POLYCARBONATE MANIFOLDS

• 10-20% more costly than acrylic
• Highly impact resistant
• High clarity
• Continuous service temperature to 225°F
• Better chemical resistance; good for alcohols
• Available as a USP Class VI material
• Gray or purple tint typical
• Scratches easily

Polycarbonate has many possible configurations as a multi-layer laminated manifold with .020 or smaller channels (depending on the application). From a design standpoint, many discourage using square channels within manifolds here. Polycarbonate manifolds should have either D-shaped or full round channels for optimal flow. Channel spacing as close as 1x nearest feature size is possible. What's more, we can place flat bottom ½-28 ports or similar can on the bond line with surface finishes for valve mounting can hold as low as 20 µin.

When bonded, engineers can expect a very clear polycarbonate manifold (with a light gray or purplish tint, if using tinted stock). For frequent assembly and disassembly of pumps or valves, consider heat-staked threaded inserts over direct machined threads or helicoils. This is becuase polycarbonate is stress sensitive to long-term loading in stress risers. The pullout strength and low stress on other adjoining components make inserts a best-practice choice for polycarbonate manifold design.

Easy To Work With

This thermoplastic is easy to machine, polish, weld, and bond.

Elastic But Strong

Polycarbonate manifolds offer high modules of elasticity without compromising their strength or structure.

Electrical Capabilities

Excellent electrical properties and low moisture absorption extend its viability into electronic applications.

Diverse Use Cases

Many industries use PC regularly, including medical, diagnostics, and research.

High Impact Resistance

This plastic can take a punch and keep going. We can reinforce PC with glass for extra rigidity and strength.

High Clarity

With a slight blue or purple tint, we can polish PC to have a transparent finish.

Polycarbonate has the capacity to transmit 88% of light, making it ideal for windows and other products. Light transmittal, along with its superior impact resistance and toughness, makes polycarbonate an excellent choice for sight glasses, other optical uses, and housing parts. It is highly utilized in aircraft, fluid handling, electronic manufacturing, and the automotive industries.
