Breyden 75 Series DHS Heat-Shrinkable Polyester Tie Cord
The
Breyden 75 Series DHS Tie Cord is a precision, flat-braided, heat-shrinkable lacing tape engineered specifically for securing the fine end turns of stators in micro-to-midsize electric motor and generator manufacturing. Formulated from premium high-tenacity continuous filament polyester, it features a specialized finish that dramatically reduces fraying and enhances knot-holding capabilities during delicate, high-precision installation.
During the varnish baking cycle, this fine tape shrinks by approximately 10% when exposed to 350°F, creating an incredibly tight, reliable mechanical lock that prevents any shifting, vibration, or loosening of small windings. Rated for Class F applications (up to 155°C), it integrates seamlessly with electrical varnishes and potting resins for a unified, permanent insulation bond.

Applications
Primary Product Applications
The Breyden 75 Series Tie Cord is uniquely engineered to provide high thermal stability and physical restraint for small, high-precision electrical systems. Key applications include:
- Precision Stator Rewinding: Specifically designed for bundling and securing fine end turns of stators in micro-to-midsize motors and generators. The 10% thermal shrinkage tightens during the varnish bake cycle to permanently anchor windings and prevent operation-damaging vibration.
- Class F Electrical Assemblies: Ideal for high-temperature coils, transformers, and electronic components requiring reliable, continuous electrical insulation up to 155°C.
- Delicate Wire Harnessing & Cable Lacing: The narrow profile (.067" - .082" width) allows for precise, tight workspaces in modern control panels and custom wire harnesses without adding excessive bulk or damaging fragile wire jackets.
Key Features & Benefits
- 10% Thermal Shrinkage: Automatically contracts by roughly 10% (±2%) when exposed to 350°F during processing, creating an ultra-tight mechanical lock that traditional tie cords cannot match.
- High Knot Retention: Treated with a specially formulated finish that improves knot-holding security and eliminates frustrating slipping or unraveling during high-tension manual tying.
- Class F Temperature Rating: Built from premium high-tenacity continuous filament polyester, ensuring reliable, continuous performance in demanding thermal environments up to 155°C.
- Excellent Resin Compatibility: Integrates seamlessly with standard electrical varnishes and potting compounds to form a rugged, unified insulation bond around coils.
- Indefinite Shelf Life: Designed for long-term storage stability without material degradation, ensuring the cord retains its full tensile strength and shrinking properties until needed.
