PMMA film, with its excellent optical properties and extreme environmental resistance, has become a core material in the field of outdoor advertising. The specific application advantages and technical points are as follows:

1、 Core performance advantages

Optical performance

The light transmittance is ≥ 92% (higher than 91% of glass), ensuring that the advertising image is saturated and distortion free, and the visual impact at night is increased by more than 40%.

Anti UV aging (1000 hour QUV aging test Δ E ≤ 3), long-term use without yellowing or cracking, maintaining the original color of the advertisement.

Environmental protection

The impact resistance strength is 10 times that of glass, and it can withstand the impact of hail with a diameter of 4cm, 23m/s, and strong winds, reducing maintenance costs by 30%.

-Stable temperature range of 30 ℃~80 ℃, suitable for extreme environments such as high cold and coastal salt spray, with a service life of over 10 years.

II. Application scenarios of billboards

Giant outdoor advertising board

As a surface protective layer for advertising images, it achieves self-cleaning function through the "lotus leaf effect", reducing rainwater and dust accumulation, and lowering cleaning frequency.

Lightweight characteristics (density 1.18 g/cm ³) reduce building loads and are suitable for large advertising spaces such as shopping mall exterior walls and sports venue roofs.

Transportation Hub Advertising System

Used for highway variable message boards (VMS), with a bending resistance of over 50000 times, suitable for curved installation requirements (such as tunnel curved ceilings).

Combined with microprism reflection technology, the nighttime recognition distance is increased by 50%, suitable for tunnel signage and toll station signs.

Commercial space advertising carrier

Retail store window protectors enhance product display transparency while providing scratch resistant protection to the glass surface.

The digital signage screen protection layer and anti glare design ensure clear and visible images under strong light.

3、 Functional Expansion Design

Special protection requirements

UV resistant customized film (such as Lorica protection solution) blocks 99% of UV rays and protects sensitive printing pigments from fading for a long time.

B1 level flame retardant certification, with self extinguishing characteristics upon ignition to reduce the risk of fire spread.

Processing and installation optimization

Support laser cutting and thermoforming (precise temperature control of 130 ℃± 5 ℃) to achieve seamless curved surface shaping of irregular billboards.

Snap on lightweight installation, with a 50% increase in efficiency compared to traditional glass installation.

IV. Application Risk Avoidance Guidelines

Scene

Key parameters

Risk control measures

Billboards in high-temperature areas

Hot deformation temperature ≥ 95 ℃

Prevent dark images from absorbing heat and causing local bubbles

High speed reflective signage

Transmittance ≥ 92%

Surface embossing treatment for anti glare

Highly polluted areas

Surface tension>38 mN/m

Maintain self-cleaning by rinsing with clean water every month

Typical case:

The Bund commercial district in Shanghai adopts PMMA film billboards with no fading record for 3 years (2023-2026)

The reflective signage system of Guangzhou Shenzhen Expressway has reduced the accident rate by 15% in rainy and foggy weather (2024 Traffic Management Report)

Through its three core advantages of optical performance, environmental protection, and processability, PMMA film is driving the upgrade of outdoor advertising towards high durability and low maintenance. During implementation, it is necessary to strictly control the hot forming process and prioritize the use of coating models to enhance wear resistance.
