Tufnol
Phenolic paper grades are strong, rigid
and very economical. They have good electrical insulating
properties and they are used in a wide range of electrical
installations, in equipment where rigid electrical insulation material
is required. The higher specification grades are chosen
for higher voltage and for greater electrical stability
in conditions of varying humidity.
The
impact strength of phenolic paper grades is not as high
as materials in other groups and they are not usually
chosen where toughness, bearing properties or high stress
carrying capabilities are required. However, the lowest
cost grades in this group represent excellent value
as rigid non-metallic materials and they are used in
a very wide range of less demanding applications.
Typically, there are 3 brands within this group of Tufnol:- Heron, Kite and Swan.

Kite
Brand
Good
quality general purpose electrical insulation grade
- First
class electrical insulating material with good dielectric
strength
- High
insulation resistance
- Low
moisture absorption and good mechanical strength
- Kite
Brand sheet meets British Standard BS EN ISO 60893
Type PF CP 206
-
It is readily machined and can be hot punched up to
a thickness of 3.2mm
Kite
Brand is the most widely used of all phenolic paper
grades, wherever a good quality general purpose electrical
insulation material is required. It is used for a multitude
of different applications at low, medium and high voltages,
including such items as terminal boards, mounting panels,
tag strips, coil farmers, insulating sleeves and bushes,
busbar supports, tool and instrument handles, coil supports,
insulated enclosures, brush holders, insulating spacers
and special purpose plugs and sockets.
Tufnol
Grade 1P/13
Low cost
commercial grade
- Low
cost commercial paper based laminate where
electrical requirements are moderate
- This
grade has a higher mechanical strength than the other
grades in our phenolic paper range and greater impact
strength
- It
can be machined readily and components can be hot
punched in thickness up to 3.2mm
This
material is used for many electrical components where
low voltage insulation is required. In addition, the
low cost and all round properties of Tufnol Grade 1P/13,
make it a popular choice for many less-demanding mechanical
duties. Consequently, it is used for a multitude of
different engineering parts, such as spacers, base plates,
side plates and simple jigs and fixtures, in addition
to the usual range of electrical insulation components.

Heron
Brand
High
specification phenolic paper laminate
- Characteristics
equivalent to Kite Brand, but with improved performance
in high humidity meeting BS EN 6089 Type PF CP 204
- First
class electrical insulating material with very low
moisture absorption
-
Especially suitable for use in humid or tropical environments,
where its electrical properties are retained to a
high degree
- Excellent
electric strength
- Very
high insulation resistance after immersion in water
and is
- Designed
to meet the highest electrical standard for phenolic
paper materials in BS and IEC specifications
- It
machines well and can be hot punched up to a thickness
of 3.2mm
Heron
Brand is used in electrical applications where high
insulation performance is required, with stable properties
in a moist or humid environment. Items such as terminal
boards, mounting plates, cover plates and insulating
spacers have frequently been made. This grade has been
largely superseded by the use of epoxy and other materials
in such applications and is retained in our range for
instances where it is needed for particular specification
requirements.
Tufnol
Grade 2P/20
- A good
quality electrical insulation material for punched
parts
- specially
formulated punching grade with properties similar
to those of Kite Brand Tufnol
- It meets
BS EN 60893-3-4 Type PF CP 206 and has excellent electrical
insulation properties
- It may
be heated up to a maximum temperature of 80oC for
punching where required to produce an intricate profile.
Lower temperatures will give satisfactory results
for more simple shapes
Grade
2P/20 is used where punched parts are required from
a good quality, rigid insulation material. A wide range
of small electrical components are made from this material,
including tag strips, mounting boards, component holders,
switch operating arms, insulating washers, plug bases
and back plates.
Tufnol
Grade 1P/24
A
flame retardant paper based grade, specially formulated
to give low smoke output and low smoke toxicity. Electrical
properties similar to Kite Brand.
- Electrical
qualities similar to Kite Brand but with the additional
features of improved fire properties
- Grade
1P/24 is manufactured with a specially formulated
phenolic resin, which provides flame retardant properties
combined with much reduced smoke output in a fire
- Good
electrical insulating material meeting the requirements
of BS 2572 Type P3 and it also meets Class FV0 flammability
in the BS 6334 (IEC 707) test
- In
addition, it achieves Class 1 performance in the BS
476 Part 7 ‘Surface spread of flame’ test
Tufnol
Grade 1P/24 is used in electrical applications where
a high quality electrical insulating sheet is required
with the additional protection of improved fire properties.
Many conventional insulation applications would benefit
from the use of flame retardant materials and the low
smoke and good spread of flame performance offered by
Grade 1P/24 is of particular importance in areas where
escape from fire may be restricted. It can be used for
items such as terminal boards, mounting plates, busbars
and cable supports in railway applications, ships and
ferries and a wide range of underground and restricted
access areas.

Tufnol
Grade 1P/21
A medium specification electrical grade meeting BS EN
60893 Type PF CP 203 requirements.
- This
grade is intermediate in its electrical performance
between the high electrical specification of Kite
Brand TUFNOL and the low cost Grade 1P/13
- An intermediate
commercial paper grade
- Produced
to meet British Standard BS EN 60893-3-4 Type PF CP
203
-
Water absorption and mechanical performance are also
in the range between these two other grades.
- It
is readily machined into components and can be hot
punched, to produce items in of thickness up to 3.2mm
This
material is usually selected where electrical performance
slightly above that of a basic commercial paper grade
is required, with a minimum effect on cost. It is used
for a wide range of electrical items, such as terminal
boards, mounting panels and tag strips.
Swan
Brand

similar to Kite Brand. Available in solid moulded sections
to complement the Kite Brand range of sheet and hollow
moulded sections.
- Swan Brand is a good quality electrical
insulating grade, similar in performance to Kite Brand
- Produced
to complement the Kite Brand range of sheet
This grade is used wherever a rod, bar or other solid
moulded section of paper based laminate is required.
Items such as insulated end caps, turned spacers, mounting
posts, electrode supports and insulated conveyor hanger
posts often require a round rod section. Also, Swan
Brand rectangular moulded bar may be preferred for certain
components, such as mounting blocks, where tapped holes
are drilled in several different directions.
