Material Type: Two-component (2K), thermosetting polyurethane (PU) resin system.
Target Simulation: Engineered to closely mimic the mechanical properties and appearance of engineering-grade ABS plastic.
Key Properties:

• Tensile Strength: High, typically around 45-50 MPa (approx. 6500-7250 psi).
• Flexural Strength: High, typically around 70-80 MPa (approx. 10,000-11,600 psi).
• Elongation at Break: Moderate, typically around 10-15%.
• Hardness: Shore D ~80 (similar to rigid ABS).
• Impact Strength: Moderate (Izod Notched approx. 20-30 J/m).
• Heat Deflection Temperature (HDT): Typically around 50-60°C (122-140°F) at 0.45 MPa / 66 psi; usable for prototypes up to ~80°C (176°F) short-term.
• Viscosity: Low viscosity mix (A+B components), excellent for degassing and flow into complex molds.
• Cure Time: Fast demold times (often 45-90 minutes depending on part size/thickness), enabling multiple casts per day.
• Mix Ratio: Typically 100A : 85B by weight (always check the specific Technical Data Sheet - TDS).
• Shrinkage: Low, designed for dimensional accuracy in casting (~0.15%).

VACUUM CASTING PROCESSING CONDITIONS 

Primary Use: Rapid Prototyping of functional parts requiring ABS-like properties.
Key Industries & Applications:

• Automotive: Interior trim components (panels, knobs, vents), housings, ducting prototypes, fluid reservoirs, connector prototypes.
• Consumer Electronics: Housings for phones, tablets, appliances, remote controls, power tool casings, buttons.
• Industrial Equipment: Covers, housings, enclosures, handles, levers, jigs, fixtures.
• Medical Devices (Non-Implantable): Prototypes for device housings, handles, ergonomic grips, casings for diagnostic equipment (ensure biocompatibility is not claimed for PX215 unless explicitly certified for a specific use).
• Telecommunications: Prototype enclosures for routers, modems, handsets.
• General Product Design: Functional concept models, ergonomic studies, design verification prototypes, presentation models, small-batch end-use parts (where properties suffice).

Excellent Fit: PX215 is specifically formulated for the vacuum casting process.
Key Adaptations:

• Low Viscosity: Ensures easy mixing, thorough degassing under vacuum, and complete filling of intricate mold details and thin walls in silicone molds.
• Vacuum Degassing: Essential for achieving bubble-free casts; PX215 degasses efficiently before pouring.
• Fast Cure: Allows for relatively quick demolding (typically 45-90 mins), maximizing productivity from a single silicone mold.
• Silicone Mold Compatibility: Performs well with standard RTV (Room Temperature Vulcanizing) silicone molds used in the process.
• Mold Life: Produces 15-25 high-quality parts from a single silicone mold, depending on part complexity and demolding care.

• ABS-Like Properties: Offers the closest simulation of ABS plastic mechanical behavior (strength, rigidity, hardness) among common vacuum casting resins.
• Fast Turnaround: Quick demold time speeds up prototyping iterations and small-batch production.
• High Detail Reproduction: Excellent flow captures fine details, textures, and complex geometries from the silicone mold.
• Good Surface Finish: Produces smooth surfaces ready for painting or finishing; minimal post-processing often needed.
• Dimensional Stability: Low shrinkage ensures good accuracy compared to the master pattern.
• Paintable & Glueable: Easily accepts paints, adhesives, and secondary operations like machining or tapping.
• Cost-Effective for Low Volumes: Ideal for producing 10s to low 100s of functional prototypes or end-use parts without expensive injection molding tooling.

• Not Production Plastic: While simulating ABS, it lacks the long-term durability, precise thermal stability, and impact resistance of true, injection-molded ABS, especially at higher temperatures or under sustained stress/UV.
• Limited Heat Resistance: Unsuitable for applications requiring sustained high temperatures (>80°C / 176°F).
• UV Sensitivity: Like most PU resins, prolonged UV exposure will cause yellowing and degradation unless protected.
• Mold Life Constraint: Silicone molds degrade over time (15-25 pulls), limiting the total number of parts per mold compared to metal tooling.
• Lower Impact Strength than some ABS Grades: While rigid, its impact resistance can be lower than certain toughened ABS formulations.
• Moisture Sensitivity: Components can absorb moisture; storage and handling according to TDS are crucial.

• Axson Technologies: PX215 was originally developed and branded by Axson Technologies, a leading manufacturer of industrial resins (polyurethanes, epoxies) for prototyping, tooling, and composites.
• Current Status: Axson Technologies was acquired by ALTANA (specifically the ELANTAS PDG division) in 2018. The Axson product line, including PX215, is now manufactured and distributed under the ELANTAS PDG (Prototyping, Design, and Modeling) brand within the ALTANA Group. You will find it listed as ELANTAS PX215 or sometimes still referred to as Axson PX215. Distributors like Freeman Supply carry the line.

Within Axson/ELANTAS PDG:

• PX223 / PX221: Higher impact strength variants (simulating ABS+PC or tough PP), slightly lower rigidity than PX215.
• PX256: Simulates rigid Polypropylene (PP), lower strength/higher flexibility.
• FC52 / FC53: Simulates Polycarbonate (PC), higher heat resistance and impact strength than PX215.

Competitor Resins (Similar ABS Simulation):

• Smooth-On Task Series (e.g., Task 9): Widely used US brand, offers resins with similar ABS-like properties.
• Polytek Poly 74xx Series (e.g., 74-29): Another major US supplier, known for robust casting resins.
• Huntsman RenShape® SL Series: High-performance tooling and prototyping resins, some grades simulate engineering plastics.
• VarioCast / VarioKast (Germany): Common European alternatives.
• Axson/ELANTAS PDG PX271: A newer alternative sometimes positioned similarly to PX215.

Alternatives for Different Properties:

• Simulate PP: PX256 (Axson), Task 12 (Smooth-On), Poly 74-45 (Polytek).
• Simulate PC/High Impact: FC52/FC53 (Axson), Task 8/15 (Smooth-On), Poly 74-20 (Polytek).
• Simulate PE/Flexible: PX242 (Axson), Task 4 (Smooth-On), Poly 74-30 (Polytek).
• High Temp/Specialty: Epoxy-based resins (e.g., Axson/ELANTAS PDG PX521), or specialized high-temp PU (e.g., Smooth-On Somos® Taurus).
