Plastic Stone Testing Instruments

A plastic stone is made up of PVC and calcium carbonate to provide desired physical characteristics of both plastics and natural stones are disclosed. The plastic stone composite can be made of PVC having low molecular weight grade with K value less than 60, calcium carbonate powder characterized by particle sizes smaller than 400 mesh, and more than one additive. For example, the additives can include calcium zinc stabilizer, chlorinated polyethene, polyethene wax, stearic acid plasticizer, and acrylic processing aid. PVC's chemical stability decreases when the temperature increases and PVC has unstable physical properties related to heat and light. When exposed to more than 100° C. heat or directly under the sunlight for a long time, it will decompose, produce hydrogen chloride with automatic catalytic decomposition and cause discoloration and rapid deterioration of physical and mechanical functions/properties. Manufacturers can test the quality of plastic stone using various testing instruments such as Plastic Stone Testing Instruments.
