PVC Rigid Sheet(UV Stabilized) - Weatherproof, Printable


Field Notes on PVC Rigid Sheet(UV Stabilized): What Buyers Actually Care About in 2025

I’ve walked enough factory floors to know: not all rigid PVC is the same, and UV is the quiet killer. In outdoor signage, chemical enclosures, even farm infrastructure, sunlight can chalk and embrittle basic PVC in a year or two. That’s why buyers keep asking for PVC Rigid Sheet(UV Stabilized)—and, to be honest, for good reason. Below is a condensed insider’s guide based on current projects, lab data, and what many customers say after six months in the field.

PVC Rigid Sheet(UV Stabilized) - Weatherproof, Printable
Manufactured in Baoding, Hebei (No.316 Pingan West Street, Shunping County, 072250)

Industry trends: durability over headline specs

Outdoor plastics buyers are pivoting from peak strength promises to retention metrics: how much tensile and color performance remains after UV exposure. Surprisingly, procurement teams now ask for QUV test curves, not just MSDS sheets. Also trending: Ca-Zn stabilization (RoHS-friendly), matte anti-glare surfaces for signage, and tighter color matching (RAL/Pantone) in small batches.

Key applications (from recent orders)

  • Outdoor signage, display boards, wayfinding systems
  • Facade cladding, equipment guards, rooftop duct skins
  • Chemical tank liners, splash guards (acid/alkali areas)
  • Cleanroom tool panels, electrical enclosures (low smoke/halogen concerns vary)
  • Agriculture partitions, livestock housing panels

Product specifications (real-world ranges)

Parameter Typical values / options
Thickness 1–30 mm standard; custom up to ≈50 mm on request
Width by thickness 1–3 mm: 1000–1300 mm; 4–20 mm: 1000–1500 mm; 25–30 mm: 1000–1300 mm; 35–50 mm: ≈1000 mm (special-order)
Length / standard sizes Any length; common: 1220×2440 mm, 1000×2000 mm, 1500×3000 mm
Surface / colors Glossy, matt, embossed; dark grey (RAL7011), light grey, black, white, blue, green, red, custom colors
Density ≈1.40 g/cm³ (PVC-U)
Mechanical (ref.) Tensile 45–55 MPa (ASTM D638); Flexural 80–100 MPa (ASTM D790); Izod ≈4–8 kJ/m² (ASTM D256) — real-world use may vary
UV performance QUV (ISO 4892-2 / ASTM G154): 1000 h, ΔE typically <5; tensile retention ≈85–95% depending on color/finish

Process flow (how it’s made, briefly)

Materials: PVC resin (K≈57–67), Ca-Zn heat stabilizers, UV absorbers, rutile TiO₂, impact modifiers, lubricants, pigments. Methods: high-intensity compounding → twin-screw extrusion → calendaring/pressing → surface texturing (gloss/matt/emboss) → cooling → sizing → trimming. Tests: ASTM D638/D790/D256, ISO 62 (water absorption), ISO 4892-2 (UV), dimensional tolerance checks, color ΔE against RAL/Pantone. Service life: outdoors ≈5–10 years (temperate); tropical/high-UV zones trend lower unless thickness and TiO₂ loading are increased.

Why customers pick PVC Rigid Sheet(UV Stabilized)

  • Better colorhold and less chalking versus standard PVC
  • Rigid, easy to fabricate (cut, rout, bond, thermoform at modest temps)
  • Chemical resistance against acids/alkalis commonly found in plants
  • RoHS/REACH-friendly Ca-Zn systems available

Vendor snapshot (what to look for)

Vendor MOQ Lead time Tolerance UV warranty Certifications Customization
Lida Plastic (Hebei) ≈1–2 tons 10–20 days Thickness ±0.2–0.5 mm (by gauge) Project-specific (ask for QUV data) ISO 9001, RoHS/REACH statements Color, emboss, cut-to-size
Generic importer Varies Stock-dependent Mixed Often unspecified Basic CoC Limited
Local fabricator Low Quick Good on cut parts Depends on source Fabrication certs Excellent post-processing

Customization tips

  • For coastal installs, ask for higher TiO₂ and darker greys; it seems that color drift is lower.
  • Request QUV-B 313 nm and QUV-A 340 nm curves; different spectra matter.
  • Matte/embossed surfaces reduce glare and scuff visibility on signage.

Micro case studies

  • Transit signage, SE Asia: after 2000 h QUV-A, ΔE≈3.6 and tensile retention ≈90%; field check at 12 months showed no chalking.
  • Plating room splash guards: alkaline mist exposure; panels held gloss and dimensional stability, weekly wipe-down only.

Compliance note: UL 94 V-0, food-contact, or specialized cleanroom grades can be supplied on request with supporting test reports; always verify per application.
