Hot bending pet protective film < br />
Material: PET, commonly known as polyester resin, is the main variety of thermoplastic polyester < br />.
Usage: 3D glass is made by hot bending. The hot bending film has excellent adaptability to 2.5D/3D screen after hot pressing. Optical grade PET substrates are selected. Flexible hardening layer is coated on the upper surface and silica gel < br/> is coated on the lower surface.
Features: Super high transmittance, no rainbow, anti-fingerprint, multi-layer flexible structure can also provide impact resistance of the screen.
TPU protective film
Material: TPU, thermoplastic polyurethane elastomer, TPU is a macromolecule material synthesized by the reaction of diphenylmethane diisocyanate (MDI), toluene diisocyanate (TDI) and macromolecule polyols, chain extenders.
Usage: Protective film < br /> for various types of protective bags
Characteristics: High permeability
High waterproof (the film with good permeability is usually made of polyether TPU, so its hydrolysis resistance and antimicrobial property are excellent, because of its high strength and excellent water pressure resistance)
Excellent chemical and oil resistance: stronger than general materials < br />.
High strength wear resistance
Excellent transparency: can be adjusted according to the use of transparency and high elasticity: good elasticity, strong resilience, excellent cold resistance
