Lapol® 108 renewable bioplasticizer and melt viscosity enhancer enables polymers to be functional in standard processes such as injection molding, extrusion coating, thermoforming and cast films. It promotes toughness and flexibility without sacrificing modulus while minimizing glass transition temperature reduction. It maintains high melt viscosity when processing polylactic acid (PLA) to enable high concentrations of inorganic mineral in compounds.
Lapol® HDT is a renewable additive for PLA which drastically increases the melting point of PLA to enable the compound to be useful in high temperature applications such as food service, automotive, credit card stock, electronic devices and summertime transit. By enabling high temperature PLA, many other applicatons can now use PLA and high temperature summer transit of PLA products will not longer stick or warp with the use of Lapol® HDT.
Characteristics Affordability Lapol® 108 resin is less expensive than other plasticizers used for increasing the toughness, flexibility and processabilty of polylactic acid (PLA) and other polymers. Since Lapol® 108 is miscible with PLA, no additional costly compatiblizing additives are needed when using Lapol® 108, thereby reducing the overall cost of improving toughness, flexibility and increasing elongation. Renewability & Sustainability Lapol® 108 bioplasticizer resin is predominantly plant derived.
Biodegradability & Compostability Lapol® 108 bioplasticizer resin is compostable and is biodegradable under composting conditions in about 35 days based on the ASTM D6400, EN 13432 & ISO 17088 standards.
Flexibility & Toughness Lapol® 108 bioplasticizer resin increases flexibilty and toughness with little sacrifice in modulus. When Lapol® 108 is added at 5%-10% in PLA an extruded sheet can be folded over without cracking or the brittleness typical of neat PLA .
Maintains PLA Melt Viscosity In order to compound a high mineral content into PLA, it is often necessary to increase the processing temperature to get a homogeneous and thoroughly mixed compound, this results is a very low melt viscosity which induces processing difficulty. When Lapol® 108 bioplasticizer resin is compounded into PLA resins, at levels as low as 5%, it enables very high mineral content loading without the loss of melt viscosity.
Clarity Lapol® 108 bioplasticizer resin is miscible with PLA and only minimally affects the clarity of PLA. Haze does develop with higher concentrations, but one can still see through the plastic. Many applications will need about 5%-10% concentration of Lapol® 108 and therefore, only a little haze should be expected.
Compatibility Lapol® 108 bioplasticizer is compatible and miscible with PLA up to 20%. Unlike compounding with 100% petroleum-based aliphatic/aromatic copolyesters (AAC), there is no need to add additional costly compatibilizers or processing aids for improved compatibilization. Since PLA and Lapol® are "like polymers" they are very compatible in compounding so there is no die swell out of the compounder, a common phenomenon with petroleum based plasticizers.
Availability Lapol® 108 resin is made in America in top production facilities with virtually no limitation on production capacity.
"Heat-ability" NEW LAPOL® HDT - NOW AVAILABLE! The new Lapol® HDT additive for increasing the heat deflection temperature of PLA is now available; we recommend using our pre-compounded injection molding and thermoforming grade resins for your evaluation of the resin. With Lapol® HDT additive, PLA is now ready where higher temperature performance is needed such as > 100° C (212 °F), it will not warp or distort in hot weather transit or in use for items such as hot coffee, soups or higher temperature durable plastics applications. Reduced cycle times of up to 40% have been demonstrated which can offset the HDT additive costs. Click here to Download the Lapol HDT Technical Bulletin.
