The main plastic wire materials for brushes are: nylon wire, PBT wire, PP wire and PET wire, nylon wire is undoubtedly one of the best overall performance materials, wear-resistant, heat-resistant, good resilience, toughness, but the cost is relatively high, the unit price of dozens to hundreds of yuan / kg, PBT wire performance is closer to nylon wire, water absorption is relatively low, good acid and alkali resistance, good resilience, the cost is lower than Nylon wire, PP wire and Το PET έχει υψηλότερη σκληρότητα, καλή καθαριστική ισχύ, μπορεί να αναπηδήσει γρήγορα μετά την κάμψη, ανθεκτικό στην όξινη και αλκαλική διάβρωση και χαμηλότερο κόστος.
