CYROLITE MD L40 delivers the highest melt flow rate (26.0 g/10min) in the MD series — enabling exceptional thin-wall injection molding with ≥87.7% UV transmission and <1% haze.
CYROLITE MD L40 is a high flow UV transparent medical diagnostic acrylic polymer specifically designed for thin-wall injection molding applications requiring UV spectroscopy. With a melt flow rate of 26.0 g/10min — the highest in the CYROLITE MD series — this material delivers exceptional flow characteristics for filling thin-wall, complex diagnostic molds with rapid cycle times. It offers ≥87.7% UV transmission at 340nm, 92% total light transmission, and haze below 1%, ensuring precise UV spectroscopic analysis.
CYROLITE MD L40 contains medium levels of lubricant to enhance mold release and processing performance. It provides excellent dimensional stability with flexural modulus of 3.0 GPa and tensile modulus of 3.2 GPa. Meeting USP Class VI (colorless) and ISO 10993-1 biocompatibility requirements, this material is suitable for patient-contact diagnostic devices. Processable on standard injection molding equipment with 3-zone general purpose screws. Typical applications include thin-wall cuvettes, rotors, well plates, diagnostic test packs, microfluidics, and crystallography trays where high flow and UV transparency are critical.
