Parx Plastics finalises its formulation for Wood Plastic Composite materials
This month Parx Plastics emerged as distinguished wood plastic composite manufacturers and it has concluded its trails and tests proving the successfull addition of the Parx technology to Wood Plastic Composit materials. Product samples, containing a blend of approx. 73% of wood material and 27% of polypropylene, have been produced by plastic injection and the samples have been handed over to an SGS laboratory for ISO22196 antimicrobial performance tests.
Test results by SGS
In the official test report SGS confirms that the samples including the patented Parx technology show an antibacterial performance of Log 7 (approx. 99,99999%) on Escherichia coli (ATCC 8739) and a Log 3.5 (approx. 99,94%) on Staphylococcus aureus (ATCC 6538P). The tests show that even in a product blend, consisting of only 27% plastic and 73% wood, the use of our technology reduces the bacteria count on the surface of the product significantly.

The wood plastic composite market
The global Wood Plastic Composite (WPC) market is expecting significant growth over the coming decade. Recent market studies present CAGR figures for the material/products of around 13.2% reaching an approximate turnover of $9.7 billion by 2025. There is a raising demand for alternatives for plastics, like WPC or other sustainable products and materials. WPC solutions offers possibilities for the recycling of waste materials and gives hugh opportunities for the use of more sustainable products and solutions.
ISO 22196 Measurement of antibacterial activity on plastics
The ISO standard with number 22196:2011 specifies a method of evaluating the antibacterial activity of antibacterial-treated plastics - and other non-porous - surfaces of products. The method compares the bacteria development on the same (shape and size) products manufactured with the same material. Half of the products are manufactured with the antibacterial technology inside and the other half without the antbacterial feature. After an 24 hour incubation period at 35°C, the number of viable bacteria on the surfaces of each sample are counted and compared. The difference defines the antibacterial nature of the treated samples.
