Generally, thermoplastic pots are available in both crystalline and amorphous forms. The appearance of the crystalline plastic is translucent, opaque or opaque, and it is transparent only in the state of the film, and the hardness is soft to horny. Thermoset plastic pots usually contain a fill that is impervious to the material and is transparent if it is free of filler. The elastomer has a rubbery feel and a certain stretch ratio.
Different types of plastic pots have different densities. The density of the plastic pots can be identified by measuring the density, but the foamed products should be separated separately because the density of the foamed pots is not the true density of the materials. In the actual industry, the plastic pots are also sorted by the density of the plastic pots.
The combustion test identification method is to use a small fire to burn a plastic pot sample, observe the flammability of the plastic pot in the fire and outside, and pay attention to the method of identifying the type of the plastic pot after the flameout, the drop form and smell of the molten plastic pot. . Due to its low material cost and its self-flame retardant properties, it is also widely used in the construction industry, especially for sewer pipes, plastic steel doors and windows, plates, artificial leather and so on.
