Dear All,

    How to check the PVC granule density & XLPE granule density? which liquid solution should i use ?kindly let me know the step by step procedure.

easy by water.....pvc with density > 1 will be under water and pe with density < 1 will swim on water...by mixing water woth alcohol you can match densites accurately....Dr. Günter Beyer

calculate PVC weight and put 100 ml water after again calculate valume .

variation between gives us to volume and divide weight to volume
