Easy-to-Form Polystyrene

Easy-to-Form Polystyrene

Often fabricated into signs, packaging, and light duty housings, polystyrene is easy to thermoform.

Multipurpose Plastic Selector Packs

Packs include one 2” square of ABS, Delrin® acetal, LDPE, HDPE, UHMW, nylon, cast nylon, polyester, polystyrene, Rexolite polystyrene, and Noryl PPO.

Slip-Resistant Shim Plates

The textured surface of these thick shims keeps them from sliding apart when stacked. Use them to align cabinets, doors, and windows, or for other rough leveling.

Breakaway Shim Plates

These thick shims are scored to make size adjustments easy—break off the excess shim for a custom fit around fasteners or corners. Use them to align cabinets, doors, and windows, or for other rough leveling.

Moisture-Resistant
Low-Temperature Rigid
Polystyrene Foam Insulation Sheets
