Isotactic PMMA is a high-value stereoregular acrylic polymer different from common atactic PMMA, mainly applied in high-end material research and precision manufacturing fields. In optical industry, its regular crystalline structure brings unique refractive index and light transmittance, used for specialty precision optical lens, lab optical fiber and micro-optical component production. Polymer research laboratories adopt it as standard reference material for tacticity test, GPC molecular weight calibration and acrylic polymerization mechanism study. Fine coating industry adds small proportion to high-hardness scratch-resistant transparent coating to enhance coating crystallinity and surface wear resistance. In polymer blending modification, it is compatibilizer for PMMA/PET, PMMA/PP alloy to improve interfacial bonding and finished product mechanical property. Small batch medical grade serves for transparent precision medical accessories requiring stable dimensional change rate, replacing ordinary amorphous PMMA for high precision molding parts. Most goods are supplied to university labs, new material R&D institutions and specialty optical material factories globally.

GHS: No hazard classification for polymer solid, Signal Word: Not required; non-toxic solid polymer raw material. Raw powder dust may cause mild respiratory irritation after long-term inhalation, wear dust mask and nitrile gloves during feeding and crushing processing under ventilated workshop. No skin & eye corrosivity; flush eyes with running water if powder splashes into eyes. Not harmful to aquatic organisms, waste powder belongs to general solid waste instead of hazardous waste. Keep away from strong oxidants and high-temperature open fire to prevent thermal cracking and irritant volatile gas generation at over 230℃. Packed with 25kg paper-plastic composite bag, stored separately from food and chemical reagents. Discard expired products by general plastic waste recycling regulation, no special hazardous waste disposal required.
