本文件已被宣布为“稳定”，不再接受货币定期审查。用户负责验证参考资料和持续适用性或技术要求。新技术可能存在。本规范涵盖一种类型的甲基丙烯酸甲酯，其形式为挤压成型、压缩成型和注射成型。这些产品通常用于需要良好尺寸稳定性、高度光学清晰度和良好户外耐候性的零件，但使用不限于此类应用。

This document has been declared "Stabilized" and will no longer be subjected to periodic reviews for currency. Users are responsible for verifying references and continued suitability or technical requirements. New technology may exist.This specification covers one type of methyl methacrylate in the form of extrusions, compression moldings, and injection moldings. These products have been used typically for parts requiring good dimensional stability, a high degree of optical clarity, and good resistance to outdoor weathering, but usage is not limited to such applications.
