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.

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.

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.

Colorants for Plastic Pellets
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.

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. All are FDA compliant for direct contact with food.
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. Agents with a 400° F activation temperature are for use with high-melt-temperature resins such as polycarbonates and polyamides.
Microfine 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 agents produce more gas than microfine agents. Use them to ensure uniform foaming when molding bigger parts.

Plastic Molding Machine Cleaners
Avoid downtime and material waste by quickly purging colors, resins, and carbon build-up from injection molding, blow molding, and plastic extrusion machines. These machine cleaners work with any resin system, so there’s no need to stock a variety of cleaners. They’re also known as purging compounds.
Paste cleaners come in individual packets, so you can drop them directly into your feed or hopper without measuring. Use 1 oz. of cleaner for each inch of screw diameter.
For pellet cleaners, use one to two times the barrel capacity.
