Analogous also to TS SMCs and BMCs are TP molding compoimds in sheet form, known as glass mat thermoplastics (GMTs), and compoimded into standard granules for injection molding and extrusion. Most TPs are capable of combination with reinforcement. The main types used commercially are PA and PP. [Pg.214]

It is possible with solvents of a particular composition to determine quantitatively the level of stress existing in certain TP moldings where molded-in stresses exist. The stresses need not be applied ones but can be residual (internal) stresses resulting from the molding or other forming process that was used to shape the plastic part. Solvent mixtures suitable for this type of test are available for materials such as PSs, PCs, and acrylics through resin suppliers, who can provide details. [Pg.270]

During our tests we wanted to check by how much and how quickly TPS moldings could decompose in a natural environment Prepared test bars of molded potato starch, glycerol, and plant fibers (dry moisture contents of 4%) were placed in special baskets and stored in plastic boxes 15 cm underground, covered with garden soil of 70% humidity and pH 6.5 for 2,4,8 and 12 weeks. In order to assure stable soil humidity, the water loss indicated during the process was supplemented twice a week (Figures 12.5 and 12.6). [Pg.213]
