High-Frequency Weldable Airtight PVC

Technical Parameters

Material Selection Guide

Selection should prioritize the required seam strength and the operational environment of the final product.

• Seam Strength Need: For maximum load-bearing seams (e.g., boat hulls), select fabrics with higher tensile strength base cloth (1000D or higher).

• Temperature Tolerance: If used in marine or outdoor applications, verify the film has cold-crack resistance to ensure seam flexibility at low temperatures.

• Aesthetic Preference: Available in high gloss (easier to clean) or matte finish (less reflective) depending on the end-user requirement.

Manufacturing and Tailoring

We strictly control the compound’s dielectric constant to ensure welding consistency.

• Additive Control: Specific stabilizers and flame retardants (if requested) are incorporated without compromising the material's dielectric properties essential for HF welding.

• Width and Gauge Precision: The fabric is coated to an exact thickness with minimal deviation, guaranteeing uniform material overlap and reliable seam thickness.

• Weldability Testing: Samples from every batch are tested on in-house HF welding equipment to confirm fusion quality and seam strength before roll release.

Deployment FAQ

• Q: Can this fabric be used with hot air welding machines as well?

  A: Yes, while optimized for HF welding, the material is fully compatible with professional hot air welding equipment, providing a reliable, if slower, seam solution.

• Q: Does the color affect the HF welding speed?

  A: No, unlike hot air welding where dark colors absorb heat faster, the HF welding process relies on the material's dielectric properties, which are independent of the visible color pigment.
