Stamylex® 2258 is a butene based linear low density polyethylene produced in a solution polymerisation process using a Ziegler - Natta catalyst.
This grade contains an additive package for thermal stabilization and a processing aid.

Characterized by good processing properties and toughness, Stamylex 2258 is used primarily to manufacture articles with extremely long flow paths and stringent warp requirements.

A high resistance to environmental stress cracking and its dimensional stability render Stamylex 2258 particularly suited for (domestic) applications, which require good resistance to the aggressive cleaning environment and high temperatures typically encountered, for example, in dish washing machines.
