How to Reduce Exposure to CAS 106-94-5 n-PB, 1-Bromopropane Solvent Substitution – Using Safer Alternatives The best way to reduce exposure is to switch to products that do not contain n-Propyl Bromide, nPB. There are lots of nonflammable solvents with high Kb values that do not require stabilizers, alkalinity testing and frequent, expensive disposal costs. […]
n-Propyl Bromide (nPB) also known as 1-Bromopropane or (1-BP), CAS # 106-94-5 is a brominated hydrocarbon solvent used in a variety of industrial applications, e.g. hand wipe, vapor degreasing, Ultrasonic cleaning, non-destructive inspection and aerosol dispensers commonly consumed for cleaning and degreasing among Aerospace, Electronics, Metal Working, Precision Optics, Asphalt Extraction (Bituminous Asphalt) and […]
n-Propyl Bromide Exposure Risks In March 2013, National Toxicology Program (NTP) and a panel of experts unanimously voted to list 1-bromopropane, also known as nPB, CAS # 106-94-5, as a “reasonably anticipated to be a human carcinogen,” based on the animal studies presented by NTP to include as part of their 13th Report on Carcinogens […]
So how much SHOULD you pay to replace AK-225? That depends on several factors such as Nonflammable? Solvency (Kb value)? Need for azeotropes? Tolerance of chlorinated solvents? Toxicity exposure limits (PPM)? VOC content? In order to continue to operate with nonflammable solvents for your degreasing applications you have limited choices. Methylene Chloride, TCE and PERC […]
Still using AK-225 (HCFC-225ca/cb)? Not for much longer. Depending on who you ask in the industry and US government regulatory agencies the official mandated phase-out date is December 31, 2014 for HCFC-225 commonly known as Asahiklin AK-225 for precision cleaning, 225AES, 225T and 225ATE for defluxing, drying where alcohol azeotropes are used, 225DH for displacement […]
