PEI-SABIC LNP Thermocomp EC006
To substitute heavy die-cast zinc and aerospace-grade aluminum alloys in load-bearing structural mechanisms without adding weight or losing structural rigidity, SABIC’s LNP™ THERMOCOMP™ Compound EC006 provides an uncompromising solution. This 30% carbon fiber reinforced polyetherimide (PEI-CF30) grade delivers a massive dry-as-molded (DAM) tensile modulus of 20,200 MPa and an ultimate tensile strength of 215 MPa. Jucheng Precision, operating under IATF 16949 and ISO 9001 certified systems, specializes in high-temperature molding of EC006. Utilizing 5-axis CNC-machined H13 steel toolings, we control its highly anisotropic shrinkage (0.1% parallel, 0.5% perpendicular) and prevent surface fiber-floating, delivering defect-free parts verified by Zeiss CMM.

PEI-SABIC LNP Thermocomp EC006 Tooling & Carbon Fiber Processing Guide
Molding an ultra-high performance carbon-fiber reinforced PEI like LNP EC006 requires strict moisture control and optimized gating to prevent abrasive tool wear and warpage:
Powder Metallurgy Hardened Tool Steel
30% short carbon fibers act as an aggressive grinding agent under high injection pressures and melt viscosity. Jucheng’s tooling division prevents gate and cavity erosion by using premium CPM powder metallurgy tool steels or hardened H13/S136 steel (HRC 54–56) with PVD ceramic coatings.
Managing Anisotropic Shrinkage & Warpage
LNP EC006 shrinks exceptionally low along the flow (typically 0.10%) but higher perpendicular to the flow (0.50%). We conduct detailed Moldflow analysis during DFM to locate gates, ensuring uniform fiber orientation to prevent structural warping.
Pressurized Oil Mold Temperature Control
We maintain mold temperatures at 80°C–120°C (176°F to 248°F) using pressurized water heaters. High mold temperatures maximize surface gloss, reduce weld lines, and prevent surface carbon-fibers from floating, ensuring a smooth and non-fibrous finish.
Desiccant Drying Protocol (Hydrolysis Prevention)
PEI is highly sensitive to moisture at high melt temperatures. Wet molding results in rapid hydrolytic chain cleavage, causing severe splay, gas bubbles, and a major drop in impact strength. We desiccant dry LNP EC006 resin at 120°C–150°C (248°F–302°F) for 4 hours, keeping moisture below 0.02%.
