In some cases, it is desirable to increase the permeability of a polymeric material. One example is breathable films. For example, calcium carbonate filled PP films are first made by solvent casting, or extrusion casting or as blown film and subsequently stretched to delaminate the filler - polymer interface [57]. High filler loadings are used to ensure interconnecting voids, giving unimpeded diffusion [58]. [Pg.371]

The company has 1300 employees. Major products are PP resin, glass fibre-reinforced PP, calcium carbonate-filled PP and 1,4-butanediol. Its annual output of PP resins is 6400 tonnes. [Pg.118]

Most carpet consists of face fiber, usually nylon 66, nylon 6 or polypropylene (PP), with polypropylene backing fabrics and a calcium carbonate filled styrene/ butadiene rubber (SBR) latex binder. It is feasible to sort carpets by the type of face fiber, but it is difficult to separate the face fiber from the backing fabrics and latex adhesive. Therefore, the focus of this chapter is on inexpensive techniques to recycle post-consumer carpet without separating the face fibers from the backing fabrics. [Pg.203]

Wellman, Inc., of Johnsonville, SC, recycles nylon 6 and nylon 66 carpet, using a proprietary process and formulates the product into moldable engineered nylon resins, with both filled and unfilled grades. Product purity is about 98 percent, but the company is working on improving that by reducing levels of dirt, calcium carbonate, and PP. ... [Pg.740]

Finishing of the filler surfaces may also greatly affect the system viscosity. For mica-filled PP [31] and various thermoplastics filled with calcium carbonate [202, 261] it was shown that the relative viscosity of filled systems was lower than that of systems which contained equivalent quantitied of unfinished filler. Note that in contrast to viscosity in shear, the viscosity in stretching is higher for systems with treated filler [202]. [Pg.38]

If higher stiffness is required, short glass reinforcement can be added. The use of a coupling agent can dramatically improve the properties of glass filled PP. Other fillers for polypropylene inclnde calcium carbonate and talc, which can also improve the stiffness of... [Pg.98]

Selected unsaturated carboxylic acids are particularly useful as coupling agents for calcium carbonate-type fillers. They interact strongly with the basic surface of the carbonate, unlike silanes that only show a weak interaction. In addition, unlike simple saturated carboxylic acids, which just have a beneficial effect on impact strength, unsaturated carboxylic acids may increase tensile strength. Table 6.5 illustrates this effect in a 60% filled CaCOs/PP homopolymer system. This system is heavily stabilized with both hindered phenol and phosphite-type antioxidants, and a small amount of peroxide was therefore added. [Pg.124]
