New polyolefin sponge rollers for microelectronics
Article Type: New products From: Microelectronics International, Volume 29, Issue 2
Katsura in Japan have produced a new continuous micro-porous foam roller with excellent properties such as softness, resilience, water absorption and chemical resistance. Alternative base polymers of polyolefin or polyurethane are available so that the most suitable roller can be selected for diverse uses. For example, a polyolefin roller is recommended where chemical resistance is demanded, and a polyurethane roller is best for abrasion resistance (Tables I and II).
Squeegee rollers – Printed circuit board, lead frame, mini-lab, touch panel, semi-conductor, CoF tape, IC card/chip and, etc.
Washing pads – Hard disc, glass plate, medals, coins, etc.
Coating rollers – Ink rollers and miscellaneous coating.
Chemical squeeze rollers – Plating, etching, etc.
Polyurethane – Excellent water absorption; excellent abrasion resistance; excellent heat resistance; will not become hardened even when dried.
Polyolefin – Excellent chemical resistance; long life comparing with PVA sponge rollers; will not become hardened even when dried; suitable for soft etching, plating and aqueous flux coating processes.
