There are several materials between eyeglasses eyeglass plastic, metal and a combination of the two composites , Glassesshop.com selects materials that are cost effectively, adjust easily, offer safely and workability, hold the lenses properly, and resist splitting, corrosion, and heat. You can find your fashion glass frame material from following materials :
1.Plastics
Cellulose acetate (zylonite): The most commonly used plastic in eyeglass
frames, cellulose acetate is relatively inexpensive, easy to use, and
comes in a wide variety of colors, textures, and patterns. The material
is easily adjusted but tends to get brittle with age.
Cellulose proprionate: This is a lightweight material that can be
injection molded making it ideal for intricate designs. Care must be
taken when heating and adjusting frames because it will shrink and ruin
with overheating.
Kevlar: Developed by DuPont for use in bulletproof vests, this plastic
can withstand high impact such as that experienced in sporting events.
The material is limited because it will not shrink or stretch, and it
comes in few colors.
Nylon: Many sports and safety glasses
are made of nylon because it is virtually unbreakable and relatively
lightweight. The material is, however, difficult to adjust and can be
manufactured only in darker colors. It can also become brittle over
time.
Optyl: This material is somewhat lighter in weight than cellulose
acetate and is hypoallergenic, an advantage to skin-sensitive patients.
Frames made of optyl are more difficult to adjust because the material
can return to its original molded shape, and the frames may break easily
if not heated properly.
Polycarbonate: Polycarbonate is 10 times more impact-resistant than
conventional plastic or glass and is the best material for children’s,
sports, and safety glasses.
Polycarbonate lenses are thinner and lighter than conventional plastic
or glass lenses, and the material comes with built-in ultraviolet
protection.
2. Metals
Aluminum: Although very lightweight, aluminum is difficult to solder or weld, limiting its adaptability to different designs.
Cobalt: Usually used as part of a metal alloy, cobalt appears in
high-quality frames that can be made lightweight, durable, flexible, and
thin. It can also be successfully coated with a variety of colors, but
is very expensive and consequently limited in use.
Monel: It is one of the most popular materials used in metal frames
because it can be hammered into many shapes without losing its strength.
It can also be made in various colors.
Nickel silver: This is a common material used in hinges, end pieces, and
heavy bridges, and the inner core of temples. It is more brittle than
several other metals, making it less suited to the slender frames so
popular today.
Phosphor bronze: This flexible alloy is about 95 percent copper, making it a good choice for temples.
Stainless steel: Stainless steel is one of the most corrosion-resistant
metals, but is difficult to work with in the manufacturing process.
Trilam: This product is lightweight; however it has a memory, which makes frame adjustments be difficult.
3. Composites
Carbon fiber graphite (CFG): CFG is a material made of nylon and carbon
that provides the endurance of metal frames but is thin and lightweight.
Although the material is black in its natural state, it is now
available in a wide range of colors.
Copolyamide (MXP7),It is a material with a blend of nylon manufactured
for frame-injection molding. The material is strong, lightweight, and
durable, and it retains its shape unless heated.
Titanium Ti-227: Titanium Ti-227 is nearly 50 percent lighter than most
metal frame materials. It is hypoallergenic, noncorrosive, and one-third
stronger than steel, making it an extremely desirable material for
manufacturing frames. It’s also difficult and expensive to extract and
refine this abundant material. It is the most hot and fashion glasses frame for the light weight and durable usage .
