| Grade · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness |
|---|---|---|---|---|---|

Glass + mineral hybrid, low-warpage / low-anisotropy | Choose for flat, large or thin plate-like parts where flow/transverse shrinkage difference and warpage must be minimized. | 130 | 1.8 | ||

15% glass-fiber reinforced | Choose for very thin-wall connectors where flow must stay high but some stiffness and reduced anisotropy are needed. | 150 | 2.6 | ||

What is Sumikasuper?
Sumikasuper is a liquid-crystal polymer brand from Sumitomo Chemical, offered natural and in glass (GF15-GF40), glass/mineral, mineral, carbon, ESD, lubricated, high-heat, low-dielectric, white, LDS and medical grades. It is widely stocked for precision electronics parts because of its high flow and dimensional accuracy in thin-wall injection molding, with 1.62 g/cm3 density, 160 MPa tensile strength, 2.2 % elongation, 14 GPa modulus, 220 C maximum service temperature and a machinability score of 45. Elongation is low, weld lines are weak and machining causes skin delamination, so net-shape molding is preferred; Laperos is the closest equivalent. Sumikasuper has a density of 1.62 g/cm³ (0.0585 lb/in³), heavier than 94% of polymer grades. Its glass-transition temperature is 120°C (248 °F). Sumikasuper has a tensile strength of 160 MPa (23.2 ksi), stronger than 96% of polymer grades. Elongation at break is 2.2% and the elastic modulus is 14 GPa (2.03 Msi).

Working with Sumikasuper
Is Sumikasuper easy to machine?
Machinable with sharp PCD/carbide tooling and light feeds, but the fibrillar skin delaminates and glass is abrasive — design for net-shape molding wherever possible.
Can Sumikasuper be welded?
Ultrasonic and vibration welds are weak because of skin-core orientation; laser transmission welding, snap fits, heat staking or adhesive with plasma pretreatment are preferred.
Can Sumikasuper be formed, bent or molded?
Dry 3–4 h at 130–150 °C, mold at 340–370 °C melt / 80–150 °C tool with fast injection and generous venting; fills 0.2 mm walls but weld lines and flash need gate-location and 0.005–0.01 mm tool fit control.

What surface finishes work on Sumikasuper?
Low surface energy means paint and adhesives require plasma or corona pretreatment; LDS grades accept electroless Cu/Ni/Au, and pigmented white grades keep reflectance after reflow.

What surface finishes work on Sumikasuper?
Low surface energy means paint and adhesives require plasma or corona pretreatment; LDS grades accept electroless Cu/Ni/Au, and pigmented white grades keep reflectance after reflow.

What is the maximum service temperature of Sumikasuper?
Sumikasuper is rated for continuous use to about 220°C (428 °F), and briefly to 300°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
