When sourcing co-extrusion and tri-extrusion profiles, start with what each material zone must do. Then ask suppliers to explain the proposed grades,

Crosshead extrusion coating applies a polymer layer around a pre-existing core as it passes through an extrusion head. The core and molten polymer ent

Who This Guide Is For (and What It Leaves Out) Most problems with custom extruded plastic tubing start before the first metre comes off the line. They

Thermoplastics soften when heated and solidify when cooled. Conventional thermosets form a permanent crosslinked network during curing and cannot subs

A thermoplastic polymer softens when heated and solidifies when cooled, allowing it to be shaped into continuous plastic profiles. Common candidates i

PEEK O rings should be assessed by their function, material grade and operating conditions. A material datasheet can help compare candidates, but it d

PEEK seal performance depends on more than the mechanical strength or temperature resistance of the polymer. For a high-pressure application, the crit

A ULTEM datasheet can show 217°C, 201°C, 190°C and 170°C for the same resin. Each number answers a different question. If an engineer

Assessing pfa material properties requires looking past standard marketing datasheets. Engineers must understand the physical limits of the polymer un

ABS acrylic coextrusion brings an ABS base and an acrylic, or PMMA, surface layer together through a die. It may be worth evaluating when a part has b

An ABS profile can meet its cross-sectional dimensions and still fail to fit along its length. It may bow, curve sideways or twist after it leaves the
