Strand 01
Multiple PTFE Filament
Multi-strand yarn made from 100 % virgin PTFE filament. Multiple strands are plied together to give the yarn a strong, uniform body that braids cleanly on standard machines.
Strand 02
PTFE Dispersion Impregnation
Each strand is impregnated with PTFE dispersion. The impregnation fills the interstices of the yarn, giving a smooth surface, lower friction and consistent braiding behaviour.
Strand 03
Braiding Input
Designed specifically as the braiding input for PTFE filament gland packing. Compatible with square braid and round braid packing production on standard braiding machines.

How PR103 Fits the PTFE Packing Production Line
Production FlowYarn Loading
PR103 multiple PTFE filament yarn is loaded onto the braiding machine — bobbins, cones or spools per your line configuration.
Braid Formation
The multi-strand yarn is braided into square or round cross-section. PTFE dispersion impregnation keeps the braid smooth and consistent.
Shaping
Shaped braid is calendered to the target cross-section. The low-friction PTFE surface protects the shaft in the finished packing.
Finished Packing
The PTFE filament packing is cut to length, coiled or die-formed into rings, ready for pump and valve gland service.
Applications & Advantages
Yarn PerformanceWhere PR103 Is Used
- Braiding input for PTFE filament gland packing
- Square braid and round braid packing production

Frequently Asked Questions
Buyer Q&AWhat is Multiple PTFE Filament Yarn used for?
PR103 multiple PTFE filament yarn is used as the braiding input for PTFE filament gland packing. It is not itself a finished packing — it is the raw yarn that packing manufacturers feed into a braiding machine. The finished PTFE filament packing is then used for pump glands, valve stems and reciprocating shafts in chemical, petrochemical and high-purity service.
What is the difference between "multiple" PTFE filament yarn and "pure" PTFE yarn?
Both are made from virgin PTFE filament. The "multiple" designation refers to the multi-strand plied construction — several PTFE filament strands are twisted or plied together into a single heavier yarn, then impregnated with PTFE dispersion. This gives a stronger, more uniform braiding input than a single-strand yarn. "Pure" PTFE yarn is a general term that can cover both single-strand and multi-strand forms.
What is the PTFE dispersion impregnation for?
The PTFE dispersion impregnation fills the interstices of the yarn, giving a smoother surface, lower friction and more consistent braiding behaviour. It also improves the chemical resistance of the finished packing and reduces shaft wear in service.
What temperature and pH can the yarn handle?
Service temperature range is −100 °C to +260 °C continuous. pH range is 0–14, suitable for acids, alkalis, solvents and oxidizers. Send your operating conditions and Kaxite will confirm the suitable yarn construction.
Can you supply to third-party packing manufacturers?
Yes. A significant part of our yarn volume goes to other sealing manufacturers who braid their own PTFE packing. We supply in bulk, with OEM labelling and private brand packaging available on qualified volume orders. Material data sheets and batch traceability documentation accompany every shipment.
What yarn count and bobbin format are available?
Standard counts are stocked and custom counts can be produced to match your braiding machine and cross-section size. Bobbins, cones and spools are all available with custom weights and lengths. Send your braiding machine specification and target packing cross-section and we will match the yarn count.
Can I get a free sample before ordering?
Yes. A free sample of the exact count and construction is available for qualified buyers so you can run it through your own braiding machine and check cross-section, twist behaviour and surface finish before placing a production order.
How do I request a quotation?
Send your yarn count or braiding cross-section, quantity, bobbin format and destination port. Kaxite replies within 24 hours with a factory-direct quotation, lead time and packing details.
