Core Features

Bead shaped raw material containing foaming agent (pentane). During processing, it expands due to heat, resulting in lightweight products with excellent insulation and cushioning properties. According to different particle sizes and foaming ratios, it is divided into ordinary type, flame retardant type, light/medium/heavy grade and other specifications.

Mainstream solution

Suspension polymerization produces beads containing foaming agents, with a particle size range of 0.3~1.6 mm and a one-time expansion ratio ranging from 35 times to 90 times. Flame retardant type with added halogen-free flame retardants (such as HBCD Free).

Key data

-Foaming agent content (pentane): 4.4%~5.8% wt
-Particle size range: 0.3~1.6 mm (depending on the brand)
-One shot magnification: 35-90 times
-The density of the molded product can be as low as 10-14 kg/m ³

Typical Applications

Building insulation board, cold storage insulation, mechanical and electrical product buffer packaging, food packaging (fresh box, foam box), agricultural and fishery packaging, floating ball, handicrafts, lost foam.
