Ⅰ. Overview of PVC Boat FabricPVC boat fabric i.e., marine fabric primarily made from Polyvinyl Chloride (abbreviated as PVC). In practical applications, PVC is typically compounded with various additives such as stabilizers, lubricants, processing aids, pigments, and impact modifiers to enhance its properties. It is manufactured by coating a canvas base with a PVC-containing adhesive solution, resulting in a smooth surface with 100% waterproof performance. Compared to other material boat fabrics, such as traditional canvas, canvas is relatively durable but lacks good waterproofing. Prolonged contact with water causes it to absorb moisture, become heavy, and affect boat performance. Nylon boat fabric, while lightweight and strong, is deficient in abrasion resistance and UV resistance. In contrast, PVC boat fabric combines excellent waterproofing, abrasion resistance, UV resistance, and other advantages, making it an ideal choice for aquatic applications.

Ⅱ. Overview of TPU Boat Fabric TPU boat fabric primarily consists of Thermoplastic Polyurethane Elastomer (abbreviated as TPU). TPU is a block copolymer synthesized through step-growth polymerization from diisocyanates, polyols, and chain extenders. This material boasts outstanding properties such as high strength, high toughness, oil resistance, water resistance, and weather resistance. The manufacturing process for TPU boat fabric typically involves laminating or coating a TPU film onto a base fabric. The base fabric can also utilize high-strength fiber materials like polyester to enhance the overall mechanical properties. The characteristics of the TPU film impart excellent flexibility to the fabric, allowing it to remain soft even at low temperatures, facilitating folding and storage. Simultaneously, TPU offers exceptional tear resistance and hydrolysis resistance, enabling it to effectively withstand various external forces and water erosion in complex aquatic environments.

Ⅲ. Comparison and Highlighting Advantages of PVC vs. TPU Boat Fabric

Performance Indicator	PVC Boat Fabric	TPU Boat Fabric
Waterproofing	Excellent waterproofing,100% waterproof.	Excellent waterproofing,strong hydrolysis resistance. Better long-term waterproof durability after immersion.
Strength & Abrasion Resistance	Relatively high strength, excellent abrasion resistance, suitable for long-term friction scenarios.	High strength, especially outstanding tear resistance, difficult to puncture with sharp objects.
Weather Resistance	Good weather resistance.	Excellent weather resistance, stable performance under extreme conditions.
Flexibility	Reduced flexibility at low temperatures; may require pre-heating.	Remains flexible at low temperatures, easy to handle.

Ⅳ. Cost and Application Scenario Comparison

Comparison Item	PVC Boat Fabric	TPU Boat Fabric
Cost	Relatively lower production cost, price advantage for mass production.	Expensive material, precise processes, higher cost.
Application Scenarios	Widely used in standard inflatable boats, kayaks, boat covers, etc.	Suitable for high-end water sports equipment, professional research vessel equipment, etc.

 Ⅴ. Advantages Over Other Boat Fabrics

1,Excellent Comprehensive PerformanceCompared to traditional canvas and nylon boat fabrics, PVC and TPU boat fabrics show significant improvements in waterproofing, abrasion resistance, weather resistance, and more. Traditional canvas is prone to water absorption and rotting, while nylon boat fabric has limited UV and abrasion resistance. PVC and TPU boat fabrics effectively overcome these shortcomings, providing more reliable protection for water activities.

2. Strong Processing AdaptabilityBoth fabrics can be processed through various techniques like cutting, sewing, and heat sealing to form marine products of different shapes and specifications. They also integrate well with printing processes, enabling personalized pattern designs to meet diverse user needs.

3, Long Service LifeOwing to their good wear resistance, aging resistance, and other properties, PVC and TPU boat fabrics generally have a longer lifespan than other material boat fabrics. This reduces the cost and hassle of frequent replacements, offering higher cost-effectiveness from a long-term usage perspective.  Ⅵ. Composition and Process Comparison of PVC vs. TPU Boat Fabric

		Coating Process	Apply molten TPU using a doctor blade or roller coating equipment, then cool to form.
Post-Processing Stage	Heat and plasticize to fuse PVC with base fabric, cool for shaping, cut, sew, and process into finished products.	Surface treatment to enhance printing or functional properties, then cut, sew, punch holes, etc., according to order requirements.

Ⅷ. Test Method Comparison for PVC vs. TPU Boat Fabric

PVC Boat Fabric Test Method		TPU Boat Fabric Test Method
Spray Test	Simulate rainfall and observe water penetration on the backside.	Dynamic Water Pressure Test	Simulate water surface fluctuations by applying cyclic water pressure, observe leakage and deformation.
Hydrostatic Pressure Test	Increase water pressure and record the pressure value when leakage occurs.	Long-term Immersion Test	After immersion, check for hydrolysis, swelling; compare hydrostatic pressure before and after immersion.
Tensile Strength Test	Use a tensile testing machine to stretch the sample until break, record maximum force.	Tear Resistance Test (Trouser Tear Test)	Measure force required for complete tearing.
Tear Strength Test	Use a specific shape sample, measure force required to tear.	Bursting Strength Test	Use a spherical plunger to press against a circular sample, record bursting pressure.
