To test oxo biodegradable plastic products is not an easy job because when its been made, you can not tell any difference from ordinary plastics, so it is important to have standard operation process to prepare for the testing process.

Firstly, we start the small scale trial production of around 100~500KG conventional plastics finished goods, and at the end of this production run, we add oxo biodegradable additives which is specially formulated and designed that tailors to the product application we wish to produce. By doing conventional and degradable samples in the same production run, we will make sure all factors have been controlled, so we have "controlled samples" and "degradable samples".

Secondly, we do some simple sampling process and collect the equivalent amount of samples of each type(usually 500g~1000g) depend on the production type, and then send to lab for testing to see whether the physical properties have been affected and whether the degradation start as planned (ASTM D6954-04)

Finally, usually we need to wait for around 30~60 working days for the aging test (QUV and thermal), so here you go the summary of our test reports. Generally, every application trial takes 3~6 months to develop, and so far we have more than 100 application trials.
