PMMA

PMMA is amorphous polymer with high rigidity, good mechanical and optical properties – near 92% light transmittance. The best scratch resistance among transparent polymers. Resistance to weather condition, UV stabilised. The disadvantage of this material is relatively low crack resistance, never the less exists three impact modified types. High resistance to non organic substances, lye, acids, salts and its derivatives. Has no hazardous influence on human body. PMMA characterise with beneficial production properties, thermoforming ability. Main application PMMA is due to its optical properties. Suitable for sheets production, car lamp covers, as well as home and urban lightening. Is also used for machinery and appliances elements.

PMMA special types

Grade Characteristics Usage/Application
Altuglas MI 4 Middle impact strength, but the highest thermal stability and scratch resistance among all MI types ElementWhite goods elements – display panels
