MABS TORAY 990 X88
Toray MABS 990-X88 – ultra-high-flow, crystal-clear MABS (Methyl-methacrylate-ABS) that pairs PMMA-grade clarity with quick-cycle moulding and good chemical gloss retention – ideal for thin, intricate cosmetic parts, appliance windows and LED optics.
Sold by container only: 19.00 mt/container. Quantity = number of containers.
Key Benefits
| Feature | Why it matters |
|---|---|
| Very high flow – MFR ≈ 18 g/10 min (220 °C / 10 kg*) | Rapidly fills ≤0.4 mm walls and multi-cavity tools, cutting clamp force and cycle time. |
| Exceptional transparency (≈ 90 % transmittance, 3 mm) | Delivers “glass-look” clarity for premium jars, light guides and protective covers. |
| Tougher than acrylic – Notched Izod ≈ 170 J/m at 23 °C | Survives drop shocks; no brittle shatter like pure PMMA. |
| Chemical-gloss resistance | MMA matrix resists crazing from alcohol fragrances, hand-sanitisers and detergents. |
| Design freedom | Clear base accepts dyes, pearlescent masterbatch, laser etching and vacuum-plating without primer. |
*Nominal value from Toray literature for the 990-series “X-flow” grade.

4. Applications & Compliance
Typical Applications
-
Super-thin cosmetic caps, airless-pump components and perfume bottle collars.
-
Transparent blender lids, kettle windows and water reservoirs in premium appliances.
-
LED light pipes, diffuser lenses, illuminated logo badges.
-
Diagnostic cartridges, cuvettes and instrument covers (non-implant).
-
High-clarity toys, stationery, phone stands and display risers.
Compliance / Processing Notes
-
Rated UL 94 HB; halogen-free formulation.
-
Toray supplies RoHS (EU 2015/863) and REACH (SVHC) compliance statements; some lots offer ISO 10993 data on request.
-
Dry 75–80 °C for 2 h; barrel 220–250 °C; mould 40–60 °C for maximum clarity.
-
Limit colour masterbatch ≤ 3 % to preserve transparency; use low-shear screws for optical parts.
Toray MABS 990-X88 lets designers mould ultra-clear, thin-wall parts fast – and keep them tough, glossy and chemical-resistant in everyday use.
