Technical resources
Technical articles across our five product lines and 3D printing — how materials behave, how grades are selected, and the data behind each application.
Medical TPU
Oct 30, 2026Radiopaque medical TPU: barium-sulphate-filled polycarbonate for X-ray visibilityPolycarbonate TPU carrying a barium sulphate (BaSO4) filler makes the device itself visible under X-ray, removing the need for welded marker bands in cardiovascular, neuro and peripheral devices.Oct 30, 2026Implant-grade TPU: what the 52-week implantation data actually showsLong-term implant is the hardest gate in medical materials. Here is the evidence behind the NLMD implant-grade range: full hardness certification, master-file registration for five polycarbonate grades, and a 52-week intramuscular irritation index of 0.0.Oct 30, 2026NLMD65 series: aliphatic polycarbonate TPU for long-term implantationPolycarbonate soft segments remove the ester linkage that hydrolyses, and an aliphatic hard segment avoids the aromatic degradation route. Together they are what makes a TPU survive years in a blood-contact implant.Oct 30, 2026Medical-grade TPU vs industrial TPU: what actually differsMedical grade is not a purer industrial grade with a markup. It is a different evidence package: ISO 10993 evaluation, extractables control, medical QMS traceability, and a master-file route that saves the device maker registration time.
Wire & Cable TPU
Oct 30, 2026TPU for medical-device cables: disinfectant resistance with biocompatibilityMedical-device cables face repeated disinfection and skin contact. Modified TPU jacketing balances biocompatibility, disinfectant resistance, flexibility and halogen-free flame retardancy.Oct 30, 2026Permanent antistatic TPU masterbatch: surface resistance without migrationConventional antistatic additives migrate, bloom and stop working once they are gone. A polymer-type antistatic masterbatch builds a permanent conductive network in the matrix instead — 10^8 Ω/sq, stable, and 10–20% let-down.
Supercritical Foaming TPU
Oct 30, 2026Supercritical foaming TPU for lightweight, high-rebound footwearSupercritical physical foaming with CO2 or N2 turns TPU into a lightweight, high-rebound closed-cell microfoam — overcoming the density and uniformity limits of chemical foaming.Oct 30, 2026Qingdi™ series: slip-resistant, abrasion-resistant TPU outsoles at 60–65 Shore ARubber grips but wears and cannot be recycled. Conventional TPU wears well but slips. The Qingdi™ series is built to break that trade-off for safety and outdoor footwear outsoles — 60–65 Shore A, wet and dry grip comparable to rubber, fully recyclable.
Paint Protection Film TPU
Oct 30, 2026Aliphatic TPU for paint protection film: optical clarity and self-healingPCL-based aliphatic TPU particles for optically clear protective film — self-healing, UV and weather resistant, plasticizer-free and compatible with adhesives, inks and coatings.Oct 30, 2026Matching imported PPF TPU: the four numbers that decide itDomestic substitution in paint protection film is not a price argument — it is a colour-shift argument. Four measurements decide whether an aliphatic TPU actually replaces an imported grade: QUV colour shift, tear strength, process stability and adhesive compatibility.Oct 30, 2026How domestic PPF TPU caught up: a supply-chain viewPaint protection film was localised in China layer by layer — coating first, base film last. This is the sequence of gates the last layer had to pass, and why the bottleneck sat upstream of the film plant.
