Heat shrink tubing is used as a protective sheath in applications where materials are exposed to a wide range of aggressive chemicals, moisture, high temperatures, among other things. Because the heat shrink tubing provides a hermetic seal, the life of the products it protects is extended by many years. Polyfluor has more than 40 years of experience providing shrink tubing. In addition to standard-size hoses, we also provide industry-specific applications and solutions that are fully tailored to your specific requirements. The specialists at Polyfluor are happy to collaborate with you to provide you with the best possible support.
Standard heat shrink tubing is used as a protective sheath in applications exposed to harsh chemicals, moisture, high temperatures, and other critical environmental factors. Because the shrink tube generates a better seal, this ensures a longer life of the product.
Standard shrinkage ratios of 2:1 and 4:1 apply to PTFE materials. Larger ratios are technically possible on request. With FEP, these ratios are significantly lower, with an average of 1.3:1 to 1.6:1.
PTFE heat shrink tubing is available in lengths of 1.22 meters or on reels with production lengths. The standard shrink ratios are 4:1 and 2:1, with larger ratios available on request.
Polyfluor's FEP heat shrink tubing is available in the following shrink ratios: 1.3:1, 1.6:1, and 1.25:1. The standard colour of this hose is transparent/natural, though other colours are possible on request.
The PTFE/FEP heat shrink tubing consists of a PTFE tubing with a fusible FEP tubing on the inside. During application, the FEP hose is liquefied while the outer PTFE hose presses the liquid FEP onto the object, essentially coating it.
Kynar is a material that offers excellent cuttability and wear resistance. Kynar has a continuous working temperature of 175°C and can briefly withstand a temperature of 350°C.
Viton is highly suitable for applications in which temperature and fluid resistance play an important role. Viton can withstand fuels, most hydraulic fluids, and other chemicals at a continuous, operating temperature of 200°C.
Polyolefin heat shrink tubing is a flexible tubing that can be used for a wide variety of applications, including military and professional electronics.
Polyfluor recently supplied micro-thin PTFE heat shrink tubing with a wall thickness up to 0.05 mm and tolerances of +/- 0.13 mm. These hoses are available in almost any size.
PEEK heat shrink tubing is available in lengths of 1.22 meters. Standard shrink ratios are 1.4:1 and 1.3:1. The standard color of this hose is a brown, transparent/beige while other colours are possible on request.
Shrink tubes are widely used in insect control equipment lamps, food industry lamps, and lamps with UV stop.
