'''Polistirena''' atau '''polistyren (PS)''' adalah sebuah [[polimer]] dengan [[monomer]] [[stirena]], sebuah [[hidrokarbon]] [[cair]] yang dibuat secara komersial dari [[minyak bumi]]. Pada suhu ruangan, polistirena biasanya bersifat [[termoplastik]] padat, dapat mencair pada suhu yang lebih tinggi. Stirena tergolong senyawa [[aromatik]].<br />
<br />
Polistirena pertama kali dibuat pada 1839 oleh [[Eduard Simon]], seorang [[apoteker]] [[Jerman]]. Ketika mengisolasi zat tersebut dari [[resin]] alami, dia tidak menyadari apa yang dia telah temukan. Seorang kimiawan organik Jerman lainnya, Hermann Staudinger, menyadari bahwa penemuan Simon terdiri dari rantai panjang molekul stirena, yang adalah sebuah polimer plastik.<br />
<br />
Polistirena padat murni adalah sebuah plastik tak berwarna, keras dengan fleksibilitas yang terbatas yang dapat dibentuk menjadi berbagai macam produk dengan detail yang bagus. Penambahan karet pada saat polimerisasi dapat meningkatkan fleksibilitas dan ketahanan kejut. Polistirena jenis ini dikenal dengan nama High Impact Polystyrene (HIPS). Polistirena murni yang transparan bisa dibuat menjadi beraneka warna melalui proses ''compounding''. Polistirena banyak dipakai dalam produk-produk elektronik sebagai casing, kabinet dan komponen-komponen lainya. Peralatan rumah tangga yang terbuat dari polistirena, a.l: sapu, sisir, baskom, gantungan baju, ember.<br />

== Proses manufaktur ==<br />
Polistirena dapat dibentuk menjadi berbagai macam produk dengan cara:<br />
* [[Injection molding]]<br />
* [[Ekstrusi]]<br />
* [[Pembentukan termal vakum]]<br />
<br />
== Pemanfaatan ==<br />
Jenis-jenis polisterina dimanfaatkan sebagai [[Pengemasan|kemasan]]. Polistiren berorientasi banyak digunakan untuk kemasan [[buah]]-buahan dan [[sayuran]] karena mempunyai [[permeabilitas]] [[uap air]] dan gas yang tinggi. Bentuk lain seperti [[kopolimer]] stiren dengan karet [[1,3-butadiena|butadien]], kopolimer stiren dengan [[akrilonitril]] juga digunakan untuk kegunaan yang sama. Sedangkan bentuk kopolimer akrilonitril butadien stiren (ABS) banyak digunakan untuk [[pembentukan termal]]. [[Nama dagang]] ABS di antaranya adalah Abson, Cycolac, Royalite dan Sulvac. ABS adalah [[termoplastik]] yang tidak transparan dan berwarna putih kekuningan.<br />
