FDA compliant for direct contact with food, these balls are often used to clean screens in vibrating sifters in food, beverage, and other sanitary environments. You can also use them as seals in pumps and check valves. All are made of natural rubber, which is also known as gum rubber and latex rubber.

Metal- and X-ray detectable balls contain metal and chemical additives that will set off metal detectors and show up on X-ray machines if they fall into your line, helping you comply with Hazard Analysis and Critical Control Point (HACCP) programs. The metal additive also makes it easy for magnetic traps to catch the balls—or any piece of them—that fall into a line. All are bright blue, making them easy to spot. These balls do not contain Bisphenol A (BPA), which is a chemical that can contaminate your process lines. Free of plasticizers, they won’t impart tastes or odors to items they come into contact with.

Safely use these balls in food and pharmaceutical environments to clean screens in vibrating sifters or to act as a seal in pumps and check valves. They’re made with metal and chemical additives to set off metal detectors or X-ray machines if they fall into food, helping you comply with Hazard Analysis and Critical Control Point (HACCP) programs. The metal additive also ensures these balls will be caught by magnetic traps. These balls are FDA compliant for direct contact with food, and contain no BPA or plasticizers that could cause contamination. They’re made of polyurethane, which combines rubber’s shock-absorbing properties with the strength of plastic. To withstand rough use over time, these balls are designed to be abrasion resistant.

Loosen fine particles from the grip of vibrating-sifter screens with the bounce of rubber balls. Also use them as seals in pumps and check valves. They’re made from FDA-listed materials for use with food and beverage. Neoprene is also known as chloroprene.

Use these balls as seals in pumps and check valves, or let them bounce inside of vibrating sifters as an effective screen cleaner. Silicone, commonly called polysiloxane, offers good resistance to ozone and salt water.

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.

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. Choose those with a higher melting temperature when more heat resistance is needed; however, they’re not as flexible as the other PVDF pellets. PVDF is also known as Kynar.

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

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.
