POLYLAC PA-757 is a acrylonitrile butadiene styrene (ABS), general purpose, high gloss, medium impact, from CHIMEI. The data sheet lists melt flow index (200 °C / 5 kg) as 1.6 g/10 min (ASTM D1238). Density: 1.05 g/cm³ (0.0379 lb/in³). Grades from other producers to ask about include CYCOLAC MG47 and Terluran GP-22. They are not identical, so compare the data sheets and run a trial before switching.

POLYLAC PA-757 specs from the data sheet
Typical values from the producer’s published data sheet (PA-757 (general ABS). Values are from CHIMEI's ASTM data sheet dated September 20, 2023, with ISO values from the ISO sheet dated January 21, 2025.). 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 POLYLAC PA-757
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 POLYLAC PA-757, any change needs your approval and usually a trial.
| Grade | Producer | Melt flow | Density | Key property | How it compares |
|---|---|---|---|---|---|
| CYCOLAC MG47 | NexPoint Materials (formerly SABIC) | MFR 5.6 g/10 min (230 °C / 3.8 kg, ASTM D1238); MFR 18 g/10 min (220 °C / 10 kg, ISO 1133) | 1.04 g/cm³ (specific gravity 1.04, ASTM D792) | Notched Izod 320 J/m at 23 °C (ASTM D256); HDT 80 °C at 1.82 MPa, 3.2 mm, unannealed; UL 94 HB at 1.5 mm | Multi-purpose injection molding ABS from the Americas with a similar ISO flow at 220 °C / 10 kg. Its notched Izod is higher than PA-757, and the ASTM flow is measured at a different condition (230 °C / 3.8 kg), so the ASTM flow numbers cannot be compared directly. Not a drop-in replacement; compare gloss and color on molded parts. |
| Terluran GP-22 | INEOS Styrolution | MFR 1.5 g/10 min (200 °C / 5 kg) and 19 g/10 min (220 °C / 10 kg), ASTM D1238 (Americas data) | 1.04 g/cm³ (ASTM D792) | Notched Izod 5.6 ft-lb/in (about 300 J/m) at 23 °C; DTUL 172 °F (about 78 °C) at 264 psi, unannealed | Very close flow to PA-757 at 200 °C / 5 kg. Impact is higher and heat deflection is lower than PA-757 on paper. INEOS Styrolution does not list a UL 94 rating on this page, so check the UL file if you need HB. Not a drop-in replacement. |

Typical uses for POLYLAC PA-757
CHIMEI lists home appliance, office appliance and electronic product casings, copier casings, telephone casings and boxes for cosmetics.
What to check before you switch
- If the part needs a UL 94 rating, pull the UL yellow card for the new grade at your thickness and color.
- Check customer and end-use approvals before changing resin source.
- Dry the resin as the producer recommends; ABS picks up moisture and can show splay.
- Compare gloss and color on molded parts, since high gloss is a main reason this grade is chosen.
- Run a trial for fill, shrink and fit before switching production.
Buying POLYLAC PA-757 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 POLYLAC PA-757 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 ABS grades and buying guide; for several grades at once, use the resin RFQ template.
Trade names belong to their owners. ResinBridge is not affiliated with these producers; grade names are used only to identify the material. Data reflects published sheets as of October 2026.

Common questions
What is POLYLAC PA-757?
POLYLAC PA-757 is a general purpose ABS from CHIMEI, described as high gloss with medium impact strength, for injection molded housings and casings.
What is the melt flow of PA-757?
CHIMEI's ASTM sheet lists 1.6 g/10 min at 200 °C with a 5 kg load (ASTM D1238). The ISO sheet lists 19 ml/10 min at 220 °C with a 10 kg load (ISO 1133).
What is equivalent to PA-757?
General purpose ABS grades with similar published specs include CYCOLAC MG47 (NexPoint Materials, formerly SABIC) and INEOS Styrolution Terluran GP-22. Neither is a drop-in replacement: impact, heat deflection and gloss differ, so compare the sheets and mold trial parts.
What is the UL 94 rating of PA-757, and is it food contact approved?
The data sheet lists UL 94 HB at 1.5 mm. The data sheet does not state food contact compliance.
Can ResinBridge quote POLYLAC PA-757?
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 POLYLAC PA-757 or an equivalent?
A polymer chemist reviews every request, then matches your grade or finds a qualified equivalent and prices it.
What to send for an accurate quote
- The grade name, from any supplier, or a data sheet
- Color (natural, black or a custom match)
- Fill type and percentage, if any
- Melt flow, if you know it
- Quantity for this order and what you use in a year
- Ship-to city and state or province
