Key Features
PVC-U Film (unplasticized polyvinyl chloride) is a rigid, chemically resistant thermoplastic film containing no plasticizer additives, combining inherent flame retardancy with good chemical resistance:
Highest Inherent Flame Retardancy of Any Commodity Plastic Film
Limiting oxygen index of 45–47% and V0 flammability classification without flame retardant additives give PVC-U the best inherent flame retardancy of any commodity plastic film. No additive treatment is required to achieve this performance, which cannot be matched by polyolefin or polyester films.
Good Chemical Resistance
Good resistance to acids, alkalis, oils, and aqueous media supports chemical plant lining, duct cladding, and agricultural film applications where chemical exposure is a service requirement.
Good Rigidity and Stiffness
Tensile strength of 40–60 MPa and tensile modulus of 2.5–4.0 GPa, without any plasticizer additions, qualify PVC-U for blister pack base webs, protective overlaminates, and rigid film applications where dimensional stability is required.
Good Electrical Insulation
Dielectric constant of 2.8–3.1 and good electrical insulation properties support electrical insulation tape, cable wrapping, and general electrical insulation film applications.
No Plasticizer Migration
The absence of plasticizer additives eliminates the plasticizer migration concern that affects plasticized PVC-P grades in food contact and pharmaceutical packaging applications, providing a more chemically stable film for regulatory-sensitive uses.
Industrial Applications
Unplasticized PVC Film is used across chemical processing, medical device packaging, electrical insulation, and agriculture wherever flame retardancy without additives, chemical resistance, and rigidity must be combined:
- ✦ Chemical Plant Duct and Tank Lining
- Used for chemical plant duct and tank lining where good resistance to acids, alkalis, and aqueous media and the rigid film structure provide long-term barrier integrity in chemical service environments.
- ✦ Medical Device Packaging and Blister Pack Base Webs
- Applied for medical device packaging and blister pack base webs where rigidity, thermoformability, and regulatory compliance for pharmaceutical contact support reliable sterile barrier packaging.
- ✦ Electrical Insulation Tape and Cable Wrapping
- Used as electrical insulation tape and cable wrapping where good electrical insulation and V0 flammability classification provide reliable, flame-retardant cable protection.
- ✦ Protective Signage Overlaminates
- Applied as protective overlaminates for exterior signage and graphics where chemical resistance, rigidity, and UV stability in appropriate stabilized grades support long-term protective overlay performance.
- ✦ Agricultural Tunnelling and Cladding
- Used in agricultural tunnelling and cladding applications where rigidity, chemical resistance, and flame retardancy are simultaneously required alongside UV stability in appropriate stabilized grades.
- ✦ Barrier Property, Plasticizer Migration and Polymer Ageing Research
- Used for barrier property characterization studies, investigation of plasticizer migration from adjacent PVC-P materials into food or pharmaceutical contact layers, polymer ageing and degradation studies under UV and thermal exposure, and as a reference substrate for adhesive and coating development.
