PVC Heat Shrink Sleeve for Capacitor
Electrolytic Capacitor Insulation Sleeves Manufacturers & Suppliers
Premium PVC Heat Shrink Tubing for Capacitors – perfect insulation, glossy finish & protection for electrolytic, power factor & motor run capacitors.
What is PVC Heat Shrink Sleeve for Capacitor?
PVC Heat Shrink Sleeve for Capacitor is a high-quality, flexible PVC tube that contracts when heated (80–120°C), forming a perfect insulating jacket around cylindrical capacitors. It is widely used by capacitor manufacturers and OEMs to insulate the body of electrolytic capacitors, improve safety, enhance appearance, and extend product life.
Available in translucent and opaque colors, our sleeves are manufactured with 150–250 micron thickness and offer up to 40–50% transversal shrinkage.

Applications of PVC Heat Shrink Sleeve for Capacitor
How to Apply PVC Heat Shrink Sleeve on Capacitor (Step-by-Step)
- Select the correct sleeve size using our compatibility chart.
- Cut the sleeve slightly longer than the capacitor body.
- Slide the sleeve smoothly over the capacitor.
- Apply even heat using a heat gun (90–110°C) or conveyor oven – start from the center and move outwards.
- Allow natural cooling for 2–3 minutes.
- Inspect for wrinkles or air gaps and re-heat if necessary.
