HVAC
DuPont™ Suva® refrigerants Offer a wide selection of HVAC and low temerature cascade refrigerants for both existing and new systems. DuPont Refrigerants offer the semiconductor industry high cooling capacity, lowest compressor discharge temperature and lowest cost CFC retrofit options. DuPont has been the leader in the HVAC and refrigeration industry with over a 50 year track record of stable supply of these critical system gases.

Contamination Control Analyses of process fluid composition, determinations of particulate and bacterial levels, and other laboratory procedures are critical steps in manufacturing semiconductors. Fluid chemistries must be analyzed and kept on specification to maintain yields. For accuracy and repeatability, labware and equipment must not react with or contaminate the samples being studied or the reagents. We offer several products to maintain contamination control.

DuPont™ Vertrel® specialty fluids DuPont™ Vertrel® specialty fluids have proven to be the ideal solution for the critical demands of the electronics industry because of their low surface tension and ability to wash away contaminants such as solder paste in a quick and effective manner.
Filters made with DuPont™ Teflon® resins For removing particulate from fluids, Teflon® PTFE is used as a filter medium where extremely high chemical resistance and purity are required. Teflon® PFA HP or Teflon® PFA HP Plus is used for chemically resistant, high-purity filter housings.

Fire Extinguishants DuPont fire extinguishants are intended to prevent or extinguish fires in situations where conventional extinguishing agents such as water, dry chemical, and carbon dioxide are unacceptable because they may cause collateral damage, significantly interrupt business productivity, or present a safety risk.

DuPont™ FE™ family of clean agent fire extinguishants DuPont developed the FE family of clean agent fire extinguishants, designed to protect people, high-value assets, and business continuity. The FE clean agent fire extinguishants are safe for people, electrically nonconductive, noncorrosive, and free of residue. Most do not contain chlorine or bromine and therefore have zero ozone depletion potential.

Exhaust Ducting
DuPont™ Teflon® coatings The versatility of DuPont™ Teflon® coatings allow almost unlimited application to a wide variety of part sizes and configurations, always adding value far beyond the inherent nonstick qualities. Our coatings offer temperature resistance (150°C), chemical resistant, superior corrosion resistance, excellent dielectric stability, and a low coefficient of friction. DuPont has the worldwide resources to help you solve your semiconductor manufacturing coating problems.

Waste Handling Piping
DuPont™ Teflon® coatings Throughout the semiconductor industry's history, the  outstanding chemical, temperature and corrosion resistance of, DuPont™ Teflon® has delivered the performance needed to become the material of choice for tools, equipment and systems that come in contact with aggressively reactive, high-purity fluids.
