Descrição
ASTM1238 ISO 1133 Plastic Melt Flow Index Testing Machine design and manufacture in accordance with GB/T 3682-2000 thermoplastic melt mass flow rate and melt volume flow rate Determination.
ISO 1133-2005 Plastics Determination of the melt mass-flow rate(MFR) and melt volume-flow rate(MVR) padrões.
It is not only suitable for polyethylene, polipropileno, poliestireno, ABS resin with lower melting temperature, such as plastic test, can also be applied to high temperature of polycarbonate, plástico de flúor, nylon engineering plastics such as testing, therefore is widely used in plastic production, produtos plásticos, petrochemical and other industries as well as the relevant universities and colleges, unidades de investigação científica.
