Frequently Asked Questions
Q1
What temperature range can this fluorine rubber heat shrink tubing withstand?
This tubing operates reliably from -55°C to 200°C, with short-term exposure tolerance up to 220°C. Shrinkage begins at 150°C and is complete at 175°C, making it suitable for high-heat environments such as engine compartments and industrial equipment.
Q2
What chemicals and fluids is the tubing resistant to?
The tubing is highly resistant to fuel, lubricating oil, hydraulic fluid, and a wide range of organic solvents. This makes it an excellent choice for applications in engine compartments, fuel tanks, and hydraulic systems where chemical exposure is frequent.
Q3
What is the shrink ratio and how does it work?
The tubing features a 2:1 shrink ratio, meaning it shrinks radially by 50% when heat is applied. Axial (lengthwise) shrinkage is kept below 20%. Simply slide the tubing over the target component and apply heat at 175°C using a heat gun or oven until fully conformed.
Q4
Does this product meet international environmental and safety standards?
Yes. The tubing is fully compliant with ROHS, REACH, and Sony SS-00259 environmental directives. It is free from halogens and PBDEs. It also carries a UL94 V-0 flame retardancy rating, self-extinguishing within 15 seconds, and is certified to UL, IS9001, and IATF16949 standards.
Q5
What sizes are available and how should I choose the right one?
Sizes range from Ф1.6mm to Ф50.8mm in expanded inner diameter. To select the correct size, measure the outer diameter of the component to be covered. Choose a tubing size whose recovered (after-shrink) inner diameter is slightly smaller than the component diameter to ensure a secure, snug fit.
Q6
How should this heat shrink tubing be stored and packaged?
The tubing is packaged coiled or straight-cut in 50-meter rolls, sealed in moisture-proof bags. Recommended storage conditions are -20°C to 30°C with relative humidity below 70%. Avoid prolonged UV exposure and store in a cool, dry environment to maintain performance.
