Product Description

Description:

Aria Couple 1431 ® polymer resinis a maleic anhydride functionalized homopolypropylene produced by reactive extrusion. It has been primarily designed to act as a coupling agent inbiodegradable polyolefin compounds. This grade is designed to function as acoupling agent between fillers such as starch and polyolefin.

Technical specification:

Achieve suitable dispersion and distribution of starch in polymer matrix

Improve physical and mechanical properties of biodegradable containers

Eliminate output variation

Achieve dimensional stability and increase smooth surface of final products.
