The simple replacement of petroleum-based components with renewable alternatives in a well-established reactive extrusion process is a promising route to more environmentally friendly thermoplastic polyurethane elastomers (TPU). However, this requires a comprehensive understanding of the interactions between chemical reactions and material flow within an extruder, as well as a thorough understanding of the effects of heat and shear on polymerization and melt processing.

Walking on Bioplastics

Increasing demands on component functionality and the need for efficient manufacturing processes are keeping multi-component injection molding squarely in the focus of plastics processing. Not all materials can be processed reliably in the desired combination. The new InMould-Plasma process, which is fully integrated into the injection molding process, facilitates more-efficient production and paves the way for completely new material combinations.

TPE Compounds with Recycled Content

Kraiburg TPE’s latest thermoplastic elastomer (TPE) has been specially developed for consumer and industry applications and contains up to 40 % post-consumer recyclate (PCR). In accordance with standard ISO 14021, the manufacturer recycles materials that end consumers from households and the industry can no longer use for their intended purpose.

The latest solution from Kraiburg TPE makes a post-consumer recycling proportion of 40 % possible. The TPE is partly made from household waste.

Lightweight Thermoplastic Composite Bearing

Trelleborg Sealing Solutions launches its latest lightweight thermoplastic composite bearing.

Trelleborg Sealing Solutions launches its latest lightweight thermoplastic composite bearing, the HiMod Advanced Composite Bearing Plus, an enhanced dual-layer bearing with a low-friction modified PEEK layer that reduces friction and increases wear performance for use in bearing, wear ring, and bushing applications.

Manufactured using Trelleborg’s patented Automated Fiber Placement (AFP) technology, a thin low friction liner is bonded to the inner diameters and can be added to the outer diameters of the bearing. According to the company, the new bearing will not seize or gall, unlike metal bearings, to reduce the likelihood of pump damage in chemical processing applications, has a low coefficient of friction, and can withstand extreme temperature ranges.

Reid Hislop, Product Manager at Trelleborg Sealing Solutions, says: “Thermoplastic bearings offer high durability and toughness for demanding applications. The addition of a low-friction layer within our HiMod Advanced Composite Bearing Plus provides up to 50 % less sliding friction than with standard bearings, to increase performance and prevent damage to hardware components.

The New Bearing Do Not Crack or Swell in Extreme Conditions

“These unique bearings can operate from an extremely low temperature of –156 OC to +274 OC / –250 OF to +525 OF and are capable of continuous service even when wet, with nearly zero water absorption. Unlike other non-metal bearings, these do not crack or swell in extreme conditions making them a reliable choice for a wide range of applications.”

Trelleborg’s AFP technology is part of a special continuous-fiber thermoplastic composite manufacturing process, which uses pre-impregnated unidirectional composite tapes to produce strong, light-weight composite bearings and other components. The manufacturing process utilizes In-Situ Consolidated (ISC) technology that requires no autoclave or other post processes to eliminate fiber wrinkling and offer an unlimited choice of fiber angles. Components are rapidly formed by a melt-bond process, which removes the need for adhesives, fasteners, or welding. ISC technology enables the bonding of different materials which can result in the creation of new, hybrid structures.

Hislop, continues: “Our low-friction PEEK liner doubles as a highly impermeable sealing surface to provide wide chemical compatibility including solvents and environmental contaminants, and unlike traditional thermoset composites, thermoplastic composites can be recycled at the end-of-life.”
