Colorants for Plastic Pellets


Black	Blue	Dark Gray

Gray	Light Blue	White

Yellow	Green	Dark Red

Orange	Red

Add color when making plastic parts. Also called masterbatches, these colorants contain a base plastic that works with a variety of plastic types—from general purpose polypropylene to tough ABS. This means you don’t need to stock up on colorants for each type. Mix them in with your pellets before melting. To get a rich color for most plastic, you need only 1-2% of colorant in your batch, since they’re concentrated.

Plastic Pellets

Use them with injection molders, 3D printers, and other molding equipment.

Impact Resistant—Absorbing impact without cracking or breaking, these plastic pellets are molded into parts that endure bumps, scrapes, and falls.

Moisture Resistant—These pellets resist swelling when exposed to water, making them suitable for use in wet environments. Melt and mold them into desired shapes.

Wear Resistant—With a low coefficient of friction, these pellets won't wear away from abrasion that’s often caused by contact with moving parts. Melt and mold them into desired shapes. They handle high temperatures without losing their mechanical properties.

HoPP—HoPP pellets are harder than HDPE pellets, so they won't scratch as easily. HoPP has greater tensile strength than CoPP.

CoPP—CoPP pellets are harder than HDPE pellets, so they won't scratch as easily. CoPP has better impact resistance than HoPP. It resists impact even at low temperatures.

HDPE—Choose HDPE pellets for general-purpose applications such as protoyping.

HIPS—HIPS pellets are easy to thermoform, so they’re good for signs, packaging, and other light duty applications.

ABS—ABS pellets are easy to thermoform, have good impact resistance at low temperatures, and have more chemical resistance than those made of HIPS or polycarbonate. They’re also more impact resistant than HIPS pellets. Use them to make storage cases, tote trays, equipment housings, and protective gear.

Nylon—Nylon pellets have good wear resistance, as well as chemical resistance against fuels and hydrocarbons. They will expand and contract when exposed to moisture and temperature changes.

Polycarbonate—Polycarbonate pellets handle higher temperatures than any of these other materials, but they’re more difficult to thermoform. Clear in color and a lightweight alternative to glass, they’re often used to make windows, machine guards, and instrument covers.

PVDF—PVDF pellets are flexible, weather resistant, and have the most chemical resistance of all these materials. PVDF is also known as Kynar.

PEEK—PEEK pellets stand up to acids, alkalis, and oils. They are often used as a lightweight alternative for metal parts in chemical-processing applications. They will expand when exposed to moisture.

Foaming Agents for Plastic Molding Machines

Commonly used in molding applications such as injection molding and extrusion, these foaming agents reduce weight, warpage, and sinks in finished parts. Mix them into resin as 0.5-1.5% of the total mixture—by decreasing the amount of resin needed to make a part, they help reduce costs. They also lower the melt viscosity of resin so that it can be processed at low temperatures, which reduces cooling times, cycle times, and the risk of heat degradation. These foaming agents are compatible with most plastic and rubber resins.

Microfine Cell—Microfine cell agents produce smaller bubbles and a tighter cell structure than other foaming agents. They improve the appearance of your final product and keep its mechanical properties consistent throughout. They’re often used to create parts that have thin walls.

Fine Cell—Fine cell agents produce more gas than microfine agents. Use them to ensure uniform foaming when molding bigger parts.

310° F Activation Temperature and 325° F Activation Temperature—Agents with a 310° F or 325° F activation temperature are for use with low-melt-temperature resins such as polyolefins, polystyrenes, and thermoplastic elastomers.

400° F Activation Temperature—Agents with a 400° F activation temperature are for use with high-melt-temperature resins such as polycarbonates and polyamides.

FDA Compliant 21 CFR 174.5—All are FDA compliant for direct contact with food.
