Achieve domestic substitution! 20,000 tons/year EPP degradable materials project is proposed

Recently, the high-performance expanded polypropylene (EPP) degradable material project of Qingdao Zhongke Ruibang New Material Technology Co.
, Ltd.
has industrial production capacity, and plans to build a production base
with an annual output of 20,000 tons.

Relying on the technology of the Chinese Academy of Sciences, Qingdao Zhongke Ruibang New Material Technology Co.
, Ltd.
has developed a new EPP production process originally, realized the localization of raw materials and equipment, and the product performance indicators are better than domestic leading enterprises, and some even surpass overseas giants such as JSP in Japan, and the cost is lower
.

What is EPP

EPP, short for expanded polypropylene, is a high-performance "green" foamed resin
.

There are many types of polymer foam materials on the market, and the most widely used are polystyrene (PS), polyurethane (PU) and polyethylene (PE) foams
.
However, these plastic foams have problems such as
difficult recycling, harmful to the human body with material residues, and poor heat resistance or mechanical properties.

Polypropylene foam material (EPP), has excellent heat resistance and mechanical strength, and is much better than other foam materials in terms of environmental friendliness, but due to its preparation of raw materials PP high crystallization, low melt strength characteristics, foaming preparation process is more difficult, so in China has not yet achieved large-scale industrial production, about 80% of the domestic EPP market is still occupied by foreign enterprises
.
At the same time, in view of the high dependence of domestic PP raw materials on imports and backward supporting preparation equipment and technology, there are problems such as
single, few functionalization differences, unstable quality and high cost of domestic EPP products.

Application of EPP

As a high-performance, degradable "green" foaming resin, polypropylene foam bead EPP has excellent shock and energy absorption, heat resistance, oil resistance and heat insulation
.
Widely used in military, automobile, construction, children's toys, food packaging, household appliances and other fields: car bumper, seat, trunk; large LEGO bricks for children; Logistics packaging boxes, home appliance packaging boxes; Thermal insulation cotton, sofas, mattresses, etc.
can be replaced
with EPP.

20,000 tons/year EPP project

In the "Made in China 2025" issued by the State Council, one of the key directions for the development of polymer materials in the overall plan of the new material industry is the production technology and application
of expanded polypropylene.

At present, Qingdao Zhongke Ruibang New Materials has completed the construction of an industrialization demonstration line with an annual output of 1,500 tons, and has begun to cooperate
with downstream automotive fields, packaging fields, and floating body application enterprises.

Through 1-2 years, Qingdao Zhongke Ruibang New Materials hopes to complete the relocation and transformation of the mass production line, stabilize the batch supply market, take EPP general materials as the starting point, and strive to achieve a saturated production capacity of 5000-8000 tons / year
.

In the third and fourth years, the new plant will be planned and constructed
.
Purchased expanded equipment, increased 16 polypropylene foaming production lines, reached a stable annual output of 20,000 tons, and gradually built the company into the top three in China and the top five in the world EPP material production enterprises
.
