Bioplastics are plastics made from renewable resources or plastics that are fully biodegradable and compostable. More and more of these materials are being developed to help solve problems with landfill and plastic pollution in our water systems. There are many options for people interested in bioplastics, but we’ve had a look at a few that we found interesting.

These plastics are separated into five different series, highlighted below. From super low-viscosity, fast-setting resins to water-clear options, almost any color, size, shape, weight and appearance can be achieved by using these systems. Utilize available accessories to help achieve the desired look and feel.

Kast Series products are two-part, room-temperature curing (RTV) systems designed for use in a variety of applications including foundry, special effects, prototyping, vacuum and thermo-forming, and many other industrial and commercial applications.

One variety is designed to replace PET in things like clamshell packaging, bottles, and blister packs, while the other is designed for injection molding. It can be both recycled or biodegraded.

Poly 15-Series feature pourable, room-temperature curing resins that mimic the density of thermoplastics (e.g., ABS) or wood, while other options are great options for constructing lightweight mold shells, composites, or master models.

Polytek's two-part, room-temperature curing polyurethane plastics are available in varieties that can be poured, brushed or sprayed to create castings with unlimited versatility.

EasyFlo plastics are incredibly versatile and work well for countless commercial, industrial, hobby, craft, prop and display projects.

It’s main use so far has been in producing Biopallets, a replacement for wooden pallets that decompose much faster, reducing the hard waste that is produced.  As a timber replacement it will be interesting to see whether this technology takes off in different applications such as housing and furniture.

Grabio is a resin made from starch, to reduce dependence on petroleum and trees. When the material is burned, it releases no toxic gases, and generates less CO2 than traditional plastics.Grabio has been used to make a high tensile strength film, designed for use in supermarket and garbage bags. It is similar in properties to LDPE and can be used in the same applications such as bottles, trays and toys.

Biofiba is a biodegradable simulated timber, made in Australia from industrial hemp. It has been designed to replace plastics, polystyrene, cardboard and timber in the export packaging industry.

Kast products were developed to provide high moisture resistance, improved filler suspension, easier premixing of the components, and minimal shrinkage.

EasyFlo Series products are easy-to-use, mercury-free polyurethane resins with simple, 1A:1B mix ratios by volume. These super low-viscosity liquids make for perfect detail penetration and bubble-free castings without the need for vacuum or pressure techniques. Rapid demold times make EasyFlo products ideal for high-volume, fast-cast applications. This series includes options that can be poured, rotocast and sprayed.

Poly 15-Series plastics are versatile systems that are used in countless commercial, industrial, tooling, prototyping, craft, prop and master making applications. These plastics offer an up-front cost savings compared to the expensive tooling costs associated with metal molds required for injection-molded thermoplastic parts.

Poly-Optic® 14-Series & 17-Series plastics are specifically designed for applications where optical clarity is a must. Castings will be water-clear; however, PolyColor Dyes can be added to obtain clear, colored castings. In addition, Poly-Optic systems can be filled with metal, marble and many other fine powders to achieve myriad effects. Poly-Optic® 17-Series products are mercury-free formulas.

As product designers, we know how important it is for people to choose the right materials. As well as choosing something appropriate, people often have other concerns – sourcing local materials from Melbourne or finding a sustainable option. Bioplastics are one option for people concerned about their environmental impact.

Poly-Optic resins are the plastics of choice for mimicking glass and ice-like features and are widely used to create stunning prototypes (lenses, bottles, containers), as well as unique art, medical models, sculpture and display items.

Polysole is a bioplastic produced by Solegear, produced without any hazardous chemicals it is made from Polylactic Acid (PLA), derived from plants. It comes in two varieties, each designed for specific uses.]

NOTES: Vacuum and/or pressure casting techniques are recommended for these products. These formulas are not recommended for long-term exterior use. They can be sealed with a UV-stable clear coat and/or UV Additive can be added to the liquid mixture for longer outdoor use.

Poly Plasti-Flex is a low-density, slightly flexible plastic that can be used to make decorative trim, props or impact resistant parts.
