Plastic mold materials and their utilization technique.

Fiber reinforced plastic composites using recycled materials

This work investigates the feasibility of using recycled high density polyethylene (rHDPE), recycled polypropylene (rPP) and old newsprint fiber (ONP) to manufacture fiber reinforced composites. The boards were made through air-forming and hot press. The effects of the fiber loading and coupling agent content on tensile, flexural, internal bond properties and water absorption and thickness swel...

Plastic surgery: technique or discipline?

The definition of “plastic surgery” has been subject to a variety of interpretations. To the practitioner who has completed formal training in plastic surgery, it is defined and inherently recognized as a specialty that encompasses a vast body of knowledge and that requires a comprehension of fundamental principles and concepts that allows one to plan and execute a particular operation. In othe...

Colorant Materials, Additives in Plastic Technology

Pigments and dyes are coloring substances, i.e., substances imparting a specific color to the substrate being colored (Carolin et al. 2015). Pigments and dyes are distinctly different types of colorants. A pigment is a finely divided solid which is essentially insoluble in its polymeric application medium. Pigments are incorporated by a dispersion process into the polymer, while it is in a liqu...
