Plexiglas® HT121
PMMA(亚克力)
阿科玛Altuglas (Arkema)
产品描述
Plexiglas® HT121 is a thermoplastic acrylic resin formulated for injection molding applications. This grade has the highest heat resistance of all the Plexiglas® grades. Plexiglas® HT121 has excellent weatherability and optical properties allowing it to excel in applications requiring outdoor stability, high quality surface appearance and/or precision optics. It has excellent resistance to many chemicals including solutions of inorganic acids, alkalis and aliphatic hydrocarbons such as VM&P naphtha and heptane. Additionally, it is virtually unaffected by a wide range of commercial products including many beverages, foodstuffs, detergent solutions and cleaners.
