6. Features: 

A.          Degradability: A certain time after the products exposed in the sunshine, the photo-sensitizer absorbs the ultraviolet radiation and degrades and emits activation free radical that makes the polymer molecular weight lessened and the products embrittled quickly, and then the products crack into minor pieces, powder, innoxious molecule at last.

B.          Processibility: Conventional facilities can be used, no need to change the technology.

C.          Products properties: Good transparency, no influence to products strength.

D.          Ideal additive: No stimulation, innoxious, good plasticizing, regular granule.

7. Applications: Suitable for making kinds of films, sheets, and injection mould and foaming products.

8. Percentage to be added: For film, 1%-5% recommended; for injection, 1-8% recommended.

9. Processing instruction: Good processibility, no change of processing facilities.
