General-purpose type

Polycarbonate is a polyester in which dihydric (or polyhydric) phenols are joined through carbonate linkages. The general-purpose type of polycarbonate is based on 2,2-bis(4 -hydroxybenzene)propane (bisphenol A) and has the general structure ... 

General-purpose type is a high pressure decorative laminate (HPDL) designed for both horizontal and vertical appHcations where appearance, durabiUty, resistance to stains, and resistance to heat up to 135°C (275°F) are requited. 

Post-forming type is an HPDL similar to the general-purpose type but is capable of being thermoformed under controlled temperature and pressure in accordance with the laminate manufacturer s recommendations.

In Japan, the production of polystyrene (PS) is fairly high for example, 115 00001 were produced in 1999, involving one of the four major general-purpose type resins. It has been reported that some kinds of styrene oligomers, which are by-products of polymerization, remained in PS products [1]. In the Wingspread statement announced by Colborn et al. in 1996, it was reported that certain synthetic chemicals have endocrine-disrupting effects on humans or animals. Most of these chemicals are pesticides, but styrene dimers (SDs) and trimers (STs) are listed in this statement along with plasticizers and antioxidants [2]. 

SEQ 100 is the most widely used general purpose type chelating agent. It chelates calcium, magnesium and most other common metals throughout the pH range. It chelates iron from pH 2-11. ... 

Looking at Table 8.8 we can see that Viton A is a general purpose type of material and is the most widely used. It is a copolymer of vinylidene fluoride (VF2)... 

The Colloid Chemistry of Silica included results for a study of the desorption kinetics of pyridine as it was removed from the surface of an amorphous, porous silica gel [30], Included in this chapter are data, results, and discussion regarding pyridine desorption experiments that have been carried out on two different silica surface types which were exposed to thermal pretreatment in the 200-400°C range. Pyridine interactions have been studied to achieve an enhanced understanding of the types, configuration, distribution and relative acidity and concentrations of silanol sites present. The research completed includes studies of a general-purpose, type A, porous silica gel, and a type B, low acidity, chromatographic grade silica. 

Synthetic rubbers are classified broadly into general-purpose types and special-purpose types. As their name implies, the general-purpose types are intended for applications such as the manufacture of tyres and general mechanical products which call for no properties other than satisfactory elastomeric...
