As a PTFE Guide Tape manufacturer in China, Gansu Juxiang Fluoroplastics Technology Co.,Ltd. supplies sodium-treated, filled PTFE tape for machine tool slideways, guideways and linear motion surfaces. The tape is molded from suspension PTFE resin blended with carbon fiber, copper powder, molybdenum disulfide and other lubricating fillers, then sintered, skived to thickness and etched on one face for adhesive bonding. We produce five JUXIANG grades in thicknesses from 0.3 mm to 4.0 mm and widths from 30 mm to 500 mm, with custom sizes cut to project drawings.
PTFE Guide Tape Range and Machine Tool Fit
Guide tape is the sliding element in a bonded slideway system: a thin, filled PTFE strip is attached to the moving or stationary way and runs against a prepared metal counterface. The filled compound carries load without cold flow, resists abrasion and keeps friction low where hydrodynamic lubrication is intermittent or unwanted. The sodium-treated face provides the bond strength needed for continuous shear loading in machine service.
- CNC machining centres, milling machines and drilling machines
- Surface and profile grinders, planers and heavy machine tools
- Linear guideways, dovetail slides and box ways
- Mechanical transmission systems and wear pads
- Retrofit and repair of worn or scored slideways
The same filled-PTFE platform supports our PTFE Self-Lubricated Tape for dry-running bearings and wear plates, the PTFE Brake Ring for friction and release duties, and Filled PTFE Tube, Rod for machined bushes, seals and piston guides. Guide tape is supplied as skived sheet or roll, not as a finished machined part, so the machine builder controls the final bond, trim and oil-groove geometry.
JUXIANG Grades and Performance Data
Five grades cover the range. They differ in resin and filler formulation and in the balance between tensile strength, elongation, density and friction.
| Grade | Tensile strength, min | Elongation at break, min | Apparent density | Dynamic coefficient of friction |
|---|---|---|---|---|
| JUXIANG-T300 | ≥15 MPa | ≥150% | 2.8–3.0 g/cm³ | 0.25 |
| JUXIANG-T301 | ≥15 MPa | ≥150% | 2.1–2.3 g/cm³ | 0.22 |
| JUXIANG-T3002 | ≥18 MPa | ≥180% | 2.1–2.2 g/cm³ | 0.21 |
| JUXIANG-T303 | ≥15 MPa | ≥150% | 2.5–2.7 g/cm³ | 0.22 |
| JUXIANG-T304 | ≥20 MPa | ≥200% | 2.2–2.3 g/cm³ | 0.20 |
T3002 and T304 carry the highest tensile and elongation values in the range, while T300 has the highest apparent density. Grade selection follows the working point: contact pressure, sliding speed, counterface finish, lubrication state and the stiffness of the bonded assembly. We confirm the grade against those inputs before production.
Thickness, Width and Sodium-Treated Bonding Surface
| Thickness | Thickness tolerance | Width | Width tolerance | Minimum length |
|---|---|---|---|---|
| 0.3 mm | ±0.02 mm | 30–500 mm | ±3 mm | ≥100 mm |
| 0.3–0.5 mm | ±0.03 mm | 30–500 mm | ±3 mm | ≥100 mm |
| 0.5–1.0 mm | ±0.05 mm | 30–500 mm | ±3 mm | ≥50 mm |
| 1.0–1.5 mm | ±0.10 mm | 30–500 mm | ±3 mm | ≥50 mm |
| 1.5–2.0 mm | ±0.15 mm | 30–500 mm | ±3 mm | ≥50 mm |
| 2.0–3.0 mm | ±0.20 mm | 30–500 mm | ±3 mm | ≥40 mm |
| 3.0–4.0 mm | ±0.20 mm | 30–500 mm | ±3 mm | ≥20 mm |
Thickness tolerance tightens at the thin end because bond-line control matters most on precision ways. Widths run from 30 mm to 500 mm with a ±3 mm tolerance, and minimum length depends on thickness. The sodium treatment is applied to one side only; the opposite face remains the untreated sliding surface.
Bonding performance depends as much on preparation as on the tape. The counterface should be clean, dry, flat and free of oil; the etched face should be bonded within the adhesive's open time; and the adhesive should be selected for the service temperature and shear load. After cure, the tape can be trimmed, chamfered and grooved.
Design Data for Load, Speed and Wear
- Wear loss: 0.005 mm/100 km at P = 1.2 MPa, V = 10 m/min
- Friction coefficient: 0.042 at F = 250 N, n = 200 r/min, No. 30 engine oil
- Compression deformation: 0.09% at P = 1.2 MPa, 24 h
- PV limit: 0.05 MPa·m/s at V = 1.0 m/s, dry running
- Adhesive shear strength: 10.4 MPa, R04-858-81
- Specific gravity: 2.3–2.9
These figures are measured under the conditions shown and are used as design inputs, not as universal constants. Dry running, oil lubrication, high ambient temperature and edge loading all shift the allowable PV. For a specific machine, we work from the actual contact area, stroke speed and duty cycle rather than a single catalogue value.
Fitting, Machining and Machine Integration
Guide tape is integrated at the machine build or rebuild stage. The way surface is machined or ground, the tape is cut to width, bonded and clamped or vacuum-bagged through cure, then finished to final thickness where the design requires it. Oil grooves, lubrication holes and wiper clearances are cut after bonding so that the groove depth is referenced to the finished surface.
- Bonding: two-part epoxy or structural adhesive matched to service temperature
- Clamping: uniform pressure through cure to control bond-line thickness
- Machining: sharp tooling, light passes and dust extraction; avoid overheating the etched face
- Grooving: oil pockets and distribution channels cut after cure
- Inspection: flatness, bond coverage and thickness check before assembly
On CNC and machining centre applications, the tape's low friction reduces stick-slip at low feed rates and contributes to smooth axis motion. It is compatible with oil-lubricated and dry-running slideways; the friction coefficient in the table above was measured under oil-lubricated conditions.

Frequently Asked Questions
What is PTFE guide tape used for?
It is a bonded anti-friction liner for machine tool slideways, guideways and linear motion surfaces. The filled PTFE strip runs against a metal counterface to reduce stick-slip, wear and lubrication demand on CNC machining centres, grinders, milling machines, planers and mechanical transmission systems.
Which fillers are used in JUXIANG guide tape?
Our guide tape compounds use carbon fiber, copper powder, molybdenum disulfide and other lubricating fillers in a suspension PTFE resin base. The exact combination varies by grade and is matched to the load, speed and counterface conditions of the application.
What thickness and width can you supply?
Standard thicknesses run from 0.3 mm to 4.0 mm with tolerances from ±0.02 mm to ±0.20 mm, and widths from 30 mm to 500 mm with a ±3 mm tolerance. Minimum length depends on thickness, and custom cut lengths are produced to drawing.
Can the tape be supplied with a sodium-etched bonding surface?
Yes. The standard guide tape is sodium-treated on one side for adhesive bonding, while the sliding face remains untreated PTFE. We confirm the etched face, adhesive compatibility and service temperature with the order so that the bond is matched to the machine duty.
