Halloysite nanotubes-thermoplastic polyurethane (HNTs-TPU) nanocomposites are attractive products due to increasing demands for specialized materials. This study attempts to optimize the parameters for injection just before marketing. The study shows the importance of the preparation of the samples and how well these parameters play their roles in the injection. The control parameters for injec...

Flax fibres are oftenly used for reinforcing thermoplastic to manufacture biocomposite materials exhibiting numerous advantages such as high mechanical properties, low density and biodegradability. The mechanical properties of a biocomposite material depends on the nature and orientation of the fibres, the nature of the matrix and mainly on the adhesion between fiber and the polymer matrix. The...

A unique technique for the rapid fabrication of thermoplastic microfluidic chips is described. The method enables the realization of fully-sealed microchannels in around one hour while requiring only minimal infrastructure by taking advantage of a solvent swelling mechanism that allows raised features to be patterned on the surface of homogeneous thermoplastic materials. Patterning is achieved ...

Thermoplastic vulcanizates (TPVs) are a special class of thermoplastic elastomers, which are produced by simultaneously mixing and crosslinking a rubber with a thermoplastic polymer at an elevated temperature. Peroxide-cured TPVs based on blends of silicone rubber and thermoplastic Engage of two different types, mainly ethylene-octene and ethylenebutene copolymers at different blend ratios have...

We report a cost-efficient and easy to implement process for fabricating microfluidic reactors in thermoplastic materials. The method includes (i) the fabrication of an imprint template (master), which consists of a photoresist deposited on a metal plate; (ii) the thermoembossing of the reactor features into polymer sheets; (iii) the activation of the embossed and planar thermoplastic surfaces;...

Since conventional cooling systems with channels are not adequate to achieve a high aspect quality short cycle time, better concept has be used control the fast variation of temperature in mold, close injected part. Recently, advanced manufacturing technologies like 3D-printing, rapid heat molding developing, using for example lattice structures as exchanger inside mold. Our work proposes an ex...

This contribution reviews elastomeric materials with photo-actuation behavior with emphasis on thermoplastic elastomers and their composites. The principles of the photo-actuation and the main factors affecting the photo-actuation phenomena of thermoplastic elastomer materials are discussed in detail. The well-performing photoactuating systems involving both statistical and block copolymers-bas...
