Silicone Self-Fusing Tape Cross Section

- Has uniform thicknesses across the cross-section
- Perfect for applications that do not require an even, smooth outer layer of tape
- Most resemble standard electrical tape

- Has a thicker tapered triangular cross-section in the middle
- Great for applications where the coating thickness must not have visible overlap

- Has uniform cross sections with consistent yarn encapsulated sinusoidal glass inside
- Increased controlled elongation and tear resistance between 15 and 25 percent
- Great for applications that require excellent mechanical properties and the ability to conform to complicated shapes.
