Bakelite Composites

Also known as Formica, Tuffnol, and Novasteen, bakelite composites are insulating laminates. These products are most often used for switchboards and electrical functions.

There are three main types. Some of these types are available in varying grades:

Paper Bakelite:

Laminated material made from layers of compressed paper sheets. These paper sheets are bonded with a thermosetting synthetic resin.

There are 4 grades of paper bakelite, based on their electrical traits.

• P1: Displays great mechanical and ample electrical properties

• Cold Punching Grade – P1: Features great mechanical and capable mechanical properties, and can be cold punched (20-25°C).
P1 & P2 is good for no-humid and low-tension uses, such as:

  • Control panels
  • General insulation panels
  • Transformer and choke bobbins
  • Condenser mountings
  • Tubelight ends and chokes• P2: Features good mechanical and electrical properties. Specially suited for power electrical industry for use in oil. Common uses consist of:
  • Distribution boards
  • Fuse holder base
  • Transformer covers
  • C.B. handles and side frames• P3: Features decent mechanical and good electrical properties. In addition, P3  presents low water absorption. This product is good for higher voltage and high-tension applications, even under tropical conditions, such as:
  • Grid covers
  • Relay spacers
  • Selector bank insulation
  • Transformer and choke bobbins for power – electronics
  • HV transformer tap chargers

Fabric Bakelite:

Laminated material made from layers of compressed woven cotton fabric. These layers of fabric are then bonded with a thermosetting synthetic resin. There are 2 grades, based on the coarseness of cloth.

F1: Fine weave grade has excellent mechanical strength, and is very easy to machine. This item also has a very good strength-to-weight ratio. Some uses include:

  • Shuttles
  • Pulleys
  • Structural parts
  • Machine tool gibs/slideways
  • Friction plates
  • Gears
  • Automobile couplings
  • Spindles
  • Low-voltage contact breaker• F3: This is a general purpose grade product. F3 offers good mechanical strength, as well as high impact resistance. In addition, this product can be machined quite easily. Some uses are:
  • Heavy duty gears
  • Piling dolly
  • Rolling mill bearings
  • Pulleys
  • Workbench tops.

Switchpanel: A paper based phenolic laminate insulating panel. You will find it is great for use in:

  • Domestic and industrial metering panels
  • Switchboard insulating panels and supports.
