Today, the Expanded polypropylene (EPP) foam market will grow steadily. According to relevant reports, the growth rate will exceed 4.2% by 2031. This is inseparable from the extensive use of EPP in the automobile industry. As we all know, expanded polystyrene (EPS) is very well-known, but it is not popular in the automobile industry. This is because EPP is superior to EPS in high heat resistance and high impact energy absorption, which makes EPP often used in automobile parts, such as decorative materials and bumpers.

 

As the old saying goes, every coin has two sides. Although EPP packaging is superior to EPS in the application of auto parts, it is difficult to recycle because its hardness is higher than EPS. And its wide application means a huge amount of waste meanwhile. Nowadays, EPP recycling has been paid more and more attention to the development of environmental protection. EPP densifier is an excellent method.
 


As a material of auto parts, one of the most difficult reasons to deal with EPP is its high hardness, but the crushing knife equipped with an EPP densifier can perfectly solve this problem. As long as the waste EPP waste is put into the hopper, the crusher will start to operate and cut the EPP into many small pieces. Some people may worry that EPP densifier can't cut EPP very small, but it's not a trouble for recycling companies like GREENMAX. The two-stage crushing knife designed by GREENMAX can completely crush EPP. Then the hot-melting system of the EPP densifier will compact the EPP waste into densified ingots.
 


The biggest advantage of EPP densifier in recycling EPP is that it can use the hot melting machine as a bridge between waste EPP and plastic particles so that EPP recycling can be realized 100%. With the further popularization of home appliances and the popularity of EPP, EPP recycling should be paid more attention to.
