Description

technical field

[0001] The invention relates to the technical field of polyurethane foam production equipment, in particular to a foaming equipment with good foaming effect for polyurethane foam production. Background technique

[0002] Polyurethane foam is made of isocyanate and hydroxyl compound through polymerization and foaming. According to its hardness, it can be divided into two types: soft and hard. Among them, soft is the main variety. Generally speaking, it has excellent elasticity, softness, Elongation and compressive strength; good chemical stability, resistant to many solvents and oils; excellent wear resistance, 20 times larger than natural sponge; and excellent processability, heat insulation, adhesion and other properties, is a kind of Cushioning material with excellent performance, but the price is relatively high. Polyurethane foam is generally only used for cushioning packaging or cushioning materials for high-end precision instruments, valuable instrument...
