The dielectric properties of pure PVC and filled composites were performed to examine characterize the structure polymer composites. At room temperature values relative permittivity, loss factor, ac conductivities calculated as a function frequency it was found that incorporation both micro nano PbO CuO with various wt% matrix resulted in enhanced properties. electrical response micro- or nanoc...

The additives present in polyvinyl chloride (PVC) materials are the major source of organic by-products during PVC degradation. thermal stabilizer and plasticizer main that endow with required properties its processing. However, these two easily migrate when samples obtained by physical mixing PVC. This causes reduction sample efficacy increase formation radiolysis process. In this work, kinds ...

AIMS To investigate the presence of liver lesions and their relation with vinyl chloride monomer (VCM) exposure or other personal risk factors, in workers involved in the production of VCM and polyvinyl chloride (PVC). METHODS A liver ultrasonography examination was conducted in 757 workers, some of whom had long standing service in the production of VCM and PVC. The study involved: assessmen...

BACKGROUND Contact allergy to plastic gloves is rare. Benzisothiazolinone is a biocide that is mainly used in industrial settings. We first suspected delayed-type contact allergy to benzisothiazolinone from polyvinyl chloride (PVC) gloves in 2004. We looked through our medical records from 1991 to 2005 to find similar cases. OBSERVATIONS We found a total of 8 patients who are allergic to benz...

Attempts have been made for the first time to produce a friction material with thermal sensitive modulus by the inclusion of combined plastic/rubber properties of thermoplastic elastomers (TPE) as viscoelastic polymeric materials into the formulation for the purpose of increasing the damping behavior. In order to evaluate the viscoelastic parameters such as loss factor (tan δ) and elastic m...

In this paper, a new method is proposed for the production of MWCNTs/PVC (multi-walled carbon nanotubes/ polyvinyl chloride) nanocomposites. In this method, a spray is used to produce layers of carbon nanotubes within a PVC matrix. Various parameters influence the production of the nanocomposite and its mechanical properties. These parameters are studied separately and the effect of each of par...

S everal recent reports,12 and one in this issue (see page 828), have contributed new observations on pulmonary disease in vinyl chloride (VC ) -and polyvinyl chloride (PVC) -exposed patients. Earlier reports, a few even preceding the identification in 1974 of vinyl chloride as a human carcinogen (with hemangiosarcoma of the liver the marker tumor, but most probably not the only tumor), had cen...

Polyvinyl chloride (PVC) is a very versatile polymer with many applications. Due to the easy incorporation of additives and plasticizers in this resin. The most used plasticizer for PVC dioctyl phthalate (DOP), however its use has been restricted by several organizations because it presents potential toxicity. In way, objective work evaluate thermal, physical dynamic-mechanical characteristics ...
