Differences Between EVA and EPS Fishing Floats (Buoys)
EVA and EPS are the two most common foam materials used for makingfishing floats(net buoys). Their main difference is: EVA is known for durability and high performance, suitable for harsh professional environments; while EPS is known for being economical and providing high buoyancy, ideal for large-scale, cost-sensitive applications.
Here is a direct comparison of their core differences in a table:
Feature | EVA Float (Ethylene-Vinyl Acetate) | EPS Float (Expanded Polystyrene) |
Core Material | Ethylene-Vinyl Acetate, a high-end foam material | Expandable polystyrene, commonly known as "styrofoam" |
Main Advantage | Extremely durable, puncture-resistant, non-absorbent ; very long service life | Low cost, huge buoyancy ; very high cost-performance ratio |
Structural Feature | 100% closed-cell structure with a smooth, dense surface. Even if punctured or cut, it won't absorb water or sink | Formed by compressing foam particles, relatively rough surface. If the outer layer is damaged, it may absorb water and gain weight over time |
Durability | Excellent . UV-resistant, seawater-corrosion-resistant, high-impact-resistant. Not prone to cracking or deforming in harsh sea conditions | Moderate . The surface tends to powder and peel under prolonged sun and seawater exposure, leading to reduced buoyancy |
Typical Uses | Offshore purse seining, deep-sea aquaculture, commercial fishing where high reliability is critical | Inshore cage farming, crab/lobster pot markers, general recreational sea fishing, etc. |
Lifespan & Cost | Higher cost, but very low maintenance. High-quality products retain over 85% of buoyancy after 10 years | Low cost, suitable for short-term or large-scale replacement. Consumable product, expected lifespan around 8-10 years |
EVA Floats: The "Durability King" for Professional Use
EVA floats are the top choice for commercial fishing and demanding environments.
- Extremely Durable:
- Waterproof:100% closed-cell foam technology
- Low Drag:
They are widely used in offshore purse seining, deep-sea aquaculture, and similar demanding applications.
EPS Floats: The High-Buoyancy "Value Choice"
EPS floats are the most widely used and cost-effective choice among fishermen.
- Huge Buoyancy: 170-300 kg (375-660 lbs)
- Low Cost:
- Lightweight & Easy to Use:
They are most commonly used in inshore cage farming, setting gill nets, crab pot marking, and budget-constrained projects.
How to Choose?
The choice mainly depends on your specific application scenario and budget.
Choose EVA floats if you:
- Are engaged in offshore or deep-sea fishing
- Need maximum service life
- Require high abrasion and impact resistance
Choose EPS floats if you:
- Are working in inshore waters, lakes, or reservoirs
- Are involved in large-scale aquaculture tight budget control
- Mainly need to statically hold
