Electrical Injection Molding Materials
PP
PP is a budget-friendly plastic that is highly resistant to chemicals and is very flexible, which makes it suitable for low-stress electronics applications. It is widely used to produce electronic housings, battery clips, and connectors, and is frequently used in consumer electronics where light-weight components are needed.
- Mill Lead Time: Up to 4 days
- Color: Natural, White
ABS
ABS (Acrylonitrile Butadiene Styrene) is a thermoplastic polymer used for general purposes that is produced by emulsion. Its high chemical resistance of corrosive chemicals makes it find broad usage in automotive parts, toys, and electronics enclosures.
ABS is a simple material to machine and has a relatively low melting point, making it easily moldable and deformable. Its excellent impact resistance also makes it suitable for use in products exposed to high stress or force. Such special properties also ensure the popularity of ABS in many industries globally.
Common applications: Enclosures
PC
PC possesses favorable strength, transparency, and shock resistance and thus is used on electronic components requiring strength and transparency. Applied to LED light covers, electronic display screens, and cover cases of electronic products like smartphone and tablets.
