Specialty chemicals company LANXESS is offering the next generation of Low Free (LF) isocyanate urethane prepolymers that can be formulated into resins for 3D printing (additive manufacturing).
In order to create such resins LANXESS works together with 3D printing companies. Based on Adiprene LF pPDI (para-phenylene diisocyanate) prepolymers, these high performance resins are easy to process and safe for industrial manufacturers as well as for the casual home, office or retail user.
High performance resins for the footwear industry
The footwear industry is a key user of 3D printing technology for midsole, upper, and structural components such as heels and toes. Footwear components are designed to require both very soft and more rigid elastomers. The wide flexibility to formulate LF prepolymers into printable resins enables 3D printers to drive toward mass customisation, enabling printing across a wide range of hardness from very soft elastomers for cushioning to the more structural shoe elements.
Superior user safety
Companies are looking for the safest materials for their customers who are not familiar with handling chemicals, especially in uncontrolled home, office, and retail environments. LF technology enables 3D desktop printing where low hazard classifications are critical. Adiprene LF pPDI prepolymers contain less than 0.1% residual isocyanate, reducing the hazard classifications and protecting users from potential exposure.
