Plastic & Rubber Magnet Series
Plastic & Rubber Magnet is a kind of soft
and elastic magnet. It is compound of rubber
(NBR or CPE) and ferrite power. It has the
following features
1: high magnetic property than normal
sintered isotropic ferrite
2: easy to design in various shapes such as
slicing, drilling and rolling
3: with density3.6-3.8g/cm3
4: easy processing for sizes and shapes
The magnetic strip seals are very stable and
have good elasticity, resistant to
demagnetization, weather, corrosion and
migration. The magnetic, flakes and strips
have smooth surfaces and high magnetism, are
best mated parts of toys, decoration and
magnetic health care products; can be used
in Export-Marketed toys and micro-motors and
others.
Magnetic strip is a permanent flexible magnetic
material available in strip and extrusion forms;
standard or custom manufactured to satisfy
specific processing requirements. Flexible
magnetic strips provide an alternative material
for printing, signage, holding, and fastening
applications.
Applications include latches or catches,
gaskets, door seals, tool holders, and holding
fixtures. For signs, charts, displays, shelf
labeling, and novelties, they are a reusable
alternative to adhesive or fasteners. They can
also be used in switches or sensing devices or
to dampen noise and vibration.
Magnetic strips come in various widths
ranging from 1/2 inch to 2 inches and
thicknesses ranging from 0.030 inches to 0.25
inches. They can be supplied in lengths of 50
feet or 100 feet coils. For easy mounting the
magnetic strips can be supplied with a pressure
sensitive adhesive backing or foam tape backing
on one side for more bonding strength. In some
applications these magnets are also provided
with steel backing to increase the holding
power. A common method of manufacturing magnetic
strips is by extrusion.
Extrusion: to produce materials in strip form
(from about 1/4" to 10" wide)
Calendering: to produce materials in sheet form
(up to about 24" wide)
Surface Treatments
No surface
treatments are
required to protect
against corrosion.
We are able to
laminate a variety
of decorative
facings to magnetic
strip, such as PVC(
white PVC, matte
white-PVC, and gloss
white-PVC and color
PVC, such as red,
yellow, black,
brown, etc), self
adhesive (standard
adhesive and 3M
adhesive), and UV.
Temperature Effects
Magnetic properties
of flexible magnets
degrade linearly
with temperature in
the same way as
Ceramic magnets.
However, the
limiting factor for
flexible magnets are
the binder materials
used to render them
flexible: these
begin to flow at
temperatures of
about 250
F.
Common Applications
for Flexible Magnets
Flexible magnets are
used in a variety of
applications from
labeling, holding,
door gaskets, and
signs, to
micromotors and CRT
focusing. Typical
applications:
crafts, toys, games,
magnetic signs,
displays, production
control (or visual
aid) systems,
warehouse shelf
labeling, door
gaskets, door and
cabinet closures,
small tool and
instrument holders,
movable markers,
advertising
premiums, magnetic
business cards,
architectural
planning layouts,
etc.
APPLICATIONS
Fridge Magnets,
Vehicle Signs,
Advertising Display,
Toys and Games,
Educational, Visual
Planning, Bin
Markers, Graphics,
Hand Lettering, Hot
Stamping,
Die-Cutting, and
much more.
MAGNETIC PERFORMANCE
Most of
Magnet
brand flexible
magnetic sheeting is
a isotropic grade of
ferrite having an
energy product
between 0.63 and
0.73 MGOe; flexible
magnetic sheeting
with
semi-anisotropic /
anisotropic grade of
ferrite are
available for more
specialized
application, which
provide higher
energy product
demand upon request.
