High-Flow PBT for Thin-Wall Parts

Two new high-flow PBT grades, launched under the Pocan XtremeFlow banner, are aimed at complex thin-wall parts that must retain their shape at temperatures up to 140 C/284 F.

Two new high-flow PBT grades, launched under the Pocan XtremeFlow banner, are aimed at complex thin-wall parts that must retain their shape at temperatures up to 140 C/284 F. Pocan DP B 3225 XF (20% glass) and DP B 3235 XF (30% glass) reportedly give 30% longer flow and up to 30% faster cycles, owing in part to the ability to reduce melt temperatures. The new materials also offer improved hydrolytic resistance, greater toughness—especially at low temperatures—and lower density. Electrical, automotive, and appliance uses include plugs, edge connectors, and parts subject to mechanical stress such as gear plates. With strong hydrolytic stability, the materials are suitable for airbag plugs and connectors for auto engine compartments.
