Kevlar / Aramid Yarn Braided Sleeves

Kevlar / Aramid Sleeves – High-Strength, High-Temperature Protective Sleeving

Kevlar / Aramid Sleeves are high-performance protective sleeves manufactured from DuPont™ Kevlar® aramid yarn, designed for applications requiring exceptional strength, heat resistance, abrasion protection, and dimensional stability. These sleeves are available in braided or twisted constructions, offering excellent flexibility and adaptability to straight or curved components.

Kevlar / Aramid Sleeves – High-Strength, High-Temperature Protective Sleeving

Kevlar Sleeve | Aramid Fiber Braided Sleeving – Manufacturer in India

Harnawa Insulations is one of the best Kevlar Sleeve manufacturers in India, providing high-performance aramid fiber braided sleeving that has been specifically developed for the applications where cut resistance, impact resistance, and high temperature resistance are as important as insulation properties. Made from aramid fiber, which is renowned for its extraordinary strength-to-weight ratio, our Kevlar Sleeve is the most durable sleeving product among the Harnawa Sleeving Products, which is designed for protecting cables from physical threats. If you want a sleeving material that can protect your cables from abrasion and impacts rather than high temperatures and chemicals, you should consider Harnawa Kevlar Sleeve, which provides unmatched mechanical protection compared to fiberglass or PET sleeving.

What Makes Kevlar Sleeve Different?

In contrast with Harnawa’s other sleeves, which are made of fiberglass, PVC, PU, or coated in silicone, Kevlar Sleeve uses aramid fibers, an artificial fiber type characterized by extreme tensile strength, lightweight construction, and excellent resistance to cuts and abrasions. Unlike conventional materials, aramid fibers will neither melt, nor ignite, or catch fire, thus the protective properties of this sleeve will be entirely different. First of all, it provides protection against physical damage like cuts, impacts, sparks, and splashing hot metals, and then comes the protection against heat and electricity. Therefore, Kevlar Sleeve should be considered when there is a danger of mechanical harm to the cable or hose, for example, cuts, scratches, impacts, etc.

Key Features & Advantages

  • Superior Cut and Abrasion Resistance – Aramid fiber technology provides superior cut, tear, and abrasion resistance compared to fiberglass and PET sleeve materials
  • Superior Strength-to-Weight Ratio – Provides superb mechanical strength without increasing the weight of the cable assembly
  • Wide Temperature Range Performance – Maintains excellent performance characteristics over a very wide temperature range, functioning effectively at both high and low temperatures
  • Will Neither Melt nor Burn – The aramid fibers will neither melt nor catch fire, thus providing good protection against sparks, molten splashes, and open flames
  • High Flexibility – The braided construction allows easy adaptation to cables, hoses, and other parts
  • Chemical Stability – Maintains its structure when subjected to various oils and chemicals
  • Long Service Life – Increased durability decreases the necessity for replacement of the sleeving

Applications of Kevlar Sleeve

Kevlar Sleeve is used wherever cables or hoses need protection from mechanical hazards in addition to heat, including:

Aerospace industry – wiring protection in situations where lightweight and high-mechanical-reliability are required

Marine Applications – protection of cables from wear caused by abrasion, impacts, and other conditions on board

Automobile industry – protection of wiring harnesses in engine bays with high wear and heat conditions

Machinery industry – protection of cables and hoses from sharp edges, sparks, and abrasions

Welding and metalwork sites – protection of cables from sparks, cutting, and molten splash

Heavy industry and foundry industry – protection of cabling from heat and mechanical risks

Kevlar Sleeve vs. Harnawa’s Other Sleeving Options

Sleeve Type Best For
Kevlar Sleeve Cut, impact, and abrasion protection in physically hazardous environments

Frequently Asked Questions

Q1: What is the composition of Kevlar Sleeve?

The composition of Kevlar Sleeve is aramid fibers, a synthetic fiber noted for its high strength-to-weight ratio, anti-cut properties, and temperature resistance.

Q2: What is the difference between Kevlar Sleeve and fiberglass sleeving?

While Kevlar Sleeve is designed mainly for cut, impact, and abrasion resistance, the fiberglass-based sleeves are designed mainly for insulation from thermal and electrical properties. Many applications have Kevlar Sleeve for protection against mechanical hazards alone and not heat.

Q3: Is Kevlar Sleeve safe around sparks and molten splash?

Yes, the aramid fibers neither melt nor catch fire, and therefore the sleeve can be safely used in applications involving sparks, molten splash, and flames.

Q4: Is Kevlar Sleeve chemically resistant?

Yes, the sleeve retains its integrity even when exposed to industrial oils and chemicals.

Q5: Does Harnawa supply Kevlar Sleeve all over India?

Yes. As one of the major manufacturers and suppliers of Kevlar Sleeve in India, Harnawa Insulations provides aerospace, marine, automotive, and industrial OEMs nationwide from our Mumbai and Bhiwandi plants.
