Viba launches new black PLA masterbatchMasterbatch manufacturer Viba, headquartered in Italy, has added a new
member to its family of PLA masterbatches, the company announced 12
February.
Carbon black masterbatchIn response to demand from the market, Viba has developed a range of
colour concentrate additives or combined masterbatches based on a PLA
carrier material and engineered for different processing technologies.
PLA is gaining increasing acceptance in the market and is seen as a
feasible alternative to various types of conventional plastics, due to
its good balance between physicochemical properties and sustainability.
Obtained from lactide derived from starch fermentation and is some cases
biodegradable., PLA has found application in sectors ranging from such
the automotive, biomedical, and packaging industry, as well as the
growing industry of 3D printing.
The material’s low ductility and toughness require modification for
various applications. Viba’s masterbatches - available as an additive or
colour - can improve the performance of this biopolymer in terms of
impact resistance, mould release, antistatic properties and
anti-blocking.
The latest development is Vibetan PLA Black N0381 - a preparation of
carbon black in a PLA carrier, expressly developed for the colouring of
injection moulded PLA products.
Due to the selected pigments and the special carrier, end products
produced using Vibatan PLA Black N0381 are fully compliant with the UNI
EN 13432 “Packaging - Requirements for packaging, recoverable through
composting and biodegradation” standard, if used at a maximum dosage of
50.0%; the limit permitted in the masterbatch in relation to the
non-biodegradable fillers.
