स्टाइरन इसके अंग्रेजी अर्थ का उदाहरण

Other typical uses for PIR foams include industrial and commercial pipe insulation, and carving/machining media (competing with expanded polystyrene and rigid polyurethane foams).

Solution styrene-butadiene rubber, a form of synthetic rubber.

The Oita Plant, the main manufacturing base, supplies SDK and other chemical companies with the basic materials for making acetyl derivatives, synthetic resin, synthetic rubber, and styrene monomers.

For nonpolar systems such as polystyrene in cyclohexane, phase separation has been observed in sealed tubes (at high pressure) at temperatures approaching the liquid-vapor critical point of the solvent.

Kraton polymers are styrenic block copolymer (SBC) consisting of polystyrene blocks and rubber blocks.

The tri-block with polystyrene blocks at both extremities linked together by a rubber block is the most important polymer structure observed in SBC.

If the rubber block consist of polybutadiene, the corresponding triblock structure is: poly(styrene-block-butadiene-block-styrene) usually abbreviated as SBS.

The microstructure of SBS consists of domains of polystyrene arranged regularly in a matrix of polybutadiene, as shown in the TEM micrograph.

The glass transition temperature (Tg) of the polybutadiene blocks is typically −90"nbsp;°C and Tg of the polystyrene blocks is +100"nbsp;°C.

If Kraton polymers are heated substantially above the Tg of the styrene-derived blocks, that is, above about 100"nbsp;°C, like 170"nbsp;°C the physical cross-links change from rigid glassy regions to flowable melt regions and the entire material flows and therefore can be cast, molded, or extruded into any desired form.

The polystyrene blocks form domains of nanometre size in the microstructure, and they stabilise the form of the moulded material.

Depending on the rubber to polystyrene ratio in the material, the polystyrene domains can be spherical or form cylinders or lamellae.
