Plastic marked by a high softening temperature and high impact strength, sometimes used for eyeglass lenses and frames.
Any group of hard thermoplastics with great resistance to impact and softening.
A high-index plastic that is used to make spectacle lenses that are very resistant to impact.
Impact resistant and flame-retardant thermoplastic, far stronger than acrylic and Plexiglas used for vision panels.
Durable, impact-resistant plastic; see Makrolon
The transparent plastic material used to form the substrate for compact discs.
Plastic lenses that are particularly durable and impact resistant.
Engineering plastic used for the shell and substrate of Sony magneto optical disks.
Polymers derived from the direct reaction between aromatic and aliphatic dihydroxy compounds with phosgene or by the ester exchange reaction with appropriate phosgene derived precursors. Structural units are linked by carbonate groups.
Remarkable strong plastic. It weighs the least and is the most impact-resistant making it a perfect choice for rugged sunglass frames and lenses. The lens will also offer built-in ultraviolet protection.
A type of plastic used in sign faces, noted for its heat-resistance andimpact strength.
Translucent, tough and rigid thermoplastic with low moisture absorption and good stability at temperature extremes.
Generic name for the brand name plastic Lexan used to make highly shatter resistant ophthalmic lenses and a wide variety of other products which require optical clarity and shatter resistance (Space Shuttle windows, jet fighter canopies, bullet proof "glass")
A very strong type of plastic often used in safety glasses, sport glasses, and children's eye glasses. Polycarbonate lenses have approximately 50 times the impact resistance of glass lenses.
Shatter resistant plastic that is lightweight and flexible while maintaining high impact strength. Comes in many different styles.
A plastic that is very impact-resistant, and is very durable. Recommended for all children under 18 due to their active lifestyle. Most beneficial at work and recreational activities where safety is a major concern
The toughest lens material available. Flexes in response to impact, even to the point of being bent permanently without breaking. 20 times more impact resistant than glass. Also very lightweight; 3 times lighter than glass. Polycarbonate is injection molded into lens blanks, UV and IR absorbers as well as lens colour is consistent throughout the lens and cannot be scratched off.
Any of a family of thermo-plastics characterized by a high softening temperature and high impact strength (Lexan).
Plastic that is very impact-resistant, and is thus sometimes used for spectacle lenses and frames.
Clear, tough, shatterproof, virtually unbreakable polymer used to make the lens in flashlights. Often hard coated for abrasion resistance.
A highly durable substrate that is resistant to heat, lightweight and has good electrical properties. It is resistant to mineral acids, organic acids, grease, and oils. Meets MILP-46144 specifications.
This is a very strong and resilient plastic that is used for both bell boxes and control panels. It is, to a certain degree, fire resistant as well. To comply with BS4737 regulations, 3mm thick polycarbonate needs to be used.
A thermoplastic that is heat and moisture resistant. Commonly used for industrial components and also food containers and baby bottles.
Polycarbonates are a group of thermoplastics made up of polymers linked by carbon group. They are a widely utilized plastic particularly for use in clear applications such as CD jewel cases, lenses, and light covers. Some forms are used for single use food containers and water bottles, but the material is not considered food-safe for reused or washed containers.
Extruded plastic sheet that can be glazed singly or as a component of a laminated glazing product.
The toughest lens material available. Flexes in response to impact . It is 20 times more impact resistant than glass and three times lighter.
A hybrid word meaning "many in composition with carbon atoms." Polycarbonate resins feature many chains of molecules linked to one another, forming a hard thermoplastic with a great resistance to impact and softening. Polycarbonate has been reported to be 50 times stronger than acrylic.
Higher index lenses that are thinner and lighter; the most impact resistant lens.
A plastic material used for glazing.
A thermoplastic polymer resin that is a linear polyester of carbonic acid. Polycarbonate is a transparent, nontoxic, noncorrosive, heat resistant, high impact strength plastic; it is generally stable, but may be subject to attack by strong alkalies and some organic hydrocarbons. It can be molded, extruded, or thermoformed, and is commonly used for numerous services, such as nonbreakable windows, household appliances, tubing, piping, and cartridge filter sumps.
Thermoplastics characterized by high-impact strength, light weight, and flexibility. Used as a shatter-resistant substitute for glass.
