Frame Materials Flashcards
pros of this metal include flexibility ( can return to original shape after being damaged); hypoallergenic, lightweight, strong, and corrosion resistant
flexon
this type of plastic has diff characteristics such as hypoallergenic and lightweight ; its not strong and not flexible
zyl
this is a relatively new material with myriad of uses; silver gray metal; high quality, value added frame product
titanium
pros of this type of plastic include wide variety of shapes and colors; very lightweight; great shape and adjustment retention ; hypo allergenic; heat resistant; resistant to most solvents
optyl
What are some diff types of metal
Al, monel, titanium, flexon, beryllium, stainless steel
cons of this metal include not available in a variety of colors
flexon
cons of zyl include :durable but becomes brittle with age, can lose surface luster with age, certain colors can fade; sensitive to solvents; heavier than plastic frame material
zyl
pros of this type of plastic include reasonable variety of colors; durably and color fast; less surface dulling; good flexibility; lightweight and hypoallergenic
propionate
this is the most widely used material/ alloy in manufacture of metal eyeglass frames; nickel is the largest component
monel
pros of this metal : great strength and durability.; 40 % lighter than other metals; excellent surface hardness; impervious to corrosion ; hypoallergenic ; comes in variety of colors
titanium
this type of plastic is hypoallergenic, lightweight, and flexible. Not strong
propionate
this type of metal has early departure from traditional gold filled frames; been surpassed by more modern materials; used on limited basis; lightweight, strong, and corrosion resistant
Aluminum
cons of this metal include the cost ; subtle frame adjustments can be hard to make ; not hypoallergenic
beryllium
what are some other metal materials
bronze, cobalt, copper, Magnesium, Nickel, Nickel Silver, Palladium, Phosphorus Bronze, Ruthenium, Trilliam
cons of this type of plastic include difficult to dye; heat sensitive; not well suited to stretching or shrinking ; sensitive to solvents ( alcohol, acetone, etc)
propionate
what are most nose pads made of
acetate, vinyl, silicone, hypoallergenic
this metal has flexible and is corrosion resistant
monel metal
What are the main materials frames are made from
plastic and metal
this metal resists corrosion and tarnish ; resists corrosion and tarnish > excellent choice for pts with high skin acidity or who spend time in /around salt water; very flexible; available in several colors
beryllium
What are some frame accents
silver, gold, leather, velvet, semi precious stones, precious stones, rhinestone, feathers
What are some other frame materials
wood, bone, buffalo horn
type of plastic most popular material for plastic frames; made out of cellulose acetate ; thermoplastic
zyl
cons of this metal include: expensive, not flexible; requires special welding equipment in frame fabrication
titanium
this type of plastic is made from epoxy resin; they are thermoelastic
Optyl
what type of metal has these pros: lightweight, strong, and corrosion resistant; low density; long lasting; can come in several colors
aluminum
this is a steel gray metal; increased popularity as a lower cost alternative to titanium eyewear
beryllium
advantages of this type of plastic include cost effective; wide variety of colors; fast/stable; can be worked easily; allows some margin for sizing errors; reasonably lightweight; and hypoallergenic
zyl
what type of metal has these cons: difficult to achieve good lens fit without gapping; difficult to adjust ; complication manufacturing ; poor color finish ; not hypoallergenic
aluminum
these are coatings often used to seal the surface; it contains UV inhibitor ( keeps from fading)
frame coatings
this is aka zyl, propionate, optyl, and other plastic materials
plastic frame
cons of this metal include difficult adjustments and do not hold due to spring nature
stainless steels
cons of this metal include : may be difficult to shape or reshape during dispensing; medium corrosion resistance; not hypoallergenic, lightweight, or strong compared to other metals
monel
cons of this type of plastic: difficult to adjust, requires more heat to to work ; will not shrink
optyl
this metal is an alloy of steel and chromium; lightweight and strong; will not react with skin; excellent corrosion resistance; resistant to abrasion and heat
stainless steel
pros of this metal are cost effective and efficient ; can be really malleable /flexible and has good resistance to stress; accommodates well to eyewire curves; corrosion resistant with proper plating/coating
monel
this metal is a titanium based alloy; proprietary to the eyewear manufacturer Marchon; aka memory metal, smart metal, smart alloy
flexon
pros of this lens: lightweight, strong, flexible, and corrosion resistant
beryllium
this type of plastic is cellulose acetyl- propionate ; nylon based
propionate
