Features of slow rebound polyurethane foam composition:
1. It has a continuous and dense surface layer and a high-strength honeycomb structure with interconnect wall with the obturation rate up to 95%;
2, waterproof, heat preservation, heat insulation, gas insulation, corrosion and other characteristics.
I. material introduction:
PU memory foam products advantages: good shock resistance, flexibility, good resistance to tear strength, hardness, easy adjustment, rebound elasticity, good scalability, bubble good plasticity (can recover after being change shape), can be made into any shape, the material has a kind of both viscous and elastic characteristics, absorb the impact kinetic energy, and can be used repeatedly without deformation. Slow rebound products include U neck pillows, space memory pillows, cushions, earplugs, toys, protectors, fake bread cakes, etc.
