    CR-39, ama allyl diglycol carbonate (ADC), waa polymer caag ah oo caadi ahaan loo isticmaalo soo saarista muraayadaha muraayadaha indhaha.
    Soo gaabinta waxay u taagan tahay "Columbia Resin #39", kaas oo ahaa qaacidada 39-aad ee balaastiig heerkulbeeg ah oo uu sameeyay mashruuca Columbia Resins 1940kii.
    Waxaa iska leh PPG, maaddadan ayaa wax ka beddelaysa samaynta muraayadaha.
