Plastic-Acrylonitrile-Butadiene-Styrene (ABS)

Acrylonitrile-butadiene-styrene (ABS) is a thermoplastic synthetic polymer resin. It has a good balance of properties and can be tailored to suit special needs. Its main physical characteristics are: hard and firm. Resin-grade ASS can have bending properties like synthetic rubber (or rubber). Among them, polybutadiene provides good compressive strength, non-crystalline styrene thermoplastics make the addition of ABS easier (more fluid in the mold), and acrylonitrile increases the fastness, hardness, and corrosion resistance. Effective control of these three components allows designers to design the degree of flexibility according to the needs of the final product. Perhaps because of this, ABS can be widely used in household products and white products. Although it is not as tough as other engineering polymers, it can effectively control costs. And you can review more details in our custom plastic parts.

Features of ABS

PP Plastic-Polypropylene (PP)

PP Plastic-Polypropylene (PP) is the cheapest plastic. Because the price is cheap, plastic injection molding companies often try to avoid large-scale production while looking for ways to reduce the price of single products and processing costs. Simply put, it is to find a product that is not only suitable for mass production; use mass production to reduce unit cost, and at the same time, it does not need to meet mass production for high investment and high output.

Features of PP

Colorless and translucent thermoplastic lightweight general-purpose plastic. It has chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties, and good high wear-resistant processing properties.

Applications of PP

Furniture, packaging, lighting equipment, food packaging, table mats, folders, etc.

PP Main Process

injection molding.

Plastic-Polycarbonate (PC)

PC plastic-polycarbonate (referred to as PC) Polycarbonate (PC) is a modern material. The application of polycarbonate in this product is to interpret a typical object and shape. The direct reference to this design may be the wooden ladder found in the basement of your grandma’s house. This product does not use wood but is made of another modern material that is completely suitable for this function. Polycarbonate is as hard as other polymers, yet light in weight, and can provide a variety of colors and post-treatment effects. As a member of a relatively young thermoplastic family, polycarbonate, like many other plastic materials, was accidentally discovered by General Electric Company (GE) in the early 1950s. This material is known for its ultra-clearness and ultra-strongness and is often used as a substitute for glass in applications such as transparency and smoothness.

Features of PC

High strength and elastic coefficient, high impact strength, a wide temperature range of use; high transparency and free dyeability; low forming shrinkage, good dimensional stability; good fatigue resistance; good weather resistance; excellent electrical properties, very Strong high-temperature resistance up to 125C, fire resistance, radiation protection, durable, recyclable and non-toxic.

Applications of plastic polycarbonate(PC):

Home appliance housings (such as computers, TV, etc.), safety helmets, glasses, water cups, baby bottles, kitchen utensils, etc.

Main Process of PC

injection molding.

PU-Polyurethane Technology (PU)

PU is a material like skin, that can breathe and stretch, but it can be shaped into various thicknesses. These characteristics were initially used in the medical and plastic surgery industries and were used as cushion materials for patients in hospitals. Technology is one of the materials applied to the new and more general field of interior goods through experiments. Technology is a combination of liquid and solid at the same time. The liquid can be poured into the mold to obtain the product, that is, other substances can be easily added to it. In the sheet state, the shape of the material can be obtained by embossing or cutting. Compared with water or silicone resin gel, its advantage is that it does not contain a plasticizer, that is to say, the material does not easy to lose its basic characteristics after a long time. It is the only gel that will not crack, harden, or age.

Features of PU

Good pressure dissipation, breathability (good absorption and release), strong recovery ability, easy to mix with decorative materials, strong shock absorption, strong pressure absorption, adjustable hardness, high elasticity, non-fading, can be pasted, Does not irritate the skin and can be cast.

Applications of Polyurethane Technology(PU): 

Bicycle seats, plastic surgery seat cushions, insoles, office chairs, handles of tennis rackets, etc. The PU leather we often say is made of PU plastic.

Main Process of PU

Injection casting, embossing, cutting.

Plastic-Polyvinyl Chloride PVC

PVC may be one of the most widely used plastic materials, ranging from plastic doors and windows in daily life to water pipes, gutters, shoes, cable insulation, toys, injection-molded products, bright bodies, extruded products, and glass assembly, Packaging, credit cards. Wait, there are traces of it almost everywhere, and PVC material is also one of the cheaper plastic materials.

Features of PVC

Flexible, easy to color, has a variety of hardness to choose from, can be extrusion molding, injection molding, and blow molding, can be reinforced with glass fiber, can maintain its characteristics at low temperatures, can be printed, recycled, good Tear and abrasion resistance, good sun and seawater resistance, good oil and chemical resistance.

Applications of Plastic Polyvinyl Chloride(PVC):

Food packaging, electronic products, soft drink bottles, Miller beer bottles, and other products

Main Process of PVC

Injection molding, blow molding, or extrusion molding.

Plastic-Polyethylene Terephthalate (PET)

PET is usually used in the packaging of food and soft drinks. However, because beer is thermally sensitive to oxygen and carbon dioxide, PET is not suitable for beer. There are a total of 5 layers of plastic bottles, and the two layers sandwiched between the main layer of PET are oxygen decay, which can prevent oxygen from entering and exiting. Miller Beer Company, which produced the first plastic beer bottle in 2000, claimed that plastic bottles can keep beer cooler than aluminum cans, and even have the same effect as glass bottles. They can be resealed and are not easily broken.

Features of PET

Recyclable (PET is one of the most recyclable plastic resins), excellent chemical resistance, hard and durable, excellent surface polishing, and good pressure resistance.

Plastic-Cellulose Acetate (CA)

Cellulose acetate products have a warm touch, are anti-perspiration, and are self-luminous. It is a traditional polymer with bright colors and syrup-like transparency. It began to develop in the early 20th century, even earlier than insulating Bakelite. Since cellulose acetate has a marble-like effect, people can often apply it to tool handles, spectacle frames, hair clips, and other products, so it is also one of the most recognized polymers. Using it as a material for hand-made utensils can combine its excellent pressure resistance with a good feel. Other materials, such as polypropylene have better compression resistance and feel more slippery. The self-brightness component in the cellulose acetate material comes from its softness, and slight scratches on the surface can be worn away. It contains cotton and wood (cellulose) components and can be molded by injection, transfer, and extrusion. You can also buy its flake products.
