Weihai Hanwell New Material Co.,LTD was established in 2020, as a
member of Han Well Group with Qingdao Hanwell Hightech Plastic
Co.,Ltd. With the 20 years development, now the factories cover an
area of 100,000 square meters and the workshop is about 80,000
square meters, 50 production lines, the total investment is more
than US dollars 50,000,000.
From the EPP raw material, EPP forming products, molded pulp
products, therm forming products, plastic slip sheet, we have
realized the industrial chain highly vertically integrated in every
these industries. Meantime we have a lot of advanced machines from
Germany, that improve the quality, reduce the cost, so we can
provide competitive price and ensure the big order delivery on
time.
With experience on working with the world-class customers from all
over the world in the past years, our teams deal with a lot of
important cases, our engineer team can help design per customers’
request. Besides this, our aim is to provide the comprehensive
solution and help to achieve the constant development together.
As a responsible manufacturer, we work hard on developing new
biodegradable and reused packaging, we always improve technology
and reduce the energy consumption to achieve the goal of the carbon
neutrality and protect our world. If you have packaging request,
welcome to contact us, we will be very glad to help you.
EPP is a polypropylene foam consisting of expanded, mainly
closed-cell foam particles. The EPP beads are filled with air and
therefore particularly environmentally friendly(light weight). They
guarantee a good joint tightness of the moulded parts and provide
an excellent insulation and thermal insulation.
A high energy absorption（shock resistance）capacity combined with a
very good recovery behaviour are characteristic properties of EPP
in addition to the good chemical and temperature resistance. The
low water absorption( water proof) due to the closed-cell structure
and hydrophobic surface property, the easy cleaning of moulded
parts, the good thermal insulation capacity as well as its
environmental compatibility (= free of propellants and other
chemical blowing agents) round off the property profile of EPP.
For the use as reusable packaging and reusable transport and
insulation containers, the excellent material properties of EPP are
used in an ideal form.
Processing
EPP is processed on automatic foaming machines which are designed
for a steam chamber pressure of at least 5 bar. The foam particles
are transported from a pressurized container via injectors into the
mould. Since EPP does not contain any blowing agent, it is
necessary to compress the foam particles in the mould. Welding of
the EPP beads to a molded part is done by using water vapor as heat
transfer medium. The demoulding is done by mechanical ejectors
and/or compressed air. For dimensional stabilization, the molded
parts must be tempered (= dried) at approx. 80°C after demolding.
Application areas
The specific product properties of EPP are innovative and
unrivalled and make EPP a multifunctional material with almost
unlimited design possibilities for a wide range of applications.
EPP proves itself in areas where strength at low weight, high
stiffness or good thermal properties are required, such as
- Automobiles as energy-absorbing foam such as bumpers, side impact
protection or for sun visors or neck supports
- As protective and reusable packaging for sensitive products
- Electronic engineering as well as heating, air conditioning and
sanitary engineering as a multifunctional part with multiple uses
(impact protection, thermal insulation)
- In safety relevant products such as child seats and bicycle helmets
- The toy industry or the design and furniture sector
- For the transport of temperature-sensitive foodstuffs from A to B
