Polycarbonate Injection Molding Parts Processed at J&L
Polycarbonate – Robust and Versatile
Polycarbonate is an amorphous engineering thermoplastic with a high level of mechanical, optical, electrical and thermal properties. It offers outstanding mechanical, clarity, electrical and thermal properties. PC allows for design versatility. Different options include scratch resistance, toughness, heat resistance, weatherability, biocompatibility and compliance with FDA and USP requirements. Additives allow PC to be flame retardant. J&L Plastic Molding will help you realize these benefits:
Excellent Mechanical Properties
Polycarbonate Injection Molding parts exhibit exceptional impact resistance. PC is ideal for parts subject to high-stress environments or impacts. Its strength and toughness ensure longevity and durability.
High Temperature Resistance
Polycarbonate withstands a range of high temperature without deformation or loss of mechanical properties.
Transparency and Clarity
Polycarbonate possesses excellent transparency. It is an excellent choice for applications requiring clarity and cosmetic appearance.
Dimensional Stability
Polycarbonate exhibits minimal shrinkage. Its shrink value is from 0.005” to 0.007”. It produces consistent parts with excellent dimensional stability. PC can hold tight tolerances and can be processed into intricate shapes with complex geometry.
Chemical Resistance
Polycarbonate demonstrates good resistance to many chemicals, including oils, greases, and various solvents.

Polycarbonate Grade Focus: LEXAN 920-701
LEXAN 920-701 is a flame-retardant black polycarbonate grade balancing toughness, heat resistance, and flammability performance. It offers a tensile strength of 8990 psi, a deflection temperature under load (66 psi) of 279°F, and UL 94 V-0 flame resistance (0.06 in).
From a design-for-manufacture standpoint, the LEXAN 920 family is a medium-flow polycarbonate with an MFR of 15. That flow rate helps it fill complex geometries while maintaining mechanical strength and tight dimensional tolerances.
LEXAN 920-701 Advantages by Industry
Electronics: LEXAN 920-701 is suited for electrical applications because it combines flame retardance, electrical insulation, and heat resistance. It’s a strong choice for enclosures, connectors, PCB-related housings, and power supply covers where UL 94 V-0 performance matters.
Industrial: LEXAN polycarbonate is valued for toughness, weatherability, and long-term dimensional stability. LEXAN 920-701 is a durable option for housings, fluid-handling components, covers, structural frames, cable-management parts, and safety guards where fire load and smoke performance are important.
Medical and Healthcare: LEXAN 920-701 supports demanding medical housings with high toughness, UL 94 V-0 flame performance, and good thermal stability. Its moderate flow makes it suitable for thin-wall housings, snap-fits, and precise features in patient monitors, diagnostics, and lab analyzers that must withstand repeated assembly, cleaning, and handling.
