Under the general term GreenLine, EMS-GRIVORY markets a wide range of bio-based polyamides which are manufactured partially or wholly from renewable raw materials. The "GreenLine" series is made up of products from the families:
which provide a wide spectrum of special properties from very flexible to extremely rigid, from high heat or hydrolysis resistant to perfectly transparent.
The primary objective of EMS-GRIVORY with GreenLine is to offer customers products based on renewable raw materials, having excellent properties and allowing a proven contribution towards reduction of environmental impact. From a technical point of view, GreenLine products are in no way inferior to crude-oil based polyamides.
By using monomers obtained through chemical processes from the renewable raw material castor oil, the environmental impact of GreenLine products is significantly improved from a “cradle to gate” point of view compared to crude-oil based polyamides. The total emission of climate-damaging gases during the whole manufacturing process of the polymer and its precursors can be reduced by up to ¾ depending on the product.
Despite the use of renewable raw materials, GreenLine products are not biologically degradable polymers. Their durability is comparable to that of crude-oil based polyamides.
The bio content of GreenLine products varies from about 50 up to 99% depending on the type of polymer, when determined according to ASTM D 6866-12 and expressed in percentage of total carbon.
