Synthetic organic materials polyurethane

Natural or synthetic, mostly low-MW molecules that reduce or suppress microbe populations in plastics. Specialised products (both organic and inorganic) which tend to be used most in plasticised materials such as PVC and polyurethanes, as well as in rubber articles. The main cause of microbial growth is the additives themselves plasticisers, starch fillers, lubricants, thickening agents and oils. 

Water-based paints are dispersions based on synthetic polymers. Dispersions of polyacrylates are the most common. Examples of these paints include acrylic latex paint, heavy-bodied latex wall paint, latex enamel, latex primer, latex wall paint and sealing water-borne paint. Water-based paints can also contain water-soluble alkyd resin and a mixture of polyacrylate and polyurethane. Although water is the main solvent in these types of paints, comprising about 30-85% weight-to-weight ratio (w/w) of the raw materials, about 10% organic solvents are added to improve the film forming properties of the paint. (Hansen et al. 1987 van Faassen and Borm 1991 Wieslander et al. 1997). The differences between SBP and WBP can be seen in Table 2. 

Biomaterials [3] are defined as materials used within human bodies either as artificial organs, bone cements, dental cements, ligaments, pacemakers, or contact lenses. The human body consists of biological tissues (e.g., blood, cell, proteins, etc.) and they have the ability to reject materials which are incompatible either with the blood or with the tissues. For such applications, polymeric materials, which are derived from animals or plants, are natural candidates and some of these are cellulosics, chitin (or chitosan), dextran, agarose, and collagen. Among synthetic materials, polysiloxane, polyurethane, polymethyl methacry-...
