Polyetherimide — commercially known as Ultem® (SABIC) — is the material that gets specified once the design requirements have been clarified by failure. It is not the cheapest engineering thermoplastic on the list. It is not the easiest to process.…
ASA plastics — acrylonitrile styrene acrylate — was engineered specifically to solve the outdoor durability problem that ABS cannot. By replacing ABS’s polybutadiene rubber phase (which contains UV-reactive carbon-carbon double bonds) with a saturated acrylic ester elastomer, ASA achieves approximately…
Polyetheretherketone occupies a performance tier that no other injection-moldable polymer reaches — a sustained service temperature approaching 260 °C, strength-to-weight ratio rivaling aluminum, resistance to virtually every industrial chemical except concentrated sulfuric and nitric acids, inherent biocompatibility validated for long-term…
Styrene acrylonitrile sits in a performance window that is genuinely underutilized in precision injection molding programs — better optical clarity and chemical resistance than GPPS, significantly more rigid and dimensionally stable than LDPE or PP, and less expensive than PC…
What happened? PET is a semi-crystalline polymer — and semi-crystalline polymers behave differently depending on whether they crystallize during molding or not. An engineer who has only worked with amorphous polymers like ABS or PC will encounter PET’s crystallization behavior…
PBT plastic — polybutylene terephthalate — is the material that has been answering these reliability demands in electrical and electronic applications for over four decades. Not because it is the strongest engineering thermoplastic, the stiffest, or the cheapest. But because…
POM plastic — formally known as polyoxymethylene, and widely sold under trade names like Delrin® and Celcon — occupies a well-defined space in the engineering thermoplastic lineup: harder than nylon, stiffer than polypropylene, and capable of dimensional tolerances that rival…
You chose acrylic because nothing else looks like it. 92% light transmittance — higher than crown glass. A refractive index of 1.49 that makes light guides glow with surgical precision. Inherent UV stability that lets outdoor signage stay crystal-clear for…
Your enclosure passed the drop test. The surface took paint without adhesion failures. The dimensional report came back clean on the first T1 submission. That’s what a well-executed ABS plastic program looks like — and it’s less common than it…
PC plastic is one of the highest-performance engineering thermoplastics available — and one of the most unforgiving when processed or specified incorrectly. Its combination of extreme impact resistance, optical clarity, and thermal stability is genuinely difficult to replicate with any…
