Acrylic-PVC alloy with high impact strength available. Limitations are recovery from bending or stretching damped compared to rubber. Limitation is that adhesion to many substrates limited in the absence of a primer. Dimensional stability at room temperature for rigid formulations. Almost unlimited range of colors- transparent to opaque according to formulation.
Limitation is the high specific gravity for polymeric material.
Limitations are that flexible grades are most susceptible to staining, chemical and microbiological attack due to presence of plasticisers. Lower coefficient of friction and better abrasive wear resistance than flexible grades. Can be glass fibre-reinforced to give improved strength and stiffness and lower coefficient of thermal expansion. Limitations are that creep properties are generally inferior to rigid PVC, and lower tensile strength. Best creep properties of PVC types.
