In the world of protective fabrics, PVC Coated Tarpaulin and PVC Laminated Tarpaulin are two popular variants of PVC tarpaulin, each with unique characteristics that make them suitable for different scenarios. The key to selecting the right variant lies not only in understanding their material differences but also in aligning their performance with industry standards-international benchmarks like ISO 8095:1990 (E) and Chinese standards such as BB/T 0037-2012 and GB/T 16741-1997-that define quality, safety, and usability. Reevoo Industry, a seasoned manufacturer with a full range of PVC tarpaulin products, helps clients navigate these differences and standards to select the optimal material for their projects, ensuring compliance without sacrificing functionality.
PVC Coated Tarpaulin: Standards-Driven Durability for High-Stress Applications
PVC coated tarpaulin is manufactured by directly coating PVC resin onto a polyester base fabric (via knife coating or spread coating), creating a tight bond that delivers exceptional tensile strength and weather resistance. This process is explicitly governed by ISO 8095:1990 (E), which specifies that coated fabrics for tarpaulins must have a coating thickness of 0.3–1.5mm (adjustable per client needs) and pass adhesion tests (no coating separation after 100 flex cycles). Reevoo's PVC coated tarpaulin exceeds these requirements, with a coating thickness tolerance of ±0.01mm (vs. ISO 8095's ±0.02mm) and adhesion strength of 30N/25mm (vs. the standard's minimum of 20N/25mm), as verified by SGS testing.
In China, PVC coated tarpaulin is classified under BB/T 0037-2012, which divides 涂覆布 (coated fabrics) into six classes (A-F) based on warp/weft tensile strength:
Class A: ≥1,000N/50mm (light-duty, e.g., garden covers)
Class B: ≥1,200N/50mm (medium-duty, e.g., temporary shelters)
Class C: ≥1,350N/50mm (general industrial use)
Class D: ≥1,600N/50mm (transportation covers)
Class E: ≥2,250N/50mm (construction barriers)
Class F: ≥2,750N/50mm (heavy-duty, e.g., mining covers)
Reevoo's PVC coated tarpaulin is available in Classes C to F, with Class F variants complying with GB/T 16741-1997's G-class requirements (tensile strength ≥3,500N/50mm) for extreme heavy-duty use. For example, Reevoo's Class F coated tarpaulin is used in construction sites across China, meeting BB/T 0037-2012's flame resistance (oxygen index ≥27% per GB/T 5454) and low-temperature performance (-25℃ no cracks) to withstand harsh outdoor conditions. Additionally, the material's water resistance (20kPa per HG/T 2582, a test method referenced in BB/T 0037-2012) ensures it remains waterproof even during heavy rain-critical for protecting building materials.
PVC Laminated Tarpaulin: Flexibility Aligned with Specialized Standards
PVC laminated tarpaulin, by contrast, is produced by laminating a thin PVC film onto both sides of a base fabric using heat or adhesive, resulting in a softer, more flexible material. While it shares some baseline standards with coated tarpaulin (e.g., ISO 8095:1990's water resistance and color fastness), it is often governed by specialized standards for flexible applications. For instance, T/ZZB 2754-2022 (Polyethylene Woven Laminated Tarpaulins), a Chinese group standard, specifies requirements for laminated fabrics used in light-duty applications, such as inflatable products and temporary covers. This standard mandates a minimum tear strength of 50N (vs. ISO 8095's 80N for coated fabrics) and a flexibility rating of "no cracks after 1,000 folding cycles" (tested per GB/T 20284), reflecting the material's focus on maneuverability over heavy-duty strength.
Reevoo's PVC laminated tarpaulin complies with T/ZZB 2754-2022 and ISO 8095:1990's lower-tier requirements, making it ideal for applications that prioritize flexibility. For example, in the recreational industry, it is used to manufacture inflatable bounce houses, where its soft texture (Shore A hardness of 60±5, per ISO 868) and compliance with T/ZZB 2754-2022's "no toxic additives" requirement (per GB 6675 for children's products) ensure safety and usability. In the advertising sector, it serves as textile banners, meeting ISO 8095's color fastness to light (Class 4 per ISO 105-B02:1988) to prevent fading under outdoor exposure.
For regional markets, Reevoo's laminated tarpaulin also adheres to standards like MS 79:1990, which requires laminated fabrics to have a minimum peel strength of 15N/25mm (tested per BS 3424, referenced in MS 79:1990). Reevoo's product exceeds this, with a peel strength of 20N/25mm, ensuring the PVC film does not separate from the base fabric during handling-critical for banner installation and inflatable product inflation.
Key Standards for Comparative Selection
To help clients choose between coated and laminated tarpaulin, Reevoo provides a clear framework of standard-driven performance metrics:
| Performance Metric | PVC Coated Tarpaulin (Class F, BB/T 0037-2012) | PVC Laminated Tarpaulin (T/ZZB 2754-2022) | Governing Standard |
|---|---|---|---|
| Tensile Strength (Warp/Weft) | ≥2,750N/50mm | ≥800N/50mm | BB/T 0037-2012; T/ZZB 2754-2022 |
| Tear Strength | ≥120N | ≥50N | GB/T 13489; T/ZZB 2754-2022 |
| Water Resistance | 20kPa (24h no leakage) | 10kPa (24h no leakage) | HG/T 2582; ISO 8095:1990 |
| Low-Temperature Performance | -25℃ (no cracks) | -15℃ (no cracks) | FZ/T 01007; T/ZZB 2754-2022 |
| Flexibility (Folding Cycles) | 500 (no cracks) | 1,000 (no cracks) | GB/T 20284; T/ZZB 2754-2022 |
This table, rooted in industry standards, helps clients match their application needs to the right material. For example, a logistics company requiring truck covers would select Reevoo's Class F coated tarpaulin (complying with BB/T 0037-2012 and GB/T 16741-1997) for its high tensile strength, while an event planner needing portable banners would choose laminated tarpaulin (complying with T/ZZB 2754-2022) for its flexibility.
Reevoo's expert team further supports clients by providing custom compliance packages, including third-party test reports (SGS, CNAS-accredited labs) verifying adherence to selected standards. For clients unsure of their needs, Reevoo offers free product samples for in-house testing-e.g., a construction firm can test the coated tarpaulin's flame resistance per BB/T 0037-2012, while an inflatable manufacturer can evaluate the laminated tarpaulin's flexibility per T/ZZB 2754-2022. This commitment to standards and client education ensures that every Reevoo customer selects a PVC tarpaulin variant that balances performance, compliance, and cost-effectiveness.
