Every day, electrical engineers and procurement managers across India face the same nagging problems.

Will the insulation hold? and will the sleeving crack under heat?

When you are manufacturing thousands of units, a small failure in a cheap component can snowball into a massive recall. This is why smart manufacturers don't just look for tubing. They look for trust.

At dee5shrink.com, we have spent years building that trust. We are not just a supplier. We are a premier PVC Heat Shrink Tube Manufacturer and Supplier in India, delivering consistent, high-retraction sleeving that meets global standards at domestic prices.

Whether you are insulating EV battery cells, bundling complex wiring harnesses, or colour-coding industrial cables, our tubing is engineered to perform. Every single metre.

What Exactly is a PVC Heat Shrink Tube?

A PVC Heat Shrink Tube is a polymeric sleeve that shrinks tightly around an object when you apply heat.

Made from specially formulated Polyvinyl Chloride, this tubing has a unique "memory" property. It is expanded during manufacturing, and when exposed to temperatures above 100°C, it contracts back to its original diameter.

The result? A snug, seamless layer of protection.

Unlike ordinary electrical tape that unwinds over time, our PVC Heat Shrinkable Sleeves offer permanent insulation. They resist moisture, prevent short circuits, and shield sensitive components from dust and mechanical abrasion.

At Dee5shrink.com, we don't believe in one-size-fits-all. We engineer tubes that fit like a second skin.

Features That Set Our PVC Heat Shrink Tubes Apart

Indian industrial buyers are practical. You don't want flashy marketing. You want data and specifications that matter on the shop floor.

Here is what our Industrial Heat Shrink Tubing delivers:

• Operating Temperature: -20°C to +105°C
• Tensile Strength: Minimum 12 MPa
• Dielectric Strength: >15 kV/mm – reliable insulation even in high-voltage applications
• Flame Retardancy: UL94 VW-1 certified – self-extinguishing

Aesthetic & Usability:

We don't cut corners. Every batch is tested for concentricity and shrink consistency before it leaves our factory.

Industries and Applications We Serve

A PVC Heat Shrink Tube Supplier in India often claims to serve everyone. But at dee5shrink.com, we have deliberately invested in understanding specific industries deeply.

1. Battery and Energy Storage

The electric vehicle revolution is here. From two-wheelers to solar inverters, batteries need reliable insulation.

Our Heat Shrink Tube for Batteries is specifically formulated to wrap cylindrical and prismatic cells. It prevents the positive terminal from touching the metal casing. It resists electrolyte spillage and provides that critical layer of safety every battery manufacturer swears by.

2. Automotive and Transportation

Indian roads are brutal. Vibration, heat, oil, and humidity constantly attack wiring.

Our tubing is used by automotive component manufacturers for wire harnessing, sensor protection, and fuel line identification. Colour-coded sleeves help mechanics identify circuits instantly during maintenance.

3. Electronics and Home Appliances

Inside every AC, refrigerator, and microwave, you will find our sleeving protecting PCB terminals and power cords. It provides strain relief and prevents accidental contact.

4. Renewable Energy

With India rapidly scaling solar capacity, outdoor cabling needs serious protection. Our UV-stabilised PVC tubing withstands prolonged sun exposure without becoming brittle.

5. Furniture and Sports Equipment

Beyond electronics, we supply decorative shrink tubing for gym equipment handles, metal chair legs, and tool grips. Strong. Aesthetic. Affordable.

Why Dee Five Shrink is Recognised as the Best PVC Heat Shrink Tube Company in India

There is no shortage of traders in this market. So why do leading OEMs consistently choose us?

Because we manufacture, not just trade.

Our facility is equipped with in-house extrusion lines and electron beam irradiation units. This means we control every variable—from raw material compounding to final expansion.

Because we understand Indian conditions.

Imported tubes are designed for European climates. Indian summers are different. Indian industrial lubricants are different. We formulate our PVC to perform specifically in our environment.

Because we believe in partnership.

When you call us with a problem—say, a tube that won't slide over an odd-sized terminal—we don't give you a catalogue. We give you a solution. Our engineers work with yours to modify the inner diameter or wall thickness until it fits perfectly.

That is why procurement managers confidently rank us as the Best PVC Heat Shrink Tube Company in India.

Behind the Scenes: How We Manufacture PVC Heat Shrinkable Sleeves

Most buyers never see how their tubing is made. Let us pull back the curtain.

Step 1: Compounding
We start with virgin PVC resin. No recycled content. No cheap fillers. We add precisely measured plasticisers for flexibility and antimony trioxide for flame retardancy.

Step 2: Extrusion
The compound is melted and extruded into a seamless tube. Precision dies ensure consistent wall thickness—no thin spots.

Step 3: Cross-linking
This is the secret sauce. The tube passes through an electron beam. This cross-links the polymer chains, giving the material molecular memory.

Step 4: Expansion
The tube is heated and vacuum-expanded to a larger diameter. Hot air balloons it outward.

Step 5: Quenching
Immediately, it is cooled rapidly. The expanded shape is now locked in, waiting for heat to trigger its return.

The result is a Industrial Heat Shrink Tubing that shrinks on command, evenly and reliably.

Quality Standards We Adhere To

In India, the term "quality" is often thrown around loosely. At dee5shrink.com, we let certifications do the talking.

• RoHS Compliant: Absolutely no lead, cadmium, or hazardous phthalates.
• UL 224: Recognised component for extruded insulating tubing.
• ISO 9001:2015: Quality management systems across production and dispatch.
• IS 1258: Compliance with Indian standards for PVC insulation.

Every shipment carries a batch number. If something goes wrong—and it rarely does—we can trace it back to the exact shift and extruder line.

Frequently Asked Questions (FAQs)

1. Is PVC heat shrink tube better than polyolefin for batteries?

We maintain inventory of flat widths from 1.5mm all the way up to 150mm. The most commonly ordered sizes are 3.2mm, 6.4mm, 12.7mm, and 25.4mm. If you need something in between, we can manufacture tooling specifically for you.

2. I need heat shrink tube for cylindrical battery cells. Will it fit snugly?

Yes, absolutely. Our Heat Shrink Tube for Batteries is engineered specifically for 18650, 21700, and prismatic cells. We recommend a tube with an expanded ID slightly larger than the cell diameter. When heated, it contracts tightly without air pockets.

3. Do you sell in small quantities or only bulk?

We work with everyone. If you are an R&D lab or a small repair workshop needing just 10 metres, we can supply that. Obviously, bulk orders get better pricing, but we never say no to a serious buyer just because their quantity is small.

4. How do I know which wall thickness to choose?

Standard wall thickness before shrink is around 0.15mm to 0.20mm. After shrinking, it doubles. If you need extra mechanical protection—say, for a battery pack that will vibrate constantly—go for medium wall. For simple wire identification, thin wall is perfectly fine. Still confused? Call us. We will walk you through it.

5. How should I store PVC heat shrink tubing?

Keep it away from direct sunlight and heat. PVC contains plasticisers that can migrate if exposed to UV or extreme temperatures for long periods. A cool, dark cupboard is ideal. Stored properly, our tubing lasts over three years.

Final Call to Action

You have read the specifications. You have seen the quality commitment.
