PIR【1】 and PUR【2】 are both derived from polyurethane，Just 13 years later in 1967, scientists improved upon PUR’s thermal stability and flame resistance to create polyisocyanurate (PIR). So what’s the difference between the two? PIR is well known for usage as a low-moisture barrier, similar to PUR. Its distinctiveness is what sets PIR apart the most. When compared to PUR materials, PIR slows the spread of the flames and lowers the amount of smoke that the fire emits.
Although the two are different in terms of performance, in general, both belong to foam, and both can be recycled using a foam recycling machine, which belongs to the common denominator of the two. The foam recycling machine used in the recycling of PIR foam and PUR foam is different.
Foam recycling machine for PIR
The recycling of PIR foam has only been in demand in recent years. As a foam recycling expert, there are customers who put forward a demand. GREENMAX helped customers solve the problem at the first time, and began to test what kind of foam recycling machine can recycle PIR foam well. Finally, We have found that PIR foam can be efficiently recycled using the Foam Hydraulic Compactor, which is an essential step in recycling foam by first compressing it into dense foam blocs using the Foam Hydraulic Compactor.
Foam recycling machine for PUR
At present, there is no good method for the recycling of this foam in the entire mechanical recycling market. If you want to achieve the purpose of volume reduction, GREENMAXA recommends using a foam crusher. This machine has a powerful crushing function and can be crushed according to the density of the material. The device can achieve the effect of fully crushing the material, and it is very easy to crush the PUR foam. Foam crusher is a very popular small foam recycling machine in recent years. Although it only has a crushing function, it can achieve the purpose of volume reduction. (Although not as high compression ratio as other large foam recycling machines), but it is a good choice when dealing with some special materials. Recently, more and more customers have been inquiring about the GREENMAX foam crusher, which is very suitable for customers with limited budget and space.
GREENMAX has already realized the recycling of PIR foam and PUR foam. If you have any needs in this regard, please feel free to contact us, or if you are interested in other GREENMAX foam recycling machines, don’t hesitate, we will answer your questions at any time.
