♦ High strength and light weight advantages
- Excellent tensile strength
The tensile strength of UHMWPE fiber is 15 times that of steel wire and 1.6 times that of aramid, which is able to withstand the violent struggle of fish and the impact of water current in deep-sea fishing.
- Dramatically reduced mass
Its density is only 0.97g/cm³, and the nets made of it are more than 50% lighter than ordinary polyethylene nets, and the same quality can be used to make larger-sized nets and improve fishing efficiency.
♦ Resistance to environmental erosion
- Resistant to seawater corrosion
Chemically inert, it is stable in salt spray environments for long periods of time and can resist seawater corrosion without plating for up to 20 years.
- UV Aging Resistance
By adding light stabilizer and pigment TB composite modification, the fiber strength retention rate after 1500 hours of UV irradiation is still up to 80%, which significantly extends the life of fishing nets.
♦ Biofouling Resistance and Low Water Resistance Design
- Inhibit the attachment of marine organisms
The monofilament knotless weaving process reduces surface gaps and combines with low surface energy characteristics to effectively reduce the adhesion rate of algae and shellfish and improve seawater exchange efficiency.
- Reduce water flow resistance
The water resistance coefficient of lightweight knotless gear is only 0.35 (0.5-0.7 for traditional knotted nets), which reduces the fuel consumption of fishing vessels by 15%-20%.
♦ Application Examples
- Deep-sea trawling:
UHMWPE nets catch high-value fish such as tuna, with a 30% increase in tear resistance;
- Aquaculture seine nets:
In Norwegian salmon farms, monofilament knotless nets increase the survival rate of fry to 98%;
- Pelagic Fishing:
The adoption of this gear by the Chinese pelagic fleet resulted in a 25% increase in single-trip catch and extended the operating range to 3,000 meters deep;
♦ Comprehensive performance comparison (with conventional materials)
| Characterization | UHMWPE Fishing Net | Nylon Fishing Net | Steel Fishing Net |
| Service Life | ≥20 years | 5-8 years | Regular plating maintenance required |
| Tensile Strength | 30-40cN/dtex8 | 5-8cN/dtex | – |
| Maintenance Costs | Low(no corrosion protection required) | Medium (needs anti-aging treatment) | High (anti-rust treatment) |
With these properties, UHMWPE nets have become a core material in the deep-sea economy to improve fishing efficiency and reduce operating costs.
