| 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 |
