TOPAS ® is the trade name of family of cyclic olefin
copolymer (COC) resins developed by Ticona. Topas COCs are made from ethylene and
norbornene and can be tailored to exhibit a wide range of heat deflection
temperatures (HDT) with a practical upper limit of 340°F (170°F).
It is an amorphous transparent copolymer possessing a cyclic olefin structure.
The high purity and absence of ionic content in these materials provide
high insulation resistance and very low dielectric loss. They also have
excellent chemical resistance to aqueous acids and bases and to most polar solvents.
TOPAS is recognized as a resin with optical properties comparable with PMMA
(polymethyl methacrylate, acrylic resin), superior heat resistance to PC (polycarbonate),
and superior dimensional stability to both PMMA and PC.
Topas COCs have a very high moisture barrier, low water
absorption, good resistance to hydrolysis and chemical media, and low
density. In addition, they typically offer high transparency extending
into the UV range, low birefringence, adjustable heat deflection temperature
and high rigidity.
Examples of applications for Topas ® COC plastics
include films for pharmaceutical and personal health care blister packs, food
packaging, medical syringes and vials, diagnostic articles, optical lenses, light
guides, and optical sensors. NOTE: All Topas grades are approved for food contact
in Europe (EU Plastics Directive 2002/72/EC) and the USA (FDA 21CFR § 177.1520 "Olefin polymers").
AVAILABLE TOPAS COC GRADES
The following Topas COC grades are available in machinable pre-molded sheet and rod forms from Boedeker Plastics:
NOTE: We do not sell resin, pellets or powders.
Topas 8007S-04
has high moisture barrier properties which make it especially suitable for healthcare
applications and pharmaceutical packaging. It has the lowest moisture permeability
and lowest heat deflection temperature (167°F / 75°C) of all Topas grades.
Topas 8007X10
was developed with superior transparency in the UltraViolet (UV) range of the
electromagnetic spectrum. As a result, it is most suitable for UV transparent
applications such as DNA analytical micro titer plates or cuvettes.
Topas TKX-0001
is specifically designed for use in optical components or other applications where
very high surface quality is desired. Its mechanical properties are somewhat higher
than other Topas grades, though its temperature capabilities are in the mid-range
with a heat deflection temperature of 260°F (127°C).
Topas 6015S-04
has good temperature capability with a heat deflection temperature of
320°F (160°C). It is most suitable for products requiring dimensional stability
due to repeated sterilization or temperature cycles, such as medical trays or instruments.
Topas 6017S-04
has the highest heat deflection temperature (338°F / 170°C) of all Topas grades.
It also has excellent dielectric properties which are stable into the GHz frequency
range, making it suitable for electrical and electronic applications.
