Hazardous Cargo: IMDG Class 9  /  UN No.  2211 

[ Description ]:

It is a kind of Spherical plastic particles with shell made of thermoplastic acrylic polymer and Alkane as core.
expander is a new special additive. It also named microsphere foaming agent . it is a kind of core-shell structure. The shell is a thermoplastic acrylic resin polymer and the core is a spherical plastic particle composed of alkane gases. The diameter is generally 10-45 microns. After heating, the volume can rapidly expand to tens of times than its own, thus achieving the effect of foaming. The foaming temperature ranges from 75 -260 C. microspheres are small spherical thermoplastic particles. When heated, the internal pressure from the gas increase and the thermoplastic shell softens, resulting in a dramatic increase of the volume of the microspheres. The gas remains inside the spheres.

[ Application ]

Widely used in slippers, soles, insoles, plastic wallpaper, artificial leather and other field.
