In injection moulding and extrusion processes, using 𝐫𝐏𝐄𝐓 produced with 𝗛𝘆𝗽𝗲𝗿𝗣𝗘𝗧 means achieving an 𝗶𝗺𝗺𝗲𝗱𝗶𝗮𝘁𝗲 𝗲𝗻𝗲𝗿𝗴𝘆 𝘀𝗮𝘃𝗶𝗻𝗴, because the energy required to melt the pellets is significantly lower compared to materials obtained with the technologies currently on the market.
The reason lies in the crystallinity: 𝗛𝘆𝗽𝗲𝗿𝗣𝗘𝗧 delivers a final value between 𝟯𝟳% 𝗮𝗻𝗱 𝟰𝟬%, whereas competing systems exceed 𝟱𝟬%.
Why this difference?
Because, unlike other solutions, 𝗛𝘆𝗽𝗲𝗿𝗣𝗘𝗧 𝗽𝗲𝗿𝗳𝗼𝗿𝗺𝘀 𝗦𝗼𝗹𝗶𝗱 𝗦𝘁𝗮𝘁𝗲 𝗣𝗼𝗹𝘆𝗰𝗼𝗻𝗱𝗲𝗻𝘀𝗮𝘁𝗶𝗼𝗻 (𝗦𝗦𝗣) 𝗯𝗲𝗳𝗼𝗿𝗲 𝗲𝘅𝘁𝗿𝘂𝘀𝗶𝗼𝗻.
As a result, the produced pellet is 𝗻𝗼 𝗹𝗼𝗻𝗴𝗲𝗿 𝗲𝘅𝗽𝗼𝘀𝗲𝗱 𝘁𝗼 𝗵𝗶𝗴𝗵 𝘁𝗲𝗺𝗽𝗲𝗿𝗮𝘁𝘂𝗿𝗲𝘀 𝗮𝗳𝘁𝗲𝗿 𝗽𝗲𝗹𝗹𝗲𝘁𝗶𝘇𝗶𝗻𝗴, meaning it does not undergo what is often referred to as “secondary crystallization”.
The outcome is a lower crystallinity - yet 𝗽𝗲𝗿𝗳𝗲𝗰𝘁𝗹𝘆 𝗶𝗱𝗲𝗮𝗹 𝗳𝗼𝗿 𝗶𝗻𝗷𝗲𝗰𝘁𝗶𝗼𝗻 𝗺𝗼𝘂𝗹𝗱𝗶𝗻𝗴 𝗮𝗻𝗱 𝗲𝘅𝘁𝗿𝘂𝘀𝗶𝗼𝗻 𝗽𝗿𝗼𝗰𝗲𝘀𝘀𝗲𝘀.
It's important to note that PET in the melt state is always amorphous: solid-state crystallinity is necessary for processing, but once it exceeds a certain threshold, it becomes an obstacle to melting, increasing energy consumption in terms of joules per gram.
In other words, a material with 𝗲𝘅𝗰𝗲𝘀𝘀𝗶𝘃𝗲 𝗰𝗿𝘆𝘀𝘁𝗮𝗹𝗹𝗶𝗻𝗶𝘁𝘆 requires 𝗺𝗼𝗿𝗲 𝗲𝗻𝗲𝗿𝗴𝘆 to be processed.
With 𝗛𝘆𝗽𝗲𝗿𝗣𝗘𝗧, recyclers can instead offer their customers a 𝗳𝗼𝗼𝗱-𝗴𝗿𝗮𝗱𝗲 𝗿𝗣𝗘𝗧 that combines recycled origin with reduced energy consumption during transformation.
A dual environmental benefit:
✅ Use of recycled material;
✅ Optimization of the energy required for injection moulding and extrusion.
For rPET producers, 𝗛𝘆𝗽𝗲𝗿𝗣𝗘𝗧 represents a 𝘂𝗻𝗶𝗾𝘂𝗲 𝗰𝗼𝗺𝗽𝗲𝘁𝗶𝘁𝗶𝘃𝗲 𝗮𝗱𝘃𝗮𝗻𝘁𝗮𝗴𝗲: providing a material that is not only recycled, but also 𝘀𝗮𝘃𝗲𝘀 𝗲𝗻𝗲𝗿𝗴𝘆 for the end user.
