PMP Film

Polymethylpentene (PMP) Film, also known as TPX™, is a thermoplastic polyolefin that provides high visible light transmission (94%) and thermal stability up to 170°C, making it effective for fabricating micro-optical and photonic devices. Its chemical resistance and low shrinkage enable precise replication of nanostructures down to 100 nm through hot embossing or molding processes. In research and laboratory environments, PMP Film supports the development of subwavelength optics, grating couplers, and integrated biosensors. Its optical clarity and formability make it valuable for prototyping organ-on-a-chip systems, optical communication components, and low-cost biosensors, supporting scalable photonic and biomedical innovation.
