Automotive Wire Harness Protection
Expandable PPS Sleeve
Made from 8 mil flame-retardant PPS (polyphenylene sulfide) monofilament, the expandable PPS sleeve is designed for high-temperature, flame-retardant wire harness and cable assemblies. It offers excellent heat resistance, and resists acids, alkalis, solvents and fuels. Ultra-lightweight and highly abrasion-resistant, it delivers reliable protection in high-durability environments.

PPS Expandable Sleeving for Automotive Harnesses
Expandable braided construction
Flexible braided structure: A stretchable braided mesh design used as a cable sheath that does not trap heat or moisture.
Excellent abrasion and cut resistance
Highly abrasion-resistant, cut-resistant and tear-resistant, with a smooth, stain-resistant surface that resists aging and fading.
Broad chemical and solvent resistance
Highly resistant to acids, alkalis, oils, fuels and most organic solvents, stable across pH 1–14, with chemical inertness to steam, strong alkalis, fuels and acids.
High-temperature & flame-retardant performance
Operating temperature from -70°C to +200°C Low flammability, toxicity and smoke generation, and very low outgassing in vacuum.

Expandable PPS Sleeving Applications in Automotive Wiring
APPLICATION 01
Engine Compartment Harnesses
Engine compartments expose wiring to high heat, oils and chemicals. Expandable PPS sleeving resists temperatures up to 200°C and stays stable against acids, alkalis, oils and fuels, protecting engine-bay harnesses and powertrain wiring..
APPLICATION 02
Racing Applications
Racing environments demand both flexibility and strength. Lightweight Expandable PPS sleeving performs reliably in high-durability motorsport wiring.

Frequently Asked Questions
1.Can Expandable PPS sleeving be used in engine compartments and near exhaust systems?
Yes. Expandable PPS sleeving operates from -70°C to +200°C and resists oils, fuels and most chemicals. It suits engine-compartment harnesses, exhaust-area wiring, and exhaust and fuel line protection.
2.How does PPS sleeving compare to PET sleeving?
Both expandable sleeving options protect cables from abrasion, but they are built for different environments. PPS operates at up to 200°C and resists acids, alkalis, fuels and most organic solvents, while PET is rated to 150°C and handles common oils and fuels. For general-purpose wiring without extreme heat or chemical exposure, PET is the economical choice. Where temperatures run high or chemicals get aggressive, PPS is the safer pick.
3. What are the key benefits of using expandable PPS sleeving?
It withstands continuous heat up to 200°C, is inherently flame-retardant (UL94 V-0), resists acids, alkalis, oils, fuels and most organic solvents across pH 1 to 14, absorbs almost no water, and its open-mesh design does not trap heat or moisture.
4.What industries commonly use PPS sleeving for wire protection?
Automotive (engine compartments, exhaust and fuel lines, EV high-voltage wiring), railway electrical systems, industrial robotics, heavy machinery, energy installations, and marine or HVAC systems exposed to chemicals and moisture.
