Application Research of Foamed Polypropylene
PP foaming materials have a wide range of applications in food
container packaging, thermal insulation, automotive and
The chemical structure of PP makes the PP foam material have good
degradability and recyclability, and good oil resistance, which makes
it have obvious advantages in the disposable packaging market over
the difficult-to-degrade PS foam meal.
PP foam material is a new type of thermal insulation material with
strong temperature resistance. It can usually withstand a temperature
range of -40 ° C ~ 110 ° C and a high temperature of 130 ° C in a
short time, which is higher than PE foam. The maximum operating
temperature (80 ° C), shows good performance even at -30 ° C.
Due to the void structure of foamed PP, its thermal conductivity is
greatly reduced. At present, it has been widely used in situations
where the heat resistance of other foamed materials does not meet
the requirements, such as for heat insulation of heat carrier cycle
batteries exceeding 100 ° C. Materials, air conditioners, refrigerators,
insulation in motor rooms and ironmaking workshops, cushioning
packaging materials, and more.
The use of PP for the plastics used in automobiles can reduce the
weight of automobiles, thereby saving energy and reducing
emissions, and is of great significance for the recycling and reuse
of automotive materials.
Foamed PP material has good mechanical properties, its rigidity is
better than PE, PP, PP has similar chemical resistance to PE, and can
be widely used as a building material in the construction industry.
