UPVC Roof Sheets

ASA UPVC Roof Sheets are a new generation of lightweight, eco‑friendly roofing materials designed for modern construction. They are environmentally friendly, energy‑saving, and fully recyclable. Manufactured primarily from high‑quality PVC resin powder and calcium powder, with the addition of heat stabilizers and impact modifiers, the surface is coated with an ASA ultra‑weather‑resistant film for superior durability.

ASA UPVC roof sheets combine strength, aesthetics, and long‑term performance. Key features include being lightweight yet high‑strength, waterproof, moisture‑proof, corrosion‑resistant, fire‑retardant, soundproof, and thermally insulated. They are widely used for flat‑to‑pitched roof conversions in development zones, farmers’ markets, workshops, warehouses, shopping malls, residential communities, high‑end villas, rain shelters, sunshades, and traditional‑style buildings.

Product Advantages

Superior Weather Resistance

ASA UPVC roof sheets are manufactured using high‑quality, weather‑resistant engineering resin. ASA (Acrylonitrile Styrene Acrylate) is a copolymer of styrene, acrylonitrile, and acrylic rubber that significantly enhances durability. In xenon lamp aging tests—used to simulate prolonged sunlight exposure—ASA materials show no significant discoloration or degradation even after 1,000–2,000 hours.

Self‑Cleaning Properties

The dense and smooth surface of ASA UPVC roof sheets prevents dust accumulation. Featuring a natural lotus‑leaf effect, rainwater easily washes away dirt, keeping the roof clean and streak‑free after rainfall.

Impact Resistance & Low‑Temperature Durability

ASA UPVC roof sheets offer excellent impact resistance, even in low‑temperature conditions. A 1 kg steel hammer dropped from a height of 1.5 meters does not cause cracking. After 10 freeze‑thaw cycles, the sheets remain free from bulging, bubbling, peeling, or cracking.

Excellent Corrosion Resistance

ASA UPVC roofing sheets can withstand exposure to salt, alkalis, and acids with concentrations below 60% for up to two hours without chemical reactions. This makes them ideal for coastal areas and regions affected by acid rain.

Eco‑Friendly & Sustainable

ASA UPVC roof sheets are certified under China’s Environmental Labeling Product Certification. At the end of their service life, they are fully recyclable, supporting environmental sustainability.

Product Composition & Material Analysis

• PVC Resin Powder – Polyvinyl Chloride (PVC) resin powder is one of the world’s most widely used synthetic plastics and serves as the primary raw material for UPVC roof tiles.

• Calcium Powder – High‑purity ultrafine calcium carbonate with 96–98% whiteness and over 97% calcium content, used to strengthen the tile structure.

• ASA Ultra Weather‑Resistant Film – A surface coating that enhances weather resistance, UV protection, anti‑aging properties, chemical corrosion resistance, color retention, and self‑cleaning ability.

• PVC Heat Stabilizer – Reduces decomposition during processing and improves overall resin performance.

• CPE / ACR Impact Modifiers – Improve impact resistance, toughness, and durability.

• Stearic Acid – Acts as an internal lubricant to improve processing smoothness.

• PE Wax – Functions as an external lubricant, ensuring smooth surface finish and easy release during manufacturing.

• Titanium Dioxide (TiO₂) – Enhances whiteness, opacity, UV resistance, and overall durability.
