Let me talk about foam first. It is often used for sealing gaps, wide joints, insulation, cracks, cold resistance, heat insulation, sound insulation and moisture resistance. For example, the gap between the ceiling and the partition, the network marketing training of the cavity between the door frame, the window frame, and the wall, the gap between the chimney and the roof, the seal around the ceiling, the wall, the roof pipe and the wall Damages and holes. Can be used for bonding of various materials.
First, the important specificity of foam is its ability to absorb impact loads. When EPS packaging products are subjected to impact loads, the gas in the foam undergoes tightening and staying. It is the external energy that is consumed and consumed. The foam can gradually stop the impact load with minimum negative acceleration, so it can be well shockproof.
Second, light weight is also a serious feature of it. EPS packaging products are partially replaced by gas, and each cubic decimeter volume contains 3-6 million self-sealing vapor bubbles. So it is dozens of times larger than plastic. Now you know why the foam is so easy to use. Its packaging application characteristics and application scope should be understood by us.
