Differentiating PVC Coated Tarpaulin Fabric and PVC Laminated Fabric

Differentiating PVC Coated Tarpaulin Fabric and PVC Laminated Fabric

While both utilize Polyvinyl Chloride (PVC) for enhanced performance, PVC Coated Tarpaulin Fabric and PVC Laminated Fabric are distinct materials due to their manufacturing processes, resulting properties, and primary applications.

1. Manufacturing Process:
* PVC Laminated Fabric: This is a composite material created by bonding (laminating) two distinct fabric layers, or one or more layers of film to a fabric substrate. The goal is to combine the advantageous properties of the individual materials.
* PVC Coated Tarpaulin Fabric: This involves applying a liquid PVC coating directly onto a base fabric (typically fiberglass, glass cotton, or synthetic fiber) using specialized processes (e.g., knife coating, calendering). The coating penetrates and encapsulates the fabric weave, forming a protective surface layer.

2. Key Characteristics:
* PVC Laminated Fabric:
* Represents a novel fabric type synergizing the benefits of both film and fabric components.
* The PVC film component can be produced via various methods (casting, blow molding, calendering, coating) prior to lamination.
* Key properties often include: High elasticity, excellent toughness, superior abrasion resistance, good low-temperature flexibility, and environmental friendliness/non-toxicity.

3.PVC Coated Tarpaulin Fabric:
* Characterized by robust protective functionalities: Waterproof, Flame Retardant, Mildew Resistant, Cold Resistant, Corrosion Resistant (often marketed as "3-proof" or "5-proof" fabric).
* Offers exceptional durability: High resistance to weathering/UV degradation and aging.
* Features easy cleanability and thermal properties: High-temperature resistance (up to 180°C) and good thermal insulation.

4. Primary Applications:
* PVC Laminated Fabric:
* Predominantly used in inflatable products and flexible containers requiring airtightness, strength, and flexibility. Key applications include:
* Inflatable life jackets & buoyancy compensators (BC Jackets) for diving
* Life rafts & Inflatable boats (dinghies, tenders)
* Inflatable tents & shelters
* Military inflatable self-inflating mattresses/beds
* Massage air bladders/cells
* Medical anti-decubitus (pressure sore prevention) mattresses
* Technical/Professional waterproof backpacks and bags.

5.PVC Coated Tarpaulin Fabric:
* Primarily employed for heavy-duty protective covers, shelters, and industrial textiles where durability and environmental protection are paramount. Key applications include:
* Tarpaulins and covers for train/truck freight, grain silos, wharves/ports, and warehouses (primarily leveraging waterproofing).
* Shelters: Drilling rig enclosures, various tent types, mine ventilation ducts (utilizing waterproofing, fire resistance, cold protection, corrosion resistance).
* Thermal insulation wraps for pipes and equipment.
* Fireproof tape substrates.
* Fire safety products: Welding blankets (e.g., shipbuilding), fire barrier curtains, fire-resistant tents.
* Architectural membranes for tensile structures in landscape/construction projects.
* Temporary structures (tents, marquees).
