What's the difference between memory plastic and sheet metal?
Market memory plate glasses, refers to the use of TR90 material frame, collision, extrusion deformation, afraid of exposure to some chemicals, like alcohol, as little exposure
1, light weight: about half with plate weight, half nylon material 85%, reduce bridge nose, ear burden, make wear more comfortable and comfortable2, bright colors: more colorful than ordinary plastic frame color3, resistance to impact: nylon material 2 times ISO180/IC:>125kg/m2 elastic effect, to prevent the impact of eye damage4, high temperature: 350 degrees high temperature resistant short ISO527: anti deformation index 620kg/cm2 melt combustion frame deformation discoloration make frames to wear more5. Safety: the release of residues meets the requirements of European food grade materialsTR90 material is more expensive than its PCCP and other frame materials, and the manufacturing process is more stringent, the TR90 frame price is several times more expensive than it
TR 90 (plastic titanium) with memory materials with high current international popular ultra light frame material with high toughness and wear resistance and low coefficient of friction against energy transport frame fracture, prevent friction damage eyes and face made its specific structure anti resistance high temperature deformation resistant short between 350 degrees high temperature melt combustion residues release in line with European food grade material TR90 glasses surface lubrication density of 1.14-1.15 salt water than the floating plastic spectacle frame and plate frame about less light weight nylon 85% half bridge of the nose, ears for reducing burden youth use of anti-wear and anti aging, good solvent resistance, weather resistance, easy combustion, high temperature resistance and memory high resistance material deformation index 620kg/cm2 variant TR90 spectacles frame material elasticity, toughness and easy fracture strength fracture with operation safety and impact resistant nylon material: 2 times ISO180/IC:>125kg/m 2 elasticity to prevent eye damage caused by movement
The use of high-tech plastic sheet manufacturing: the number of memory sheet of acetate fiber fiber cellulose acetate propionate frames a few high-grade plate type injection molding pressing type injection molding type name for grinding the number of pressing grinding sheet glasses sheet production sheet is more than words ILLY high-end sheet glasses based on the wrong quality some more trust value of high quality sheet metal mold design: designed wide irrigation still, the pursuit of quality tailor-made features: simple design style and restrained overall performance using just emphasizes the coloring process leg line stereo change
