Limitations are that creep properties are generally inferior to rigid PVC, and lower tensile strength. Best creep properties of PVC types. Resistant to acids, alkalis, most organic solvents, oil and grease. Limitations are that it is more difficult to process than PVC due to higher softening point and melt viscosity and it has higher cost. Unaffected by aromatic and aliphatic hydrocarbons, alcohols and esters.
Limitations are that it has higher cost and thermal processing is more difficult.
Terminal boxes and conduit. Protective and foul weather clothing. Tarapaulins, life rafts, hover rafts, conveyer belts. Those vinyl chloride copolymers which are of direct interest to the product designer are used mainly where a rigid polymer with PVC-like service properties is required, but where easier thermal processing is necessary. This type of copolymer is also the material of vinyl sheeting used for thermoforming, which must combine rigidity with easy heat-softening under fabricating conditions.
