Summary of information:

PTFE graphite plate or Teflon graphite plate, graphite modified PTFE plate, and PTFE blackboard are formed by mixing suspended PTFE resin and filler graphite evenly, forming and sintering. Adding graphite as a filling material makes the processed product have better lubricity and thermal conductivity, and improves the performance of PTFE such as pressure resistance, wear resistance, cold flow resistance, heat resistance, and dimensional stability. The appearance of PTFE-filled graphite plate is black, the surface is smooth, and defects such as cracks, delamination, and air bubbles are not allowed to affect the use. The density of graphite material is 2.0g/cm³ and the density of polytetrafluoroethylene is 2.1~2.3g/cm³ which is relatively close, so the density value of the mixed material does not change much.

Production steps of PTFE graphite sheet

1. Graphite and polytetrafluoroethylene resin are fully mixed by a mixer to form a polytetrafluoroethylene-filled graphite mixture, which is sent to the molding workshop, and the powder is weighed according to the specifications and sizes required by the process.

2. Mix PTFE filled graphite into the mold. Due to the poor fluidity of the mixture, uniform paving is a very important step to ensure uniform thickness of the finished graphite plate.

3. Use a press with a certain tonnage to mold the mixture, which is a molding process.

4. The raw board is formed. After forming, the raw board needs to be sent to the oven for heating.

5. Enter the sintering furnace (oven) for sintering, heating, heat preservation and cooling.

6. Scrub the PTFE graphite plate. In this way, the graphite filler is added to the PTFE, so that the wear resistance of the plate is more than three times that of the pure PTFE plate, the hardness is also greatly improved, and the compressive strength is also improved. greatly improved. The specifications of PTFE graphite sheets can be customized, processed or cut according to customer needs. Mainly used in chemical industry, petroleum, construction, electromechanical and other industries, such as: pipeline support friction liner, backing plate, slide plate, seal, etc.

7. If you need to make graphite PTFE tubes or rods, you can use the same process for molding and sintering as long as you use the mold of the corresponding specification.
