The more common mane is called Engineering Plastic. It has a high tensile strength and many other advantages. Not suitable for printing、water-dying、coating or plating(The POM material can be identified by simple burning process. It will not exhibit flames but has an agitated smell. Injection forming temperature at 180-230℃)
Nylon，also known as polyamide，has good forming characteristics，with high temperature and impact resistance.Available for screen printing、water-dying、coating and plating. However, use must be advised that the color fastness for lighter lone color in nylon is unstable. Nylon exhibits bubbles and fragrance when burning.
A very economical plastic material, the hardness is between POM and PE. PP displays a similar characteristic with PE. Finished texture for PP parts has no luster and there is no smoke exhibited when burning.
The most general type of plastic. Softer than POM and not suitable for low temperature environment or extended exposed to sun. PP has a greasy and oily surface finishes.
The highest forming temperature plastic material(280℃). Also the highest cost material. PC can be apply in application requires printing. It has a good transparent color quality and is not easily combustible.
The softest plastic material with good elasticity melting at 160℃ the hardness is identified by percentage; the higher percentage means softer texture. Has flame and foul smell when burning.
ABS(acrylontrile butadiene styrene)
A low cost plastic material that is compatible for plating. It is light and fragile with poor tensile strength. Not suitable for high or low temperature part application. Exhibiting both flame and fragrance when burning.
Have good transparent characteristics, lightweight but hard. Reflective to lights and can easily change color and shape. Less expensive than PC. Forming temperature at 180-220℃. Has flame but no smoke when burning.
Low cost synthetic rubber forming temperature between 180-190℃ has no black smoke when burning.
TPR(thermo plastic rubber)
Soft and good elastic character non-toxic but but high cost. The hardness is classified by percentage. The high percentage represents softer texture.
PU is softer than PE but harder than PVC. It is widely used in application requiring printing. Only recommend for using in parts and applications that requires tensile strength.柔軟度較PE軟、較PVC硬，可做印刷處理，但不
