A parking lot in July is one of the toughest durability benches in the automotive industry. Surface temperatures on a dark instrument panel climb far above ambient, and ultraviolet radiation keeps working on every polymer chain it can reach. Parts that looked flawless ...

Pick up a soft-grip tool handle, peel the backing off a pressure-sensitive label, or press a thumb into the sole of a running shoe, and there is a fair chance you are touching a styrenic thermoplastic elastomer. These materials have quietly become the default answer wh...

SEPS, short for styrene-ethylene-propylene-styrene, sits at the high-performance end of the styrenic block copolymer family, and it behaves quite differently in the barrel from its unsaturated relatives. Ask anyone who runs it every day and you will hear the same numbe...

Styrene butadiene styrene block copolymer—commonly known as SBS—is one of the most versatile thermoplastic elastomers (TPE) in modern manufacturing. It combines the processing convenience of a thermoplastic with the elasticity and resilience of rubber, which is why...

Styrenic block copolymers (SBCs) represent one of the most versatile families in the thermoplastic elastomer (TPE) world. Combining the elasticity of rubber with the easy processability of thermoplastics, they have become indispensable in industries ranging from adhesi...

A purchasing manager evaluating SBS block copolymer for a hot-melt adhesive line usually asks two questions before approving a trial batch: will the grade hold its shear strength at the application temperature, and will the supplier deliver the same performance on the ...

At a pavement marking installation site, workers heat a thermoplastic mixture to roughly 200 °C and extrude it onto the road surface. The material cools quickly into a solid, reflective line. Yet many of these lines lose their brightness within three years, while othe...

A marking crew heats a dry blend of binder resin, pigment, glass beads, and mineral filler to roughly 200°C, extrudes it onto the lane line at a wet-film thickness of about 2 mm, and traffic runs over the line the same afternoon. Thermoplastic pavement marking materia...

If you are evaluating elastomers and you typed "SEPS styrene ethylene propylene styrene hydrogenated SBS or SIS" into a search engine, you are probably trying to draw a line between several block copolymers that look similar on paper but behave differently in productio...

When a hot-melt pressure-sensitive adhesive must coat a heat-sensitive film at 150 °C, build tack quickly, and hold a label on a curved surface for years, styrene isoprene styrene block copolymer (SIS) is usually the first polymer a formulator reaches for. The reason ...
