Table 1: Fraunhofer ICT masterbatch study — Formulation differences between the five additive masterbatches, which were subsequently tested for VOC

2007/1/1 · “Development of emission factors for polypropylene processing”, J. Air & Waste Manage. Assoc., V ol ( Yamashita et al. ( , 2007 the VOC emissions of heated

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.

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.

VOCs can cause headaches, nausea, loss of coordination and eye, nose and throat irritation. More serious health effects can include damage to the kidneys, liver or central nervous system, as well as some forms of cancer. Symptoms of VOC exposure can include: Skin irritation or allergic reaction Eye irritation Difficulty breathing Sore throat

Rule Summary The standards limit volatile organic compounds (VOC) emissions from certain process sources in new, modified, and reconstructed affected facilities within polymer manufacturing plants that produce the following basic polymers: polypropylene, polyethylene, polystyrene, and poly (ethylene terephthalate) (PET).

The TVOC (total VOC) emission rates from PVC sheets with DEHP and TPP (soft PVCs) were The polymers were PVC, PE, polypropylene, ethylene-vinyl acetate, 

The uncontrolled emission factors can be used as a basis for the verification of VOC emissions developed from emission source tests, plant site visits, permit applications, etc. These

The present invention is a polypropylene-based resin composition capable of lowering VOC emission by mixing a polypropylene-based block copolymer having a high ethylene content in a reactor and a polypropylene (m-PP) produced using a metallocene catalyst.

Section 2 of this chapter contains a general description of the plastic products manufacturing source category, identifies common emission sources, and contains an overview of available air pollution control technologies. Section 3 of this chapter provides an overview of available

Hazardous compounds emitted during the plastic melting process were analyzed to indicate potential air pollution issues associated with recycle plants for waste plastics. These hazardous compounds might be not only from polymer degradation but also from additives and print ink. To confirm what are emitted from them, melting experiments were conducted (150, 200 and 250°C, in air or N2) and
