The short answer
Elastollan C 65 A HPM is a soft thermoplastic polyurethane (TPU) from BASF, based on a polyester polyol, in BASF’s aromatic HPM (high performance material) series. BASF’s range chart lists it as C 65 A 15 HPM with a measured hardness of 67 Shore A (DIN ISO 48-4, 3 s), density 1.18 g/cm³ (DIN EN ISO 1183-1-A), tensile strength 37 MPa and elongation at break 950% (DIN 53504-S2). BASF describes the HPM series as having very good damping and rebound, high temperature resistance, improved setting behavior and good demolding. Grades to ask about include BASF’s own Elastollan C 70 A 15 HPM, C 60 A 15 HPM and 565 A 12 P. They are not identical, so compare the data sheets and run a trial before switching.
Also written as: Elastollan C 65 A 15 HPM (full code in BASF’s range chart), Elastollan C65A HPM, BASF C 65 A HPM. In BASF’s naming, C means a polyester base, 65 A the nominal Shore A hardness, the 1 a cylindrical or lentil-shaped granule, the 5 an added lubricant, and HPM the high performance material series. Do not confuse it with Elastollan A C 65A 12 HPM, which BASF lists as an aliphatic polyester grade (color-fast, non-yellowing). Quote the full code from your drawing or bag label.

BASF’s test plaques for Elastollan are injection molded and tested at standard lab conditions; hardness, tear and compression set depend on dwell time, specimen type and conditioning, so compare them only at the same method.
Grades to ask about instead of Elastollan C 65 A HPM
These grades have similar published specs. All three are BASF aromatic polyester TPUs, so the polymer type matches. None is a drop-in replacement: hardness, additive packages, flow at processing shear rates, color and approvals differ. If your part, drawing or customer approval names Elastollan C 65 A HPM, any change needs your approval and usually a trial.
| Grade | Producer | Melt flow | Density | Key property | How it compares |
|---|---|---|---|---|---|
| Elastollan C 70 A 15 HPM | BASF | Not published in the range chart | 1.18 g/cm³ (DIN EN ISO 1183-1-A) | 71 Shore A (DIN ISO 48-4, 3 s); tensile 40 MPa, elongation 900% (DIN 53504-S2); tear 45 kN/m; abrasion 50 mm³; Vicat 90°C | Check. Same HPM polyester series, one step harder (71 vs. 67 Shore A measured). Slightly stronger, higher Vicat and lower compression set at 70°C (35% vs. 37%). Same density. A part designed around 65 A will feel stiffer. Quote this alternative › |
| Elastollan C 60 A 15 HPM | BASF | Not published in the range chart | 1.17 g/cm³ (DIN EN ISO 1183-1-A) | 63 Shore A (DIN ISO 48-4, 3 s); tensile 20 MPa, elongation 1,000% (DIN 53504-S2); abrasion 98 mm³; Vicat 70°C | Check. Same HPM polyester series, one step softer. Much lower tensile strength (20 vs. 37 MPa), almost twice the abrasion loss and a lower Vicat, so it suits softer parts with less wear. Quote this alternative › |
| Elastollan 565 A 12 P | BASF | Not published in the range chart | 1.22 g/cm³ (DIN EN ISO 1183-1-A) | 66 Shore A (DIN ISO 48-4, 3 s); tensile 30 MPa, elongation 850% (DIN 53504-S2); tear 65 kN/m; abrasion 55 mm³ | Partial match. Aromatic polyester TPU from BASF’s 500 series at a similar hardness, but not an HPM grade. BASF’s code P means it contains plasticizer, which can matter for migration, bonding and long-term hardness. Denser, so part weight changes. Quote this alternative › |

