"Iupital" Low Elastic Modulus/High Toughness Grade V20 series

Mitsubishi Engineering-Plastics Corporation

"Iupital" low elastic modulus/high toughness grades V20 series are new polyacetal grades of low elastic developed with the polymer modified technology. They also have high toughness with significantly improved breaking elongation.


* Low elastic modulus and high toughness even without compounding elastomer.
* Excellent surface impact and outstanding hinge characteristics.
* Less fricative sound. Good for noiseless gear.
* Good for extrusion molding due to slow crystallization.

Grade Line-up

V20-HE* Good wear resistance
V20-MT, V20-HT* Good wear resistance
* Excellent surface impact
* Great strain at break
* Excellent anti-static characteristic
