What are the advantages of PU polyurethane dental handrails?

The Five Core Advantages of PU Dental Armrests
1、 Excellent durability and anti-aging performance. The Shore hardness range of PU material (polyurethane) can reach 30A-80A, and the surface abrasion resistance index exceeds 500000 friction cycles, far exceeding that of traditional PVC or ABS materials. For example, in the scenario of 200 patient uses per day, the wear rate of the dental chair armrest is less than 3% within 5 years. It can tolerate commonly used medical disinfectants such as 75% alcohol and hydrogen peroxide. Experimental data shows that after continuous soaking for 500 hours, the material expansion rate is less than 0.2%, and there is no cracking or delamination phenomenon.

2、 Medical grade health and safety guarantee
Using a silver ion/zinc oxide composite antibacterial agent, the inhibition rate of Escherichia coli and Staphylococcus aureus is greater than 99.9% (ISO 22196 standard), reducing the risk of microbial attachment by 70% compared to stainless steel materials. Active antibacterial technology is adopted. By using in mold foaming technology, the 3-5mm seam dead angle of traditional spliced handrails is eliminated, and the cleaning efficiency is improved by 60%. Compliant with FDA 21 CFR 177.1680 (indirect food contact materials) and ISO 10993 biocompatibility standards, certified with zero detection of 6P phthalates and REACH SVHC 235 hazardous substances.

3、 Ergonomic optimization design
Surface hardness gradient design (front end 65A/back end 45A), simulating palm pressure distribution curve, reducing patient grip fatigue by 42%, thermal conductivity of 0.23 W/(m · K), reducing winter tactile temperature difference by 12 ℃ compared to metal materials, supporting 0-90 ° angle locking, 30cm length extension and contraction, suitable for full scene requirements from children's dental chairs (minimum 40cm) to accessible diagnosis and treatment positions (maximum 110cm).
