ptfe, 25% glass filled slide plate


Standard Assembly: 2 units of 3/32" PTFE, 25% glass filled, bonded to 1/8" carbon steel. For field tack welding. 1/2" lip. Loads to 2000 PSI, Temperature: -320°F to +500°F

Full Weld Assembly:
2 units of 3/32" PTFE, 25% glass filled, bonded to indicated backing material with 1/2" lip all around for full welding. Loads to 2000 PSI, Temperature: -320°F to +500°F

PART # - PTP -- 3/32" TFE -- 10 Ga. SS -- 1/2" LIP AND SIZE


  • Ease of installation.
  • No setting problems.
  • Low coefficient of friction
  • No surface treatments, grouting, or expensive
    mechanical attachment necessary.
  • Chemically inert.
  • Unaffected by weather conditions.
  • Ability to absorb dirt and grit within itself.
  • Self-aligning when used in conjunction with
    elastomeric backing pads.

1. Please specify the dimensions of the upper plate and dimensions of the lower plate. It is common practice that the upper plate is generally larger than the lower plate.
2. Specify lip dimension (if different than the standard 1/2").
3. Specify base plate thickness (if different than standard 1/8").


Prior to Welding: Locate the slide plate base in the appropriate position on the existing steel surface. Place a protective covering on the PTFE, 25% glass filled. Where seal welding is not required, follow the diagram shown which indicates 1/8” thick fillet weld, 1” long every 4” around entire perimeter of the base. For welding, use GMAW 0.035 wire or SMAW 3/32" stick.

Where full seal welding is required, use a similar pattern of welding until a full weld is obtained. This method will prevent damage to the PTFE, 25% glass filled. (A full weld will help prevent seepage of water between the slide bearing plate and the support structure.) Avoid overheating, which may destroy the bonding of the PTFE, 25% glass filled to the base plate.

Installation in Concrete: Secure the top and bottom elements together with paper adhesive tape. Then attach the bottom element anchor bolts with wire to the form. After the bottom pour is made, repeat on top element. During the first expansive cycle, the tape will break.
