Core Mechanical Properties

The Life Jacket Crotch Strap Webbing has a 6,000-lb breaking strength, far exceeding the life jacket safety standard (industry standard ≥3,000 lbs), providing sufficient safety redundancy for water rescue; its elongation <7% ensures no stretching or loosening of the crotch strap after life jacket wearing, avoiding life jacket displacement and falling off in water; it has excellent water immersion resistance, with mechanical performance attenuation ≤3% after water immersion.

Environmental Adaptability

It is water immersion-resistant and salt spray corrosion-resistant (complying with ASTM B117 salt spray tests), adapting to water rescue scenarios such as oceans, lakes, and rivers; it resists UV rays and damp-heat aging, not prone to aging and embrittlement during long-term outdoor storage and use; it can withstand temperatures from -10℃ to 85℃, maintaining safety performance in normal-temperature and low-temperature waters; environmentally friendly materials have no odor and no irritation to human skin.

Core Functions

As the core fixing component of life jackets, it is mainly used in water rescue, maritime operations, and water sports scenarios, such as ship life jackets, fire rescue life jackets, and surfing life jackets. It firmly fixes life jackets to the human crotch through high load-bearing and low elongation characteristics, preventing life jacket displacement and falling off in water, and ensuring the life safety of people falling into water.

Product Advantages

Safety Redundancy Advantage

Breaking strength far exceeds industry standards, with stable performance after water immersion and a high safety factor;

Anti-Falling Off Advantage

Low elongation ensures tight and non-loose wearing, avoiding life jacket displacement and falling off in water;

Human-Friendly Advantage

Moderate webbing flexibility ensures comfortable wearing with no pressure, no skin irritation, suitable for long-term wearing.

This Life Jacket Crotch Strap Webbing, with "ultra-high safety redundancy + anti-falling off" as the core, accurately solves the safety pain points of life jacket fixing in water scenarios.

Its water immersion and salt spray resistance adapt to diverse water environments.

And its comfortable wearing design improves use experience, providing a life jacket supporting solution of "safe and reliable, durable and adaptable, and comfortable and friendly" for shipping, fire protection, and water sports industries.
