Eyewear Frame Material Quality Verification 2026: Acetate, TR90, and Titanium Standards | SCM Group HK

Eyewear frame manufacturing in 2026 demands rigorous material quality verification across three primary materials: cellulose acetate (acetate), thermoplastic (TR90), and titanium alloys. Each material requires distinct testing protocols, certification pathways, and production specifications. This technical guide details MOQ standards, quality verification procedures, and certification requirements for OEM frame production.

Acetate (Cellulose Acetate) Material Standards

Acetate frames represent 40% of global eyewear production. Material specifications: shore hardness D 80-85, tensile strength ≥40 MPa, color fastness grade 4-5 (ISO 105-B02). Minimum order quantity (MOQ) starts at 100 frames per color variant for standard sizes. UV resistance testing (ASTM G154) ensures long-term durability. Acetate sourcing requires traceability from certified material suppliers, with batch testing every 500kg.

TR90 and Titanium Material Verification

TR90 thermoplastic frames require impact resistance testing (ANSI Z80.3 standards): 50g steel ball drop from 1.27m height without frame fracture. Titanium alloys (typically β-titanium or pure titanium grade 23) demand hypoallergenic certification and salt-fog corrosion testing (ASTM B117) for minimum 500 hours. MOQ for TR90 is typically 200 frames, titanium 150 frames due to higher material costs and precision machining requirements.
