Vinyl chloride garden

Dibutyl phthalate is a plasticizer added to the poly(vinyl chloride) used in vinyl upholstery and garden hoses. Since plasticizers are more volatile than the high molecular weight polymers, they slowly evaporate with time, making the polymer brittle and easily cracked. Plasticizers like dibutyl phthalate that contain hydrolyzable functional groups are also slowly degraded by chemical reactions. 

A plasticizer can be added to a polymer to make it more flexible. A plasticizer is an organic compound that dissolves in the polymer, lowering the attractions between the polymer chains, which allows them to slide past one another. Dibutyl phthalate is a commonly used plasticizer. It is added to poly(vinyl chloride)— normally a brittle polymer— to make products such as vinyl raincoats, shower curtains, and garden hoses. 

Vinylidene Chloride-Vinyl Chloride VDC/VCM). VDCA CM copolymers are tough, flexible, and durable. As a film, they find significant use in the food packaging industry. They are also manufactured as a fiber used in car upholstery and garden furniture fabrics. 

Poly (vinyl chloride) (PVC), used in floor tiles, garden hoses, plumbing pipes, and trash bags, has a chlorine atom substituted for one of the hydrogen atoms in ethylene. 

Fluidized bed sintering is not really a type of sintering. Here, heated metal parts which have previously been roughed by sandblasting or treated with primers are dipped into a fluidized bed of the plastic powder. The plastic powder, with particle sizes of 200 yua melts on the warm surfaces and flows into a thick film of 200-400 /xm. In this way, for example, garden furniture can be coated with polyamides. Poly(ethylene), poly(vinyl chlorides), and polyamides are often processed in this way, as is, less frequently, cellulose acetobutyrate. 

Particulate-filled composites are widely used in many fields of application. The filler used in largest quantity is CaCOs, which is added mainly to poly(vinyl chloride), but significant amounts are used also in polypropylene, polyethylene and other polymers. Typical products prepared from CaCOs-filled composites are sewer and drainage pipes, garden furniture and breathable films [1]. The properties of particulate-filled polymers are determined by several factors, of which interfacial interactions are extremely important [2, 3]. Particle-particle and... 

For example, vinyl chloride is polymerized to form polyvinyl chloride (PVC), which is a very hard polymer used to make plumbing pipes. PVC can be softened if polymerization takes place in the presence of compounds called plasticizers, as we will explore in more detail in Chapter 27. PVC made with plasticizers is a bit more flexible (although durable and strong) and is used for a wide variety of purposes, such as garden hoses, plastic raincoats, and shower curtains. Table 11.3 shows a number of common polymers produced via a radical process. 

The main application of the vinylidene chloride — vinyl chloride copolymers is for filaments, which are made by melt extrusion and drawing. The filaments are used for such applications as car upholstery, garden chair fabrics and filter cloths where toughness, durability and chemical resistance are required. These copolymers are also used for packaging film, which is made by extrusion and biaxial stretching. The film has very good clarity, toughness and moisture and gas impermeability.

Poly(vinyl chloride) is used extensively in the construction industry (pipes, vinyl siding, window and door frames), for the insulation on electric cables. In clothing (such as in Goth and Punk fashion), for medical devices, and the manufacture of ordinary garden hoses.
