Exablend® PC-900 — transparent injection molding polycarbonate UL 94 V-2

Description

Exablend® PC 900 is a transparent injection molding polycarbonate rated UL 94 V-2 from Material Wizard. A standard medium-flow injection grade of polycarbonate for precision thin-walled parts with high light transmission, impact strength and basic flame retardancy. The base formulation without UV stabilization is intended for indoor use. For outdoor applications, the UV-stabilized modification Exablend® PC 901 is available.

Exablend® PC series — how to choose a grade

• Exablend® PC 900 — base transparent V-2 for indoor use (this product card)
• Exablend® PC 901 — UV-stabilized transparent V-2 for outdoor use
• Exablend® PC GF 930 — glass-filled PC GF30 for structural parts with increased stiffness and dimensional stability
• Exablend® PC/ABS 965 — PC+ABS blend for parts with complex geometry and reduced water absorption

Advantages

• High impact strength over a wide temperature range (-40 … +120 °C) — characteristic of the PC class
• Light transmission of ~88 % with minimal haze — for optically clear housings and lenses
• V-2 out of the box without loss of transparency (a typical problem of FR additives in PC)
• Good flow for thin-walled housings of 1.0–1.5 mm
• Stable dimensions under humidity changes (water absorption 0.15 % vs 1.5–3 % for PA)
• Compatible with hard-coat coatings (Margard type, AR) for anti-scratch requirements
• Can be tinted in any transparent shades (transparent tinted) while retaining V-2

Limitations — honestly

• V-2, not V-0. V-0 requires dedicated FR grades with minimal change in transparency (made to order)
• Not for outdoor use in the base formulation — pure PC yellows under UV within 6–12 months. For outdoor use choose Exablend® PC 901 or third-party UV-coated solutions
• Sensitive to stress cracking in contact with aliphatic hydrocarbons, ketones, acetone and alkalis — incompatible with cleaning solvents
• The surface is scratch-sensitive — cosmetic applications require a hard coat (AR/MAR)
• Mandatory drying before processing: 120 °C, 3–4 h down to <0.02 % moisture — otherwise visible silver streaks appear on the surface
• High processing temperature (melt 280–310 °C) — hot-runner tooling is preferable
• Light transmission drops by 5–8 % after 1000 h of UV exposure — transparent outdoor applications require a stabilized grade

Target applications

Lighting: diffusers for household and office LED luminaires, housings of transparent decorative lamps, elements of flashlights and portable light sources.

Electronics: transparent housings of handheld devices, display windows (with hard coat), protective panels of instrument clusters, housings of USB devices and adapters.

Medical and laboratory equipment: equipment inspection windows, transparent protective screens, cuvettes and labware (USP Class VI compliance on request), elements of sterilizable housings.

Home appliances: transparent microwave doors / windows, baking equipment elements with visual monitoring, housings of blenders and food processors.

Industrial safety: protective machine guards (indoor), machine tool inspection windows, transparent conveyor guards.
