## TPU Development Journey — Continuous Innovation of High‑Performance Paint Protection Film

## Car Film Development Journey

##### Evolution of Our TPU Paint Protection Film Technology

### Phase 1. Automotive Window Tint, Industry Origin | 1970‑1990

Window solar film was the earliest mass‑adopted automotive functional film. Early dyed‑only films delivered basic shading. From the 1980s‑1990s, metal‑sputtered window‑tint technology was commercialized to provide heat‑rejection and UV‑blocking performance. International brands such as 3M and LLumar introduced window tint into China in late 1990s, launching the country’s automotive‑aftermarket film industry. Primary function: Heat insulation & glass protection, no contact with vehicle paintwork.

### Phase 2. Birth of Clear Paint Protection Film (Clear PPF) | Military origin in 1966, Civil launch in 2004

The first paint‑protection film was developed in 1966 by 3M for the US military, known as “Rhinohide”, to shield helicopter rotor blades against sand abrasion. It was later adopted by motor‑racing teams in the 1990s. In 2004, clear protective films were released for civilian passenger cars across North America. Initially, this luxury product was only applied on high‑end vehicles for partial‑paint protection on door sills and bumper edges. Early PU / PVC‑based clear films suffered fast yellowing and short service life. In 2009, the first wide‑width TPU clear paint‑protection film was launched with thermal self‑healing scratch resistance, founding the modern‑day clear‑PPF industry. Primary function: Invisible paint protection, no color modification.

### Phase 3. Rise of PVC Color‑Change Wrap Films | 1995‑2015

PVC (Polyvinyl Chloride) is the first‑generation decorative wrap substrate. As vehicle‑customization culture boomed across Europe & North‑America in the 1990s, low‑cost PVC wraps made full‑vehicle recoloring accessible. After 2010, PVC wraps flooded the Chinese market, once holding over 85% market share of color‑change films. Limitations include poor conformability, no scratch‑healing feature and weak UV‑resistance. Budget unbranded PVC wraps normally age rapidly within 1‑2 years, while premium‑formulated PVC with UV absorbers can achieve a 3‑year anti‑aging lifespan. Primary function: Cosmetic color‑change, basic paint isolation, no self‑healing performance.

### Phase 4. Upgraded PET Wrap Films | 2016‑2021

PET (Polyethylene Terephthalate) was introduced as an improved alternative to traditional PVC wraps. PET substrate delivers superior dimensional stability, ultra‑smooth film surface and far fewer orange‑peel defects, plus richer color saturation. However, PET is a stiffer material, making complex curved‑surface installation harder. PET still provides **no thermal scratch‑repair function**. PET quickly became a mainstream mid‑range decorative wrap material. Primary function: High‑end cosmetic customization, premium surface finish, decoration‑oriented.

### Phase 5. Colored‑TPU Wrap: Decoration + Paint Protection, Dual‑Function Product | 2020‑Present

With breakthroughs in aliphatic yellow‑resistant TPU coating technology, manufacturers broke the old boundary that “TPU was only for invisible clear‑PPF”. Colored‑TPU wrap films were created. This new‑generation material combines the thermal self‑healing, stone‑chip resistance and long‑term anti‑aging advantages of clear TPU paint‑protection film, alongside full‑body color‑changing aesthetics. Colored‑TPU wrap represents the premium end of today’s vehicle‑wrapping market, completing the full‑industry evolution path: window insulation → paint protection → cosmetic wrap → protection‑plus‑color‑change. Primary function: Dual‑purpose, decorative recoloring + full‑function paint protection with scratch self‑healing

## TPU Colored Film FAQs

What is TPU paint protection film?

TPU paint protection film is a high-performance thermoplastic polyurethane material designed for automotive surface protection. It features excellent flexibility, thermal self-healing, anti-yellowing, scratch resistance and long-term weather resistance. It can effectively protect original car paint from scratches, stone chips, UV rays and chemical corrosion.

Does TPU film really have self-healing function?

Yes. Our TPU PPF adopts advanced thermal self-healing coating. Minor fine scratches and swirl marks can disappear automatically under natural sunlight or warm water temperature, restoring the film surface to smooth and glossy condition.

Will there be glue residue when removing TPU film?

Our TPU film adopts high-quality stable glue system with strong initial adhesion and balanced viscosity. When removed within the service life, it can be peeled off cleanly without residual glue, no damage to the original paint.

Can TPU film resist stone chips and road debris?

Yes. The multi-layer composite structure provides excellent toughness and impact resistance. It can effectively buffer the impact of road gravel, sand flying stones and minor collisions, avoiding permanent damage to the car paint.
