5.2.2 Plastic

Designers should note that the following studies.

a) material category Plastic material parts, reduce the choice of thermosetting plastics, increased use of thermoplastics.

b) a flame retardant Preferred not contain a halogen element, bromine-based flame retardant plastic elements, such as the choice of Al (OH) 3, Sb2O3, phosphate, Mg (OH) 2. Wherein Al (OH) 3 both inorganic filler and a flame retardant effect, more extensive use.
