 Our
HIPS sheet uses the HIPS (high impact polystyrene)
resin which has good plasticity and stable
physical properties. It is suitable for food
containers or trays as it is light. It also
has no odor, taste and does not give any harm
to the human body. Moreover, it has very good
insulation properties.
Our conductive PS sheet and its vacuum forming
products have a good surface resistance property
of 104 ~ 106Ω/sq so
that it is very good for use as a tray for
electronic parts, such as semiconductors,
which are very sensitive to electric reaction.
Besides, we manufacture products that have
fire resistance PS products, meeting the every
need of our customers.
