Premium PVC Heat Shrink Sleeve for Lithium Battery Pack – Manufacturers & Suppliers in India
Protect, insulate and professionally finish your lithium battery packs with our durable PVC heat shrink tubing battery wrap. Trusted by EV manufacturers, solar installers and DIY battery builders across India.
Introduction
In today's fast-growing electric vehicle, renewable energy and portable power markets, reliable battery insulation is non-negotiable. Our PVC heat shrink sleeve for lithium battery pack is the first choice of battery pack manufacturers and DIY enthusiasts because it delivers superior electrical insulation, mechanical protection, weather resistance and a clean professional look.
Whether you need PVC heat shrink tube for battery wrapping of 18650, 21700, 32650, 32700 cells or complete module sleeving, our PVC heat shrink sleeves are engineered to shrink tightly at 90–100°C and stay flexible for years.
What is PVC Heat Shrink Sleeve / Tube?
PVC Heat Shrink Sleeve (also called PVC heat shrink tubing battery wrap) is a high-quality polyvinyl chloride tube that shrinks radially when heated. Once shrunk, it forms a tight, conformal protective skin around battery cells, busbars, wiring harnesses and entire battery packs.
Key Features
Excellent Dielectric Strength
Rated 300V – prevents short circuits and accidental contact between cells.
Flame-Retardant
Self-extinguishing material adds a critical safety layer for Li-ion and LiFePO₄ packs.
Wide Temperature Range
Operates from -10°C to +105°C, shrinks cleanly at 90–100°C.
40–45% Shrink Ratio
Transversal shrink with 5–10% longitudinal and 0.15 mm wall thickness before shrink.
Multiple Colors
Sky Blue, Parrot Green, Black, Red, Clear, Yellow and custom colors on request.
Seals Against Elements
Moisture, dust, chemicals and abrasion protection for long battery life.

Applications – PVC Heat Shrink Sleeve for Lithium Battery
How to Apply PVC Heat Shrink Tubing Battery Wrap
- Choose correct flat width (93 mm flat ≈ 58 mm round after shrink).
- Cut to required length + 10% extra.
- Slide sleeve over battery pack or cells.
- Apply even heat from one end using heat gun (avoid direct flame on large packs).
- For maximum protection: apply second layer perpendicular to first + thin foam sheet inside.
- Let cool for 30 seconds – sleeve will be tight and wrinkle-free. Total time: under 2 minutes per pack.
