Kydex® P88 Extrusion Compound

Subcategory: Thermoplastic

Material Notes:
Low smoke profile extrusion compound for mass transportation

Applications: Kydex P88 is specifically designed for mass transit railcars, subway, and bus interiors where there are FTA or FRA flammability requirements.

Features: Extruded profiles made with P88 are extremely resistant to harsh chemicals and solvents and to cleaning agents. P88 offers excellent fire retardancy including compliance to the FTA and FRA recommended fire practices under ASTM E162 and E662. Extrusions made with P88 are easy to clean. Motor Vehicle Safety Standards (MVSS 302) pending. Radiant Panel: 35 as per ASTM D162. Smoke Generation: 165.4 ASTM E662.

Processing: This compound should be processed using rigid PVC extrusion equipment under standard PVC operating conditions. Barrel temperatures in an extruder should be set at 166-171°C and adapter and die temperatures should be 171-177°C. Screw RPMs of 23 to 33 are typical. Typically single screw extruders are used for pelletized material and conical twin screw extruders for powder. Unlike other thermoplastic resins, pre-drying is not required.
