Quick Detail:
Description:
Heat shrink tubing (or, commonly, heat shrink or heatshrink) is a mechanically expanded
extruded plastic tube ordinarily made of nylon or polyolefin, which shrinks in one plane
only (its diameter) when heated, to between one-half and one-sixth of its diameter.
Heat shrink tubing is manufactured in a multitude of varieties and chemical makeups
with the exact composition of each type being dependent on the intended application.
From near microscopically-thin-wall tubing to rigid, heavy-wall tubing, each type
has precise design and chemical additives that make it suitable for meeting any of
a wide variety of environmental demands. Heat shrink tubing is rated by its
expansion ratio, a comparison of the differences in expansion and recovery rate.
Heat shrink is used to insulate wires, providing abrasion resistance and environmental
protection for stranded and solid wire conductors, connections, joints and terminals
in electrical engineering. It can also be used to repair the insulation on wires or to
bundle them together, to protect wires or small parts from minor abrasion, and to
create cable entry seals, offering environmental sealing protection.
Applications:
Different applications require different materials:
PTFE (fluoropolymer) tubes have a wide operating temperature range (-55 to 175 °C),
a low coefficient offriction, and high resistance to chemicals and punctures.
Viton, another fluoropolymer with high chemical resistance, is widely used in hydraulic equipment.
It is highlyflexible, with a very wide operating temperature range of -55 to 220 °C,
making it suitable for protecting sensitive devices against heat.
Polyvinylidene fluoride (PVDF) tubes are intended for high temperature applications.
Fluorinated ethylene propylene (FEP) is a lower-cost alternative to PTFE.
Elastomeric tubes maintain high flexibility even at low temperatures and
meet stringent international specifications. Their operating temperature range is -75 to 150°C.
The material is resistant to many chemicals (including diesel and petrol)
and has good resistance to abrasion, even in severe environmentalconditions.
A common shrink ratio is 2:1
Silicone rubber offers excellent resistance to scrape abrasion and high flexibility.
Their operating temperature range is -50 to 200°C[citation needed]
Polyolefin tubes, the most common kind, have maximum continuous-use temperatures
from -55 to 135 °C, and are used by the military, aerospace and railway industries.
They are flexible and fastshrinking, and manufactured in a wide rangeof colors (including clear),
which can be used for color-coding wires.With the exception of black,
they tend to have lower resistance to ultraviolet light;
accordingly, only black is recommended for outdoor applications.
A common shrink ratio is 2:1, but highgrade polyolefin heat
shrink is also available with a 3:1 ratio.
PVC tubes are available in several colors and can be used outdoors.[citation needed]
