Core Technology

Closed-Cell NBR Elastomeric

Nitrile Butadiene Rubber closed-cell foam - our flagship insulation. The closed-cell structure prevents moisture absorption (the number 1 cause of insulation failure in humid climates) while delivering class-leading thermal performance across HVAC and process applications.

Zero water absorption
No surface condensation
Flexible at −40°C
Long-term dimensional stability
Technical Data
Thermal Conductivity≤0.0321 W/(m·K)
Temperature Range−40°C to +105°C
Water Vapour Resist.μ ≥ 7,300
Fire ClassB1 / BS Class O
02 / 06
Ultra Performance

Gulf-O-Flex NBR Ultra

Ultra-density NBR engineered for projects that demand the best - district cooling mains, chiller plants, and critical pharma/data-centre piping. Higher cell density delivers improved thermal lambda and stronger mechanical performance over standard NBR.

Up to 8% thinner wall
Higher compressive resistance
Premium chiller-line spec
Enhanced acoustic damping
Technical Data
Thermal Conductivity≤0.033 W/(m·K)
Temperature Range−50°C to +110°C
Water Vapour Resist.μ ≥ 10,000
Density70–90 kg/m³

Ultra Line · Pre-formed

Gulf-O-Flex NBR Ultra Line

Pre-formed, line-extruded NBR Ultra tubes and sheets cut to project lengths in our factory - eliminating site-seam losses, ensuring uniform thickness, and dramatically reducing installation time on long pipe runs and large-diameter plant.

Factory pre-cut to BOQ
Zero seam-loss energy
−30% installation time
Consistent λ over the run
Technical Data
Tube Lengths2 m / 5 m / Custom
Thicknesses9 → 50 mm
Pipe Sizes6 → 168 mm OD
Factory Tolerance±0.5 mm

Advanced Polymer

Cross-Linked Polyethylene (XLPE)

XLPE foam extends performance into higher-temperature applications while staying flexible and easy to install. The cross-linked molecular network provides superior resistance to compression, UV exposure, and aggressive chemical environments.

Higher heat resistance
UV-resistant formulation
Chemical inertness
Lightweight & easy to cut
Technical Data
Thermal Conductivity≤0.038 W/(m·K)
Temperature Range−50°C to +120°C
Density25–35 kg/m³
Compressive Strength>100 kPa

Sound Control

Acoustic Insulation System

Gulf-O-Flex Sound is engineered for combined thermal and acoustic performance on HVAC ducts, pumps, and mechanical rooms. A multi-layer composite of mass-loaded vinyl, NBR foam and fibre delivers up to 32 dB sound reduction.

Duct-borne noise cut
Impact sound damping
Thermal + acoustic in one
Pre-slit for fast fitting
Technical Data
Sound Reduction IndexUp to 32 dB
Frequency Range100–3150 Hz
