Sy was writing about ABS Plastic and its use in pianos..in a former life, I worked for a division of GE that makes Noryl Plastic, a competitor to ABS..FYI, Noryl Plastic is what is used on the exterior of the Saturn cars you see around town..i won't go into the chemistry, but the main ingredient is nylon, with rubber being a close second..this makes the end product very durable..also very hard to mass-produce, but we did it! Sy, i would be very interested to know what ABS product/products are used to mold piano parts..you would have to do some serious investigating, starting with the Kawai assembly process and work backwards from there. I believe ABS is a Poly-Styrene based product..Noryl is a Polyphenylene Oxide-based product, or PPO for short. ok..end of chemistry lesson, and an interesting topic at that. Phil
