face mask melt-blown nonwoven Melt Flow Index MFI Testing Equipment

PP (polypropylene), a non-woven spray-melt cloth material in the mask, generally has a fluidity of 1000 ~ 2000g / 10min. It is a super-high-fluidity plastic. It cannot be tested at all by the melt index meter of the ordinary mass method, and we should A volumetric melt index instrument was used for testing.

Melt Flow Tester, Melting Point Apparatus

It is used to measure the temperature and load of various plastics and resins in the state of viscous flow, and the melt flow rate MFR value of the standard die every 10 minutes. It is suitable for polycarbonate, polyarylsulfone, and fluorine with a high melting temperature. Engineering plastics such as plastics and nylons are also suitable for polyethylene (PE), polystyrene (PS), polypropylene (PP), ABS resin, polyoxymethylene (POM), polycarbonate (PC) resins, etc. with low melting temperature The plastic testing is widely used in plastic production, plastic products, petrochemical and other industries as well as related institutions, scientific research units and commodity inspection departments.
