Impact-Resistant Plastic Pellets

Absorbing impact without cracking or breaking, these plastic pellets are molded into parts that endure bumps, scrapes, and falls. Use them with injection molders, 3D printers, and other molding equipment.

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

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.

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

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.

Moisture-Resistant Plastic Pellets

These pellets resist swelling when exposed to water, making them suitable for use in wet environments. Melt and mold them into desired shapes. Pellets are made from virgin resins and are compatible with various types of molding equipment such as injection molders and 3D printers.

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

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

Wear-Resistant Plastic Pellets

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. All of these pellets are made from virgin resins and are compatible with various types of molding equipment, such as injection molders or 3D printers. They handle high temperatures without losing their mechanical properties.

PEEK and PVDF pellets stand up to acids, alkalis, and oils. PEEK pellets are often used as a lightweight alternative for metal parts in chemical-processing applications. They will expand when exposed to moisture. PVDF pellets are more chemical resistant than PEEK pellets. They also withstand moisture better than PEEK pellets and won’t break down when exposed to UV rays.

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.

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.
