Engineering ThermoPlastic Vulcanizates (ETPV)
Engineering Thermoplastic Vulcanizates (ETPV) are a class of advanced thermoplastic elastomers (TPEs) that combine the properties of thermoplastics with the resilience of vulcanized rubber. They are formed by dynamically crosslinking an elastomer phase (such as EPDM or NBR) within a thermoplastic matrix (such as polyamide, PBT, or other engineering plastics).
StructureThe structure of Engineering Thermoplastic Vulcanizates (ETPV) consists of a finely dispersed, dynamically crosslinked elastomer phase embedded within a continuous thermoplastic matrix. The elastomer phase, typically made of materials such as EPDM (ethylene propylene diene monomer) or NBR (nitrile butadiene rubber), undergoes vulcanization during melt processing, forming a stable rubber network. This crosslinked rubber phase provides ETPVs with high elasticity, resilience, and excellent mechanical properties. The thermoplastic matrix, often composed of engineering polymers like polyamide (PA), polybutylene terephthalate (PBT), or polyphenylene sulfide (PPS), serves as the continuous phase, giving the material its thermoplastic processability and structural integrity. The intimate interaction between the rubber and thermoplastic phases results in a material that exhibits both the flexibility of elastomers and the durability of engineering plastics. This unique microstructure allows ETPVs to retain their shape after deformation while also being reprocessable and recyclable like conventional thermoplastics.
PropertiesEngineering Thermoplastic Vulcanizates (ETPV) exhibit a unique combination of properties that make them highly versatile for demanding applications. They possess excellent elasticity and flexibility due to their dynamically crosslinked elastomer phase, while the thermoplastic matrix provides high mechanical strength, dimensional stability, and ease of processing. ETPVs offer superior resistance to heat, chemicals, and oils compared to conventional thermoplastic elastomers, making them suitable for high-performance environments such as automotive and industrial applications. They also demonstrate excellent wear and fatigue resistance, ensuring long-term durability under dynamic loading conditions. Unlike traditional rubber materials, ETPVs can be processed using standard thermoplastic techniques like injection molding and extrusion, which enhances manufacturing efficiency. Additionally, they maintain their mechanical integrity across a wide temperature range, making them ideal for applications requiring both flexibility and structural robustness.

Expandable PolyStyrene (EPS)
Expanded Polystyrene (EPS) is a rigid, closed cell, thermoplastic foam material produced from solid beads of polystyrene, which is polymerised from styrene monomer and contains an expansion gas (pentane) dissolved within the polystyrene bead. Each solid polystyrene bead contains small amounts of gas which expand when heat (in the form of steam) is applied, thus forming closed cells of EPS. These expanded cells occupy approximately 40 times the volume of the original polystyrene bead, and so with a second heat treatment using a mould, large EPS blocks can be moulded into specific customised shapes.
Expanded PolyStyrene structureThe structure of Expanded Polystyrene (EPS) consists of tiny, closed-cell foam beads made of polystyrene. These beads are expanded using heat, causing them to expand up to 50 times their original size. Also each bead contains air pockets.
Expanded PolyStyrene propertiesExpanded polystyrene (EPS) is found to be the most commonly used polymer core. This is because it is lightweight, resistant to moisture and also it has a long life. Studies have concluded that softening of EPS starts when exposed to temperatures ranging from 100°C to 120°C. In the process of flashovers, EPS melted about 160°C and then vaporized, producing poisonous gases at a temperature of 275°C. EPS is an inert, low density hydrocarbon-derived thermoplastic which contains several spherical beads with 2 percent polystyrene and 98 percent air
