What is High Temp?
High Temp Resin is a highly crosslinked, filled photopolymer for SLA and DLP printing under GB/T 35022, with a heat deflection temperature of 200–290 °C at 0.45 MPa after thermal post-cure. It is used for tooling exposed to hot air, hot liquids or thermoforming, and for stiff prototypes, offering 48 MPa tensile strength, 3.3 GPa modulus and Shore D 86 with a continuous service temperature near 110 °C. The high crosslink density leaves only 3.2% elongation, so the material is brittle and notch-sensitive, and it yellows under UV; for flexible or impact-loaded parts use Durable Resin. High Temp has a density of 1.19 g/cm³ (0.043 lb/in³), heavier than 53% of polymer grades. Its glass-transition temperature is 130°C (266 °F). High Temp has a tensile strength of 50 MPa (7.25 ksi), stronger than 54% of polymer grades. Elongation at break is 2.8% and the elastic modulus is 3.5 GPa (0.508 Msi).

Physical3
High Temp has a density of 1.19 g/cm³ (0.043 lb/in³), heavier than 53% of polymer grades. Its glass-transition temperature is 130°C (266 °F).
Mechanical10
High Temp has a tensile strength of 50 MPa (7.25 ksi), stronger than 54% of polymer grades. Elongation at break is 2.8% and the elastic modulus is 3.5 GPa (0.508 Msi).
Thermal8
High Temp is rated for continuous service to 150°C (302 °F). It conducts heat at 0.2 W/m·K (0.116 BTU/hr·ft·°F), worse than 56% of polymer grades. Thermal expansion is 75 µm/m·K (41.7 µin/in·°F).
Electrical3
High Temp has an electrical resistivity of 1×10¹² Ω·m.
Chemical & Environmental3
Corrosion resistance is very good (70/100), worse than 78% of polymer grades. UV resistance is fair.
Sustainability3
Producing a kilogram of High Temp takes about 110 MJ of energy and emits 5.5 kg of CO₂ — more than 64% of polymer grades. Typical recycled content is 0%.
Manufacturability2
High Temp's machinability is good (55/100, worse than 64% of polymer grades).

Working with High Temp
Is High Temp easy to machine?
Drills, taps and mills cleanly with sharp carbide and light feeds, but is notch-sensitive — chamfer edges, avoid deep unsupported cuts and keep it cool.
Can High Temp be welded?
Not weldable (thermoset); join with epoxy or methacrylate adhesives, or design mechanical/threaded-insert joints.
Can High Temp be formed, bent or molded?
Formed only by SLA/DLP printing at 405 nm — use generous wall thickness and supports, isopropanol wash, full UV cure, then the oven thermal post-cure to unlock the 238 °C HDT.

What surface finishes work on High Temp?
Sand and polish or bead-blast to hide layer lines; prime and paint for cosmetic parts and use an opaque coating outdoors, since bare resin yellows and embrittles under UV.

High Temp — frequently asked
What is High Temp used for?
High Temp is typically used for vacuum forming moulds, low-volume injection moulding inserts, hot-air and hot-liquid flow fixtures, aerospace prototypes, casting and pattern tooling and heat-resistant inspection fixtures. In short: high-heat photopolymer resin.
What is the tensile strength of High Temp?
High Temp has a typical tensile strength of 50 MPa (7.25 ksi) — stronger than 54% of polymer grades.
Is High Temp easy to machine?
Reasonably — machinability is rated good (55/100, worse than 64% of polymer grades). Drills, taps and mills cleanly with sharp carbide and light feeds, but is notch-sensitive — chamfer edges, avoid deep unsupported cuts and keep it cool.
Can High Temp be welded?
Not weldable (thermoset); join with epoxy or methacrylate adhesives, or design mechanical/threaded-insert joints.
What surface finishes work on High Temp?

What is the maximum service temperature of High Temp?
High Temp is rated for continuous use to about 150°C (302 °F), and briefly to 230°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
