ALL ABOUT FRAME MATERIALS
With its endless coloring possibilities, acetate can be laminated, patterned, or even layered with fabrics or chip patterns to achieve the most beautiful colors that have depth, making each frame as unique as a fingerprint. This material is one of the more creative and workable options. Cellulose acetate, also know as zyl, is the most commonly used non-metal frame material and is available in every color of the rainbow. Today's most premium of fashion brands use acetate as their flagship material of choice.
Acetate is easily milled into today's popular styles and has unlimited coloring possibilities.
Acetate frames have some drawbacks in fit. Proper fit requires a skilled professional opticians. Park Place Optical -- has the skilled optical technicians to properly custom fit your new acetate frames.
Titanium is a high-strength, lightweight material commonly used in everything from hubcaps to eyewear. Because titanium ranks seventh in abundance among industry elements in the earth's crust, it is easily accessible. This material has picked up speed in the eyewear industry as a lightweight option that lends itself to unique designs and colorations.
Titanium is as strong as steel, lightweight, hypoallergenic, and corrosion-resistant.
This material is more expensive than other materials. Beware of the difference between "pure titanium" and "titanium alloy."
STAINLESS STEEL FRAMES
Stainless Steel material is an alloy of iron and carbon steel with chromium and other elements. The addition of at least 10 percent chromium makes this alloy less prone to stain or rust, a factor that results in a long life compared to that of traditional steel. Because of its durability, light weight, and sleek appearance, stainless steel has long been a choice of premium eyewear designers.
Stainless steel is non-corrosive, durable, strong, lightweight, and hypoallergenic. It can also be easily shaped into ultra-thin eyewear styles and has flexibility, which adds to the wearer's comfort.
Stainless is still not as lightweight, heat-resistant or flexible as titanium.
Grilamid is also a premier material for sports and performance frames and is also used in fashion frames where a thinner profile is desired. While acetate frames are milled from colored sheets of acetate, Grilamid frames are injection molded, usually using clear pellets and then colored, using various methods once the frames have been cured. Typically made of a high quality thermoplastic material and sometimes with the addition of nylon that is shock resistant, lightweight and non-allergenic. Grilamid is also more heat resistance and will maintain shape integrity, even in extreme heat conditions. This material is used to manufacture Rudy Project sunglass frames. It provides structural integrity and stability that is very resistant to hot, cold and chemical damage.
Grilamid and Nylon is easily molded into today's popular wraparound styles. Grilamid also has the added benefit of being very stable in extreme temperatures which means fewer adjustments necessary, over time.
Grilamid and nylon injected frames do have some drawbacks in fit. Be certain of proper fit initially since the adjustments are limited.
MEMORY TITANIUM FRAMES
Nickel Titanium or NI-TI is used to manufacture Flexon™ eyewear. Ni-Ti, or titanium-based alloys, are more flexible than steel and 25% lighter than conventional metals.
Flexibility removes the need for spring hinge and increases comfort and durability for patients who are hard on their eyewear.
Since all Ni-Ti is nickel based, allergies and pitting may be an issue.
Monel is a nickel alloy containing 68 percent nickel, 30 percent copper and two percent iron. Monel,™ the most commonly used frame material today, is often used for components that require sturdiness and rigidity, such as temples and bridges.
This alloy is strong and it can also be welded, brazed, and soldered.
Surface discoloration can occur from exposure to atmospheric conditions. Pitting can also occur if exposed to salt water.
