What Is High Density Pearl Cotton

What is high density pearl cotton? High-density pearl cotton shock-proof packaging material is a new type of polyethylene product. EPE pearl cotton does not pollute the environment and can be recycled repeatedly. Therefore, it is a new type of packaging material with its own characteristics. With the development of e-commerce and the continuous progress of products, high-density pearl cotton shock-proof packaging materials will be more widely used in packaging and filling materials. Because the high density white EPE pearl cotton shock-proof packaging material is a new type of environmental protection packaging, its good characteristics, more and more people understand, so its use will continue to expand and innovation. Especially in packaging and other industrial materials, it is better than the traditional material performance, lower cost, higher grade, elegant generous, better results.

High density pearl cotton

The high-density pearl cotton shock-proof package is formed through physical foaming. The selection of foaming auxiliary agent, anti-shrinkage agent, nucleating agent and temperature control requirements are relatively harsh. When choosing foam agent, requirements in the condition of scale best into gas, convenient liquefaction under pressurized conditions, the second is for foaming agent is a colorless, odorless, non-toxic, no corruption 鉵 sex, foaming leave no residue in the polymer, low in polyethylene melt infiltration excretion rate, low steam at room temperature, high volatile and low molecular weight and density is big, the unit volume of gas capital is low, the extrusion condition can dissolve in polyethylene, elevated temperature and pressure, dissolved quantity change increases, easy to make the foam molding for foam density is small.

High density EPE

Compared with ordinary EPE pearl cotton shockproof packaging materials, high density EPE pearl cotton shockproof packaging materials not only have higher density, excellent elasticity and resilience, more delicate surface, not easy to deformation, high density EPE pearl cotton to overcome the traditional packaging materials fragile, deformation, poor recovery.
