描述
VESTAMID X7229 is a high-viscosity, plasticized, heat-stabilized and self-extinguishing polyamide 12 compound from Evonik Operations GmbH developed for aircraft, railway and ship interior applications.
The grade contains a non-migrating flame-retardant system that is free of both halogen and phosphorus. This is the central technical feature of VESTAMID X7229, because transportation interiors increasingly require flame performance together with low-smoke, low-toxicity and halogen-free material concepts.
Evonik states that VESTAMID X7229 complies with the requirements of FAR 25.853 and ABD 0031. These standards are highly relevant to aircraft interior materials and are one of the main reasons this grade is selected for profiles, tubes and other interior components.
Evonik also lists approval of X7229 under Airbus material specifications AIMS 04-01-004A and AIMS 04-01-004B in its quality and approvals information.
The material is plasticized, which makes it substantially more flexible than rigid flame-retardant PA12 grades such as X7167. That flexibility is useful for profiles, protective tubes, cable-protection tubing and interior components that must combine flame resistance with impact durability and bendability.
The designation PA12 FR(30) is a material classification. It should not be interpreted as meaning that the resin contains 30% flame retardant.
Current Evonik-derived data identifies VESTAMID X7229 as a high-viscosity grade with an MVR of approximately 26 cm³/10 min at 220°C / 10 kg. The combination of high viscosity and plasticization helps provide extrusion stability while retaining flexibility.
The current dry tensile modulus is approximately 980 MPa, yield stress approximately 36 MPa, yield strain approximately 17%, and nominal strain at break greater than 50%. These values clearly show that X7229 is more flexible and ductile than rigid electrical PA12 grades.
Impact performance is another strength. Current data reports no break in the unnotched Charpy test at both 23°C and -30°C, while notched impact strength is approximately 11 kJ/m² at 23°C and 5 kJ/m² at -30°C.
Thermal data includes a melting temperature of approximately 175°C, HDT of approximately 40°C at 1.80 MPa and 130°C at 0.45 MPa, and Vicat B softening temperature of approximately 150°C.
The grade also provides the chemical resistance, abrasion resistance, low moisture sensitivity and low-temperature toughness associated with VESTAMID PA12.

| Phosphorus-Free | Yes |
| Flame-Retardant Migration | Non-migrating system |
The transportation compliance profile is the main reason VESTAMID X7229 is preferred over general-purpose plasticized PA12.
Why Choose VESTAMID X7229?
The main reason to choose VESTAMID X7229 is that it combines flame-retardant transportation compliance with flexibility.
Aircraft, railway and ship interiors require materials that do more than simply withstand heat. Components often need low smoke, low toxicity, controlled flame spread, mechanical durability and predictable behavior over long service periods.
Rigid flame-retardant materials can satisfy fire requirements but may not provide the flexibility needed for tubing or profiles.
The plasticized PA12 base of VESTAMID X7229 provides a more flexible balance. A tensile modulus around 980 MPa is substantially lower than rigid FR PA12 such as X7167, while elongation above 50% provides useful deformation capability.
The material also retains strong low-temperature toughness. No-break unnotched Charpy behavior at -30°C is valuable for transportation systems that can experience large temperature changes during storage, operation or maintenance.
The non-migrating flame-retardant system is another important advantage. Additive migration can affect surface appearance or long-term consistency in some polymer systems. Evonik specifically describes the X7229 flame retardant as non-migrating.
The absence of halogen and phosphorus also supports modern material-selection policies that seek to reduce halogenated flame-retardant chemistry.
For aircraft programs, the FAR 25.853 / ABD 0031 positioning and Airbus AIMS approvals make the grade much more application-specific than ordinary V-2 PA12.
For rail, ship and public-infrastructure cable protection, the combination of flame resistance, chemical resistance, abrasion resistance and PA12 toughness is equally valuable.
Processing Guidelines for VESTAMID X7229
VESTAMID X7229 can be processed by extrusion and injection molding.
Evonik provides clear grade-specific temperature guidance:
| Processing Parameter | Published Guidance |
|---|---|
| Recommended Melt Temperature | 210–230°C |
| Maximum Melt Temperature | Do not exceed 260°C |
| Primary Processes | Extrusion and Injection Molding |
| Main Extrusion Products | Profiles and tubing |
| Delivery Form | Cylindrical Pellets |
| Shelf Life | At least 2 years in original undamaged packaging at ≤30°C |
The manufacturer specifically warns that processing temperatures should not exceed 260°C because of the flame-retardant system.
For profile and tube extrusion, optimize:
- Barrel-temperature profile
- Adapter and die temperature
- Screw speed
- Melt pressure
- Line speed
- Profile or tube dimensions
- Draw-down
- Cooling conditions
- Surface quality
- Dimensional stability
For injection molding, optimize:
- Melt temperature
- Mold temperature
- Injection speed
- Holding pressure
- Gate geometry
- Cooling time
- Shrinkage
- Surface quality
Evonik supplies VESTAMID compounds dry in moisture-proof packaging. Fresh material from an intact package normally does not require additional drying.
For material exposed after opening, Evonik’s cable-processing guide recommends dry-air drying for VESTAMID at approximately 90–100°C for at least 2 hours, with moisture content below approximately 0.10% before processing.
