Gunze’s Engineering Plastics Business

Gunze manufactures and markets functional components used in photocopiers, printers, and other office equipment. These components have also been adopted for industrial manufacturing processes. Our thin-walled PFA tubes for fuser rollers/belts and transfer belts have brought innovation to the office automation market, enabling excellent quality image printing. Designed to satisfy a wide range of customer requirements, our high-quality functional components for industrial applications help maintain the quality of products with stain-resistant properties. Even with components that work behind the scenes, Gunze’s engineering plastics provide a “feeling of comfort.”

Photocopier

1. PFA Tubes for Fuser Rollers/Belts
These tubes protect roller and belt surfaces from heat and stain by leveraging the unique properties of fluoro resin.
2. Transfer Belt
This photocopier component collects four color toners and transfers them onto paper. Our transfer belt features uniform quality, surface smoothness, and improved stability in electrical resistance.

Small-diameter Fluoro Resin Heat-shrinkable Tube

Small-diameter Fluoro Resin Heat-shrinkable Tube

This is a new product with a smaller diameter and a higher shrinkage rate compared to our conventional heat-shrinkable tubes. Another type with added tearability is also available.
