Feature

Delrin (Polyoxy-Methylene), also known as Acetal, Polyacetal, and POM, is an engineering thermoplastic commonly used for precision parts that require high strength, hardness and rigidity. It is a tough material with a low coefficient of friction and high abrasion resistance. It has good electrical and dielectric properties, low water absorption. Naturally white in color it does accept opaque colors well and can be polished to a shine. Delrin is typically difficult to bond but can be bonded with epoxies, polyurethanes and cyanoacrylates (superglue). It has good chemical resistance but is sensitive to mineral acids, chlorine, and alkaline degradation.

Feature

Polypropylene balls are featured by a low weight, good mechanical characteristics and corrosion, fatigue and collisions resistance. They are resisting to heat and they are excellent electric insulators. They are floating into water. Additives can be added to avoid degradation phenomena causing to a long exposure at sun light (UV radiation absorption). It is a recyclable material. polypropylene balls are resisting into not concentrated acids, alkalis, alcohols, oils, greases and most inorganic compounds. Fair resistance in aromatic hydrocarbons, they are not resistant in contact with halogens. They provide corrosive phenomena even in presence of concentrated acids and oxidizing agents at high temperature.

Application 

Low load bearings, special valves, check valves, floating valves, fluid level indicators, carburetors, flow meters, chemical, medical and laboratory devices, blood transfusion kits.

Material 

NYLON 6/NYLON 6.6 (PA 6/PA 6.6)

Size

1.5mm-50mm

Grade 

G0-G3 (0.01-0.05mm)

Density

Around: 1.1g/cm3

Feature

Semicrystalline thermoplastic Nylon 6/Nylon 6.6 polymer balls, they provide low weight, high corrosion, wear and abrasion resistance. They are auto lubricant and with good ductility, toughness and electric insulating properties. Useful even for high temperature applications. Nylon balls are insolvable into diluted mineral acids and in most organic acids. They are resisting to alkalis, petroleum products, greases, inorganic salt solutions, low gradation alcohols, motor oil, transmission fluids, methanol, ketones, esters. They do not resist to strong acids and basis.

Application 

Special valves, low load bearings, flow meters, switches, handgrips, medical and industrial applications.

Material

Teflon balls (polytetrafluoroethylene)

Size

1mm-60mm

Grade

G0-G3 (0.01-0.05mm)

Density

Around: 2.2/cm3

Feature 

Low weight fluorinated semicrystalline polymer balls, they provide exceptional corrosion resistance and are used into high temperature applications. Mechanical and wear resistance properties are lower than other plastic materials. Good electric insulators, they are auto lubricant. Teflon properties change if they are exposed to electromagnetic radiations.

Application 

Ball bearings, special valves (very aggressive environments), measurement and medical instruments, appliances. They are used into foodstuff, paper, chemical, electronic, pharmaceutical industry.

Material

Polyetheretherketone, PEEK

Size

3mm-60mm

Grade

G0-G3 (0.01-0.05mm)

Density

Around: 1.3/cm3

Feature 

High performance semi-crystalline thermoplastic balls, they provide high mechanical properties, dimensional stability and excellent wear and abrasion, corrosion, high temperature and gamma radiation resistance. The high temperature resistance decreases considerably in case the material is charged by heavy loads. Unstable to UV radiations. PEEK balls are resisting in contact with most solvents (organic compounds, salts, oils), hot waters and high temparature steams. They are not resisting against strong acids (concentrated nitric acids, sulphuric acids), halogens and some aromatic hydrocarbons.

Application 

Special bearings, pumps and valves, components for chemical, electronic and mechanical industry when high mechanical characteristics and corrosion resistance properties are demanded.
