Common plastic variety identification method

Common plastic variety identification method

Before buying ultrasonic welding machine, we have to know what's the material we need to welding, so let's introduce you some way to identificate the plastic.

    Polypropylene PP is easy to melt and drip, less yellow smoke on the yellow, continue to burn oil

    Polyethylene PE is easy to melt and drip, and yellow and blue continue to burn paraffin burning smell

    PVC is difficult to soften, yellow, green, smoke, fire, extinguish, irritating sour

    POM POM is easy to melt and drip on yellow and blue, smokeless continues to burn and strongly stimulates formaldehyde

    Polystyrene PS is easy to soften foaming orange yellow, thick black smoke, charcoal continues to burn the surface oily bright special vinyl smell

    Nylon PA slowly melts and drops, foaming, slowly extinguishes special wool, nail odor

    Polymethyl methacrylate PMMA is easy to melt and foam, light blue, white, smokeless and continue to burn. Strong fruit and fruit odor, rotten vegetable flavor

    Polycarbonate PC is easy, soft foaming, a small amount of black smoke, extinguished from fire, no special taste

    Polytetrafluoroethylene PTFE does not burn. Decomposes a pungent smell of hydrogen fluoride in a fire.

    Polyethylene terephthalate PET is easy to soften and foam orange, with a small amount of black smoke slowly extinguishing the acidity from the fire

    Acryl-butadiene-styrene copolymer ABS slowly softens and burns without dripping yellow, black smoke continues to burn special smell

    Name English burning situation burning flame state odor after fire

    SAN: styrene-acrylonitrile used in cups, typewriter keys, refrigerator parts, oil filter cups and certain kitchen equipment;

    ABS: Acrylonitrile-butadiene-styrene used in the manufacture of automobile bodies, refrigerator doors, telephones, bottles, heels, machine casings, water pipes, building boards and ships, etc.

    PVC: Hard polyvinyl chloride is used to make caps and pipe tank linings;

    PTFE: Polytetrafluoroethylene is used in the electronics, chemical, and mechanical industries;

    PPO: Polyphenylene ether is applied to engineering plastics;

    PET: Polyethylene terephthalate, in addition to its very important role in the textile industry, can also be used in the manufacture of packaging films, audio tapes, soft drink bottles.
