FAQs\u00a0<\/strong><\/p>\n

Q1: What is the difference between TPU and TPE treads on these casters?<\/strong>
\nA: Both materials offer industry-leading noise reduction and floor protection.<\/p>\n

Our 75mm and 100mm models utilize premium TPU (Thermoplastic Polyurethane) for optimal wear resistance under concentrated loads.<\/p>\n

The 120mm model incorporates high-grade TPE (Thermoplastic Elastomer), which maximizes shock absorption<\/p>\n

and rolling smoothness for larger-diameter, heavy-duty applications.<\/p>\n

Q2: Are these casters suitable for chemical and medical environments?<\/strong>
\nA: Yes. The main frame and core are built from Nylon (PA6), which provides outstanding chemical stability.<\/p>\n

It is highly resistant to industrial oils, common detergents, alcohols, and pharmaceutical compounds,<\/p>\n

ensuring a long lifecycle in hospitals and laboratories.<\/p>\n

Q3: Do these wheels comply with international quality standards?<\/strong>
\nA: Absolutely. All three sizes (75mm, 100mm, 120mm) are strictly manufactured and certified under the EN12531 standard,<\/p>\n

guaranteeing reliable load ratings, structural safety, and environmental compliance.<\/p>\n","protected":false},"excerpt":{"rendered":"
