High Temperature Materials
Most materials used at Ironwood Plastics are engineering grade materials. Running high temperature engineering grade materials requires special provisions that we handle every day. Most of these materials require mold temperatures exceeding 200F and many are approaching 400F to obtain the proper crystallinity. We accomplish this with the use of hot oil or steam circulating through the mold and braided steel lines. Some of the materials we run that fall into the "high temp" category include:
-
(PEI) Ultem
-
(LCP) Vectra
-
(ETFE) Tefzel
-
(PPA) Amodel
-
(PPS) Ryton, Fortron
-
(PES) Raydel
-
(PEEK) RTP, Thermocomp
-
(PSU) Udel
