Apparatus and methods for converting resin into colored finished or semi-finished plastic parts include a process machine having a barrel, a rotatable screw inside the barrel, and a color feed conduit assembly extending into the barrel for passage of liquid color through the color feed conduit assembly into proximity with the screw.

An example method of forming a biodegradable component includes extruding a mixture of biodegradable material and water through a die. The method further includes dividing the extruded mixture to form a plurality of biodegradable pellets. The method further includes forming the plurality of biodegradable pellets into a component. The water acts as a binding agent to bind the plurality of biodegradable pellets to one another.

A method and device for comminuting a thermoplastic polymer, in particular a thermoplastic elastomer, and for producing therefrom pulverulent materials with a predefined grain distribution, includes the following steps: comminuting the thermoplastic polymer, which is provided in lump form, into a starting powder in a comminuting device, and subsequently screening this starting powder at least once until a predefined grain distribution has been attained. A release agent, which reduces the tack and capability for agglomeration formation of the starting powder, is fed into the comminuting device during the comminuting step.

Preparing hybrid-treated plastic particles from waste plastic includes combining waste plastic particles with bio-oil to yield a mixture, irradiating the mixture with microwave radiation to yield oil-treated plastic particles, and contacting the oil-treated plastic particles with carbon-containing nanoparticles to yield hybrid-treated plastic particles. The hybrid-treated plastic particles have a bio-oil modified surface and a coating comprising carbon-containing nanoparticles on the bio-oil modified surface of the plastic particle. In some examples, a diameter of the plastic particle is in a range between 250 m and 750 m, and a thickness of the coating is in a range of 1 nm to 20 nm. A modified binder includes an asphalt binder or a concrete binder and a multiplicity of the treated plastic particles. The modified binder typically includes 5 wt % to 25 wt % of the hybrid-treated plastic particles.

Rubber pellets are coated with an anti-tack material. The anti-tack material may be comprised of a metallic stearate, such as magnesium stearate. The coated rubber pellets are loaded on to a rotational conveyance mechanism that rotates at a speed and radial amount to provide an interaction time between the rubber pellets and the anti-tack material. The coated rubber pellets may then be dried in a centrifuge dryer having a plurality of angled fins extending from a rotational shaft.

The present disclosure provides a composite material layer including a core layer and a shell layer. The core layer includes foamed elastomers. The shell layer encapsulates the core layer and continuously covered surfaces of the foamed elastomers, wherein the shell layer includes a material having light absorption. The melting point of the core layer is higher than the melting point of the shell layer.

According to the invention, the granules are used for producing biodegradable and preferably compostable products and articles of daily use. The present invention also relates to methods for producing the granules according to the invention, as well as methods for producing different products by using the granules according to the invention.

The present invention provides ethylene-vinyl alcohol copolymer composition pellet reduced in coloration. The ethylene-vinyl alcohol copolymer composition pellet of the invention include an ethylene-vinyl alcohol copolymer (A), a polyamide resin (B), and an alkaline earth metal salt (C) and have a yellowness index (YI) value of 10 or less when examined with a spectral color-difference meter by a transmission method.

Provided are a thermally conductive ceramic-polymer composite in which thermoplastic polymers form a matrix, and planar fragments of thermally conductive ceramic or thermally conductive ceramic powder is uniformly dispersed on a grain boundary between thermoplastic polymer particles, thereby forming a thermal pathway, wherein the thermoplastic polymer particles are formed in a faceted shape, and the average size of the planar fragments of thermally conductive ceramic or thermally conductive ceramic powder is smaller than 1/10 of that of the thermoplastic polymer particles, and a method of preparing the same. Accordingly, since dispersion and interfacial affinity of a thermally conductive ceramic filler are maximized, excellent electrical insulation and excellent thermal conductivity can be exhibited even with a small content of the thermally conductive ceramic filler.
