Soft lithographic techniques were used to fabricate polymeric microparticles for drug delivery applications. The microparticles were made of thermoplastics and thermosets from different types of precursors including reactive resin and polymer solutions in organic solvents or water. The microparticles produced using these methods were made of widely used polymers for drug delivery with highly un...

Vorbeck Materials, Inc., Jessup, Md. (301) 497-9000 Nano-fillers for enhancing thermoplastics and thermosets continue to make headway in commercial applications, although at a slower pace than had been anticipated. A rethinking of how best to utilize them is resulting in easier-to-process second-generation products with improved surface modification, as well as some brand-new entrants in this e...

Polyetheretherketone (PEEK) has been the focus of substantial additive manufacturing research for two principal reasons: (a) mechanical performance approaches that aluminum at relatively high temperatures thermoplastics and (b) potential qualification in both aerospace biomedical industries. Although PEEK provides outstanding strength thermal stability, printing can be difficult due to melting ...

An experimental investigation was carried out to study the effect of thermoplastics’ addition reinforcement corrosion and durability concrete. A long-term is necessary for final decision on possibility utilization materials, this contributing direction. Two types thermoplastics were used, high-density polyethylene polypropylene. The percentage replacement conventional aggregates 0% 12% by volum...

Thermoplastic rubbers are materials that combine the characteristics of good processability of thermoplastics with the physical properties of vulcanized rubber. SEBS is a SBS which has been subjected to a hydrogenation process, through the polybutadiene chain is eliminated. This new rubber has a high resistance to environment, temperature, UV radiation, etc. without losing the properties of a t...

This paper reviews effects of amplitude and force control during the ultrasonic welding cycle of thermoplastics. In a previously published paper, the benefits of amplitude profiling were detailed as increased strength and reduced part marking. This paper reviews the mechanisms for such observations and details additional benefits, such as decreased residual stresses and increased solvent resist...

In this study, we propose one-step chemical modification of plastics for bonding various plastics with poly(dimethylsiloxane) (PDMS) elastomer at room temperature. This was realized by anchoring poly[dimethylsiloxane-co-(3-aminopropyl)methylsiloxane] (amine-PDMS linker), a chemical composed of a PDMS backbone incorporating an amine side group, on the surface of thermoplastics. Following corona ...

AkzoNobel’s range of organic peroxides for the crosslinking of elastomers and thermoplastics is the world’s largest, including a number of organic peroxides for the production of PEX-a pipes and tubes. Our products are marketed under the well-known trademark of Trigonox. When producing PE pipes and tubes, frequently high density polyethylene (HDPE) is used. To further improve the product proper...

Abstract. In the thermoforming process shearing of fiber reinforced thermoplastics (FRTP) leads to wrinkle formation and is therefore one most critical deformation mechanism. The target value predict shear angle which considered in this paper. To distribution during FRTPs a Convolutional Neural Network (CNN) used. approach based on consideration principal curvature characteristics, resulting re...
