Since many plastic products are made of a combination of materials with very different melting points, careful consideration must be given to designing screws when it comes time to recycle these products.
When utilized in a thoughtful way, the corotating intermeshing twin-screw extruder can transform recycled materials into value-added products and parts. Here’s what you need to know, and some real-world examples of the technology deployed for both post-industrial and post-consumer recycling.
Three distinguished experts in the area of reactive extrusion shed some light on this process.
SABIC Steps-Up Specialty Thermoplastic Resins Fulfillment to Expedite Production of Critical COVID-19 EquipmentBy: Lilli Manolis Sherman
Two Chinese manufacturers swiftly received SABIC’s specialty engineered resins for the manufacture of much needed medical equipment.
Gloss, reflection haze, and transmission haze are three of the most prevalent effects on the appearance of plastics. With the help of multifunctional tools like gloss meters and spectrophotometers manufacturers can measure these visual affects to ensure the integrity of a products appearance from start to end.
Presented with IMTS spark, the series will explore how 3D printing technology is changing the face of manufacturing.
As with semi-crystalline thermoplastics, annealing can be used in thermosetting polymers to obtain a level of crosslinking that may not be possible within the molding cycle.
“Better” is the wrong metric—instead, molders should understand the key differences between tooling and appreciate where in the product lifecycle each technology fits best.
Danimer Scientific and WinCup, who developed first-of-its-kind backyard compostable and marine biodegradable straw, honored by PLASTICS.
Besides speed and quality advantages, the low-pressure iMFLUX process is said to enhance sustainability—easing use of recycled and biobased materials, saving energy, reducing scrap, and adding lightweighting potential. See what molders say about these “green” benefits.
