Extrusion

Celanese Corporation and Under Armour, Inc. have joined forces to introduce NEOLAST™, a groundbreaking fiber for performance stretch fabrics. NEOLAST™ provides elite-level performance attributes—stretch, durability, and comfort—while addressing sustainability challenges linked to traditional elastane (spandex) fibers.

Advanced machinery that can effectively decontaminate post-consumer plastics is the key to producing rPET with exceptionally high purity. This quality is essential for FDA-approved food-grade packaging.

A pair of U.S. defense-related organizations –– America Makes and NCDMM –– have awarded funds to a project designed to optimize recycled PET (rPET) and rPET-based composites in filament-fed material extrusion 3D printing.

The diagnosis and monitoring of extrusion processes have historically relied on rule-based algorithms. While effective for many years, this conventional approach faces inherent limitations. These limitations include a restricted number of controllable parameters, vulnerability to irrelevant outliers, and heightened complexity in systems with extensive degrees of freedom.

Specialized equipment that enhances skin recovery in chronic wounds usually needs biocompatible, sterilizable, and durable materials. For this reason, Vaporox developed the VHT-200 to foster revascularization and tissue growth in chronic skin wounds using a high-tech polycarbonate. Tailored for clinic and physician office use, the medical device required a robust material for its vaporizer component. Due to the device’s significance, technical support from the plastic supplier was a crucial factor in the decision-making process.

Experts recognize reusability models in packaging as a solution to minimize waste. McKinsey & Company’s use-case scenarios indicate that there are still challenges to resolve before realizing and scaling up the benefits.

Most companies would like to improve their sustainability but they do not know where to start and do not have a method of assessing their current status. Without knowing where you are starting from it is impossible to plot a route to where you want to get to. 

The additive aids biodegradability by changing the polymer structure, converting it into a wax-like material after being exposed to light, water, moisture, and microbes.

Polymeric materials are the backbone of various industries, ranging from packaging and electronics to automotive and aerospace. The melt flow behavior of thermoplastic polymers, crucial for processes like extrusion, injection molding, and more, is significantly influenced by their molecular architecture. Plastics engineers aiming to tailor polymeric materials to specific physical properties and ensure top-notch manufacturing processes need to master the art of rheology.

In the realm of plastics engineering, additive manufacturing stands as a game-changer, slashing lead times and enabling the creation of intricate, custom parts through techniques like fused filament fabrication (FFF). While hailed for its prowess, challenges persist in achieving consistent isotropic bulk properties and ensuring reliability in the printed components.

The Society of Plastics Engineers (SPE) invites you to join their team of instructors as they develop educational programs and workshops for their audience of plastics professionals seeking to enhance their work skills and abilities. Instructors will lead workshops that break the mold, offering unique perspectives and insights that resonate with their audience.

The plastics industry mainly uses PFAS as polymerization aids and this would be the main cause of PFAS emissions related to the life cycle of fluoropolymers.
