Textile Covers, Protecting Hoods, Cable Shields and Sleeves

The industrial setting frequently poses risks to actuators, cables, and sensors. Adding a sturdy enclosure can be challenging or unfeasible due to limited space or the presence of moving components.

Levera RoboCover textile cover presents a versatile solution adaptable to various applications. Crafted from aramid (Kevlar) or fiberglass fabrics, these covers are simple to install and adept at shielding equipment from a range of environmental threats, including heat, sparks, impacts, and even fire.

Designed and manufactured entirely in Finland, Levera RoboCover textile covers guarantee a premium product, ensuring proper fitment and longevity.

Aramid (Kevlar) Fabrics

Aramid-based fabric is pleasant to handle and does not cause skin irritation when touching bare skin. Aramid-based sleeves offer good protection against radiant heat up to 350 degrees Celsius.

Chemical hazards for aramid-based fabrics:

• Strong acids: Strong sulfuric acid and nitric acid can weaken aramid fibers over time.

• Strong bases: Strong alkalis such as sodium hydroxide (lye) can affect aramid fibers.

• Organic solvents: Certain organic solvents, such as strong aromatic hydrocarbons and polarizing solvents, can weaken or degrade aramid fibers.

• Oxidizing agents: Strongly oxidizing agents such as hydrogen peroxide and chlorine bleach can have harmful effects on aramid fabrics.

• Ultraviolet radiation (UV light): Long-term exposure to UV radiation can lead to deterioration of aramid fibers.

In current applications, aramid-based fabrics are easy to identify because one side of the fabric has a silver-colored coating and the back side is yellow.

Fiberglass Based Fabrics

Fiberglass-based fabrics are less flexible than aramid-based fabrics. If the operating temperature of the fabric exceeds 300 degrees Celsius, it is recommended to use fiberglass fabric instead of aramid fabrics.

Fiberglass fabrics can withstand heat up to 600 degrees Celsius. Remember that if the temperature of the outer surface of the fabric rises to 500 degrees Celsius, it is likely that the temperature inside the cover can rise very high.

Fiberglass fabrics can cause skin irritation when they come into contact with bare skin. Use protective equipment and eye protection when handling fiberglass fabrics.

Chemical hazards for fiberglass-based fabrics:

• Strong acids: Strong acids, such as hydrochloric acid (HCl) and sulfuric acid (H2SO4), can weaken the fabric fibers.

• Strong bases: Strong alkaline substances such as sodium hydroxide (lye) and potassium hydroxide (lye solution) can affect glass fibers.

• Hydrogen peroxide: Strong oxidizing agents such as hydrogen peroxide can lead to deterioration of glass fibers.

• Hydrofluoric acid: This is a particularly corrosive acid that can dissolve glass fibers and cause serious hazards.

• Organic solvents: Certain strong organic solvents, especially polarizing ones, can affect the resins and coatings used in fiberglass-based fabrics.

• Ultraviolet radiation (UV light): Long-term exposure to very strong UV radiation can weaken the binders of fiberglass fabrics.

• Moisture: Excessive moisture can lead to the growth of micro-organisms and the formation of mold, which can affect the integrity of the fabric.

In current applications, fiberglass-based fabrics are gray in color with a silver coating on the front.

Velcro Strips

Velcro strips, often sold under the brand name Velcro, are a good way to attach the parts of the textile protection to each other when the continuous operating temperature is below 120 degrees.

If necessary, Levera also uses Velcro strips made of metal, which can withstand long-term temperatures of over 400 degrees.

Zippers

Only top-quality zippers are used in Levera's RoboCover protective textiles. If necessary, zippers made of Nomex (Kevlar) fabric are used, with teeth and pullers made of metal.

The maximum operating temperature of high-quality zippers can be over 300 degrees.

Threads, buttons and hooks

Even the best fabric material does not help if the pieces are sewn together with a thread that cannot withstand the same conditions as the fabric.

Leveran's RoboCover textile covers are always sewn with special fire-resistant, reinforced threads. The use of such threads requires special skills and equipment. That's why many competitors use lower quality threads.