Typical uses for Elastollan C 65 A HPM
BASF’s range chart describes the HPM series as offering:
- Very good damping behavior and rebound
- High temperature resistance
- Improved setting behavior
- Good demolding properties
BASF’s range chart does not list specific end uses for C 65 A HPM. BASF does use it as the soft polyester example in its Elastollan material properties brochure (torsion modulus and damping, stress-strain at temperature, tear strength vs. temperature and thermal expansion curves), which is a useful reference if you are designing a soft damping or sealing part. For the TPU family in general, see our TPU buying guide.
What to check before you switch
- Hardness: the name says 65 A, but BASF’s chart gives 67 Shore A at a 3 s reading. Compare any alternative at the same scale, dwell time and specimen type.
- Aromatic vs. aliphatic: Elastollan A C 65A 12 HPM is a different, aliphatic polyester grade for color-fast, non-yellowing parts. Check which one your print calls for.
- Polyester vs. polyether: BASF lists hydrolysis resistance and resistance to microorganisms for its polyether (11 series) grades, not for the C series. C 65 A HPM kept 35 of 37 MPa tensile after 21 days in 80°C water in BASF’s test, but for long hot-water or humid service compare a polyether TPU. See TPE vs. TPU.
- Seals and buffers: compare compression set at the same temperature and time. C 65 A HPM is 25% at 23°C but 55% at 100°C. See seal compression set.
- Drying: TPU is hygroscopic. Dry to below 0.02% moisture; for HPM grades BASF gives 3–5 hours at 60–80°C in dehumidified air, not a circulating-air dryer. Dry any color masterbatch with the resin. See the resin drying guide.
- Plasticizer: 565 A 12 P contains plasticizer; C 65 A HPM is not marked P. Check bonding, paint and contact with other parts before switching.
- Availability: the range chart does not say where the grade is made or sold. Lead time is confirmed with your quote.
- Run a trial lot and check hardness, shrinkage, demolding and surface before you switch production.

Buying Elastollan C 65 A HPM: price, lead time and lot size
- Lot size. From one gaylord to a railcar. See gaylord, LTL and truckload for typical weights per box.
- Where it ships from. We have access to 100+ partner warehouse locations. Material already in a partner warehouse usually moves sooner than a grade that has to come from the producer; your quote says which applies.
- Price. We do not publish prices because they move with feedstock, freight and order size. What moves your price most: lot size, color, ship-to region, whether the grade has to come from overseas, and whether you need Elastollan C 65 A HPM itself or can accept a matched alternative. See how resin is priced and the monthly market update.
- Paperwork. Supplier COA on every prime lot (what a COA shows). Ask for BASF’s product information sheet and any regulatory statement your part needs.
- Trying an alternative? Start with one gaylord as a trial lot, molded and checked before you commit a full release. Samples (~50 lb) are available upon credit approval.
- If Elastollan C 65 A HPM itself is not available. Some branded grades are sold only through the producer’s own channels or go on allocation. If we cannot source it, we tell you, then quote a matched alternative with a side-by-side comparison.
Send the grade code, your annual volume and ship-to location. A polymer chemist checks it before we quote; we were founded by a family with 30+ years in the resin business. For several grades at once, use the resin RFQ template.

Common questions
What is Elastollan C 65 A HPM?
Elastollan C 65 A HPM is a soft, aromatic, polyester-based thermoplastic polyurethane (TPU) from BASF in its HPM (high performance material) series. BASF describes the HPM series as having very good damping and rebound, high temperature resistance, improved setting behavior and good demolding.
What is the hardness of Elastollan C 65 A HPM?
The nominal hardness is 65 Shore A. BASF’s range chart lists the measured value for C 65 A 15 HPM as 67 Shore A (DIN ISO 48-4, 3 s reading).
Is Elastollan C 65 A HPM polyester or polyether?
Polyester. In BASF’s naming, the C series is polyester based, and Material Data Center classifies C 65 A HPM as TPU-ARES (aromatic polyester TPU).
Is C 65 A HPM the same as Elastollan A C 65A 12 HPM?
No. BASF lists A C 65A 12 HPM as an aliphatic polyester grade aimed at color-fast, non-yellowing parts. C 65 A HPM is aromatic. Check the full code on your drawing or bag label.
What is equivalent to Elastollan C 65 A HPM?
The closest grades to ask about are BASF’s own Elastollan C 70 A 15 HPM (harder) and C 60 A 15 HPM (softer, weaker), plus 565 A 12 P, a plasticized polyester TPU at 66 Shore A. None is identical; compare data sheets and run a trial, and get approval if your part names C 65 A HPM.
Does Elastollan C 65 A HPM need drying?
Yes. BASF says Elastollan is hygroscopic and should be dried to below 0.02% moisture before processing. For the HPM product range, BASF’s drying table gives 3–5 hours at 60–80°C in a dehumidified-air dryer and lists circulating-air drying as not suitable.
