Boat Buoyancy Material
Sondor's sva 33 has been successfully evaluated by the sabs against the requirements of iso 12402-7: 2007 section 4.8 which details the requirements for personal floatation device materials and components, with specific reference to foam floatation material.. Another approach has been to use buoyancy bags filled with air ("air bags"). these must be well secured in the boat so that they can't move, especially in an emergency or if there is some damage done to the boat, and they should be made of a material that will not puncture easily and not leak.. Showing the mixing and expansion of 2 lb pu buoyancy foam. this 2 part polyurethane flotation foam is used to add reserve buoyancy to boats, as well as stiffen hulls and provide insulation..
