2009年8月1日 · Rimar Salt (m/z 299) is the predominant peak in the mass spectrum due to its much higher concentration. Even in the presence of the high Rimar Salt concentration, KSS ( m / z 297) can also be seen, however, any information on isotopic abundances due to sulfur on the basis of M + 2 is lost due to the presence of the Rimar Salt anion at the same ...

2023年12月15日 · Some highly used flame retardants (FR) are considered PFAS according to the European Chemicals Agency classification, which are: PTFE and K Perfluorobutane sulfonate (KPFBS), commonly known as Rimar Salt. PTFE acts as an anti-drip, but in some formulations alone can provide sufficient flame retardancy.

2023年5月4日 · Marc Lebel, chief executive officer at FRX, told Design News that “a commonly used PFAS chemical known as KPFBS or Rimar Salt is used in many products made from polycarbonate in uses where there is a fire risk. The PFAS chemical can get into the environment, and potentially our bodies, during manufacture, during installation (if a sheet is ...

2006年3月1日 · The addition of alkali or alkaline earth metal salts of inorganic sulfur compounds in low concentration was found to be effective in flame-retarding aromatic polycarbonate as a special case. Sodium and potassium perfluoroalkanesulfonic acids (also known as “Rimar salt”) were found effective in amounts well under 0.05–0.5% PPFBS [1].

2023年4月24日 · The company said it has demonstrated the ability to replace the PFAS chemical KPFBS, otherwise known as Rimar salt, allowing resin producers and compounders specialising in PC blends and alloys to offer products without the material.

2023年4月20日 · OEMs such as Apple and IKEA have committed that their products be PFAS free in PC and its blends, that has meant replacing the well-known PFAS chemical KPFBS, otherwise known as Rimar salt, which FRX has already demonstrated a capability to do.

Arichem KSS-FR is a superior ame retardant for transparent polycarbonate compounds. It can also be used in translucent and opaque polycarbonate formulations. The Arichem KSS-FR polycarbonate formulation below has been shown to meet Underwriters Laboratories (UL) 94 V0 ame retardant requirements at a specimen thickness of 3.2 mm (1/8”).

2013年8月20日 · 磺酸盐阻燃剂有催化降解的作用，他的阻燃机理就是这样，2%的用量太多了，一般rimar用0.05-0.1%，其他品种是rimar的3-5倍，用量多的问题是严重降解并且容易吸水。
