Choosing the right Paint Protection Film (PPF) can be confusing, especially with so many brands claiming to offer the “best protection.” But the real difference often comes down to one thing:
What material is the film made from — PU or PCL?
At Detailing Bros, as the official distributor of KEVLAR FILMS USA in Pakistan, we only use the latest PCL-based TPU technology because it delivers unmatched clarity, durability, and long-term value for car owners.
This blog explains the difference in simple words so every customer can understand why PCL technology is the gold standard in modern PPF.
What is PU (Polyurethane)?
PU (polyurethane) is a common material used in many mid-range PPF films. When the flexible part is made from polyether, it’s known as:
PU-PE
Polyether-based PU
PU films are:
Soft
Flexible
Decent at resisting humidity
But they have limits, especially with yellowing, clarity, and scratch healing.
What is PCL (Polycaprolactone)?
PCL (Polycaprolactone) is a next-generation polymer used in high-performance TPU PPF. It has a semi-crystalline structure that gives:
Superior clarity
High UV stability
Smoother, glossier surface
Better scratch self-healing
This is why top global brands—including KEVLAR FILMS USA—choose PCL for premium paint protection films.
PU vs PCL (Simple Comparison for Customers)
1. Yellowing & UV Resistance
PU: Can turn yellow when exposed to Pakistan’s harsh sunlight.
PCL: High UV stability → stays clear for years.
Winner: PCL
2. Scratch Self-Healing
PU: Heals slowly and depends heavily on top coat.
PCL: Fast self-healing using sunlight or warm water.
Winner: PCL
3. Gloss, Shine & Clarity
PU: Good but may show orange peel.
PCL: Crystal-clear, high gloss, and very smooth finish.
Winner: PCLPerfect for premium cars and dark colors.
4. Chemical & Stain Resistance
PU: More prone to marks from fuel, acid rain, or bird droppings.
PCL: High resistance to stains and chemicals.
Winner: PCL
5. Long-Term Durability
PU: Decent, but may lose clarity or elasticity over time.
PCL: Designed to last longer while keeping its shine and clarity.
Winner: PCL
