Heat shrink tubing

Heat shrink tubing is used as a protective sheath in applications that are exposed to, among other things, aggressive chemicals, moisture or high temperatures. Because the heat shrink tubing provides a hermetic seal, the service life of products is extended by many years. Polyfluor has 40 years of experience in supplying shrink hoses. In addition to shrink hoses in standard sizes, Polyfluor also supplies industry-specific applications and solutions that are fully tailored to your specific requirements. The specialists at Polyfluor are happy to think along with you to provide you with the best possible support. Below you will find the selection of high-quality shrink hoses from Polyfluor:

Heat shrink tubing, general

Shrink tubes are used as protection cover in applications which are exposed to aggressive chemicals, moisture, high temperatures or other critical environmental factors.


PTFE, FEP and PTFE/FEP heat shrink tubing. For PTFE heat shrink tubing we provide standard shrink ratios of 2:1 and 4:1. Larger ratios are technically possible. The shrink ratio for FEP heat shrink tubing is lower, on average 1.3:1.

PTFE heat shrink tubing

PTFE heat shrink tubing is available in lengths of 1,22 mtr or on spools with production lengths. Standard shrink ratios are 4:1 and 2:1. Larger ratios are technically possible but are not standard and custom made. 

FEP heat shrink tubing

Our FEP heat shrink tubing is available in the following shrink ratios 1.3:1/1.6:1 and 1.25:1 (mainly used for roller covering). The standard colour of FEP heat shrink tubing is transparent/white, other colours available on request.

PTFE/FEP heat shrink tubing

The PTFE/FEP heat shrink tubing consists of a PTFE heat shrink tubing with a meltable FEP heat heat shrink tubing on the inside. During the application, the FEP heat shrink tubing liquefies, while the outer PTFE heat shrink tubing presses the liquid FEP heat shrink tubing on the object.

PVDF (Kynar) heat shrink tubing

Kynar is a material which provides an excellent grinder reliability and durability. Kynar heat shrink tubing has a continuous working temperature of 175°C and can easily withstand a temperature of 350°C for shorter periods.

Viton heat shrink tubing

Viton heat shrink tubing is very suitable for applications requiring high temperature and fluid resistance. Viton heat shrink tubing can withstand fuels, most hydraulic fluids and other chemicals at a continuous working temperature of 200°C.

Polyolefin heat shrink tubing

Polyolefin heat shrink tubing is a general, flexible heat shrink tubing which can be used for a wide range of applications, including military and professional electronics.

PTFE micro heat shrink tubing

Recently we deliver PTFE micro heat shrink tubing with wall thicknesses down to 0,05 mm and tolerances of +/- 0,013 mm. Available in almost every size.

PEEK heat shrink tubing

PEEK heat shrink tubing is available in lengths of 1,22 mtr or production lengths on spools, other lengths on request possible. Recovered wall thickness from 0,10 to 0,25 mm.

TL- and UV lamp protection

Lamps covered with heat shrink tubing for insect control, food and/or food industry or with UV-Stop. Available in divers dimensions on lengths up to 2500mm. Other lengths on request possible.

Applicable in various industries

Polyfluor shrink tubing are used in various industries. Just think of the electronics industry, aviation and aerospace, the automotive industry and the pharmaceutical and medical industry.
