Plastic Balls

Plastic balls are lighter than steel balls and have characteristics of being acid proof, alkali proof, heat and electric insulative, and antimagnetic. There are many kinds of plastic, and the proper plastic balls for customers requirement are used in many different industries such as electric, automobile, medical equipment, industrial machine, etc. plastic-p01.jpg

Types of Engineering Plastic Balls

plastic_pp-p01.jpg Polypropylene balls (PP-BALL)
Nowadays polypropylene is multi-purpose plastic and has established a position as an engineering plastic. Since it is light weight and has superior mechanical characteristics and thermal resistance, use for the parts of the automobile and home electric appliances has been increasing. Another reason that the use of the polypropylene is increasing is the ease of which it can be recycled and it does not discharge noxious fumes when it is burnt for the disinstallation.

Other than acrylic, there are polycarbonate, plystyrene, polyvinyl chloride other than acrylic for the translucent plastic currently available in market. However, no one beats acrylic plastic when it comes to the translucency, light resistance and mechanical characteristics.
plastic_pa-p01.jpg Nylon balls (PA-BALL)
Polyamide is a heat reversible crystalline plastic known as Nylon. It is the trailblazer of the synthetic fiber and the oldest plastic in history.
plastic_pom-p01.jpg Polyacetal balls (POM-BALL)
Polyacetal was developed by the basic concept of engineering plastic "Plastic that has characteristics of alternative metal". It has the characteristics beyond the bound of common sense of existing plastics, and has high physicality balance among the various engineering plastic. In addition to the frictional characteristics, Polyacetal has a special characteristic of being self lubricative which can not be seen in other engineering plastic except for fluoric plastic.
plastic_pc-p01.jpg Polycarbonate balls (PC-BALL)
Polycarbonate is a plastic usually abbreviated as PC. Within the heat reversible plastics, it has the highest impact strength which is 150 times stronger than tempered glass. This is the highest impact strength of all transparent plastics. This is thermal resistant plastic and one of the 5 major engineering plastics.

Super Engineering Plastic Balls

There is no fixed definition but the plastic that has more than 60MPa tensile strength, more than 2GPa elasticity, more than 50J/m impact strength, continuous using temperature is more than 100°C and low creep is called engineering plastic. Within engineering plastics, those who have more than 150°C of heat transformation temperature and superior mechanical characteristic are called super engineering plastic (High performance plastic). enpla-p01.jpg

Super Engineering Plastic Balls

enpla_ptfe-p01.jpg Teflon balls
Teflon is the plastic that has fluorosis molecule and the official name is polytetrafluoroethylene and it has high chemical resistance, weather resistance, electrical insulative, friction coefficient (lubricity) compared with other heat reversible plastics. Fluoric plastic (PTFE) is the essential material for semiconductor, precision and high-tech industries.
enpla_peek-p03.jpg Peek balls
The official name of Peek is polyetheretherketone, and is a totally new super engineering developed by ICI. It is very pure material with high thermal resistance, mechanical characteristics, chemical resistance, flame resistance, safety and sanitary (UL94V-0), low smoke amount upon burning, low elution of gas/ion/molucules.
enpla_pi-p01.jpg Vespel balls
Vespel is a thermosetting plastic that has excellent thermal resistance and mechanical characteristics. The continuous using temperature of Vespel is 250 - 300°C and is a symbolic existence of alternative metal material. However, the use is limited to airplane and aerospace since it is very expensive. It is starting to be used for the multi-layer computer circuit board, VTR, flexible print circuit board, precision instrument. Vespel has the highest thermal resistance and friction resistance and it does not have disadvantages that metal has. So it is expected to be used for a wide variety of areas as a new material. * Vespel is the registered trademark of U.S. Dupon.
enpla_uhmwpe-p01.jpg Super high-molecular-weight polyetherene balls
The chemical composition of the super high-molecular-weight polyetherene is exactly the same as the generic polyetherene but the amount of molecules is more than 10 times of the generic polyetherene and is classified into one of the engineering plastic that is targeted for the structural/functional parts. In addition to the regular grade, bridged modification using peroxide and reinforcement using glass fiber and carbon fiber has been done.
