    • Hollow Plastic Balls are spheres that can float on surface of liquid in open tank and thereby greatly reduce the exposed liquid surface area - up to 90%. Dramatically diminish objectionable fumes and odors. Blanket of spheres also insulates heated liquid reducing evaporation and heat requirements. Ideal for plating tanks and similar open tank installations where the liquid surface can be covered with a blanket of spheres without impeding access to the tank for process purposes. Spheres are hollow and will float on any liquid. No welt or rim on which chemicals can deposit, and being smooth they ensure a much tighter surface cover.

      Types of Hollow Plastic Balls available from Professional Plastics:
    • Polypropylene (PP) is non-toxic and able to withstand continuous working temperatures of 110° C (230°F) Polypropylene is suitable for use in most known chemicals.
    • High Density Polyethylene (HDPE) generally suitable as above but with a continuous working temperature limitation of 80° C. (176° F) softening point about 110° C (230°F). High density polyethylene has better chemical resistance to certain compounds like oil, and other hydro-carbons. Also less stress cracking at low temperatures than polypropylene. Color white translucent except 100 mm, black for outside use. All sizes are blow molded.
    • PTFE Balls (Polytetrafluorethylene) Balls. - PTFE is a non-friction material which is resistant to most corrosive agents and is electrically nonconductive. PTFE is particularly suitable for use in apparatus designed to handle cryogenic liquids and acids. Commonly used in ball seal valves.

    • Nylon Balls are used in a variety of bearing, and seal applications. These balls are precision ground for tight tolerance & are made of solid, high-quality thermoplastic. Nylon 6/6 offers high strength (especially at elevated temperatures), toughness at low temperatures, stiffness, wear and abrasion resistance, low coefficient of friction and good chemical resistance. All Nylons absorb moisture; this increases flexibility and impact resistance. Use for high impact application requiring strength and rigidity. UV light results in degradation over time. Resists hydrocarbons, aromatics, aliphatic solvents, automotive oils and fuels, and refrigerants. Attacked by strong acids, bases, and phenol. Gradually attacked by hot water. Lightweight -- approximately 1/8 the weight of bronze, 1/7 the weight of cast iron, and 1/2 the weight of aluminum -- which reduces both the inertial and static loads and eases the handling of large components during maintenance or replacement procedures.
    • Color: Natural (yellow-cream color)
    • Torlon® balls are used for high-strength, wear-resistant ball bearings.
    • Excellent for High-Load Recirculating Ball Bearings.
      Automotive Application: Torlon Check Balls for 4-Wheel-Drive Vehicle Transmissions
      The durability of high-torque automatic transmissions was improved when Chrysler product development engineers specified Torlon® poly(amide-imide) resin for the check balls. The resin was selected for multiple variations of three- and four-speed transmissions coupled to the Magnum Engine product line. The check balls withstand system pressures, and provide excellent sealing surfaces without causing metal damage, and without adverse reaction to transmission oil at temperatures approaching 300°F.
      Boating/Sailing Application: Headsail Roller Furlings:
      Torlon® ball bearings in each swivel carry the load so that the sail furls freely. An over center halyard attachment can distribute the load uniformly to each ball bearing, providing a smooth rotation.
      Small Boat Traveller Cars move freely, even under high non-vertical loads. Low-load dinghy cars use Delrin Bearings, while hi-load cars for large dinghies, keel boats and offshore boats to 27 ft (8m) use Torlon® balls to increase working load. Torlon balls provide maximum load carrying ability.

    • Acrylic Balls (Polished) - Round Clear Cast Acrylic Polished Balls
      Acrylics (Polymethyl-Methacrylate) is an amorphous thermoplastic which is optically transparent, unaffected by moisture, and offers a high strength-to-weight ratio. Common trade names of acrylic include Plexiglas®, Lucite®, and Acrylite®.

      These acrylic balls offer high light transmittance with a Refractive Index of 1.49 and can be easily heat-formed without loss of optical clarity. Prolonged exposure to moisture, or even total immersion in water, does not significantly effect the mechanical or optical properties of our acrylic balls. These acrylic balls have been UV stabilized for good weatherability and resistance prolonged sunlight exposure. Acrylic balls are unaffected by aqueous solutions of most laboratory chemicals, by detergents, cleaners, dilute inorganic acids, alkalis, and aliphatic hydrocarbons -- however, acrylics are NOT recommended for use with chlorinated or aromatic hydrocarbons, esters, or ketones.

      These are beautiful, crystal-clear acrylic spheres. Use as decorative accents, knobs, or feet on acrylic boxes. They have a polished surface that is flawlessly smooth. Crystal clear highly polished acrylic balls. Great for many types of projects and decorations.

    • Excellent Frac Ball Material !!

    • Exploiting tight gas reservoirs requires the ability to fracture wells according to production requirements. Most require multiple transverse fractures at specific locations within the horizontal well. In order to maximize productivity, the creation of multiple fractures is of critical importance.

      One popular method for creating fractures is the use of frac ports & sliding sleeves. Openhole packers isolate different sections of the horizontal well. A sliding sleeve is placed between each packer pair and is opened by injecting a ball inside the borehole. Typically, a compleiton string is placed inside the well. The string include frac ports and open hole packers spaced to specifications. The spacing between packaers may be up to several hundred feet. The packers are actuated by mechanical, hydraulic or chemical mechanisms. In order to activate each sleeve, a properly sized ball is pumped along with a fracturing fluid inside the well. Each ball is smaller than the opening of all of the previous sleeves, but larger than the sleeve it is intended to open. Seating of the ball exerts pressure at the end of the sliding sleeve assembly, causing it to slide and open the frac ports. Once the port is opened, the fluid is diverted into the openhole space outside of the completion assembly, casuing the formation to fracture.

      At the completion of each fracturing stage, the next larger ball is injected into the well, which open the next sleeve, and so on, until all of the sleeves are opened and multiple fractures are created in the well. The main advantage of this completion technique is the speed of operation which also reduces costs.

      Typically, ball sizes are staged in .500" or .250" increments. It is improtant to understand that this process is not without risk of failure and should only be undertaken after considerable research and consideration. Frac plugs are designed to seal from above the plug only. Each plug uses a plastic fracturing ball that seals on top of the mandrel. The fracturing ball is free to float off the mandrel with pressure or flow from below the plug. This allows immediate flowback of all zones following treatment.
    • Delrin® Acetal POM Balls are used in a variety of bearing, and seal applications. These balls are precision ground for tight tolerance & are made of solid, high-quality thermoplastic.
    • Tolerance ±.001" for all sizes.
    • Standard Color: Natural (white). - Black may be produced on a special order basis.
    • Clear Acrylic Cabochons - (Acrylic Half Balls) These clear acrylic cabochons are lightweight when compared to glass. Acrylic cabochons (cabs) are solid, transparent, polished and void-free. They are flat on one side and convex on the other. They are made of Plexiglass and are produced by injection molding. Injection molding means that each cab has an injection gate mark, or small blemish at one point around the edge.
