Novalloy B is PBT/ABS polymer alloy. Heat resistance, chemical resistance, and rigidity of PBT and processability of ABS are balanced.
Filler reinforced grades have DTUL higher than 200 ’C, it is possible to replace PBT/PET in electronic parts and working parts.
 General purpose grades |
 Chemical resistant and low friction and wear
Used in vending machine parts.
Filler reinforced grades |
Used for chassis and carriage of printers, due to high rigidity, heat resistance, and chemical resistance.
Used in frame of loudspeakers, with reason of adhesion performance.
Filler reinforced and flame retardant grades |
Used for connector of home video game machine, MPU cooling fan, and toner parts in LBP/PPC.

*“CELPURGE MA2” is recommendable for purging of Novalloy B.
For purging of filled grades or carbonized contamination, “CELPURGE AW2 / high cleaning type” or “CELPURGE AG4 / super cleaning type” is especially recommendable. |
