HOSTANOX P-EPQ P is a highly efficient phosphorus based secondary antioxidant, which reduces the thermo-oxidative degradation of polymers and the development of undesired colour (yellowing) during processing. The main advantages of Hostanox P-EPQ are its high thermal stability and high solubility in polymeric materials as well as its broad compatibility in coating polymers.

HOSTANOX O3 P is a highly efficient phenolic antioxidant with high resistance against hydrolysis.

HOSTANOX O 3 PWD is a highly efficient phenolic antioxidant with high resistance against hydrolysis, providing long term heat stabilization to polyolefins and polyamide especially for applications where the final article comes in contact with extractive media such as water, fat etc.

HOSTANOX OSP 1 MICRO PILLS is a high efficient antioxidant and metal deactivator which prevents the auto-catalytic decomposition of polyolefins. The usage of metal deactivators is mandatory as long as the polyolefin based finished article comes into contact with transition metals, such as Cu, Fe, Ni, Ti, etc.
