PTFE Coated Glass Sewing Thread
Our glass threads are manufactured from 'E' continuous filament yarns and are totally encapsulated in PTFE. This enhances the resistance to contaminate build up and also helps to repel attacks from most acids and alkalis.
Our PTFE coating is smooth and consistent which allows for maximum performance of the thread and minimises the possibility of kink, strip back and breakage that can be experienced using very high temperature yarns.
We offer 4 grades of glass sewing thread details as follows:

| USA Count | 450 X 12 | 450 X 18 | 450 X 24 | 75 X 12 |
| Diameter (mm) | 0.28 | 0.33 | 0.45 | 0.87 |
| Minimum PTFE Content % | 16 | 16 | 16 | 16 |
| Nominal Yield M/Kg | 6000 | 4000 | 3000 | 1000 |

PTFE COATED STAINLESS STEEL SEWING THREAD
In addition to our glass sewing thread we offer a stainless steel sewing thread manufactured from 316L grade stainless steel that has 275 filaments and 175 torsions per metre.
The nominal PTFE content is 10%; the diameter is 12 microns and the yield 1150 metres nominal after PTFE coating.
The weight is 750 grammes / 1000 metres nominal; breaking load 80 Newton; elongation 1%; and the W/M Linear Resistivity is 9.
The temperature performance where there are no hazardous / corrosive elements present is up to 800°C however in the worst possible environment 350°C. More precise knowledge would be required to give a more accurate temperature rating.
The stainless steel sewing thread is only used where the higher performance characteristics are a necessity due to the high comparative cost. Some of the applications for this product are for high performance thermal engineering; sports surface and filtration.
More details are available on request.
