Classification of plastics

Plastics are required in almost all areas of life and are increasingly replacing conventional materials.

According to the difference of molecular structure, plastics are divided into Thermoplastic (linear polymer) and Thermosetting (mesh polymer).

Common thermoplastic materials include PVC, PE (LLDPE, LDPE, HDPE), PP, PS, PC, PA, ABS, PET & PMMA.

Common thermoset plastic materials include Epoxy (EP), Polyimides, Phenolics (PF), Unsaturated polyester (UP) and Silicone plastics, many of which are important in composites.

Classification of Plastic molding process

Plastic molding process includes: injection molding, blow molding, extrusion molding, Drawing, compression molding, Laminated molding, Casting molding, etc.

Raws of plastics: Masterbatch

There are 3 main types of masterbatch: Color masterbatch, filler masterbatch & Functional masterbatch.

The composition of masterbatch includes: Pigment or dyes, carrier (resin & filler) and additives.

Special Effect Color Masterbatch

For general colorful plastics, regular organic pigment or inorganic pigment are needed. But some plastic products need special color effect, for instance, makeup containers, shampoo containers, food and drug containers, hoses, daily plastic products, Toys, buttons, sandals, furniture plastic decorations, etc. For these special effect requirements, you could choose pearlescent pigment, glitter powder, aluminum pigment, fluorescent pigment, glow-in-the-dark pigment, thermochromic pigment, photochromic pigment, chameleon pigment etc. You can find all of these special effect pigment from iSuoChem. Special effect pigment gives the unique effect and adds the value of plastic.

Introduction of special pigment for plastics

1. Pearl Pigment for plastics

Pearl pigment has stable chemical property and it doesn’t discolor during resin processing, neither precipitate, bloom nor melt in the resin system. Most of clients are worried about the safety of metallic pigment in plastic processing. For example, silver powder (aluminum powder) and gold powder (zinc-copper alloy powder) are often used for plastics, in the process of mixing, kneading, extrusion and granulation of plastic resin and pigment, the risk of fire and explosion is noteworthy. iSuoChem pearl pigment is non-metallic pigment and doesn’t react with plastic additives. So it is absolutely safe. At the same time, pearl pigment will not cause fading and graying of plastic particles, but can also produce bright metallic luster effect and pearl effect.

2. Glitter Powder for plastics

For Plastic application, the heat resistance is very important. We recommend aluminium based glitter powder for injection molding and it gives beautiful sparking effect for your plastics.

3. Luminous Pigment for plastics

Luminous Pigment can make your plastics glow in the dark. Contact with iSuoChem team, you can get specific direction for how to adopt luminous pigment to your plastics.

Options of Plastic Additives

iSuoChem can supply Erucamide, Oleamide, Behenamide, UV stabilizer & UV absorber for your plastics.
