Polypropylene/polyurethane

Commonly used materials for cable insulation are poly(vinyl chloride) (PVC) compounds, polyamides, polyethylenes, polypropylenes, polyurethanes, and fluoropolymers. PVC compounds possess high dielectric and mechanical strength, flexibiUty, and resistance to flame, water, and abrasion. Polyethylene and polypropylene are used for high speed appHcations that require a low dielectric constant and low loss tangent. At low temperatures, these materials are stiff but bendable without breaking. They are also resistant to moisture, chemical attack, heat, and abrasion. Table 14 gives the mechanical and electrical properties of materials used for cable insulation. [Pg.534]

Later (1935—45), new materials such as silicone were developed as water repellent and heat resistant paint. The development of epoxy resins offered a structural material for boat and car bodies. Poly(tetrafluoroethylene) (PTFE), polycarbonate, poly(ethylene terephthalate) (PET), polypropylene, polyurethane, ABS and acetals are the latest additions to find their way into plastics technology. Studies have also been carried out with the use of fillers and plasticisers as part of the next generation of materials. [Pg.108]

Chapter 5 summarizes the investigation of lignocellulosic flax fiber-based reinforcement requirements to obtain structural and complex shape polymer composites. This chapter discusses in detail the possibility of forming complex shape structural composites which are highly desirable for advanced applications. Chapter 7 focuses on the structure and properties of cellulose-based starch polymer composites, while Chapter 8 focuses on the spectroscopic analysis of rice husk and wheat gluten husk-based polymer composites using computational chemistry. Chapter 9 summarizes the processing, characterization and properties of oil palm fiber-reinforced polymer composites. In this chapter, the use of oil palm as reinforcement in different polymer matrices such as natural rubber, polypropylene, polyurethane, polyvinyl chloride, polyester, phenol formaldehyde, polystyrene, epoxy and LLDPE is discussed. Chapter 10 also focuses on... [Pg.9]

The constituent polypropylene layers in all the commercially prepared polypropylene-polyurethane laminates were PP-F films. The single polyurethane layer in the PP-U-PP(B) and PP-U-PP(C) laminates contained a blue dye, as did the two polyurethane layers in the 3PP-2U(A) laminate. The two polyurethane layers in the 3PP-2U(B) laminate contained a violet dye. [Pg.88]

The general-purpose thermoplastic polymers consist of such materials as polyethylene, polypropylene, polyurethanes, and polyvinyl chlorides. The engineering thermoplastic polymers include the polyimides, polyamideim-ide, polysulfones, polyetheretherketones, and polyphenylene sulfides. [Pg.120]

Starch-based plastics can be classified as compostable if the additives are also biodegradable under industrial compost environment conditions. Starch can be an additive for petroleum-based plastics like polyethylene, polypropylene, polyurethane, and polyester. However, these starch-filled petroleum-based plastics are not included in this book since they would not biodegrade under industrial composting conditions and would not be recyclable with commercial mechanical recycling operations. [Pg.89]

Some of the harder materials are the ABS s, SAN s, nylons, polycarbonates, modified PPO, and polyether sulfones. The softest materials are the polypropylenes, polyurethanes, and fluoro-polymers. [Pg.60]
