Lustran SAN 31 resin is an injection molding grade of transparent SAN (styrene acrylonitrile) thermoplastic. The base resin used in the Lustran SAN 31 product is in chemical compliance with 21 CFR 181.32 (acrylonitrile copolymers and resins) for use in the manufacture of repeated-use houseware articles as well as FDA modified ISO 10993-1**. It also meets U.S. Pharmacopeia 23 Class 6 test requirements. Lustran SAN 31 has a large molding window and is easy to process. The resin is available in natural (000000) color, crystal (552160) tint, and transparent and opaque custom colors. Lustran SAN 31 resin is a general-purpose grade with a unique balance of cost/performance properties among thermoplastic resins. It is used in a wide variety of applications requiring clarity, heat and chemical resistance, strength and rigidity. Typical applications include beverage tumblers and mugs, blender jars, tableware, dinnerware, cosmetic packaging, instrument lenses, and medical devices. Lustran SAN 31 performs exceptionally well in applications that are subject to demanding environments. Finished products are resistant to heat deformation, scratching, and chemicals, such as foodstuffs, oils, greases, acids, alkalies, and petroleum products. Common solvents, such as MEK and THF, can be used for bonding Lustran SAN 31. Parts molded out of Lustran 31 resin also accept various methods of printing. As with any product, use of Lustran 31 resin in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability. |
