Today, I would like to introduce you to a "Hundred Variable Star King" material
In life, we can actually see ta often
TA is foamed polypropylene (EPP)
What are the applications of EPP?
What are the main manufacturers?
Let's take a look
Polypropylene plastic foam material (EPP) used in industry is composed of two phases of solid and gas, black, pink or white granular, and the diameter size is generally between φ2 and 7mm. The outer wall of the EPP particles is closed and filled with gas inside. Usually, its solid phase composition accounts for only 2% to 10% of the total weight, and the rest is gas.
In recent years, the application of EPP has "exploded" and grown
It can be said that where you need TA, there is TA figure ~ ~
EPP's "Changeable Show"
EPP has good heat resistance, good dimensional stability, cushioning performance, low temperature characteristics, oil resistance, chemical resistance, and 100% degradable, recyclable and many other advantages. This "little round bean" has penetrated into all aspects of our lives.
<h1 class="pgc-h-decimal" data-index="01" data-track="29" > automotive field</h1>
With the development of automobile lightweighting, material lightweighting plays a pivotal role in automobile weight reduction. EPP is a closed bubble structure, which can fully absorb fugitive energy to buffer and resist earthquakes; extremely high stability, rapid recovery when deformation; heat insulation and moisture-proof, noise reduction; extremely light in quality and environmentally friendly materials, therefore, the application of EPP in automobiles has increased year by year.
Foamed polypropylene materials are used for example. According to statistics: the average amount of plastic used in cars is currently 100 to 130 kg / car, of which 4 ~ 6 kg / car is used in foam polypropylene.

01. Fresh cold chain
As early as 2016, SF recycled the EPP-made incubator as a cold chain.
EPP circulation incubator has the characteristics of heat preservation, heat resistance, corrosion resistance, insulation, etc., is a kind of environmentally friendly cold chain packaging that can be digested after heating, suitable for fruit, frozen meat, ice cream and other food transportation, instead of traditional cold transport foam box, partition, etc.
SF also designed a pink EPP cold chain box for cherry transportation▼
According to the data, in 2016, SF Cold Transport EPP circulating incubators were invested in a total of 120,000 batches, with a cumulative number of uses of 1.57 million times. If these quantities are converted according to the equivalent size, it is equivalent to saving 1.57 million foam boxes + 1.57 million cartons + 3.14 million ice packs! This means that about 20.45 million yuan in packaging material costs and 720,000 kilograms of carbon emissions are saved, which is equivalent to cutting down 9,100 trees. It is worth noting that each EPP incubator can be reused more than 250 times.
There are also many world-renowned catering companies that also choose EPP as their own insulated food delivery boxes.
02. Buffer packaging
In addition, as a buffer packaging, EPP can also protect products that are easy to be "injured" such as fruits, refrigerators, and ceramic products during transportation.

03. Electronics
The lightweight, antistatic, conductive and anti-voltage cushioning properties of EPP parts can minimize electrostatic damage and collision damage during transfer or transportation of electronic products.

EPP is a non-toxic, harmless and recyclable environmentally friendly material that avoids poisoning caused by children nibbling on toys. Its products have moderate hardness, good flexibility, no need to worry about bumps or scratches, give children gentle protection, anti-slip insulation and changeable play experience, is an emerging children's toy material. EPP has better seismic energy absorption performance and is more often used to make child safety seats.
At the same time, EPP is also the preferred material for more and more household goods manufacturers advocating environmentally friendly life.

As a mattress material, EPP has many advantages such as light weight, safety and non-toxicity, good flexibility and support, can make complex heterosexual structures, can be washed, and is not easy to breed bacteria.
EPP is applied in the middle layer of the helmet to play a cushioning and shockproof role.
