Additives: Stabilisers, plasticisers and others - PVC 21 Sep 2015 There are several different types of additives for pvc. “Stabilisers” enhance the heat stability in moulding and heating operations. “Plasticisers” confer flexibility and certain other product qualities. “antioxidants” and “UV absorbents” prevent quality deterioration during use of plastic products, and “lubricants”, “pigments” and “fillers” give additional properties to plastic products. After addition of these various additives, pvc is moulded and fabricated into durable products 

PVC sustainability - Sustainability - PVC 21 Sep 2015 pvc is a material well-suited to recycling. It has the longest history of recycling among plastics, and it is most advanced in mechanical recycling. For example, in Japan about 68% of end-of-life agricultural films (agro-films) was recycled in 2005 and used for flooring, etc. In Europe, more than 260,000 tons of post-consumer products were recycled in 2011 through industry-sponsored schemes. All materials, and pvc is no exception, have sustainability issues, arising 

Post-Consumer PVC in Building Materials - Healthy Building Network 2 Apr 2015 The recycling industry and building product manufacturers have made significant strides toward the vision of a closed loop material system, whereby materials produced today become the raw materials for their products in the future. Contamination of feedstocks with chemicals of concern, however, is reducing feedstock value, impeding growth of recycling rates and potentially endangering human health. The white paper assesses the extent of these challenges based 

Resilient Flooring & Chemical Hazards - Healthy Building Network 13 Apr 2009 use of renewable feedstock materials and recycling or improved end of life management. While no ideal “green” material currently exists for health care flooring options, Resilient flooring & Chemi- cal Hazards: A Comparative Analysis of Vinyl and Other. Alternatives for Health Care illustrates the existence of a range of alternative materials which are preferable to sheet and tile products made with pvc – posing fewer chemical hazards in their current formulations.

Adverse Health Effects of Plastics Ecology Center Examples of plastics contaminating food have been reported with most plastic types, including Styrene from polystyrene, plasticizers from pvc, antioxidants from polyethylene, and Acetaldehyde from PET. Phthalates (DEHP, DINP, and others), Softened vinyl products manufactured with phthalates include vinyl clothing, emulsion paint, footwear, printing inks, non-mouthing toys and children's products, product packaging and food wrap, vinyl flooring, blood bags and tubing, 

Polyvinyl chloride - Wikipedia Liquid mixed metal stabilisers are used in several pvc flexible applications such as calendered films, extruded profiles, injection moulded soles and footwear, extruded hoses and plastisols where pvc paste is spread on to a backing (flooring, wall covering, artificial leather). Liquid mixed metal stabiliser systems are primarily based on barium, zinc and calcium carboxylates. In general liquid mixed metals like BaZn, CaZn require the addition of co-stabilisers, antioxidants and 

1 Chapter 4 ADDITIVES FOR RECYCLING AND - ICPE Most manufacturers have added to their stabilizers a suitable range formulations for recycled material. Akcros has developed calsium/zinc stabilizers containing a number of co-stabilizers in its Interlite range for pvc flooring and profile recycling. Ciba Giegy's. Irganox 245 antioxidant cuts to 25% yellowing index of recycled PS yoghurt pots during ageing. Irgastab CZ 2000 calsium/zinc stabilizer at 2% addition reduces the yellow index of pvc window profiles.

For recycling they really need to be sorted into individual polymer types such as polythene, polystyrene or polyvinyl chloride, otherwise they have no strength if remoulded and may literally fall apart. This is an area in which 

Calcium - Zinc stabilisers - PVC 21 Sep 2015 These materials are generally based on metal carboxylates and will sometimes incorporate other elements to boost performance such as aluminium or magnesium. Because the heat stability in some applications may require some enhancement when using calcium/zinc, organic co-stabilisers will also often be added to this type of formulation. These materials include polyols, epoxydised soya bean oil, antioxidants and organic phosphites. Properties and Applications

Heath, Ohio, additives help preserve quality in HDPE recycling. “Using antioxidants is one way we differentiate our resins from our . By contrast, pvc reprocessing doesn't appear to create special stabi- likation or additives needs, according to suppliers. “Most compounds contain enough additives for two or three cycles,” says Peggy Holsopple, techni- cal service leader at 

VinylPlus - Why recycle? Using recycled pvc reduces emissions and landfill. VinylPlus has set a target of 800,000 tonnes of pvc to be recycled every year by 2020. In 2016, nearly 570,000 tonnes of pvc were recycled in Europe. The majority of recycled pvc comes from window profiles and other related building products. pvc Recycled 2016. There are currently more than 100 operations in Europe which recycle pvc pipes, profiles, flooring, coated fabrics and membranes. The European pvc industry is
