A precision Digital Density Apparatus based on the Archimedes Specific Gravity Method — a 220 g digital balance with 1 mg resolution and a density-determination kit (beaker, stand, sinker, thread) delivers accurate density measurement for plastic granules, polymers, rubber, foam and solid samples in under two minutes per test.
Density is one of the first checks a polymer lab runs on an incoming batch of plastic granules. It confirms the grade (HDPE 0.941–0.965 g/cc, LDPE 0.910–0.925, PP 0.890–0.910, PVC 1.38–1.42), flags contamination with foreign polymer, and detects filler or additive mix-up long before it reaches the extruder. For recycled plastics, density also verifies the composition of mixed-polymer streams.
The Digital Density Apparatus from International Equipments uses the Archimedes principle on a 220 g digital balance with 1 mg resolution. The density-determination kit — beaker, stand, sinker and thread — handles samples that float and samples that sink. One measurement takes under two minutes, giving a production QC lab the throughput needed for every incoming batch.
