Description

Parylene N is a high-performance, linear poly(p-xylylene) polymer known for its exceptional dielectric strength, chemical inertness, and ability to form ultra-thin, uniform, and pinhole-free conformal coatings. This material is critical for providing reliable, long-term protection to sensitive components in demanding environments. It is essential for manufacturers in the electronics, medical device, aerospace, and automotive industries seeking to enhance product durability and performance.

Application

• Conformal Coating for Electronics: Provides superior moisture, chemical, and dielectric barrier protection for printed circuit boards (PCBs), sensors, and micro-electromechanical systems (MEMS).
• Medical Device Encapsulation: Used to coat implantable devices, surgical tools, and diagnostic components due to its biocompatibility, purity, and ability to form uniform, protective layers.
• Aerospace & Defense Component Protection: Shields critical avionics, connectors, and assemblies from harsh conditions including humidity, salt fog, and thermal cycling.
• Automotive Electronics: Protects engine control units (ECUs), sensors, and LED assemblies from under-hood environments, fuels, and lubricants.
• Hybrid Microelectronics: Serves as a dielectric interlayer and protective coating in hybrid circuits and multi-chip modules.
• Cultural Heritage Preservation: Used to stabilize and protect delicate artifacts, papers, and metals from environmental degradation.
• Optics and Photonics: Coats optical fibers, lenses, and laser components where clarity, durability, and precise thickness control are required.

Quality Control

Our Parylene N is manufactured and controlled under a stringent quality management system to ensure batch-to-batch consistency and high performance. We provide comprehensive analytical data, including intrinsic viscosity, melting point, and residual monomer content. Certificates of Analysis (COA) detailing purity and key physical properties are available for every batch upon request.

Storage

Preserve in a tightly closed container, protected from light. Store the raw dimer powder in a cool, dry place at room temperature (15-25°C). The storage area should be well-ventilated and free from sources of ignition. For long-term stability, store under an inert atmosphere such as nitrogen or argon to prevent oxidation.
