General Description: PHB and its copolymers with polyhydroxyvalerate (PHV) are melt-processable semi-crystalline thermoplastics made by biological fermentation from renewable carbohydrate feedstocks. A common name for many synthetic polymer materials is plastic, which comes from the Greek word "plastikos", suitable for molding or shaping. It is biodegradable, nontoxic, biocompatible plastic produced naturally by bacteria and a good alternative for many non-biodegradable synthetic polymers. This biocomposite consists of two matrixes: 1.) When polymers are found in living systems, they are referred to as biopolymers. There are three types of classification under this category, namely, Natural, Synthetic, and Semi-synthetic Polymers. Figure 1 (from Chemistry in Context) shows a single monomer, and a polymer made of identical monomers linked together. Polymers are not always man-made - they occur naturally and are made by all living organisms. Helian Polymers offers two of such types, a PHB (Polyhydroxybutyrate) and a PHBV (Poly(3-hydroxybutyrate-co-3-hydroxyvalerate). Since the beginning of the 20th century, hundreds of polymers have been synthesized. Pure chitin is translucent and flexible. Polyethylene is considered to be as one of the simplest polymer, it has ethene or ethylene as the monomer unit whereas the linear polymer is known as the high density polyethylene-HDPE.
