TPU Protective Film Compounds | High Transparency, Anti-Yellowing, Scratch-Resistant
TPU Protective Film Compounds
For protective film projects where optical stability and process stability must hold at scale:
low haze, anti-yellowing, controlled blocking/unwind, and reliable surface handling performance.
Supply forms:
TPU film compounds (pellets) for in-house film extrusion
Finished TPU films & sheets (project-based, on request).
Most projects succeed by controlling both formulation and the unwind/handling window.

When to Choose Protective Film TPU (Fast Check)
Choose this route when
- Your project needs high clarity and low haze on real substrates.
- Yellowing or haze increases after heat/UV/aging.
- Roll handling shows blocking, poor unwind, or surface transfer marks.
- Scratches are not “deep”, but become highly visible due to surface/gloss mismatch.
Common target surfaces
- Electronics, appliances, and glossy panels (scratch visibility sensitive)
- Automotive interior/exterior trims (appearance + durability balance)
- Industrial surface protection (unwind stability + value focus)
- General protection with print/lamination steps (process window matters)
Common Failure Modes (Cause → Fix)
Most protective film issues are not “one property missing”, but a trade-off between optics, surface, and roll handling.
| Symptom | Most Common Cause | Fix Direction |
|---|---|---|
| Yellowing after aging / heat / UV | Stabilizer route not matched to exposure; base selection not optimized | Anti-yellowing route selection; align aging condition; verify on real thickness |
| Haze increases after handling / lamination | Surface micro-scuff; gloss mismatch; insufficient surface robustness | Surface robustness tuning; control gloss; reduce scuff visibility |
| Blocking / difficult unwind | Surface tack + pressure/temperature history; anti-block strategy insufficient | Anti-block and unwind tuning; manage slip/anti-block balance; confirm winding conditions |
| Surface transfer marks / “ghosting” | Roll-to-roll contact imprint; cooling/winding pressure sensitivity | Process window tuning; surface engineering; unwind-condition alignment |
| Scale-up defects (gels, lines, instability) | Drying discipline, melt history, filtration mismatch, narrow line window | Drying + filtration strategy; stabilize extrusion window; verify long-run robustness |
Key principle: Protective film must stay “clean” not only in lab optics, but also after
real roll handling, lamination, and aging exposure.

Selection Logic (Shortlist)
We usually shortlist by the dominant risk: yellowing, blocking/unwind, or scratch visibility.
Multi-constraint projects should start from Advanced Functional.
Optical Stability
For projects where clarity and aging stability dominate.
- Anti-yellowing route selection
- Low haze stability after aging
- Appearance consistency at scale
Anti-Block & Unwind
For roll handling and converting stability.
- Blocking control without haze penalty
- Unwind stability and surface transfer control
- Process window robustness
Surface Handling Wear
For scratch visibility, scuff, and touch.
- Scuff visibility reduction
- Gloss / feel tuning
- Handling durability balance
How We Support Trials (Shortlist → Stabilize → Verify)
1) Shortlist
- Film structure & thickness
- Exposure scenario (heat/UV/time)
- Top failure risk(s)
2) Stabilize Line
- Drying discipline and handling
- Haze/gel control strategy
- Unwind stability (winding pressure, cooling)
3) Verify
- Aging (heat/UV) on real thickness
- Unwind + handling simulation
- Appearance acceptance criteria
Request Samples / TDS
To recommend a shortlist quickly, please share the project basics below.
Two quick routes:
- If you extrude films in-house:
share film structure (mono / co-ex / laminate), thickness range, target optics, and line conditions.
We recommend suitable TPU film compounds (pellets) with TDS/SDS. - If you source finished films:
share thickness, width, surface (matte/gloss/printable), roll specs and validation plan.
We quote finished TPU films & sheets accordingly.
- Top risk: yellowing / haze / blocking / scratch visibility / unwind issues
- Exposure: heat/UV duration and acceptance criteria
- Converting: lamination, die-cut, printing steps (if any)
