A halin yanzu, yawancin masana'antun sarrafa kayan allura suna amfani da gaskeallurar bakeliteinjinan gyare-gyare da kumaalluran filastikinjinan gyare-gyare.Akwai bambance-bambance daban-daban tsakanin Dewei simintin bakelite injunan gyare-gyaren allura da injunan gyare-gyaren filastik.Bakelite shine PF (phenolic guduro).Bakelite wani nau'in filastik ne na masana'antu na farko, wanda ya sami ci gaban masana'antu a Amurka a cikin 1910. Bari mu ga menene bambanci?
Abubuwan da ake amfani da su don samar da bakelite sun fi phenols da aldehydes, kuma ana amfani da phenol da formaldehyde.Ana samun su ta hanyar polycondensation a ƙarƙashin catalysis na acid, alkali da sauran masu kara kuzari.Samar da masana'antu galibi ya haɗa da tsarin bushewa da tsarin rigar.
Phenol da aldehyde na iya samar da nau'ikan PF guda biyu a ƙarƙashin aikin masu haɓakawa daban-daban: ɗayan shine thermoplastic PF ɗayan kuma shine thermosetting PF.Na farko za a iya warkewa a cikin tsarin jiki kawai ta hanyar ƙara magunguna da dumama, yayin da na ƙarshe zai iya zama tsarin jiki muddin dumama ba tare da magani ba.
