New green chemicals: July

Seems like another record-breaking month in July for the Green Blog’s monthly new green chemicals. Most of them are in the bio-resins category. As always the case with these new products, you be the judge if you think they deserved to be under the umbrella of “green.”

1. Hexion bio-coatings - Hexion Specialty Chemicals has launched Albecor-Bio™, a family of bio-based, low temperature cure powder coatings suitable for use on a wide variety of materials including metals and heat sensitive substrates.

2. Sabic bio-composites - Sabic has introduced a new line of LNP* Thermocomp* specialty compounds that use curauá fiber and wood flour natural reinforcements. Under the line are new LNP Thermocomp PX07444 specialty compound, a polyamide (PA)-6 nylon that is reinforced with up to 20% curauá fiber; and LNP Thermocomp MX07442 specialty compound, a polypropylene (PP) reinforced with 30% wood flour.

3. DSM zero carbon plastic - DSM Engineering Plastics introduced its EcoPaXX™, a bio-based, high performance engineering plastic based on polyamide (PA) 410. Around 70% of the polymer consists of building blocks derived from castor oil.

4. Evonik bio-polyamide - Evonik Industries AG has introduced a group of bio-based polyamides under the VESTAMID® Terra brand. VESTAMID® Terra DS is reportedly a 100% bio-based polyamide 1010 that contains 60% renewable raw materials (I don’t know how it’s 100% biobased…); and VESTAMID® Terra HS is a polyamide 610 that also contains 60% renewable raw materials.

5. Arkema green injection resins - Arkema unveils Rilsan® HT injection resins that offers processing characteristics similar to those of aliphatic high-performance polyamides. The new product contains up to 70% bio-based materials.

6. Bio-Tec bio-foam - Bio-Tec Environmental and the M.H. Stallman Company has started commercial production of the B-Link™ line of biodegradable crosslinked foam, using the degradable additive EcoPure® from Bio-Tec. The foams safely biodegrade once disposed of in a landfill, Bio-Tec said.

7. RTP’s halogen free retardants - RTP Company has expanded its line of halogen-free flame retardant compounds to include nylon and polyester grades. The compounds provide plastics processors and OEMs more options to meet green-initiative requirements, RTP said.

8. Teijin’s bioplastic upgrade - Teijin Limited has upgraded its BIOFRONT bioplastic with substantially improved resistance to hydrolytic degradation in hot and humid conditions. Teijin said the plant-derived bioplastic now offers virtually the same level of durability as polyethylene terephthalate (PET).

9. Huntsman chrome-free dyeHuntsman Textile Effects launched its LANASOL® Blacks range of chrome free dyes for wool and other fine animal fibers. Huntsman also introduced MIRALAN® LTD, a low temperature dyeing auxiliary which facilitates the application of LANASOL® Black dyes for deepest black shades at reduced temperature and shorter dyeing times with minimal fiber damage.
