the Comparison between TPH, TPU, and EPU Hydrogel materials specifically for smartphone screen protectors

1. TPH (Thermoplastic Hybrid) Screen Protector

Characteristics:

• A blend of plastic and rubber-like thermoplastic

• Thin, flexible, and easy to apply

• More scratch-resistant than TPU, but not as tough as tempered glass

Advantages:

• Budget-friendly

• Easy installation with minor self-healing ability

• Flexible enough for curved screens

Disadvantages:

• Less clear than glass protectors

• Limited impact protection

• Not as smooth to the touch as real glass

• 
  

2. TPU (Thermoplastic Polyurethane) Screen Protector

Characteristics:

• Highly elastic and durable material

• Self-healing properties for minor scratches

• Extremely flexible, suitable for edge or curved screens

Advantages:

• Strong flexibility and scratch resistance

• Ideal for curved or wraparound screens

• Shatterproof and resistant to pressure

Disadvantages:

• May appear slightly hazy and prone to yellowing over time

• Less smooth touch surface compared to glass

• Limited drop protection

• 
  

3. EPU Hydrogel (Elastomeric Polyurethane Hydrogel) Screen Protector

Characteristics:

• Advanced combination of soft polyurethane and hydrogel layer

• Ultra-thin and highly responsive to touch

• Preferred for curved and high-end smartphone screens

Advantages:

• Extremely flexible and smooth (soft, cool touch feel)

• Highly responsive to touch and fingerprint sensors

• Perfect edge-to-edge fit on curved displays

• Often features self-healing properties

Disadvantages:

• More expensive than TPH and TPU
