Topas ® 8007S-04
Cyclic Olefin Copolymer (COC)
Specifications
GENERAL DESCRIPTION
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").
TOPAS 8007S-04 GRADE
Topas ® 8007S-04 Cyclic Olefin Copolymer
(COC) 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
