Intertek has been accredited for material testing by automotive market leading OEM (s) and works with customers on Automotive VOC issues to minimize problems before they arise in the field, providing Automotive VOC testing and aldehyde-ketone emission testing for materials and products. Gaseous VOC constituents emitted from test samples are

Changes in the molecular weight of the copolymer polypropylene were analyzed via the Chain Scission Distribution Function (CSDF) procedure and 

The VOC's produced are a mixture of the following: Aliphatic hydrocarbons: alkane, alkene. Aromatic hydrocarbons: benzene, toluene, xylene. Aldehyde: formaldehyde. Polycyclic aromatic hydrocarbons: benzo (a)pyrene. Some materials have other specific groups e.g. PVC polymers generate HCl, 2 component epoxy polymers yield amines and PET generates

4/1 · Table 1 summarizes the emissions of individual VOCs from all carpets at the various chambers after 24 and 72 h.Benzene and toluene were found to be released from all carpets in concentrations varying from ND (not detected) to 4.6 μg m −3 (Cp-2/24 h/0.28 m 3), and from ND to 8.6 μg m −3 (Cp-4/24 h/0.02 m 3), respectively.

the differences in the VOC emission characteristics from and waste plastics. plastics, including low- density polyethylene (LDPE), polypropylene (PP), and polystyrene (PS), were used in the melting experiments. Waste plastic pellets provided by a recycling facility were used for comparison. Dependence of the VOC emission

The VOC's included aliphatic (ethane, ethylene, propylene) and oxygenated compounds (aldehydes, ketones and carboxylic acids). The most common components found were particulates and VOC's, meanwhile oxygenated compounds appeared in lower concentrations, with emission rates directly proportional to the extrusion temperature.

5.5.2 Overall VOC capture and control efficiency of VOC emission control system, 5.5.3 Material VOC content at relevant manufacturing points. The amount of VOC in the material shall be determined using the test method in Section 6.2.4, or other method approved by the APCO and EPA. 5.5.4 VOC emission calculation formula which will be used to

Emission factors for selected volatile organic compounds and particulate emissions were developed during extrusion of commercial grades of propylene 

This work could provide scientific knowledge on both the accurate traceability of VOCs emissions and new technology for development of low-VOCs PP composites for vehicle. molecular structure 1. Introduction Polypropylene (PP), due to the excellent cost-performance ratio and material versatile properties superior to those of other

The loading particulate emissions are controlled by fabric filters guaranteed to reduce the particulate emissions to less than 0.01 grain/scf. The vent gas to the control device during loading is expected to be a maximum of 6800 scfm. Hourly particulate emissions are determined to be: lb hr grain lb scf grain hr scf
