Product Description
The sponges used in the sponge box mainly include EVA, PU, EPE, anti-static PE , etc. EVA foam: It has good softness, rubber-like elasticity, good surface gloss, good chemical stability, good anti-aging and ozone aging resistance, and non-toxic. PU sponge: heat preservation, heat insulation, sound absorption and shock absorption are very outstanding, and it also has the advantages of flame retardancy and air permeability, and has a very wide range of applications. Excellent packaging effect for microelectronic chips and electronic spare parts.
EPE pearl cotton: a new type of environmentally friendly packaging material. It is composed of numerous independent bubbles produced by physical foaming of low-density polyethylene, which overcomes the shortcomings of ordinary foamed rubber such as fragility, deformation and poor recovery. It has many advantages such as water and moisture resistance, shock resistance, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, and strong impact resistance. It also has good anti-aging performance and is an ideal substitute for traditional packaging materials.
Anti-static PE foam: a new type of environmentally friendly material, non-toxic, tasteless, sound-proof, sound-absorbing, heat-insulating, no pollution to the atmosphere when incinerated, good resilience, softness and thickness can be adjusted at will, and light weight.
