HDT Vicat softening temperature Tester

The HDT Vicat Softening Point Apparatus is a testing instrument used to determine the softening point of a material. It is commonly used in the plastics industry to evaluate the heat resistance and thermal stability of polymers.

The apparatus consists of a heating bath, a test specimen holder, and a needle or a flat-ended plunger. The test specimen is placed in the holder and immersed in the heated bath. The temperature is gradually increased at a specified rate, and the needle or plunger is applied to the specimen at regular intervals.

The softening point is determined by observing the point at which the needle or plunger penetrates a specified distance into the specimen. This indicates the temperature at which the material starts to soften and lose its dimensional stability.

The HDT Vicat softening point apparatus is designed to meet international standards, such as ISO 306 and ASTM D1525. It provides accurate and reliable results, allowing manufacturers to assess the suitability of materials for various applications and ensure product quality.
