The innovative METTLER TOLEDO dropping point systems determine dropping and softening points of pitch, asphalt, polymers, resins, waxes and many more materials with full automatic operation. A temperature where the bag will begins to experience noticeable change in physical properties called softening point. The temperature at which state change from solid to liquid called melting point.

The softening point is the temperature at which a material softens beyond some arbitrary softness.^[1] It can be determined, for example, by the Vicat method (ASTM-D1525 or ISO 306), Heat Deflection Test (ASTM-D648) or a ring and ball method (ISO 4625 or ASTM E28-67/E28-99 or ASTM D36 or ASTM D6493 - 11). A ring and ball apparatus can also be used for the determination of softening point of bituminous materials.^[2]

Mar 23, 2014 Softening point. The softening point is the temperature corresponding to a viscosity of 10 7.6 Poise (Bullseye & Wiki) or maybe 10 7.65 poise (Britannica). I didn’t figure out why I found two definitions for the softening point. At this viscosity glass softens sufficiently to be worked. Jun 05, 2012 The innovative METTLER TOLEDO dropping point systems determine dropping and softening points of pitch, asphalt, polymers, resins, waxes.

A vicat softening point test uses a needle pressing down onto a sample with a specified weight on the needle. Samples are placed in an oil bath and heated slowly at specified rates until the needle depresses a certain distance into the test material. The softening point is the temperature where the needle penetration reaches the specified distance. What is the relation with softening point? I am having a mixture of solid materials which is to be heated up and pored to make a layer of 5 inches broad and 5 mm thick. The material is allowed to. Softening point by a Vicat-type technique Summary The TMA 4000 has been evaluated over a wide range of applications including determining the melting and softening points of organics, metals, plastics and ceramics. It has the sensitivity to detect weak transitions or melting of thin layers, and the dynamic range to follow melting phenomena.
