Cold Shrink Plastic Supporting Core For Rubber Tube Expansion, Tool Handle & Bicycle Grip
The Cold Shrink Plastic Supporting Core is a high-performance internal support component engineered specifically for cold shrink installation applications. This Plastic Supporting Core serves as a temporary structural support that maintains rubber tubes, tool handles, and bicycle grips in an expanded state during installation. After the outer material is properly positioned, the Plastic Supporting Core is easily removed, allowing the rubber to contract tightly around the target object at room temperature without any heat application. The Cold Shrink Plastic Supporting Core is widely recognized for its reliability, ease of use, and superior performance across multiple industries including power, telecommunications, tool manufacturing, and bicycle manufacturing.
The Cold Shrink Plastic Supporting Core is designed to meet the demanding requirements of various industries:
Power Industry – The Plastic Supporting Core is used for rubber tube expansion support in cable joints, terminations, and insulation protection applications.
Telecom Industry – This Plastic Supporting Core provides internal support for cold shrink tubing used in antenna sealing, cable splices, and fiber optic protection.
Bicycle Industry – This it functions as an internal support core for bicycle grips, ensuring stability and comfort during use.
Other Industries – The Plastic Supporting Core can be applied in general industrial applications requiring internal support for rubber or plastic hoses.
1. Excellent support strength and toughness – The Plastic Supporting Core ensures reliable structural support during cable installation without breakage or deformation.
2.Good low temperature brittleness – It can be installed in Arctic regions without cracking or breaking under extreme cold conditions.
3.Good high temperature resistance –It maintains its shape and performance in hot regions without deformation.
4.Superior tensile and compression strength – It resists pulling and pressing forces, ensuring long service life even under demanding conditions.
5.Excellent corrosion and biological erosion resistance – This Plastic Supporting Core withstands harsh environments, making it suitable for outdoor, underground, and high-humidity applications.
6.Compliant with RoHS 2.0 standard – It meets environmental safety requirements for restricted substances.
7.Strict quality control – Every Plastic Supporting Core is manufactured using fresh raw materials under strict quality control to ensure reliable and consistent quality.

Q1:
What
is
a
Cold
Shrink
Plastic
Supporting
Core?
A:
It
is
a
temporary
internal
support
core
used
in
cold
shrink
installations.
The Plastic
Supporting
Core holds
rubber
tubes
or
handles
in
an
expanded
state
during
installation.
After
positioning,
the Plastic
Supporting
Core is
removed,
allowing
the
rubber
to
shrink
tightly
around
the
cable,
tool
handle,
or
bicycle
handlebar
without
heat.
Q2:
How
is
this
product
different
from
heat
shrink
products?
A:
Unlike
heat
shrink
products
that
require
a
heat
source,
the Cold
Shrink
Plastic
Supporting
Core enables
installation
at
room
temperature.
This
allows
for
safe,
tool-free
installation
in
environments
where
heat
is
not
available
or
not
recommended,
such
as
explosive
areas
or
outdoor
settings.
Q3:
What
industries
commonly
use
this
Plastic
Supporting
Core?
A:
This Plastic
Supporting
Core is
widely
used
in
the
power
industry,
telecommunications
industry,
tool
manufacturing,
and
bicycle
manufacturing
for
applications
such
as
cable
joint
protection,
antenna
sealing,
ergonomic
tool
handles,
and
bicycle
grips.
Q4:
Can
the
size
of
the
Plastic
Supporting
Core
be
customized?
A:
Yes,
we
offer
customization
of
the Plastic
Supporting
Core in
terms
of
diameter,
length,
and
wall
thickness
to
meet
specific
application
needs.
Please
contact
us
with
your
specifications.
Q5:
Is
this
Plastic
Supporting
Core
resistant
to
harsh
environments?
A:
Yes.
The Plastic
Supporting
Core
offers
excellent
corrosion
resistance
and
resistance
to
biological
erosion,
making
it
suitable
for
outdoor,
underground,
and
high-humidity
environments.
