Blends of two or more thermoplastic polymers provide a combination of properties and price not found in a single polymer, copolymer, or reinforced plastic. Production is growing rapidly. In this report, SRI examines the technology of thermoplastics blends, particularly ways of preparing stable blends from components that are not always compatible.
This report focuses on blends of high-performance polymers with low-cost polymers, particularly injection-molding and extrusion grades of engineering thermoplastics. Properties and compositions of modified ABS resins, blends of ABS with other polymers, and polycarbonate blends are examined in detail. Tradeoffs in eight key properties for more than 100 commercial blends are displayed in a new graphical presentation.
The report also reviews equipment, procedures, and costs for producing blends on a commercial scale.
