In terms of benefits, first of all, they can maintain stable shapes in high-temperature environments. Whether it is outdoor venues exposed to intense summer sun (such as open squares and parking lots) or indoor scenes close to heat sources (such as around kitchens and near air outlet of shopping mall heaters), PP boards can resist deformation, softening or cracking caused by high temperatures. This prevents the billboards from warping and the pictures from wrinkling due to temperature changes, ensuring the complete presentation of advertising information. Secondly, they improve the durability and safety of billboards. Compared with ordinary plastic or paper billboards, which are prone to surface melting, emitting peculiar smells and even causing safety hazards in high temperatures, the heat-resistant property of PP boards enables them to maintain chemical stability in continuous high-temperature environments, not easy to release harmful substances. At the same time, they reduce the frequency of replacement caused by high-temperature aging, thus lowering the long-term use cost. In addition, they expand the range of application scenarios for billboards. The heat resistance allows PP boards to break through the temperature restrictions of traditional billboards, enabling them to be stably used in high-temperature workplaces (such as factory workshops and restaurant kitchens), outdoor areas in tropical regions, and special positions close to lights and equipment heat sinks, providing more possibilities for advertising placement.
Applications
Firstly, outdoor advertising in high-temperature environments. They can be used for billboards on expressways exposed to direct summer sunlight, fence advertisements in open-air stadiums, and indicative advertisements in sun-exposed areas of scenic spots. Even in high-temperature weather above 40℃, they can maintain a flat appearance and clear pictures. Second, publicity in high-temperature workplaces. In workshops of food processing factories and steel plants, they can be made into billboards for equipment operating procedures and safety warnings, which can withstand the high-temperature environment in the workshops and ensure that the information is clearly readable for a long time. Third, indoor advertising close to heat sources. For example, food promotion boards outside restaurant kitchens and promotional advertisements in shopping malls near heaters or large electronic screens. They avoid deformation and damage caused by heat sources, maintaining the aesthetics and practicality of the advertisements. Fourth, outdoor advertising in tropical regions. In tropical regions with year-round high temperatures, they are used to make street light box advertisements and building exterior wall advertisements, resisting the erosion of continuous high temperatures on the billboards and prolonging their service life.
Comparison of Common Advertising Board Materials
| Material | Physical Properties | Environmental Adaptability | Processing & Printing Characteristics | Cost & Lifespan | Typical Application Scenarios |
| PP Board | Density 0.90-0.91g/cm³, lightweight; moderate rigidity, good bending resistance, resistant to slight impact; weak resistance to heavy pressure | Excellent water resistance (water absorption < 0.01%), suitable for short-term outdoor use (3-6 months) and humid environments; prone to aging under long-term exposure to sunlight, softens above 60℃ | Easy to cut and weld, low processing cost; smooth surface, compatible with UV printing and screen printing, strong pattern adhesion; difficult to process complex shapes | Cost 10-30 yuan/㎡, high cost performance; 1-3 years indoors, <1 year outdoors | Promotional posters, bathroom reminder signs |
| PVC Board | Density 1.3-1.4g/cm³, medium weight; better rigidity than PP board, strong impact resistance | Good weather resistance (1-3 years outdoors), waterproof and moisture-proof, resistant to acid and alkali corrosion; prone to embrittlement at low temperatures and deformation at high temperatures | Cuttable and heat-bendable, good processability; surface suitable for printing and film lamination, high color reproduction; welded joints prone to cracking | Cost 20-50 yuan/㎡; 3-5 years indoors, 1-3 years outdoors | Lightbox panels, fixed shopping mall display boards |
| Acrylic Board | Density 1.18-1.2g/cm³, lightweight; high transparency (92%), good surface gloss, strong impact resistance | Strong weather resistance (3-5 years outdoors), UV-resistant (requires UV stabilizers); not scratch-resistant, prone to scratches | Easy to cut and polish, suitable for laser engraving; bright printing colors, ideal for high-end displays; high processing cost | Cost 80-200 yuan/㎡; 5-8 years indoors, 3-5 years outdoors | Brand image walls, high-end showcase signs |
| Aluminum Alloy Board | Density 2.7g/cm³, relatively heavy; high strength, good rigidity, strong impact and pressure resistance, not easy to deform | Extremely strong weather resistance (5-10 years outdoors), UV-resistant, resistant to high and low temperatures (-40℃ to 80℃), rust-proof | Cutting and bending require professional equipment, high processing cost; surface needs pretreatment (e.g., sandblasting) for printing, average adhesion | Cost 100-300 yuan/㎡; 5-10 years outdoors | Large outdoor billboards, subway light boxes |
| KT Board | Density 0.1-0.2g/cm³, extremely lightweight; very poor rigidity, easy to bend and break, unable to bear weight | Only suitable for dry indoor environments, completely non-waterproof, moisture-sensitive and sun-sensitive, damaged within 1 hour outdoors | Easy to cut (with utility knife), low processing threshold; only suitable for simple inkjet printing, patterns prone to wear | Cost 1-5 yuan/㎡; 1-4 weeks indoors, <1 day outdoors | Temporary exhibition backdrops, short-term notices |
| Aluminum-Plastic Composite Board | Density 1.3-1.5g/cm³, medium weight; combines metal strength with plastic toughness, good bending resistance | Good weather resistance (3-7 years outdoors), UV-resistant, rainproof, stable at -30℃ to 70℃; edges prone to water absorption and bubbling | Cuttable and bondable, better processability than pure metal; surface aluminum layer suitable for spraying and screen printing, good pattern adhesion | Cost 30-80 yuan/㎡; 3-7 years outdoors | Building exterior wall advertisements, medium-sized display boards |
