One of the most important types of life jackets of lifesaving equipment

China has long lacked the product standards and test method standards for foams for life jackets. In production, only chose foam plastics based on the subjective judgment of technicians, so the quality of life jackets is very different. With the development of EVA, chemically cross-linked PE, and rubber-plastic blended high-foam soft closed-cell foam production technology, lightweight and soft closed-cell foam has become the main floating material of current life-saving equipment, to a certain extent replaced the traditional floating material kapok. Soft closed cell foam has become a major staple of life jacket float materials.

Foam plastic for life jackets should have a low compression stiffness and a high compression elastic recovery rate to ensure that the user has good fit, comfortable wearing, soft hand feeling, and stable buoyancy. The compression-resilient energy test method for foam for life jackets is operability, avoids human error, and has good consistency with expert judgement. On this basis, product standards and test method standards for foams for life jackets can be formed.
