Which material of mirror protective film is better

Mirror Protective Film Material Guide

PET (Polyethylene Terephthalate)

PET is a popular baseline option: lightweight, flexible, and affordable. Its thin structure allows easy application on flat screens, and it provides basic scratch resistance and a clear mirror effect.

Advantages: Lightweight, flexible, affordable, easy application
Limitations: Lacks durability against heavy impacts, may yellow over time with UV exposure
Protection Level: Basic scratch resistance

Best for: Low-traffic devices or temporary use

TPU (Thermoplastic Polyurethane)

TPU improves on PET with better elasticity and shock absorption. Its ability to self-heal minor scratches extends lifespan, while maintaining flexibility for curved screens.

Advantages: Better elasticity, shock absorption, self-healing, curved screen compatibility
Limitations: Lower rigidity can slightly diminish mirror sharpness
Special Feature: Gentler adhesive layer reduces residue risks during removal

Best for: Users prioritizing durability on curved or frequently handled devices

Tempered Glass

Tempered glass stands out for premium protection. Its hardness (typically 9H on the Mohs scale) resists deep scratches and impacts, significantly lowering screen breakage risks.

Advantages: Premium protection, preserves clarity and smoothness, minimal distortion
Limitations: Heavier, thicker, less flexible, higher cost for curved versions
Special Features: Often includes anti-fingerprint coatings and enhanced reflection

Best for: Users valuing sharp mirror effects and robust defense on flat screens

Hybrid Materials

Hybrid materials combine PET/TPU backings with glass-like top layers to balance flexibility and protection.

Advantages: Better impact resistance than PET, more curve compatibility than glass
Limitations: Mirror clarity may slightly lag behind pure glass
Special Options: Available with UV inhibitors or water resistance for outdoor use

Best for: Environments needing balance between flexibility and protection
