Stronger and lighter than cellulosics. Low starch resistance compared with glass. Flexible grades are not available. Excellent optical clarity and complete transparency equivalent to the best optical glass. Good low temperature characteristics.
Limitations are that it is combustible - self extinguishing grades are available in sheet form only.
Resistant to weak acids and alkalis, aliphatic hydrocarbons and most detergents and cleaning fluids. Low water absorption. Limitations are that it is attacked by strong oxidising agents, chlorinated hydrocarbons, esters, ketones, toluene and lacquer thinners. Susceptible to cracking and crazing if long term stresses exceed 500 psi. Excellent dimensional stability and close dimensional tolerance moldings.
