Polyolefin

This is the most popular heat shrink tubing material. It is available in irradiated, flame retardant, and semi-rigid versions to meet the needs of different applications.

· Extremely flexible (semi-rigid tubing is less flexible but great for strain relief)

· Chemical and solvent resistance

· Low shrink temperature

· Fast recovery time

2.Elastic polyolefin

Heat shrink tubing made from polyolefin elastomers is designed to provide excellent physical properties to optimize processing and end-user outcomes.

· Rugged and mechanically strong

· Withstands heat, fluids, and physical abuse over time

· Low temperature flexibility

3.Adhesive polyolefin

This special polyolefin tubing is designed with a layer of adhesive that melts and flows when the heat shrink tubing is heated, creating a tight seal around the component.

· Excellent resistance to corrosion, abrasion, heat, and chemicals

· Very flexible

· Tight seal with excellent moisture resistance

· Great for pressure relief

4.Polytetrafluoroethylene (PTFE)

PTFE is a good choice for heat shrink tubing applications that require extreme chemical resistance and a wide temperature range.

· Wide temperature range (-270ºC to 260ºC; -454ºC to 500ºC)

· Unmatched chemical resistance

· Excellent dielectric properties

· Superior lubricity (PTFE tubing creates very little friction in its applications)

· Chemically inert

5.Fluorinated ethylene propylene (FEP)

This material has similar properties to PTFE, but with its own advantages and disadvantages. It offers clarity and the thinnest wall thickness.

· UV and chemical resistant

· Low gas and vapor permeability and solvent absorption

· Chemically inert

· Excellent dielectric properties

· Low coefficient of friction

6.Fluororubber

This rubber material offers great flexibility over a wide temperature range. It is also ideal for heat shrink tubing in aerospace and industrial applications because it is resistant to acids, solvents, and fuels.

· Thermally stable

· Flexible at low and high temperatures

· Abrasion and cut resistant

· Resistant to fuels, acids, solvents, lubricants, and hydraulic fluids

· Weather resistant

7.Polyvinylidene fluoride (PVDF)

This heat shrink tubing material, sometimes listed as Kynar, is a common choice for automotive applications.

· Maintains excellent mechanical properties over a wide temperature range

· Excellent tensile strength and impact resistance

· Radiation resistant

· Resists creep and fatigue

8.Polyvinyl chloride (PVC)

PVC is another popular material choice. Available in both standard and flat heat shrink tubing configurations, it can be used in a wide range of industries and applications.

· Excellent mechanical strength (30% stronger than polyolefins)

· Low shrinkage temperature
