CYCOLOY C2950 is a polycarbonate/ABS blend (PC/ABS), non-chlorinated, non-brominated flame retardant, high heat, from NexPoint Materials (formerly SABIC). The data sheet lists melt flow rate (260 °C / 2.16 kg) as 10 g/10 min (ASTM D1238). Density: Specific gravity 1.18 (about 0.0426 lb/in³). Grades from other producers to ask about include Bayblend FR3010 and WONDERLOY PC-540. They are not identical, so compare the data sheets and run a trial before switching.

CYCOLOY C2950 specs from the data sheet
Typical values from the producer’s published data sheet (CYCOLOY FR Resins C2950 (Americas technical data sheet, revision 20260305). This is the standard C2950, not C2950HF.). Typical values are not specifications; the lot COA shows what you actually receive. Values only compare at the same test method and condition.

Grades to ask about instead of CYCOLOY C2950
These grades from other producers have similar published specs. None is a drop-in replacement: additive packages, flow at molding shear rates, color and approvals differ. If your part, drawing or customer approval names CYCOLOY C2950, any change needs your approval and usually a trial.
| Grade | Producer | Melt flow | Density | Key property | How it compares |
|---|---|---|---|---|---|
| Bayblend FR3010 | Covestro | MVR 15 cm³/10 min (240 °C / 5 kg, ISO 1133) | 1.18 g/cm³ (1,180 kg/m³, ISO 1183-1) | UL 94 V-0 at 1.5 mm, 5VB at 2.0 mm, 5VA at 3.0 mm; Vicat B120 110 °C | Flame-retardant PC/ABS with V-0 at a similar thickness, but flow is measured at a different condition (240 °C / 5 kg) and all data is ISO, while C2950 data is ASTM. Different producer and UL file. Not a drop-in replacement; check the UL card at your thickness. |
| WONDERLOY PC-540 | CHIMEI | MFR 21 g/10 min (260 °C / 2.16 kg, ASTM D1238) | 1.18 (ASTM D792) | UL 94 V-0 at 1.5 mm and 5VB at 2.0 mm (ISO sheet adds 5VA at 2.5 mm); notched Izod 52 kg-cm/cm (9.52 ft-lb/in) at 3.2 mm | Same flow test condition, but PC-540 flows about twice as easily (21 vs 10 g/10 min), which can change fill and pack settings. Heat deflection is lower: the ASTM sheet gives 82 °C unannealed without stating the load, and the ISO sheet gives 83 °C at 1.8 MPa, against 90 °C for C2950 at 1.82 MPa and 3.2 mm. Different producer and UL file; the sheets we found were hosted by a distributor. Not a drop-in replacement. |

Typical uses for CYCOLOY C2950
The data sheet calls CYCOLOY C2950 a standard high heat PC/ABS grade for injection molding and an excellent candidate for a wide variety of applications including appliances, lighting and electrical.
What to check before you switch
- Pull the UL yellow card and confirm V-0 and 5V ratings at your wall thickness and color.
- Check agency, customer and end-use approvals; flame-retardant changes often need requalification.
- Dry to the producer's moisture limit; PC/ABS is sensitive to moisture.
- Confirm color match and availability for the new grade.
- Run a trial and check flow, part fit and heat performance before switching.
Buying CYCOLOY C2950 or an equivalent
Send us the grade name, your annual volume and ship-to location. A polymer chemist checks the data sheet and we quote CYCOLOY C2950 where we can source it, or a qualified equivalent, saying clearly which one you would get. Orders start at one gaylord. For background on this resin family see PC/ABS grades and buying guide; for several grades at once, use the resin RFQ template.

What is CYCOLOY C2950?
CYCOLOY C2950 is a flame-retardant PC/ABS blend that uses a non-chlorinated, non-brominated flame retardant. It is a standard high heat grade for injection molding. The CYCOLOY brand is now owned in the Americas and Europe by NexPoint Materials, the former SABIC engineering thermoplastics business.
What is the melt flow of CYCOLOY C2950?
The Americas data sheet lists a melt flow rate of 10 g/10 min at 260 °C with a 2.16 kg load (ASTM D1238).
What is equivalent to CYCOLOY C2950?
Flame-retardant PC/ABS grades with similar published ratings include Covestro Bayblend FR3010 and CHIMEI WONDERLOY PC-540. Neither is a drop-in replacement: flow, heat and UL files differ, so check each sheet and UL card at your thickness.
What is the UL 94 rating of CYCOLOY C2950, and is it food contact approved?
The data sheet lists UL 94 V-0 at 1.49 mm and 5VB at 2.48 mm, UL yellow card E121562-221034. The data sheet does not state food contact compliance.
Can ResinBridge quote CYCOLOY C2950?
Yes. Send the grade name and volume. A polymer chemist checks it and we quote the grade where we can source it, or a qualified equivalent, and say which. Orders start at one gaylord; U.S. and Canada only.
Need CYCOLOY C2950 or an equivalent?
A polymer chemist reviews every request, then matches your grade or finds a qualified equivalent and prices it.
