AS (Acrylonitrile Styrene)

    • Characteristics: AS is a transparent material known for its chemical stability and weather resistance. It has slightly lower heat resistance than ABS but offers higher transparency and glossiness.
    • Advantages:
      • High transparency and excellent gloss, making it popular for products requiring a see-through effect.
      • Good rigidity and hardness, suitable for manufacturing various household items and containers.
      • Relatively good chemical resistance, suitable for applications involving certain chemicals.

PC (Polycarbonate)

    • Characteristics: PC is a high-strength engineering plastic with excellent impact resistance. It also has very good transparency, heat resistance, and weatherability.
    • Advantages:
      • High strength and outstanding impact resistance, maintaining good performance even at low temperatures.
      • High transparency, suitable for making transparent protective gear and eyewear.
      • Good temperature and weather resistance, suitable for long-term outdoor applications.

ABS (Acrylonitrile Butadiene Styrene)

    • Characteristics: ABS is a widely used thermoplastic with good mechanical strength and overall properties, balancing rigidity, toughness, and hardness.
    • Advantages:
      • Excellent overall mechanical properties, especially great toughness and hardness.
      • Smooth surface, easy to color and paint, suitable for producing aesthetically pleasing products.
      • Good processability, can be processed by injection molding, extrusion, and other methods.

Flame-Retardant ABS

    • Characteristics: This is a material based on standard ABS with added flame retardants to improve its safety performance in high-temperature environments such as fires.
    • Advantages:
      • Retains all the benefits of standard ABS, such as good mechanical properties and processability.
      • Enhanced flame retardant properties, meeting specific safety requirements like flammability standards in the electronics and electrical industries.
      • Maintains good physical and chemical properties while increasing the safety range of the material’s use.


Types of Silicone: Silicone can be categorized into two types: organic silicone and inorganic silicone.

Silicone Grades:There are two main grades of silicone: Grade A and Grade B.

Grade A: Food and medical grade.
Grade B: General industrial grade.


Processing Techniques:

Compression Molded Silicone Products: These are typically produced by placing solid silicone raw material, along with a curing agent, into a high-temperature mold and applying pressure using a curing machine. The high temperature and pressure result in the solidification and shaping of the silicone product. The hardness of compression molded silicone products usually falls within the range of 30°C to 70°C. The color of the product can be adjusted using color paste according to color codes. The shape of the mold determines the final shape of the compression molded silicone product. This method is widely used in the silicone industry.

Extruded Silicone Products: These are typically produced by extruding silicone through a machine to form the desired shape. Extruded silicone products often have a long, tubular shape and can be cut to the desired length. However, the shapes that can be achieved through extrusion are somewhat limited. Extruded silicone products find extensive use in medical devices and food machinery.

Liquid Silicone Products: Liquid silicone products are created through injection molding of liquid silicone. These products are soft, and their hardness can range from 10°C to 40°C. Due to their flexibility, they are widely used in applications such as simulated human organ models and medical silicone breast pads.
