Description:
CapatueTM PPC-LDPE is the name given to microporous LDPE foam for carrier purpose, PPC stands for Porous Polymer Carrier. It is totally utilized the physical foaming technology and process, thus no chemical foaming agents were used and high purity can be achieved. CapatueTM PPC-LDPE offers the polymer processing industry an efficient, easy way to convert liquid or paste-like polymer additives especially for some thermally sensitive additives into dry, free-flowing pellets, needless to extrude.
Microporous structures of CapatueTM PPC-LDPE act like tiny sponges with the ability to absorb several times their own weight. When liquids or meltable solids are mixed with the porous polymer, the micron-size voids in the polymer are filled by capillary absorption. As the mixing is done at room temperature, CapatueTM PPC-LDPE is especially suitable for thermally sensitive additives. When fully loaded with the liquid additive, the system remains dry and free-flowing. In these applications, the large inner surface of the CapatueTM PPC-LDPE, with its accompanying adhesion forces, is utilized in combination with the cell and pore structure of the matrix to retain liquid within the polymer carrier. An additional advantage is the fine dispersion of the additive in the CapatueTM PPC-LDPE structure which insures a homogeneous dispersion of the additive in the final product.
Microporous carrier CapatueTM PPC-LDPE can be used for the production of additive concentrates via physical adsorption of the additive. This product is most effective for the incorporation of liquid additives particularly when accurate dosage and homogeneity of the additive with the base resin is required.

Additive Loading Procedure:
Put CapatueTM PPC-LDPE pellets into a low or medium speed mixer (Henschel mixer, Littleford Lodige mixer, Patterson Kelly V mixer, Sigma mixer, Vertical mixer, etc.) firstly and then add calculated amount of liquid additive (airless spray is strongly recommended.). Then turn on the mixer about 3-10 min. (need to check the temperature of the mixer, not too high (<70 ℃). After turning off, and cool down to room temperature, discharge the liquid adsorbed foamed pellets.

Application:
CapatueTM PPC-LDPE opens a wide range of applications for thermally sensitive PPC-LDPE additives. The reloaded CapatueTM PPC-LDPE is dry and free-flowing which makes them particularly suitable for the masterbatch addition technique. With its great help the additive will get a homogeneous dispersion in the final product.
Organofunctional silanes, maleic anhydride, antioxidants, coupling agents, antimicrobials, fragrances, peroxides, process stabilizers and other performance additives are a few examples of additives that are routinely reloaded into CapatueTM PPC-LDPE matrices. Furthermore, agronomy technology (e.g. pesticide/fertilizer distributor) and cosmetic equipment (e.g. perfume/sent distributor) are also the potential application of our products.
