Abstract
Degradable extruded nettings include a plurality of interconnected strands, at least some of the strands being made from a polymeric blend, the polymeric blend including polylactic acid polymer composition, polybutylene adipate terephthalate polymer composition, polylactic acid-polybutylene compatibilizer, and a degradation additive, the degradation additive including a degrader in a carrier resin.
Claims20
A degradable extruded netting, comprising:
- a plurality of interconnected strands, at least some of the strands being made from a polymeric blend, the polymeric blend comprising:
- one or more polylactic acid polymers in an amount of from about 52 wt % to about 60 wt %;
- a polybutylene composition;
- a compatibilizer composition in an amount of from about 0.5 wt % to about 3 wt %;
- and
- a degradation additive in an amount of from about 2 wt % to about 7 wt %.
A polymeric blend composition for a degradable extruded netting, the polymeric blend composition comprising:
- one or more polylactic acid polymers in an amount of from about 52 wt % to about 60 wt %;
- a polybutylene composition;
- a compatibilizer composition in an amount of from about 0.5 wt % to about 3 wt %;
- and
- a degradation additive in an amount of from about 2 wt % to about 7 wt %.
A polymeric blend composition suitable for preparing a degradable extruded netting, the polymeric blend composition comprising:
- one or more polylactic acid polymers in an amount of from about 52 wt % to about 60 wt %;
- a polybutylene composition;
- a compatibilizer composition in an amount of from about 0.5 wt % to about 3 wt %, wherein the compatibilizer composition comprises one or more of polypropyleneglycol diglycidyl ether, epoxidized cottonseed oil (ECSO), maleinized (MCSO) cottonseed oil, or combinations thereof;
- and
- a degradation additive in an amount of from about 2 wt % to about 7 wt %.
