PE heat shrink tubing shares its published range with FEP — 1.00 – 12.70 mm pre-shrink ID, 0.08 – 0.50 mm wall, 2:1 ratio. The choice therefore comes down to material, not size: FEP when chemical resistance and friction matter, PE otherwise.
A 3.00 mm pre-shrink ID finishes near 1.50 mm; 12.70 mm finishes near 6.35 mm.
Used for protective jacketing and bundling where chemical resistance is not critical. Since the range matches FEP, we send both data sheets when you are comparing the two.
Inner diameter, wall thickness, length and operating environment — those four settle the item. We reply with TDS, MSDS and MOQ.
