PVC Coated Braid Yarn
PVC as the standard for electrical wire harness protection — with PVDF and TPE coated braid yarns available for the most demanding chemical and thermal applications.
Extrusion coated yarn for harness braiding
Braid yarn is a high-tenacity synthetic multifilament core fully encapsulated in an extruded polymer jacket. Braided around an electrical wire bundle, it forms a protective sleeve that shields the harness against abrasion, weathering, temperature swings and aggressive fluids.
Polyvinyl Chloride (PVC) is the proven standard. For the most demanding chemical and thermal environments we also supply PVDF and TPE coated braid yarns.
The proven base for harness protection
Our PVC compound is engineered with proprietary additives for exceptional weathering, moisture and abrasion resistance, cold flexibility, fire resistance with retardance, and resistance to oil, grease and engine fluids. PVC also delivers a uniform surface that braids cleanly at high production speeds.
PVDF and TPE for the toughest jobs
Where PVC reaches its limits, our PVDF and TPE coated braid yarns take over — engineered for extreme temperatures, aggressive chemicals and demanding mechanical loads.
PVDF — Polyvinylidene Fluoride
A fluoropolymer coating with outstanding chemical and thermal stability. Specified where harnesses face aggressive solvents, fuels or sustained high temperatures.
- Temperature: continuous service - 54°C / +150 °C
- Chemicals: excellent against acids, hydrocarbons and fuels
- Applications: automotive, aerospace, chemical processing
TPE — Thermoplastic Elastomer
A flexible elastomeric coating delivering superior abrasion resistance and cold-flex performance. Ideal for harnesses that move, vibrate or operate at low temperatures.
- Temperature: flexible down to -54 °C / 138 °C
- Mechanical: superior abrasion and flex-fatigue resistance
- Applications: construction, agriculture, off-highway equipment
LSZH-ready without a separate variant
If your spec calls for LSZH materials, the TPE-coated yarn qualifies. The coating contains no chlorine or fluorine, meeting halogen-free requirements without a separate product variant.
Rail interiors under EN 45545 are a typical application. So are automotive and industrial harnesses where fire-safety or low-emission specs rule out PVC.
EY-1877 runs from -54°C to +138°C and holds up well against abrasion, oil, and engine fluids. The halogen-free coating does not come at the cost of mechanical performance.
