PMDETA(N,N,N',N',N"-PENTAMETHYLDIETHYLENETRIAMINE) Description: Appearance:colorless transparent liquid Content: min 99% Water content: max 0.25% CAS NO.: 3030-47-5 HS CODE: 292129 Country of origin: China Annual output: 500 tons PMDETA Applications. PMDETA catalyst is a highly active, pure liquid tertiary amine that is suitable for use as a blowing catalyst in a number of rigid and flexible polyurethane foam applications. ADVANTAGES: In model systems, PMDETA catalyst has proven to have catalytic activity equivalent to other established blowing catalysts for the urea reaction. However, PMDETA catalyst has a greater affect than established blowing catalysts on the urethane or gelling reaction. PMDETA catalyst is very effective in pour-inplace polyurethane systems (such as rigid appliance systems), which are based on MDI. At a use level of 1.5 php, PMDETA catalyst provides the necessary flowability and cure rates required in the production environment. PMDETA catalyst is also recommended for TDI, TDI/MDI and MDI HR flexible molded foams, as well as for use in integral skin and microcellular systems. It can also be as a raw material to make quaternary ammonium salt.

A KN95 mask is a particulate-filtering facepiece respirator that meets the Chinese National Personal Protective Technology Laboratory for KN95 classification GB2626-2019 of air filtration, meaning that it filters at least 95% of airborne particles.The mask with a strapless innovative design provides a complete perimeter seal with security and protection. What is the Difference Between an N95 & Kn95 Mask? However, there are some differences between N95 and KN95: 1. The Chinese government requires the kn95 disposable face mask manufacturer to run a special mask fit test on real humans with â?¤ 8% leakage to be certified. The china face mask kn95 standard does not require manufacturers to run fit tests. 2. N95 masks have slightly stricter requirements for pressure drop while inhaling. That means theyâ??re required to be slightly more breathable than KN95 masks. 3. N95s also have slightly stricter requirements for pressure drop while exhaling, which should help with breathability. In short, refer to the above datas, the china kn95 face mask disposable is more breathable than KN95 mask. Most of these differences are small and would be not noted by the civil mask user. There are many china kn95 face mask disposable manufacturers, but we are one of the best choices for you. For more information about disposable ppe kit, please feel free to contact us!

BaF2 window crystals or Barium Fluoride window crystals, with their extremely broad transmission range from the deep UV to LWIR spectrum, are prevalent for Infrared applications requiring additional transmission in the Ultraviolet region. BaF2 window crystals are excellent when being used for IR spectroscopes and as viewport windows for thermal imaging inspection in electric power facilities and petroleum industries. A low refractive index of 1.48 implies BaF2 windows have high transmission rates without anti-reflection coating. BaF2 window crystals has similar properties to CaF2, the difference mainly lies in that barium fluoride window is more resistant to highly energetic radiation, and with an equivalent thickness, the transmission range of BaF2 window extends approximately 1 micron further into the long-wave IR region than calcium fluoride. BaF2 window crystals could also accommodate high-temperature environments up to 800 â??. However, exposure to moisture will increase its sensitivity to temperature and reduce its transmission rate to UV lights.
