Simili Wrapping Tape – 8 Colors

What is Simili Wrapping Tape?

Simili wrapping tape is a flexible synthetic PVC tape supplied in rolls, known for its high elasticity, durability, and flame resistance. It is commonly wrapped around insulation foam on air-conditioning pipes to protect the insulation layer from mechanical impacts (scratches, dents) and environmental effects such as moisture, mold, and heat.

One of its key benefits is preventing pipe condensation (“sweating”)—when cold copper or water pipes form moisture, causing water stains, reduced aesthetics, and lower system efficiency. Simili acts as a moisture barrier, extending the lifespan of both the insulation and the internal piping.

Composition of Simili Wrapping Tape

Simili tape is typically made from synthetic PVC combined with plasticizers and strengthening additives, giving it:

• High tensile strength

• Tear resistance during wrapping around bends and corners

• Smooth, semi-gloss surface that resists peeling in humid environments

• Heat resistance up to 240°C, suitable for harsh industrial conditions (HVAC plants, cold storage, data centers)

• Dust-resistant and easy-to-clean surface, maintaining neat system appearance

Because of these properties, simili is widely used in commercial buildings such as malls, hospitals, hotels, and airports.

Practical Functions in Insulated Piping Systems

1. Improves Thermal Insulation Efficiency

Wrapping simili over insulation foam seals the surface, preventing external air from entering gaps and reducing heat loss. This improves HVAC efficiency and energy savings.
In exposed piping systems, combining PE foam + simili can improve insulation performance by 10–15% compared to foam alone.

2. Protects Insulation from Mechanical Damage

Insulation foam is soft and easily damaged during installation or maintenance. A simili outer layer:

• Protects against scratches, dents, and impacts

• Prevents insect damage

• Extends insulation service life

This is especially important in factories, warehouses, and high-traffic technical areas.

3. Prevents Moisture, Condensation, and Mold

Simili wrapping helps:

• Block moisture penetration

• Prevent condensation on cold pipes

• Keep insulation dry and mold-free

Applications in HVAC, Industry, and Buildings

Air-Conditioning Gas and Chilled Water Pipes

Most common use: wrapping over insulated copper pipes to:

• Extend pipe lifespan

• Prevent wall/ceiling moisture damage

• Improve aesthetics in apartments, hotels, and offices

Simili is available in multiple colors (white, gray, black) to match interior design.

Steam and Technical Pipelines

In industrial plants, simili protects insulated pipes from dust, oil, and harsh environments. It is heat-resistant and non-flammable, making it safe for high-temperature and potentially flammable conditions.

Color coding is also used for pipeline identification:

• Red: hot/steam/air

• Green: clean water

• Yellow: gas/technical steam

• Black/Gray: refrigerant lines

Typical Projects Using Simili Tape

• Data centers: color-coded insulation systems

• Hospitals & hotels: high aesthetic requirements

• Food factories: hygienic, mold-resistant insulation

• Schools & offices: exposed HVAC piping

Why Choose Simili Wrapping Tape?

Aesthetic and Identification Benefits

Color options help:

• Keep piping neat and professional

• Match building interior design

• Quickly identify pipeline function

Standard Color Coding for Technical Systems

Used to classify:

• Medium type (gas, cold water, hot water)

• Pressure or temperature level

• Technical pipeline routes

This greatly improves maintenance efficiency and safety.

Easier Inspection and Maintenance

• Bright colors reveal cracks or damage easily

• Replacement is simple without affecting insulation

• Reduces maintenance time and labor cost

Proper Installation Guide

Key rule: wrap firmly, not too tight and not too loose.

• Too tight → compresses insulation, reduces thermal performance

• Too loose → gaps allow moisture penetration

Steps:

1. Clean insulation surface

2. Cut tape to required length

3. Wrap in spiral, overlapping 1–2 cm

4. Fix ends with heat-resistant adhesive

5. Inspect entire pipe for gaps

For outdoor or humid areas, double wrapping is recommended for better durability and waterproofing.

Simili wrapping tape enhances insulation lifespan, improves system durability, prevents moisture, and provides a clean, professional appearance. With heat resistance, waterproof performance, and multi-color options, it is an essential material in modern HVAC and mechanical systems.
