Pure PTFE Yarn – PR101
Kaxite Sealing, a professional China PTFE yarn manufacturer, presents the PR101 Pure PTFE Yarn – a high‑quality, oil‑free multifilament yarn engineered for the production of braided PTFE packing and other sealing applications. Made from 100% virgin PTFE resin, this yarn offers exceptional chemical resistance, low friction, and wide temperature stability, making it an ideal raw material for valve stem packing, pump seals, and static sealing components.
Why PR101? Our pure PTFE yarn is manufactured without any oil or lubricant additives, ensuring clean, contamination‑free braiding for critical fluid handling systems. It is available in three grades – A, B, and C – to suit different performance and cost requirements. Grade A offers the highest tensile strength and uniformity for demanding industrial applications, while Grade C provides a cost‑effective solution for general‑purpose sealing.
As a leading packing material supplier in China, Kaxite supplies the PR101 in various denier and spool sizes, with consistent quality and on‑time delivery. This yarn is the preferred choice for packing manufacturers, maintenance contractors, and OEMs worldwide. Request a free sample or get a wholesale quote today.

Why PR101 Pure PTFE Yarn?
- 100% Virgin PTFE – No regrind or filler, ensuring consistent purity and performance
- Oil‑Free Formulation – No contamination risk for sensitive processes; ideal for food, pharmaceutical, and chemical applications
- Excellent Chemical Resistance – Resists virtually all chemicals except molten alkali metals and elemental fluorine
- Wide Temperature Range – Maintains flexibility from -200°C to +260°C
- Three Grade Options – Grade A (highest strength), Grade B (balanced), Grade C (economical) – choose the right one for your needs
- Consistent Denier & Twist – Uniform yarn quality for stable braiding and packing performance
Grade Selection & Performance Overview
The PR101 series is offered in three grades to accommodate a wide range of braiding and sealing applications. Grade A is produced with tighter process controls and premium PTFE resin, delivering maximum tensile strength and minimal diameter variation – recommended for high‑pressure and high‑speed rotating equipment. Grade B offers a balanced combination of strength and cost, suitable for most industrial packing applications. Grade C is a cost‑effective solution for general‑purpose, non‑critical sealing tasks.
| Property | Grade A | Grade B | Grade C |
|---|---|---|---|
| Tensile Strength (cN/tex) | ≥ 35 | ≥ 30 | ≥ 25 |
| Elongation at Break (%) | 15–25 | 20–30 | 25–35 |
| Denier Range (g/9000m) | 400–1200 | 300–1200 | 200–1200 |
| Diameter Variation | ±3% | ±5% | ±8% |
| Oil Content | 0% (Oil‑Free) | ||
| Recommended For | High‑pressure valves, pumps, critical service | General industrial packing | Non‑critical, low‑cost applications |
* Custom denier, twist levels, and spool sizes (e.g., 1kg, 2kg, or 5kg spools) are available upon request. Contact our technical team for grade selection assistance.
Key Advantages of PR101 Pure PTFE Yarn
Chemically Inert – Resistant to almost all corrosive media including acids, alkalis, solvents, and hydrocarbons.
Low Coefficient of Friction – Reduces wear on pump sleeves and valve stems, extending equipment life.
Excellent Thermal Stability – Performs reliably from -200°C to +260°C, with short‑term peaks up to 300°C.
Oil‑Free Construction – No lubricant migration, making it suitable for oxygen service, food processing, and pharmaceutical environments.
Consistent Braiding Quality – Uniform yarn diameter and twist ensure dense, homogeneous packing with reliable sealing performance.
Grade Versatility – Three grades allow you to balance performance and cost for each specific application.
Typical Applications
Braided PTFE Packing Raw material for valve stem and pump packing in chemical, petrochemical, and general industrial services.
Gasket & Seal Manufacturing Base material for PTFE gaskets, wrapped seals, and custom sealing profiles.
Food & Pharmaceutical Oil‑free yarn suitable for FDA‑compliant packing used in food processing and pharmaceutical equipment.
Oxygen Service Oil‑free grade eliminates combustion risk, making it ideal for oxygen valve and compressor sealing.
Cryogenic Applications Remains flexible and seals effectively at temperatures as low as -200°C for LNG and liquid nitrogen service.
General Maintenance Used by maintenance workshops and packing distributors for in‑house braiding and repair kits.
