Frequently Asked Questions (FAQs)

Q1: Is pre-drying required for SX-304 before injection molding processing?

A1: Yes, drying is recommended. PMMA material is hygroscopic; to avoid defects such as bubbles, silver streaks, or reduced transparency in the finished product, it is recommended to dry the material at 80-90°C for 3-4 hours to reduce the moisture content to below 0.02%.

Q2: What are the core advantages of SX-304 compared to general-purpose PMMA?

A2: As an “Optical Material” grade, SX-304 demonstrates superior performance in purity control, light transmission stability, and anti-yellowing capability. Compared to general PMMA, it ensures extremely high clarity even in thick-walled injection molded parts and has lower internal stress, making it more suitable for precision optical applications.

Q3: Does this product comply with international environmental and compliance certifications?

A3: Yes, Shuangxiang Optics PMMA SX-304 complies with the RoHS directive and contains no harmful heavy metals, while its flame rating reaches the UL 94 HB standard. We can provide relevant test reports and compliance certificates to cooperative clients to support your product certification and terminal market access.
