Overview
CHR SGK5-05 is a high-performance para-aramid wiring harness tape designed for demanding aerospace and industrial cable protection applications.
The tape combines:
- A para-aramid woven fabric backing
- Anti-static PTFE coating
- High-temperature silicone pressure-sensitive adhesive
The result is a wiring harness wrap with:
- Very high tensile strength
- Excellent abrasion resistance
- Chemical resistance
- Anti-static performance
- High-temperature capability
- Low-friction surface properties
SGK5-05 is engineered for environments where standard fibreglass harness tapes may fail due to:
- Chemical exposure
- Mechanical abrasion
- UV exposure
- Thermal cycling
- Electrostatic discharge requirements
The black pigmentation is not purely cosmetic.
It provides:
- Anti-static electrical properties
- UV stabilisation for the para-aramid substrate
SGK5-05 has a backing thickness of 0.127mm and a total construction thickness of 0.178mm including adhesive.
A linered version — SGK5-05R — is also available for die-cutting and automated application environments.
Aerospace and Industrial Applications
SGK5-05 is specifically designed for aerospace wiring harness and high-temperature cable protection applications.
Aerospace Wire Harness Wrapping
Aircraft wiring harnesses are exposed to:
- Vibration
- Abrasion
- Hydraulic fluids
- Fuel exposure
- Thermal cycling
- Tight routing environments
The para-aramid construction provides significantly higher tensile strength than standard fibreglass harness tapes.
The PTFE surface also reduces friction and wear where harnesses contact adjacent structure or other cable bundles.
Avionics and Anti-Static Environments
SGK5-05 provides anti-static performance with surface resistivity below:
- 10⁶ ohms/in²
This helps reduce electrostatic charge accumulation around sensitive avionics and electronic systems.
The anti-static property is integrated into the material itself rather than added as a surface treatment.
Engine Bay and High-Temperature Cable Protection
The operating range of:
- −73°C to +260°C
makes SGK5-05 suitable for elevated-temperature harness routing environments including:
- Engine bays
- Nacelles
- Thermal processing equipment
- Harsh industrial cable protection
Chemical Exposure Areas
PTFE and para-aramid provide strong resistance to:
- Hydraulic fluids
- Fuels
- Lubricants
- Cleaning chemicals
- Aerospace process fluids
This helps maintain long-term harness protection in wet or chemically aggressive environments.
UV-Exposed Applications
Para-aramid fibres can degrade under prolonged UV exposure.
The black PTFE pigmentation used in SGK5-05 provides UV stabilisation to protect the material during long-term service exposure.
Performance Characteristics
High Tensile Strength
SGK5-05 provides tensile strength of:
- 350 N/cm in warp direction
- 350 N/cm in weft direction
This balanced strength improves durability in demanding harness routing applications.
Low Elongation
Elongation at break is only:
- 3%
This means the tape resists stretching and maintains bundle compression over long service periods.
Anti-Static Performance
The tape provides surface resistivity below:
- 10⁶ ohms/in²
This places SGK5-05 within the anti-static classification range suitable for ESD-sensitive environments.
High Temperature Resistance
SGK5-05 operates continuously between:
- −73°C to +260°C
- (−100°F to +500°F)
The para-aramid backing, PTFE coating, and silicone adhesive all maintain performance across this range.
Chemical Resistance
The PTFE coating helps protect against:
- Aerospace fluids
- Hydraulic oils
- Solvents
- Fuels
- Industrial chemicals
This improves long-term durability in harsh operating environments.
UV Stabilisation
The black pigmentation protects the para-aramid substrate against UV degradation and loss of tensile strength.
Low-Friction Surface
The PTFE surface reduces friction between:
- Harness bundles
- Cable runs
- Adjacent structure
- Routing hardware
This helps reduce wear over extended service intervals.
