Process of polypropylene foam (EPP) moulding
====================================================
EPP Manufacturing Theory
------------------------
"Generally, in order to manufacture plastic (polymeric) foam, the
polymeric material should have suitable melt viscosity for the growth
and stabilization of foam cells (bubbles) in a suitable foaming
condition. The polymeric material can be divided into crystalline
polymers and amorphous polymers in large. In the case of PS
(Polystyrene), an amorphous polymer, the viscosity decreases slowly as
temperature increases so the foam manufacturing temperature range is
wide and stable. However, in the case of PP, a crystalline polymer,
the melt viscosity drops quickly around melt temperature Tm, so the
temperature range suitable for foam is very limited. Therefore, in the
case of PP, precise foaming conditions (temperature/pressure) should
be maintained to manufacture high foam bead products. In addition, due
to the fast gas permeability of PP resin, the foaming agent (butane)
inside of a cell evaporates quickly after bead manufacture. Therefore,
unlike EPS produced as a pre-foam bead with impregnated foaming agent,
EPP is produced in foam in the bead manufacturing plant.
In the mold process, the high melt temperature and fast gas
permeability of PP eliminate the use of the EPP molding process and
facilities and requires molding facilities that are exclusive for EPP
use. The high melt temperature of PP resin used for EPP manufacturing
also requires high molding pressure. Due to the fast evaporation of
the foaming agent in particular, only air exists from the foam when it
is supplied to molding companies. Therefore, a foaming agent (air)
injection process is necessary to provide molding foaming capacity
before this molding process can be done.
EPP Production process
----------------------
The EPP process is composed of the raw material foam bead
manufacturing process and a molding process. The raw material foam
bead manufacturing process employs a totally different process from
the existing EPS manufacturing process. First of all, PP resin is cut
to mini size, considering the ultimately desired size of the foam.
Then, impregnating and foaming are carried out consecutively in an
autoclave to produce bead type foam material. The target foam ratio is
obtained by controlling the foam°Øs temperature and pressure."

APPLICATIONS
====================================================
"Applications for EPP continue to grow dramatically. JSP International
has been at the forefront in developing the use of EPP in industrial
and consumer products. Primary among these is automobiles, where
lightweight, cost effective bumper components made from ARPRO® EPP
absorb energy in low-speed collisions to help minimize damage."
http://www.jspi.com/applications/index.html
AUTOMOTIVE
----------
"When JSP International introduced automobile manufacturers to EPP and
demonstrated how it delivers lightweight, cost effective energy
absorption for bumper applications, many of them looked to JSP
International to help engineer and develop the key components."
(..)
* Laminated shape molded EPP door panel
* Tool kit
* B pillar
* Sun visor
* Instrument panel Carpet underlayer / Floor leveler
* Side impact protection (Porous EPP)
* Energy absorbing bumper components
http://www.jspi.com/applications/automotive.html
"Kautex-Textron have developed, with the support of JSP International,
a new family of applications for EPP with an innovative new process
combining conventional blow molded parts filled partially or
completely with EPP foams.
The development has concentrated on three types of automotive
applications. A blowfilled under-floor leveler, where the new
technology provides a very cost effective, CW value optimized, weight
optimized, and acoustic function part, in an easy to recycle one
material concept. Another application area concentrates on parts for
acoustic dampening of engine noise.
Blow moulded and particle foam filled bumpers is the third challenging
area for applications. A "Class A" surface can be combined with energy
absorbing capabilities. The result is a highly competitive,
multifunctional bumper for which conventional solutions need various
separately moulded parts."
http://www.jspi.com/applications/auto_10_05_01.html
"Lighter, saver, more comfortable, energy saving and environmentally
friendly - these factors determine future development within the
automotive industry. Taracell foam materials satisfy these criteria,
not only for demanding technical solutions but also for economy and
ecology. Our foam materials offer an excellent perspective.

* Logistic and transport support PPE
* Headpadding with skinmolding
* Impact protection PPE

CONSTRUCTION
------------
"The properties of Neopolen® P [EPP] make it a versatile engineering
material which can carry out more than one task at the same time. It
can function at the same time as packaging, housing, impact
protection, heat insulation and sound insulation."
http://www.basf.de/basf/html/plastics/englisch/pages/schaum/neopolen.htm
PACKAGING
---------
"ARPRO® EPP is the material of choice for packaging applications where
lightweight, multiple impact protection, and reusability are essential
performance criteria. Consumer products such as computers and
sensitive electronic equipment are protected from rough handling
throughout the distribution process."
http://www.jspi.com/applications/packaging.html
RECREATIONAL PRODUCTS
---------------------
"ARPRO® EPP helps enhance the performance of water sports vehicles,
including pleasure craft and jet skis, as well as sport boards used in
salt water and on snow."
http://www.jspi.com/applications/packaging.html
Gliders / Sailplanes / RC aircraft

ACOUSTIC
--------
"ARPRO® Porous EPP represents what may be a new class of acoustic
materials. Most commonly used acoustic insulation materials require
structural support."
http://www.jspi.com/applications/acoustic.html
SPORTS SURFACES
---------------
"For sports surfaces, this creates the possibility of a cushioning
layer for heavily used sports surfaces, such as tennis courts,
soccer/football fields, and similar applications. Additional uses
include hydroponic growing, where porosity, structural stability, and
resistance to exposure to fertilizers and other chemicals used in
growing is imperative."
