PMMA ZK5BR注塑级透明级高抗冲抗紫外线 亚克力 (CAS No.None)

Product Name:PMMA ZK5BR Acrylic

English Name:PMMA ZK5BR Acrylic

CAS No.:9011-14-7

Aliases:Polymethyl methacrylate, Acrylic, Plexiglass, Acrylic glass

Molecular Formula:(C5H8O2)n

Physical Properties:PMMA ZK5BR is an amorphous transparent thermoplastic with a density of approximately 1.17 g/cm³, a refractive index of 1.49, and a light transmittance of up to 92%. It is hygroscopic and must be dried before processing. It offers excellent impact resistance, UV resistance, dimensional stability, and good mechanical strength, and is rated DIN 4102 B2 for flammability.

Uses:This grade is suitable for automotive applications (signal lamp devices, instrument panels), medical products (blood storage containers), industrial uses (optical discs, light diffusers), and consumer goods (drink cups, stationery). It is also commonly used in products requiring optical clarity and outdoor durability.
