Applicability
PKF-XJ is the raw material of high expansion ratio for the production of low-density beads by one-time expansion and is even suitable for marking lighter plastic foam by several expansion steps. It is therefore most suited to applications requiring densities of less than 18g/l by one time expansion and 10g/l by several expansions. Applications include machinery and electronic product packaging, fishing flotation buoys, crafts, well as light board.

Outstanding Properties of PKF-XJ
●Fast expanding and high expansion ratio in unit time. Energy -save and efficient.
●Low density after expansion (10.5-15g/l), suitable for low-density products.
●Even lower density after several expansions,satisfying the requirement by low-density block products.
Recommended Processing Conditions
●The processing of EPS consists of pre-expansion, maturing stage, block molding and shape molding.
●If several expansions are needed, the first expansion should be specially noticed controlling the interval between expansions within 3-6 hours (short in summer while long in winter ) in order to avoid the expanded beads being over-shrinked. The time in marturing stage directly influence the highest ratio and hardness of block.
●The low-density block should be removed the inner water in heating room in order to improve the output ratio of block and to make the cut block surface smooth.
