| Material structure | Usually closed-cell polyethylene foam; may be physically or chemically cross-linked. | Cross-linked polyethylene foam with a fine, uniform closed-cell structure. | Closed-cell ethylene-vinyl acetate copolymer foam. | Confirm the exact resin, cross-linking method, and cell structure in the technical data sheet. |
Typical density kg/m³ | Approximately 25–80 | Approximately 30–100 | Approximately 45–150 | Lower density generally improves floating efficiency, while higher density can improve firmness and durability. |
Theoretical gross buoyancy Approximate lift before product weight | About 920–975 kg of water displacement per m³ of foam | About 900–970 kg of water displacement per m³ of foam | About 850–955 kg of water displacement per m³ of foam | Actual usable load is lower because it must include the mat, fittings, fabric, users, and a safety reserve. |
| Water absorption | Very low when the cells remain closed; damaged edges can allow water entry. | Very low due to the closed-cell, cross-linked structure. | Very low in properly manufactured closed-cell grades. | Request water-absorption test results for the finished mat, not only for the raw foam. |
| Surface grip | Moderate; improves with textured embossing or a non-slip laminated surface. | Moderate to high; fine-cell surfaces can provide a stable feel, especially with texture. | High potential for grip because EVA can be formulated with a softer, more tactile surface. | Do not select by resin alone; compare wet slip performance of the finished surface. |
| Flexibility and comfort | Good flexibility with a light, resilient feel. | Good resilience and dimensional stability; commonly suitable for repeated folding or rolling. | Very good cushioning and soft-touch comfort, depending on grade. | EVA is often preferred for comfort-focused products; XPE is often preferred when shape retention matters. |
| Tear and compression resistance | Good in medium- and high-density grades; performance varies significantly by formulation. | Generally good resilience, tear resistance, and recovery after compression. | Good cushioning performance; softer grades may show more surface wear or compression set. | For rental or commercial use, prioritize compression set, tear strength, and seam durability. |
| UV and weathering | Requires UV stabilizers for prolonged outdoor exposure. | Requires UV stabilizers and suitable surface protection for long-term sunlight exposure. | Requires UV stabilization; color and formulation affect outdoor durability. | Ask for accelerated weathering results and confirm the intended service life in sunlight. |
| Recyclability | Generally recyclable as polyethylene where suitable collection and reprocessing are available. | More difficult to recycle mechanically because cross-linking prevents normal melt reprocessing. | Technically recyclable as EVA in specialized streams, but collection and sorting are limited. | Use mono-material construction, avoid permanent mixed-material laminates, and request a verified recycling pathway. |
| Typical cost position | Often the most economical option, depending on density and processing. | Usually mid-range to premium because of cross-linking and tighter process control. | Ranges from mid-range to premium depending on vinyl acetate content, density, and surface finish. | Compare total landed cost, expected service life, warranty risk, and required surface treatments. |
| Best wholesale fit | Large-volume, cost-sensitive floating products where basic buoyancy is the main requirement. | Commercial, rental, and premium products requiring durability, dimensional stability, and repeated use. | Comfort-oriented mats requiring a soft feel, attractive finish, and potentially higher grip. | Choose according to target price, usage frequency, comfort expectations, and end-of-life requirements. |
