Effects of Acids and Alkalis
:
 Good resistance to most mineral acids. Dissolve with partial decomposition in concentrated solutions of sulphuric acids. Good resistance to weak alkalis. Moderate resistance to strong alkalis at room temperature. Disintegrate in strong alkalis at boil.
Effects of Mildew, Aging, Sunlight & Abrasion
:
 Not weakened by mildew, excellent resistance to aging and abrasion. Prolonged exposure to sunlight causes some strength loss.
