POLYURETHEANS

Polyurethanes are one of the most versatile plastic materials. It is mostly known as a form of flexible foam that is one of the most popular material in industrial machinery area as well as for many purposes with its main ingredients such as polyether, polyester, and isocyanate. It's application of using these main ingredients when manufacturing products are diverse.

 

Polyurethanes Applications

 

Explore the many uses of polyurethanes, which range from flexible foam in upholstered furniture to rigid foam as insulation in walls and roofs, to thermoplastic polyurethane used in medical devices and footwear, to coatings, adhesives, sealants and elastomers used on floors and automotive interiors.

​

Characteristics

  • Wide range of hardness: Polyurethanes has a wide range of hardness with good elasticity

 

  • Tear Resistance: Polyurethanes possess high tear resistance along with high tensile properties.

 

  • High Load Bearing Capacity: Polyurethane has a high load capacity in both tension and compression. Polyurethane may undergo a change in shape under a heavy load, but will return to its original shape once the load is removed with little compression set in the material when designed properly for a given application.

 

  • Abrasion & Impact Resistance: For applications where severe wear prove challenging, polyurethanes are an ideal solution even at low temperatures.

 

  •  Flexibility: Polyurethanes perform very well when used in high flex fatigue applications. Flexural properties can be isolated allowing for very good elongation and recovery properties.

 

  • Strong Bonding Properties: Polyurethane bonds to a wide range of materials during the manufacturing process. These materials include other plastics, metals, and wood. This property makes polyurethane an ideal material for wheels, rollers, and inserts.

​

Other than above characteristics, other advantages of polyurethanes include having

•  Resistance to water, oil and grease,

•  Exhibit good electrical insulating properties

•  Wide resiliency range

•  Color ranges

•  Short production lead times

•  Mold, mildew and fungi resistance

MC NYLON

The material, nylon monomers are polymerized. This maximized the features of extrusion and injection moulding that were previously not found.  Compared to nylon 6, the molecular weight is 10 times higher, with improvements of the degree of crystallinity.

 

 

Characteristics

  1. Exhibit excellent wear resistance and self-lubrication

  2. Exhibit excellent mechanical durability, corrosion resistance and fatigue resistance

  3. Chemical resistance (e.g. organic solvent, alkaline)

  4. Continuous use of temperature = 120℃

  5. Noise and corrosion protection (e.g. Car wheels, pallets, bearings, agricultural parts, printing press parts, liner insulation etc)

(PolyEthylane)

Polyethylene is a thermoplastic polymer with variable crystalline structure and an extremely large range of applications depending on the particular type. It is one of the most widely produced plastics in the world. It is widely known for its unique characteristics of ‘lightweight’ and ‘corrosion resistance’ including its advantages of reacting to the heat without significant degradation. Therefore, Polyethylene is also known as “thermoplastic”.

​

Characteristics

  1. Exhibit excellent chemical resistance, acid resistance, and self lubrication

  2. Exhibit excellent wear resistance and fabrication

  3. Free of toxic chemicals

  4. Exhibit good low temperature toughness (to -60℃)

  5. Chemical composition is known as following: 

  • HDPE (High Density Polyethylene)

  • LDPE (Low Density Polyethylene)

 

Applications

e.g. Pipes, rollers, glass caps

(Polypropylene)

Polypropylene is a tough and rigid, crystalline thermoplastic produced from propene (or propylene) monomer. It is the second most produced plastics and carries the lightest weight amongst the plastic properties.

 

Advantages of polypropylene:

•    It is a relatively inexpensive material

•    It possesses high flexural strength because of its semi-crystalline nature

•    It has a low coefficient of friction

•    It is very resistant to moisture

•    It has good chemical resistance over a wide range of bases and acids

•    It possesses good fatigue resistance

•    It has a good impact strength

•    It has a good resistance to electricity and is thus a good electrical insulator

•    It is more easily repaired from damage

 

Disadvantages of polypropylene:

•    It has a high thermal expansion coefficient which limits its high-temperature applications

•    It is susceptible to UV degradation • It has poor resistance to chlorinated solvents and aromatics

•    It is known to be difficult to paint as it has poor bonding properties

•    It has a high flammability

•    It is susceptible to oxidation

 

 

Characteristics

Semi-rigid, translucent, good chemical resistance, tough, good fatigue resistance, integral hinge property, good heat resistance.

ETC

ABS resins are hard, rigid, and tough, even at low temperatures.

 

PET is a hard, stiff, strong, dimensionally stable material that absorbs very little water. It is high in clarity and food contact safety and resistant to acids.

 

POM has high tensile strength, stiffness, resilience, fatigue endurance, and moderate toughness under repeated impact. Acetal homopolymers have excellent creep-resistance, and the highest fatigue endurance of any unfilled thermoplastics. A low coefficient of friction makes their abrasion resistance excellent. Low moisture absorption. Thus, it is widely used in electricity, cars, machinery and many other areas. 

 

Other than above classifications, we also use PEEK / PCTFE / PTFE / PVDF / 6N in order to meet customers’ request and demand, and choose the most appropriate materials to produce the products.
