Automotive Insulation

Automotive E-glass insulation (electrical-grade fiberglass) is used primarily as a high-temperature, lightweight, and sound-absorbing material to improve vehicle performance, passenger comfort, and safety.

Key Uses of E-Glass in the Automotive Industry

• Thermal Management & Exhaust Insulation: E-glass needled mats are extensively used in muffler assemblies, catalytic converters, and exhaust silencers to withstand high temperatures (up to 700°C) and reduce noise.
• Engine & Under-Hood Insulation: Due to its resistance to heat and chemicals, it is used to protect sensitive components from engine heat.
• Acoustic & Noise Reduction: Used to improve cabin comfort by absorbing road, engine, and vibration noise.
• EV Battery Fire Containment: Specialized E-glass fiber mats are used as fire-resistant barriers in electric vehicle battery packs, providing essential fire containment and thermal isolation for lithium-ion batteries.
• Structural Reinforcement (Composites): E-glass fibers are used to create lightweight, high-strength composite parts, such as dashboards and door panels, improving fuel efficiency.
• Electrical Insulation: Used for wrapping and insulating cables and wires, owing to its high dielectric properties

Exhaust Silencer Packing

Heat & Noise Shields

Due to the large amounts of heat given off by internal combustion engines, heat shields are used on most engines to protect components and bodywork from heat damage. As well as protection, effective heat shields can give a performance benefit by reducing the under-bonnet temperatures, therefore reducing the intake temperature. Heat shields can be cut and fitted to any specification.

Exhaust Wrap/Tape

Firesleeves

Darco Industries silicone coated fiberglass sleeves have an extra thick, special formulation of silicone rubber on them. They protect industrial hoses and lines from molten metals, slag, welding splatter, electrical or grinding sparks and contamination. They also provide protection from ozone, UV and abrasion. The standard color of coating is red oxide. The “danger red” colour of the silicon rubber is due to heavy loading of iron oxide to improve heat resistance. We also have black sleeves available, and silicone self-fusing tape, to seal the ends of the firesleeve, and Velcro firesleeves (Indent).

Silicone Self-Fusing Tape

Application

• Used to seal the ends of the Firesleeve's
• Used for split hoses
• Seals the end of firesleeves
• Sticks to itself (No adhesive needed)
• Permanent Seal, Waterproof & Airtight
• Rated - 50°c up to 260°c
• Stretches to 250% its original size
• Breakdown Voltage: 12kV
• Available In Red or Black

EV and ICE Car Fire Blanket

The most efficient way to isolate and extinguish car fires, even in electric vehicles.
Any car fire is dangerous and toxic. A car fire in a gas station, road tunnel, car park or passenger ferry can
be a disaster. The Car Fire Blanket enables you to contain the flames, smoke and toxic fumes in a car fire
in seconds and extinguish it in minutes. It's the only solution that can effectively handle fires in electric cars.

Handles normal size vehicles up to SUVs such as Land Rovers, XC90, etc.

Now Available in a new zippered bag with wheels making it easier to move to fire location open and rapidly deploy

Heavy Duty Insertion Rubber

All items with a Darco Stock Code are bulk imported and in stock.

Darco DNR/SBR3 & DNR/SBR6 is a black, superior grade, blended 60 Duro Natural and Synthetic rubber sheets, reinforced with heavy Conveyor Belt Nylon fabric. The strong Nylon fabric reinforcement gives extremely high tear strength and dimensional stability and making it suitable for heavy duty hanging applications.

Application
Darco Heavy Duty Natural Insertion Rubber has been designed primarily for use as a flexible strip, pad, curtain or skirt and is mainly used for Sealing, insulating, isolating and protecting, steel or other surfaces. Its properties make it suitable for use in a wide range of applications including:

• Transport mud guards and flaps
• Machinery and heavy equipment flaps
• Fencing protection
• Cricket net protection
• Equine rail dividers
• Round yard barriers
• Heavy duty skirts and curtains
• Insulating strip
• Isolation barriers
• Heavy duty dust seals and covers
• High strength reinforced strips
• Variety of sealing applications

EPDM Rubber Sheet *INDENT ONLY

Darco DPEPDM3/DPEPDM6 is a black premium grade 70 EPDM rubber sheet, reinforced with a tear resistant Nylon monofilament fabric. It has high temperature resistance and chemical resistance to acids and alkalis. It is completely UV stabilized making it highly resistant to ozone effects and extreme weather conditions and is ideal for long term outdoor applications.

Application
The specially designed Nylon monofilament fabric reinforcement will not allow fluid penetration and gives EPDM Insertion improved tear strength and dimensional stability, making EPDM Insertion suitable for gasket sealing applications.
