glass-lined piped flanges
• Fiberglass pipe flanges
• Plastic pipe flanges
• Fume ducts
• Concrete lids
• Heat exchanges
• Fiberglass reinforced vessels
• Pump housing flanges
• Compressor housing flanges
• Turbine cases
• Manhole and handhole covers
• Ceramic joints
• Ventilation ducts
• Hydraulic and pneumatic systems
• Eater supply systems
