Engineering Plastic

Polycarbonate (PC) Resin

Polycarbonate combines impact strength, heat resistance and transparency in suitable grades. Processing, drying and stress control are important for finished-part quality.

Typical Applications

Transparent Components

Covers, lenses and guards requiring impact and optical performance.

Lighting Products

Lenses and housings selected for heat, UV and optical requirements.

Electrical Housings

Parts requiring impact, heat and potentially flame-retardant performance.

Technical Moldings

Structural and functional components requiring dimensional and mechanical performance.

Grade Selection Factors

The following factors are application references, not guaranteed specifications. Final selection must be confirmed using the current producer TDS, COA and customer requirements.

Selection ItemWhat to Confirm
Flow Match part thickness, flow length and gate design.
Optical requirement Define clarity, haze, tint and surface quality.
UV and weathering Confirm indoor or outdoor use and exposure duration.
Flame rating State required rating and test thickness.

Information Needed for Quotation

Current grade, transparent or opaque use, process, wall thickness, optical target, UV, flame rating, color, quantity and destination port.

Frequently Asked Questions

Does all PC resin have the same transparency?

No. Optical quality, color and additive packages vary.

Can PC be used outdoors?

Use an appropriate UV-stabilized grade and confirm weathering requirements.

Why is drying important?

Moisture can cause degradation and appearance defects during processing.
