Although polymer alloys/blends may not have reached the potential envisioned when first introduced over 30 years ago, they still constitute a significant market and exceed the growth rate of the GDP. Led by polycarbonate- and polyphenylene oxide (PPO)-based resins, alloys/blends have made sizable penetrations in automotive and electric/electronic markets. New variants (such as PVC- and polypropylene-based alloys/blends) are constantly being introduced into the marketplace. BCC's report provides a detailed quantitative analysis of this market for 1999 and 2004, highlighting applications, new developments and products, producers/suppliers, trade named products, and market estimates and forecasts of alloy/blend competitive products by application.
