The present invention relates to a float made by foaming a mixture of ethylene-vinyl acetate copolymer (EVA) and polyethylene (PE) in one foaming step. Specifically, the present invention relates to a float manufactured by foaming a mixture of EVA and PE in one foaming process. Accordingly, the present invention facilitates easy manufacturing of a float and prevents the formation of gaps caused by the assembly process used to make existing floats, such that watertight properties and durability are improved.
본 발명은 EVA 및 PE를 이용하여 한번에 발포된 부자에 관한 것이다. 부연하면, 에틸렌초산비닐 공중합체(ethylene-vinyl acetate copolymer, EVA)와 폴리에틸렌(polyethylene, PE)를 혼합하여 획득된 혼합물을 한번에 발포하여 제조된 부자에 관한 것이다. 이에 따라, 부자로의 제조가 용이하고, 종래의 부자와 같이 조립식으로 구성됨에 따른 틈이 형성되지 않아서, 물이 유입되는 등의 수밀성을 향상시킬 수 있으므로, 내구성의 증진이 기대되는, EVA 및 PE를 이용하여 한번에 발포된 부자에 관한 것이다.
