Advantages
Disadvantages
ABS
(ABS, butadiene, cinnamene styrene)
Intoxicity锛宻mellessness, low moisture absorption, ease to shape, ability to galvanize, spraying coating, stiffness, excellent rigidity, stable dimensions, low contraction and moderate price.
Low temperature of thermal deformation锛坮esistance to high temperature锕70鈩,resistance to low temperature -40鈩冿級,vulnerable to long duration exposure, depigmentation and fissuration, solubility in aldehyde, ketone, vinegar.
PC(polycarbonate)
Resistance to punch, excellent tenacity, high transparency, resistance to creeping, stable dimensions (little change with temperature, depth, environment), excellent self-extinguishing at the internal temperature up to 110鈩, low moisture absorption, excellent resistance to inflammation and electrical insulation.
Dishescence during high internal force, infusion moulding rate of PC is less than that of ABS锛圓BS is possible to be added.锛
PA(polyamide, nylon)
Wear-resistance, high tenacity, intoxicity, resistance to cold and corrosivity, low coefficient of friction, ease to shape, resistance to the temperature up to 180鈩.
High moisture absorption, poor stability of dimensions, necessity to improve by filling and enforcing.
Polyformaldehyde(POM)
High crystallinity, high rigidity, excellent resistance to punch creeping and fatigue; outstanding self-lubrication, and wear-resistance and resistance to chemical.
Relatively large volume contraction during transforming from melting to solid, poor thermal stability  when copolymerizing with formaldehyde, it is not appropriate to put the material long in the material chamber of the moulding machine, otherwise the decomposition will be caused, bubbling during melting, leading to yellowing and degrading mechanical strength.
Polyester
Fairly good tenacity, relatively high tensile-strength, ability to maintain physical and mechanical performance in a wide spectrum of temperatures, low coefficient of friction.
Ease to dissolve in oxidizing acids, poor stability of dimensions.
