1.ABS engineering plastics

Acrylonitrile-butadiene-styrene (ABS) is a thermoplastic synthetic polymer resin that has a good balance of properties and can be tailored to suit specific needs. Its main physical characteristics are: hard and firm. Resin grade ASS can have bending properties like elastomer (or rubber). Among them, polybutadiene provides good compressive strength, non-crystalline styrene thermoplastics make it easier to add ABS (more flow in the mold), and acrylonitrile increases the fastness, hardness and corrosion resistance of ABS.

Effective control of these three components allows the designer 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.

2. Polypropylene (PP)

The design work of PP is not limited to creating beautiful shapes and perfect functions, but often to find ways to reduce the price of single products and processing costs while avoiding mass production. Simply put, it is to find a product that is suitable for large-scale production.

It is widely used in all aspects of product design, from packaging, lighting equipment to indoor supplies. However, one has not been able to apply this material entirely through the thermoforming process.

3. Polymethyl methacrylate (PMMA)

Acrylic was developed in the 1930 s, when it was mainly used for the top turning device of safety glass. The acrylic material was first registered in 1934 as the well-known plexiglass. Transparency and lightness are perfectly combined, making it an interesting new type of plastic. By the 1960 s, this material was discovered by avant-garde furniture designers and used in indoor environments such as modern furniture.

Since acrylic can provide a variety of color options, its function is naturally expanded from lighting equipment to the manufacture of company logos. All international brands now use this material for signage. The acrylic surface is hard and is easily recognized as glass from a distant perspective. It can be manufactured into thin sheets by casting and extrusion molding to meet the requirements of different applications. The cast acrylic sheet can be used as a high-quality glass and is suitable for mass production.

The high molecular weight makes it very strong, flexible and easy to handle and manufacture. This casting manufacturing method is especially ideal for large products and small batch coloring. The extruded sheet has a lighter molecular weight, so it is easy to pump and form. The extrusion molding process makes the product have excellent thickness resistance and is also very cheap for mass production.

Material characteristics:

A variety of manufacturing and processing methods, easy to process a variety of transparent, translucent and opaque and color, surface effects to choose from, excellent chemical resistance and weatherability, excellent chemical resistance and weatherability, high printing adhesion, can be completely recycled, excellent visual clarity, special color creativity and color matching, high surface hardness, good durability.

4. Cellulose acetate (CA)

Cellulose acetate products are warm to the touch, anti-sweat, and can self-glow, it is a traditional polymer with bright colors and syrupy transparency. It developed from the beginning of the 20th century, even earlier than insulated bakelite. Because cellulose acetate has a marble-like effect, it can often be used in products such as tool handles, eyeglass frames and hairpins, so it is also one of the most easily recognized polymers.

Use it as a handmade tool material, you can combine its excellent pressure resistance and good feel. Other materials, such as polypropylene, have better pressure resistance, but feel more slippery. The self-shining component of 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 casting, rotary casting and extrusion. You can also buy its flake products.

5. Polyethylene terephthalate (PET)

PET is commonly used in food and soft drink packaging. However, due to the heat sensitivity of beer to oxygen and carbon dioxide, PET is not suitable for beer. The plastic bottle has a total of 5 layers, and the two layers in the main layer PET are oxygen decay, which can prevent oxygen from entering and leaving. Miller Brewery, which produced the first plastic beer bottle in 2000, claims that plastic bottles keep beer cool better than aluminum cans, even resealing and not breaking as well as glass bottles.

Material characteristics:

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

7. Polyurethane Technoge(PU)

Material like skin, it can breathe and stretch, but it can be molded into shapes of various thicknesses. These properties were initially used in the medical and orthopedic industries as a material for cushions given to hospital patients. Technoge is one of the materials that has been experimentally applied to the new and more general field of interior products.

Technoge is a combination of liquid and solid at the same time. The product can be obtained by pouring the liquid into a mold, 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 based gels, the advantage is that they do not contain plasticizers, that is, the material is less likely to lose its basic properties over a longer period of time. It is the only gel that does not crack, harden or age.

8. Silicone Polymer

In 1943, a Scottish engineer, James Wright, tested a mixture in a test tube at the General Electric Company's laboratory in Connecticut, USA. He accidentally mixed boric acid and silicone oil together to "polymerize" them ". Wright threw some of this adhesive dispenser to the ground as he sucked it from the test tube. Surprisingly, this substance bounces off the floor, and the elastic sludge is born.

Wright decided to find a practical use for his invention, and finally SillPuttyTM plasticine made its debut at the International Toy Festival in New York in 1950. After persistent efforts, some large toy dealers decided to distribute SillPuttyTM plasticine, and what happened after that is well known.

Material characteristics:

Under the gravity of the earth, it gradually flattens, with a bounce degree of 80% (relative to the position left behind). It is an expansive compound that is solid and holds its shape when rapidly pressurized. When gradually pressurized, it is liquid and easy to mold. Cooling can increase bounce. After being made into a boat shape, it can float on the water surface. After being made into a ball shape, it will sink. It is non-toxic, non-irritating, highly elastic and a variety of colors.

Typical use: No other applications for the time being

9. Polycarbonate (PC)

Polycarbonate (PC) as 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 your grandmother's basement. This product does not use wood, but is made of another modern material that is perfectly suitable for this function.

Polycarbonate is as hard as other polymers, while lightweight, and can provide a variety of colors and post-treatment effects. A member of a relatively young thermoplastic family, polycarbonate, like many other plastic materials, was accidentally discovered by General Electric (GE) in the early 1950 s. This material is known for its ultra-clarity and ultra-strength, and is often used as a substitute for glass in applications such as transparency and smoothness.

Material characteristics:

It can provide a series of good color clarity, simple processing procedures, and very good impact resistance. It can provide fully transparent, translucent and opaque appearance effects. Even at high temperatures, its dimensional stability is also very strong. High temperature resistance is up to 125C. Fire protection, radiation protection, durable, recyclable, non-toxic
