Thermoplastic elastomers (TPEs) are useful in various engineering and healthcare applications. A new fully biobased polyamide TPE (PA36,9) with medium hardness is reported. The elastomer synthesized using a fatty dimer amine azelaic acid, via one-pot melt condensation polymerization. resulting shows melting temperature of 83.6 °C, (Shore A/Shore D = 90/35), large elongation at break (1220%), go...

The size, shape and distribution of different phases in thermoplastic polyolefin (TPO) blends and composites are critical to the properties of the materials, but can be difficult to characterise. Here we report the combination of heavy metal staining and focused ion beam - scanning electron microscopy (FIB-SEM) to reveal the three-dimensional (3D) structure of an elastomer-modified poly(propyle...

The residual levels and migration behavior of volatile substances were detected using HS-GC/MS for acrylonitrile-butadiene-styrene copolymer (ABS) toys, thermoplastic elastomer toys, and rubber toys made from 1,3-butadiene and styrene found on the Japanese market. The maximum residual level of these volatile substances was 2600 μg/g of styrene in ABS toys. In particular, the levels of known car...

Thermoplastic Elastomers (TPE) are materials, which combine the advantages of elastomers and thermoplastics. TPE is not only used as replacement for thermoplastics. More and more parts, formerly made of rubber like CVJ boots and hydraulic seals, are nowadays made of TPE. Since the mechanical behavior of TPEs is different to elastomers, the design of TPE parts cannot be copied directly from thei...

This study investigates the addition of ground tire rubber (GTR) into virgin polyamide 6 (PA6) to produce thermoplastic elastomer (TPE) blends. In particular, a wide range GTR concentration (0–100% wt.) was possible by using simple dry blending technique materials in powder form followed compression molding. The molded samples were characterized terms morphological (scanning electron microscopy...

Attempts have been made for the first time to produce a friction material with thermal sensitive modulus by the inclusion of combined plastic/rubber properties of thermoplastic elastomers (TPE) as viscoelastic polymeric materials into the formulation for the purpose of increasing the damping behavior. In order to evaluate the viscoelastic parameters such as loss factor (tan δ) and elastic m...
