Processing technique

Prior to processing, it is necessary for the PVC and formulation additives to be combined intimately together in some form of mixer. The main converting processes are  [Pg.8]

This section will summarise the processing techniques applied in the manufacture of composite parts from LR and HTV silicone rubber. [Pg.303]

Commodity PE can be processed by various methods, which rank in importance and increasing [Pg.140]

In general, the design of extrusion dies is complicated by the phenomenon of die swell, which is very pronounced for most polymeric materials. Die swell, which may involve a two- or three-fold increase in cross-sectional dimensions, depends on resin characteristics as well as on flow conditions. For simple geometries, drawdown can be used to correct the dimensions, but this is not generally sufficient for complex shapes such as those encountered in profiles. [Pg.141]

Extrusion outputs are sometimes limited by flow instabilities producing rough surfaces (shark skin) or periodic fluctuation, but the cooling of thick extrudates is often the major limiting factor because of the low thermal conductivity of PE. [Pg.141]

Practically all PE grades can be processed by extrusion, but in order for the emerging extrudates to maintain their shape until they solidify, extrusion grades tend to have relatively high molecular weights associated with high viscosity and melt strength. Very viscous UHMWPE is often processed by screwless (ram) extrusion. [Pg.141]

Melt temperatures for extrusion of HDPE are 200-300 C and for LDPE are 180-240 C. Higher melt temperatures are needed for extrusion coating (280-310 C). A three-zone screw with a length- [Pg.141]

Mean-centering, as is shown by experience, can be successfully employed in combination with another data pre-processing technique, namely scaling, which is discussed later. [Pg.213]

Different resins have been developed for use in different reduction—ratio appHcation ranges (111,112). The powders suitable for high reduction—ratio appHcations, such as wire coatings, are not necessarily suitable for the medium reduction—ratio appHcations, such as tubings, or the low reduction—ratio appHcations, such as thread-sealant tapes or pipe liners. AppHcations and processing techniques are being used, which utilize the unique combination of properties offered by PTFE in fine powder form (113—115). [Pg.354]

Standard thermoplastic processing techniques can be used to fabricate FEP. Thermal degradation must be avoided, and a homogeneous stmcture and good surface quaUty must be maintained. [Pg.361]

Various processes can be used to produce energy or gaseous, liquid, and solid fuels from biomass and wastes. In addition, chemicals can be produced by a wide range of processing techniques. The following Hst summarizes the principal feed, process, and product variables considered in developing a synfuel-from-biomass process. [Pg.15]

Thus, CIS is a promising photovoltaic material, but improved processing techniques are needed to achieve commercial production of advanced high efficiency CIS alloy materials. Table 1 summarizes the laboratory and commercial status of significant PV technology. [Pg.473]

Thermoplastics. The highest consumption of color concentrates is in thermoplastic resins, such as low and high density polyethylene, polypropylene, PVC, and polystyrene. Processing techniques for thermoplastics are usually based on dry color dispersion in a compatible resin (36). [Pg.515]

Emissions During Processing. During the production of flexible PVC products plasticizers are exposed for up to several minutes to temperatures of - ISO C. The exact conditions depend on the processing technique employed, but it is evident that the loss of plasticizer by evaporation and degradation can be significant. [Pg.131]

Of the various processing techniques used, injection mol ding and extmsion involve Htfle or no exposure of hot product to the surrounding air, hence they give rise to no significant emission of plasticizer to the atmosphere. This is not the case in the production of sheet and film by calendering or spread coating. [Pg.131]

High Alumina. The naturally occurring raw materials are bauxites, sillimanite [12141 5-6] group minerals, and diaspore clays (see Aluminum compounds). Other high alumina raw materials are made by beneficiation, blending, and other processing techniques. [Pg.25]
