PSU-Solvay Udel P-1700
Sustaining clear optical transparency and high mechanical strength under continuous steam exposure up to 149°C requires a specialized amorphous backbone, which Syensqo’s Udel P-1700 (formerly Solvay) delivers through its unreinforced, high-purity polysulfone (PSU) matrix. Featuring a density of 1.24 g/cm³ and a melt flow rate of 6.5 g/10 min, this rigid polymer complies with FDA 21 CFR 177.1655, NSF 51, and NSF 61 regulatory standards for food and water contact. Jucheng Precision, operating under ISO 13485 and ISO 9001 certified systems, excels in high-temperature cleanroom molding of Udel P-1700. Utilizing in-house 5-axis CNC-machined S136 stainless steel tooling, we eliminate volatile splay and cooling voids, delivering flawless medical components verified by Zeiss CMM.

PSU-Solvay Udel P-1700 Tooling & Moisture Outgassing Blueprint
Molding an amorphous high-viscosity resin like Udel P-1700 requires precise gate sizing to prevent high melt pressures, alongside thorough pre-drying:
Desiccant Drying & Splay Prevention
Polysulfone is highly hygroscopic. Moisture causes cosmetic splay, bubbles, and loss of transparent optical quality. We pre-dry the raw resin in desiccant hopper dryers at 135°C–163°C (275°F to 325°F) for 3.5 hours, keeping moisture strictly below 0.05% to secure optimal structural density.
Isotropic Low Shrinkage & Dimensional Stability
Udel P-1700 exhibits low and highly uniform shrinkage (typically 0.70%) due to its amorphous matrix. We machine precise core and cavity blocks on our 5-axis CNCs, ensuring that the molded parts are completely flat and warp-free.
High-Temperature Melt & Mold Control
Processing barrel temperatures are maintained between 329°C and 385°C (625°F to 725°F) to ensure homogeneous flow. Mold temperatures are kept at 121°C to 163°C (250°F to 325°F) using pressurized oil temperature controllers to reduce internal molding stresses.
Rust-Resistant Tool Steel (S136 steel)
To prevent mold rust and ensure optical-grade part finishes, we construct mold cavities from premium S136 stainless steel, mirror-polished to a high level. This ensures that the molded parts release cleanly without drag marks during automated runs.
