IS 4894 covers rigid PVC sheets for industrial and construction applications. Used for chemical tank linings, ventilation ducting, partition walls, and laboratory furniture. Excellent chemical resistance to acids and alkalis at moderate temperatures.
Specification for rigid PVC sheets for general industrial and construction applications covering types, dimensions, mechanical properties, and chemical resistance.
Key Values
Tensile strengthMin 45 MPa
Impact strengthMin 5 kJ/m²
Max operating temp60°C
Practical Notes
! Rigid PVC resists most acids, alkalis, and salts but NOT solvents (acetone, MEK dissolve it).
! Max continuous operating temperature 60°C — above this, PVC softens and loses strength.
! Can be welded (hot air/hot plate) and fabricated into tanks, ducting, and equipment.
