Halogen Type

Butyl, and the halogenated butyls, can be cured by sulphur, dioxime and resin cure systems. In addition, the halogenated types can be crosslinked with zinc oxide, and diamines. Peroxides cannot be used because they tend to depolymerise the polyisobutylene. 

The prints exhibit excellent application properties. They are, for instance, entirely fast to organic solvents, soap, alkali, and acids. They are also fast to sterilization. Metal deco prints demonstrate very good heat stability. The products withstand exposure to 200°C for 10 minutes or to 180°C for 30 minutes. Although not quite as fast to heat as halogenated types of Copper Phthalocyanine Green, P.B.15 3 is thus somewhat more heat stable than stabilized a-Copper Phthalocyanine Blue.

Yields of alcohols vary from 45 to 87%, irrespective of solvent or halogen type. However, when crotyl halides are used, 1-methylallyl products are isolated [20], along with occasional diaddition products [Eq. (2)]. 

Inert material by itself Must be used with halogen-type compound. Used in all polymers where halogen compounds are the selected flame-retardant system. As a synergist, enhances efficiency. 

The spot heating lamp was a custom-built, MR 16, quartz-halogen type (General Electric EXS with a focal length of 4 cm and a smooth, aluminized reflector) operating at filament temperature around 3000°C. At the focal plane, the spot heater delivered a flux density in excess of 140 W/cm. At these temperatures, the maximum output occurred at a wavelength around 0.89 pm. 

The mechanical properties of some PENs are shown in Table 8.2. PENs exhibit excellent mechanical and thermal characteristics. However, their crystallization rates are slow. This property prolongs molding cycles in the course of fabrication. In contrast, some halogenated types do not suffer from this drawback.
