Injection Molding of Plastics from Agricultural Materials

OBJECTIVE DOE Chicago Operations %ice The objective of this research was to conduct a systematic study to relate injection molding parameters to properties of blends of starch and synthetic polymer. Blends of normal (25 % amylose) and high amylose (50 and 70% amylose) corn starch (containing between 60 and 70 % of the mixture by weight) and synthetic polymer were used in this research. Two diff...

Building better plastics with supercritical carbon dioxide

Nanocomposite plastics are a promising class of materials with a range of applications, particularly in the automotive industry. By incorporating mineral material of nanoscale dimensions, the mechanical properties of the bulk plastic, such as strength, thermal stability, and flame retardance, are drastically improved, with little to no impact on other favorable properties such as low weight. In...

Determining the Right Molding Process for Part Design How RIM Molding Advantages Compare with Traditional Production Technologies

Polyurethane Foam Molding Technologies for Improving Total Passenger Compartment Comfort

Improvements in passenger compartment comfort continue to be one of the key needs of the global transportation industry. Since their introduction more than 40 years ago, flexible molded polyurethane foams have successfully contributed to the comfort provided by all forms of transportation seating. Initially required to provide just a wide range of load bearing, seating foams are now being desig...

Environmental Hysteresis in Molding Compounds and Voltage Reference Microcircuits Encapsulated in Plastics

Hygroscopic swelling characteristics of different types of molding comp ounds and electrical parameters of voltage reference microcircuits encapsulated in plastics were measured after saturation with moisture at 85 C and humidity varying from 20% to 90% RH. Sorption of moisture at high humidity conditions and desorption during baking resulted in deformation of molding compounds of approximately...
