There are five major varieties of general plastic granules: PE, PP, PVC, PS and ABS.
According to the optical properties of plastics, can be divided into transparent, translucent and opaque materials, such as PS, AS, PC, etc. belong to the transparent plastic, while most other plastics are opaque plastic.
The current plastic pen with the most plastic for: ABS and AS
ABS characteristics: good rigidity, high impact strength, heat resistance, low temperature, corrosion resistance, easy processing, easy to paint, coloring, etc., but poor light transmission.
Applications: general opaque barrel and accessories, the surface needs to be painted and electroplated.
AS characteristics: high transparency, poor toughness
Application: Transparent parts
Other commonly used materials are PC, PP, etc.
PC, high impact strength, high transparency, good dimensional stability, but the price is more expensive, for some transparent parts with special requirements will be used
PP, non-toxic, tasteless, milky white highly crystalline polymer, is currently one of the lightest varieties of all plastics, relatively inexpensive, but low dimensional accuracy, rigidity, easy aging, brittle, easy deformation, poor dyeing, printability and adhesion.Especially for printing, it can only be firmly processed after special treatment.
