Polyvinyl chloride floor tile

DEHP levels in indoor air might be higher due to stow volatilization from plastic products (EPA 1981 Warns 1987). As noted in Section 6.2.1, Cadogan et al. (1994) reported that an indoor overall emission rate of 2.3x10 4 mg/second-m2 at 25 °C has been calculated for all phthalate plasticizers in products such as wall coverings, flooring, upholstery, and wire insulation. The air from rooms recently covered with polyvinyl chloride (PVC) tiles contained 0.15 0.26 mg/m3 (150,000 260,000 ng/m3) phthalate esters (EPA 1981). Indoor air levels in rooms with new flooring couldbe about 0.2 0.3 mg/m3 (Warns 1987). 

Polyvinyl chloride is processed into a number of forms by including additives. Additives are used to vary the properties of PVC so that it can be made soft and flexible or hard and rigid. Additives are also used to inhibit decomposition as a result of exposure to sunlight, ozone, and chemicals. Plasticizers are the primary additive included in PVC materials. Di(2-ethylhexyl) phthalate (DEHP) and a host of other phthalates are the most common plasticizers. Plasticizers impart flexibility, thermal stability, strength, and resilience to PVC compounds. PVCs without plasticizers are classified as UPVC the letters stand for unplasticized polyvinyl chloride. UPVC is rigid and used for conduit, containers, gutters, and floor tiles. Other common PVC additives are biocides, lubricants, and pigments.

Polyvinyl chloride (PVC) probably the most versatile thermoplastic material, being available in many forms over a wide range of hardness and flexibility. Varying the use of plasticisers in PVC can make it more suitable for numerous applications. Uses include film-like coatings, wall and floor tiles, domestic appliance components, dolls, gramophone records, gloves, hoses, etc. 

Wood flours are used as a reinforcing material for thermoplastics, thermosets, and elastomers. Some wood fiber-thermoplastic materials can be recycled repeatedly with no significant change in performance. Commercially wood flours have long been used in polyvinyl chloride (PVC) compounds for flooring tile. The main applications for wood-plastic compounds are decking, consumer goods, and housewares.
