Working with LCP-GF30 LOWDK
Is LCP-GF30 easy to machine?
Machines cleanly with sharp PCD or carbide tools at high speed and light feed, but glass fiber is abrasive and the skin layer fibrillates — avoid dull tools and use climb milling with air cooling.
Can LCP-GF30 be welded?
Weak weld/knit lines and poor ultrasonic welding due to the oriented skin; use laser transmission welding, adhesive bonding with surface treatment, or design mechanical/insert-molded joints instead.
Can LCP-GF30 be formed, bent or molded?
Dry 4 h at 140–150 °C, mold at 300–340 °C (Type I 350–400 °C) with 60–150 °C tools, high injection speed and small gates; extremely low viscosity fills 0.2 mm walls but flashes easily, so vent and clamp precisely and orient gates to control fiber-direction shrinkage.
What surface finishes work on LCP-GF30?
Accepts vacuum metallizing, electroless Cu/Ni plating (LDS or etched grades) and laser marking; painting/printing needs plasma or flame pretreatment because of the low-energy, chemically inert surface.

LCP-GF30 LOWDK — frequently asked
What is LCP-GF30 LOWDK used for?
LCP-GF30 LOWDK is typically used for structural electrical connectors, reflow-compatible surface-mount parts, precision brackets and chemical-resistant fittings. In short: stiffest general-purpose LCP; reduced anisotropy versus unfilled; brand-independent 30 % glass grade.
What is the tensile strength of LCP-GF30 LOWDK?
LCP-GF30 LOWDK has a typical tensile strength of 160 MPa (23.2 ksi) — stronger than 96% of polymer grades. Strength varies by condition: see the 6 listed tempers.
Is LCP-GF30 LOWDK easy to machine?
Reasonably — machinability is rated good (55/100, worse than 64% of polymer grades). Machines cleanly with sharp PCD or carbide tools at high speed and light feed, but glass fiber is abrasive and the skin layer fibrillates — avoid dull tools and use climb milling with air cooling.
Can LCP-GF30 LOWDK be welded?
Not readily — weldability is rated poor (25/100). Weak weld/knit lines and poor ultrasonic welding due to the oriented skin; use laser transmission welding, adhesive bonding with surface treatment, or design mechanical/insert-molded joints instead.
What surface finishes work on LCP-GF30 LOWDK?

What is the maximum service temperature of LCP-GF30 LOWDK?
LCP-GF30 LOWDK is rated for continuous use to about 220°C (428 °F), and briefly to 280°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
