Description
GreenLine
Bio-based polyamides
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:
Grilamid 1S (PA1010)
Grilamid 2S (PA610)
Grilamid TR (amorphous transparent PA)
Grivory HT (polyphthalamide)
which provide a wide spectrum of special properties from very flexible to extremely rigid, from high heat or hydrolysis resistant to perfectly transparent.
Renewable raw materials
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.
GreenLine Products
Grilamid 1S PA1010 and Grilamid 2S PA610
Key features:
- high to very high bio-content
- properties similar to those of PA12
- low moisture absorption

- good UV and chemical resistance
- low density
- for injection and extrusion processing
- good adhesion of Grilamid 1S PA1010 to bio-based Grilamid BTR grades in overmoulding or sandwich moulding processes.
Grilamid TR, amorphous transparent polyamide
Key features:
- high bio-content
- excellent transparency and natural colour
- very good chemical resistance compared to most other amorphous thermoplastics
- high gloss and good scratch resistance
- low density
- good adhesion to Grilamid 1S PA1010
Grilamid TR: Transparent polyamide for the most exacting requirements
Grivory HT3 PPA (Polyphthalamid)
Key features:
- high bio-content
- very low moisture absorption compared to other PPAs
- high dimensional stability
