Introducing Polyacetal Resin Copolymer Iupital

"Polyacetal Resin Copolymer Iupital®

High grade rigidity and flowability "A25-03"”   High grade rigidity and superior creep resistance "A10-03"


Mitsubishi Engineering-Plastics Corporation has newly developed "Iupital®A25-03" with high grade rigidity and flowability, and "Iupital®A10-03" with superior creep resistance.
 "Iupital A25-03®" has nearly 10% higher mechanical properties and excellent flowability when compared with conventional polyacetal resins.
 "Iupital®A10-03" has an improved variety of mechanical properties, and it also has superior creep resistance.
 Iupital®"A25-03" and "A10-03" can make conventional products thinner and lighter. They can be replaced with high-strength polyacetal resins such as homopolymers.
 Also, Iupital®"A25-03" and "A10-03" retain "excellent thermal stability", which is an advantage in polyacetal resin copolymers.
 Compared with various grades of polyacetal resin homopolymers, Iupital®"A25-03" and "A10-03" have relatively better heat stability; so they will be useful in improving working environments.
