Grade: MX004
Formula: PMP TPX®
Form: Foil/Film/Sheet
Material: Polymethylpentene (PMP, TPX™)
Commodity: Polymers
MX004 Polymethylpentene (PMP) Film is a thermoplastic polyolefin used in industrial applications and scientific research, offering advantages for microfluidics, biosensing, and optical applications. With 94% transparency and high oxygen permeability, it is ideal for organ-on-a-chip and cell culture devices requiring precise oxygen control. Commonly referred to as TPX™, this material provides excellent chemical resistance and low shrinkage, making it suitable for manufacturing micro-optical components like waveguides and biochips, high-precision prototyping in photonics and lab-on-a-chip systems. MX004 also provides thermal stability up to 170°C, making it reliable for various laboratory applications, including biosensing and drug development, where consistent performance and reproducibility are essential for advanced research.
