Can you supply different spool types and private labeling?

Yes. Spool or cone packaging is available, and private label packaging can be provided for distributors and OEM customers.

Will the thread smoke or melt when exposed to flame?

Fiberglass does not melt like organic fibers. In flame exposure, the behavior is significantly more stable than polyester or nylon threads. Performance also depends on seam design and the stitched materials.

Product Q&A

Q:What is this thread mainly used for?

It is mainly used for sewing high temperature insulation products such as fire sleeves, exhaust insulation blankets, turbo blankets, heat shields, and protective covers where ordinary polyester or cotton threads fail quickly.

Q:Why choose PTFE coated fiberglass thread instead of uncoated fiberglass thread?

PTFE coating improves sewing smoothness, reduces fraying, and lowers friction heat at the needle. It helps achieve more consistent stitches and fewer thread breaks, especially on abrasive or coated fabrics.

Q:Is it suitable for continuous high temperature service?

Yes. The fiberglass base supports high temperature stability. Typical continuous use is up to 260 degree C, while short-term exposure can be higher depending on the stitched structure and surrounding materials.

Q:Does the thread resist chemicals and oil splash?

PTFE coating improves resistance to moisture, oil splash, and many chemicals. Actual compatibility depends on the specific chemical, concentration, and temperature.

Q:Which thread size should I select?

It depends on the thickness and hardness of the substrate, seam design, and required seam strength. Provide your fabric type and layers, and we can recommend an appropriate Tex size and spool form.
