diX Film Properties

     diX C: Standard Grade: Useful for a wide range of applications
Exceptional gas-barrier and mechanical properties. Excellent electrical and chemical properties. Superior thickness uniformity and high efficiency film growth on target substrate. Thickness control in the micron range and below. Meets standards for Mil-I-46058C, IPC-CC-830B, UL94 V-0, FDA Drug and Device Master files, USP Class VI biocompatibility testing, and ISO 10993 for medical devices. Thermal stability: 120 (in Air) 260 (in oxygen free environments)
Advantages of diX C over conventional Parylene C - Minimal evaporation residue and staining on the inside of the coating machine for easier maintenance because of the higher purity dimer. No offensive odors due to decomposition of impurities. High purity dimer creates a high purity polymer film with high gas barrier properties. Our unique manufacturing process achieves high purity exceeding 99%, providing the following advantages:
 
     diX N: Non-Halogen Grade
  Exceptional electrical properties (low dielectric constant and low dissipation factor). Deep crevice penetration and lubricity - ideal for silicone rubbers and other rubbers. Excellent adhesion to silicone rubbers. Excellent thickness uniformity and control to 1m or below. USP Class VI biocompatibility tested. Thermal stability: 100 (in Air) 240 (in oxygen free environments)
