Technical Parameters 1. Material: High Density Polyurethane closed cell foam with high-density polyethylene as body; Color: orange; Size: outer diameter ≤718 mm, inner diameter ≤458 mm; handle: diameter ≥10.3 mm, length ≥3090 mm; The reflective material: The reflective material with 5 cm width is assembled on both sides of the sample at equal intervals. 5. Weight: ≤2.64 KG6. Temperature cycling: at-30 °C and + 65 °C, after 10 cycles of tests, there is no sign of stiffness reduction at high temperature and no sign of damage, drop performance: The upper end of the product shall be suspended by means of a release device so that the lower end shall be at the height or 30 m intended to be stored on board the ship at the least load, take the larger one and drop it into the water without damage. Another product over the release device hanging, so that its lower end at the height of 2M and dropped on the cement floor 3 times without damage 8, fire performance: tested, not Burning 9, floating performance: product hanging not less than 14.5 kg of iron, floating in water, it can float 24h10, strength performance: use a 50mm wide belt to hang the product, then use the same belt to hang the 90kg mass object under it, 30min later, no breakage, crack or permanent deformation 11. Oil Resistance: immersed horizontally in 100MM pressure head diesel oil at room temperature for 24 hours, no signs of damage, such as shrinkage, cracking, swelling, etc. , decomposition or change in mechanical properties 12. Implementation Standard: GB 4302-2008 Lifebuoy
