Altuglas® SG7
PMMA(亚克力)
阿科玛Altuglas (Arkema)
产品描述
The Altuglas® SG was designed to provide outstanding transmission and water-white clarity for the disposable medical device market. Altuglas® medical resins when it comes to light transmission and high clarity.
These resins also exhibit excellent resistance to discoloration after high-energy sterilization methods.
These impact modified acrylic resins continue to provide impact strength, tensile strength and high modulus, even after high energy sterilization.
Finally, Altuglas® SG resins provide good solvent resistance. Molded medical devices using these resins have good resistance to lipids, moisture, most inorganic aqueous solutions, salinesolutions, mineral oil, and limited exposure to IPA in water. Testing and evaluation must be performed on actual parts and final device for each application.
