Description

technical field [0001] The invention belongs to the technical field of polyurethane materials, in particular to an antibacterial and flame-retardant flexible polyurethane foam. Background technique [0002] Flexible Polyurethane Foam (Flexible Polyurethane Foam, referred to as polyurethane soft foam) refers to a type of flexible polyurethane foam with a certain degree of elasticity, and it is the most widely used polyurethane product. The main products are High Resilience Foam (HRF), Block Sponge, Slow Resilience Foam, Integral Skin Foam (ISF), and semi-rigid energy-absorbing foam. The cell structure of polyurethane flexible foam is mostly open, with low density, good elastic recovery, sound absorption, breathability, heat preservation and other properties, mainly used as furniture cushion materials, vehicle seat cushion materials, various soft cushion layers Press composites. Soft foam is also used as filter material, sound insulation material, shockproof material, decora...
