Impact-resistant PMMA- Transparent high impact-resistant Grade
In applications that require durability when breakages may occurs due to external impacts or in the course of processing, it is necessary to improve the impact strength. The low impact strength, which is a disadvantage of general PMMA, needs to be overcome in the case of these applications. LX MMA's transparent impact-resistant PMMA uses an acrylic impact modifier to improve its impact resistance while ensuring the weather resistance does not deteriorate. It is applied to areas where greater impact strength is required, such as the exteriors of home appliances, mobile phone windows, various sheets for buildings, and lighting profiles.
